    Notes: Although flexible specialization is regarded as one of the hallmarks of industrial districts, its consequences for firm performance have not attracted much empirical attention. Using event-history data on a complete population of textile-clothing firms in Baden-Württemberg in the Reutlingen (Germany) district from 1946 to 1993, this paper tests the proposition that specialized firms have a survival advantage over more integrated firms. Logistic regression models of failure probabilities show that, contrary to predictions derived from the district model, horizontally and vertically integrated firms have outlived more specialized firms. This study demonstrates the importance of dynamic research designs that incorporate information on strategic differences in a complete population of district firms, observed over an extended time frame.

    Nuclear Power Plants and Residential Housing Prices (1997)

    Notes: Nuclear power plants can theoretically influence property values through a number of different channels. The public perception of risk associated with the potential hazard from the operation of a nuclear reactor and the storage of nuclear waste may lead to lower bids on properties in close proximity to the plant. In contrast, workers at the plant may be less concerned with any potential hazards, and may actually value being in proximity to the workplace. Hence, one cannot a priori sign the distance gradient of homes in the vicinity of a nuclear power plant. In this study, a hedonic model coupled with geographic information system (GIS) techniques is used to estimate housing price surfaces around two nuclear power plants in California. The use of GIS software allows more potential influences to housing prices to be accurately incorporated than previously included in hedonic studies. Based on the evidence from the plants chosen, these findings do not support the contention that negative imagery surrounding nuclear power plants or stored nuclear waste has a significant detrimental influence on residential home prices in the immediate vicinity of these facilities.

    The Influence of Plant Profitability on Plant Closures in Multi-locational Firms (1997)

    Notes: This paper explores the effect of plant profitability on the closure decision in multi-locational manufacturing firms where the firm is selecting between different sites undertaking similar production activities. The paper draws upon a new interview survey of large multi-locational manufacturing firms. Analysis of the interview data shows that plant profitability is the key to understanding only one-third to one-half of selective closures and that decisions taken by subsidiaries are more likely to rely on plant profitability measures than decisions taken at the corporate head office. In analyzing a regional economy, a poor level of plant profitability is indicative of a plant at risk of closure but the absence of such a characteristic is not necessarily an indication of an assured future for a plant.

    Vacancy Dynamics and Labor Market Efficiency in the Dutch Labor Market (1997)
    Oxford, UK : Blackwell Publishing Ltd
    Growth and change 28 (1997), S. 0 
    Details
    ISSN: 1468-2257
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Geography , Economics
    Notes: This paper focuses on cyclical and regional variations in vacancy dynamics in labor markets with persistent imbalances between demand and supply. In particular the so-called matching approach is used to investigate labor market efficiency across regions and over the business cycle. In this matching approach the relationship between the flow of filled vacancies and regional stocks of unemployed job seekers and vacant jobs is specified in a “search production” function. The matching approach is applied to the Dutch labor market, which is characterized by strong disequilibria and persistent regional differences in unemployment and vacancy rates. To explore the development of these regional imbalances from a demand side perspective, the dynamic structure of regional data on vacancies is analyzed over the business cycle. The movements of vacancy duration and the change in the vacancy stock over time appear to be similar across Dutch regions. Moreover, an investigation of the structural causes of regional variations in vacancy duration via shift-share analysis makes clear that regional differences in sectoral composition of unfilled vacancies do not contribute to regional differences in vacancy duration in the period 1989–93. Estimation results of a matching model reveal that there are no region-specific differences in labor market efficiency to produce filled vacancies. The ratio of vacancies to unemployment appears to be the critical determinant of the matching process in the Dutch regions. Another general (non region-specific) finding is that the estimated labor market efficiency increases during recessionary and recovery periods while it decreases during an economic boom.

    The Impact of NAFTA on Mexico's Environmental Policy (1997)

    Notes: A major controversy during the debate over the North American Free Trade Agreement focused on the impact of NAFTA on Mexico's environment. This paper examines the evidence of impact specifically on Mexico's environmental policy. Criteria of impact are developed, and comparisons made for three periods: before 1990 as the baseline period; 1990-93 when NAFTA was being negotiated; and beginning in 1994 when NAFTA came into effect. Much evidence indicates that Mexico's environmental policymaking and enforcement did improve in the early 1990s while NAFTA was being debated. Some evidence also suggests that the NAFTA-influenced environmental commitment was sustained during the 1995 financial crisis. Thus, it is concluded that NAFTA has contributed significantly to Mexico's environmental policy.

    Notes: This paper develops a model of the relationship between the solid waste recycling activities of industrial-commercial-institutional (ICI) firms and two sets of explanatory variables: characteristics of the firm and characteristics of the waste materials. The model is tested for six types of waste material (paper, paperboard, plastic, glass, wood, and metal) using logistic regression analysis and drawing on waste quantity and composition data collected from a sample of over 400 ICI firms in metropolitan Toronto. The percentage of firms recycling materials ranged from a high of 46 percent for paperboard to a low of 8 percent for plastics. In all of the models tested, quantity of waste material produced was found to be a significant explanatory variable in determining whether a firm will recycle that material. Other variables which were found to be significant in explaining recycling of some, but not all, material types were floor space of the firm, and type of economic activity. Despite theoretical support for its inclusion, employment was not found to be significant in any of the models.

    Integrating Econometric and Input-Output Models in a Multiregional Context (1997)

    Notes: This paper explores the extension of integrated econometric/input-output models from a single to a multiregional context. A number of methodological issues associated with existing treatments of extraregional relations in both traditional multiregional econometric models and the more recent single region integrated models are discussed. A series of new approaches are introduced that rely on the integration of econometric and input-output methods to specify extraregional linkages. A comparison of these alternative modeling approaches is undertaken using employment series for 5 regions in Southern California. The forecasting accuracies are evaluated in a series of out-of-sample forecasting experiments. The findings suggest that the forecasting performance of the multiregional extensions of the integrated approach is competitive with the performance of single region implementations. The performance of the alternative multiregional approaches is found to be relatively more sensitive to regionalization of the IO component and the level of industrial disaggregation than to the incorporation of distance in the specification of the multiregional linkages.

    Notes: This paper explores the role of environmental factors in the contract-allocation decisions of European and North American multinational corporations (MNCs). Particular attention is given to the motivations and experiences of selected MNCs that have recently adopted environmental policies to guide specific aspects of their international purchasing procedures. The results of a pilot survey of 12 MNCs suggest that environmental issues are beginning to enter into the strategic decision-making fields of corporate planners, notably with regard to supplier selection and evaluation. The paper concludes with a brief discussion of possible directions for future empirical research.

    Notes: As concern for environmental protection is growing within all sectors of society, industrial firms are being forced to become more accountable for their actions. Government policies, in the form of environmental standards, have been designed to reduce the level of toxic pollutants being discharged by firms. In order to comply with these standards, firms must either change the nature of their production processes or employ technologies that reduce the level of effluent being discharged. This paper investigates the role of environmental policy in driving firms to adopt pollution control technologies. The policy addressed is the Province of Ontario's Municipal Industrial Strategy for Abatement (MISA) which seeks to compel firms to reduce discharges of industrial effluent through the application of the “Best Available Technology Economically Achievable.” The impact of this policy instrument on the adoption of pollution control technology in the Ontario organic chemical industry is examined. The analysis is based on interviews with firms in the chemical industry which reveal that environmental policy has played a central role in inducing firms to adopt pollution control technologies. The paper draws on literature about technology diffusion, especially the relationship between suppliers and users of technology, and examines the process through which environmental technology is transferred to regulated firms. The relationship between the suppliers and users of technology is strong, especially between the large multinational users and smaller independent domestic technology suppliers.

    Notes: This paper examines the role of internal and external research, design and development (RD&D) activity in the innovation performance of New York State manufacturing firms in the scientific instruments sector. Survey data from a sample of 204 small and medium-sized companies suggest that the incidence of successful product development is higher among firms that combine in-house RD&D with technical support from independent specialists. Significantly, firms that supplement their in-house innovation efforts with outside talent are found to exhibit better commercial performance than their counterparts that operate on the basis of either internal or external technical resources alone. The paper concludes with a brief agenda for future empirical research on the conditions that support product innovation among small and medium-sized firms.

    Notes: This paper evaluates the influence of residential density on commuting behavior across U.S. cities while controlling for available opportunities, the technology of transportation infrastructure, and individual socio-economic and demographic characteristics. The measures of metropolitan and local density are addressed separately. It is suggested that metropolitan residential density serves principally as a surrogate for city size. Markets react to high interaction costs found in large cities by raising density rather than density being a cause of those high costs. Local residential density measures relative location (accessibility) within the metropolitan region as well as indexing the level of congestion. Regressions are conducted to predict commuting time, speed, and distance, by mode of travel on a cross-section of individuals nationally and city by city. The results indicate that residential density in the area around the tripmaker's home is an important factor: the higher the density the lower the speed and the shorter the distance. However, density's effect on travel time is ambiguous; speed and distance are offsetting effects on time. The paper suggests a threshold density at which the decrease in distance is overtaken by the congestion effects, resulting in a residential density between 7,500 and 10,000 persons per square mile (neither the highest nor lowest) with the shortest duration auto commutes.

    Notes: Among the environmental issues that have come to dominate social concerns, the amount of packaging sent for disposal in landfills has gained increased prominence in Canada, with the issuance in 1990 of the National Protocol on Packaging (NAPP). Recognizing the increased demands for improved environmental performance on the part of corporations, this study seeks to understand why some companies respond more quickly than others to concerns about packaging-waste reduction. The paper links concepts found in the Corporate Social Responsibility and Innovation Theory literatures, in order to explore corporate response patterns to pressures for change and to develop a measure of corporate performance with regards to packaging-waste reduction efforts. Bivariate and linear logit analyses of data were undertaken, and confirm that variations in a company's response pattern can be explained in terms of factors such as company size, product orientation, and existence of an environmental affairs function, as well as external policies, such as NAPP.

    Notes: This paper considers the behavior of actors in real estate markets in the face of environmental uncertainty. Environmental legislation has increased in scale and scope with obvious implications for property markets. Developers, investors, occupiers, and lenders may all be affected by changing environmental standards. Any factor that creates valuation uncertainty will have major impacts. Blighted sites and properties will be shunned, while existing real estate portfolios will be adversely affected. A survey of UK property practitioners on their attitudes to environmental hazard reveals that firms seem pessimistic as to their ability to quantify and model the economic and investment implications of environmental risk. There are concerns here for the wider economy and for the business community through supply-side constraints and suboptimal location. There are implications, too, for local and regional regeneration strategies as whole areas may be blighted by potential contamination. There may be mispricing and arbitrage opportunities in relation to such assets that can be exploited through first mover advantage by firms willing and able to develop effective risk-sensitive appraisal models.

    Notes: The amenity value to Kentucky residents from horse farm land was estimated using both the contingent valuation method and the hedonic pricing method. The hedonic pricing model included both the housing and labor markets. A value function estimated from dichotomous choice contingent valuation responses showed that the value of a change in the level of the horse farm amenity was sensitive to the size of the change, with no evidence of value that is independent of the size of the change. The two methods generated estimates of the external benefits from horse farm land that were within 20 percent of each other.

    Notes: A common argument advanced in the non-metropolitan counties of the US West is that the Endangered Species Act (ESA) can have, and has had, a devastating effect on local economies. However, to date, there has not been a systematic empirical analysis of the ESA's effect on local economies. This paper reports on such an analysis. Based on a sample of all 333 non-metropolitan counties in the eleven-state West, the statistical effect of the listing of threatened and endangered species on county employment growth between 1980 and 1990 is estimated. The paper's primary finding is that the hypothesis that endangered species listing has had a negative effect on the non-metropolitan county economies of the US West is not supported by the data.

These “linked” migrants contrast to “independent migrants” who move as individuals or intact groups and set up their own households at the destination. Using U.S. Census Public Use Micro Sample data, this paper first shows that, in the 1985-90 period, about 45 percent of all Black interstate migrants were independent, compared to 38 percent who were linked to housing at the destination and 17 percent who moved into group quarters. Second, a multinomial logit model, incorporating individual and state-level variables, is specified that contrasts the determinants of independent and linked migration. Tests show that independent migration can be modeled with classic migration determinants, including individual educational and occupational resources, labor market conditions at the destination, and public goods at the destination including the level of welfare payments. Linked migration, on the other hand, is much less responsive to these factors, and not at all responsive to destination unemployment and welfare levels. Separate tests of male and female models suggest a great contrast between independent and linked migration for females. It is concluded that the understanding of Black migration must take into account a variety of factors beyond traditional labor market conditions, including links to the destination and individual housing circumstances.

    Notes: The traditional shift-share model measures the combined effects of output growth and productivity change on employment. A region with above average employment growth either has a favorable industry mix or enjoys a competitive advantage over other regions. To separate the effects of output and productivity, the shift-share model is extended to decompose the effects of changes in output and productivity on employment. This paper modifies the Rigby-Anderson extension by separating the contribution of labor and capital to productivity growth in the analysis of regional economic performance, and investigates twenty (two-digit SIC) manufacturing sectors in twelve states (six snowbelt, six sunbelt states) to assess whether observed changes in employment were due to changes in output or to productivity.

    Notes: Given the dramatic divergence of postwar performance across the developing world despite almost half a century of accumulated technical expertise in the advice offered by the academic and donor communities, it has become increasingly clear that a study of differential development patterns over time requires an analysis of not only what happened but also why it happened. This paper seeks to bridge this gap by attempting to endogenize policy choice in different developing country settings in order to elucidate why similar policy advice is so often differently received. It is my basic premise that a country's initial conditions—its natural resource endowment, organic nationalism, and ability to attract foreign capital—explain why some LDCs pursue a relatively linear path toward “modem-growth” organizational characteristics, while others exhibit policy oscillations en route. A theoretical framework is developed to trace such causal relationships as they play themselves out in a political economy context over time. The policy responses to external shocks of Mexico, the Philippines and Taiwan, three countries differing in terms of various dimensions of their initial conditions, are then examined, along with their consequent performance over the past thirty years in order to empirically test the hypotheses laid out in the framework.

    Notes: Previous studies employing the trade area analysis procedure of pull factors assume retail sectors are independent. However, interdependencies exist between and among retail sectors. Employing a multivariate Tobit procedure, the agglomerative aspects of retail trade can be captured. Results indictate that interdependencies exist between retail sectors and if these retail interdependencies are ignored, extension and outreach retail sector programs may prove to be ineffective.

    Notes: . Washington DC is the center of the nation's ninth largest metropolitan area (PMSA), home to 4.4 million people and 2.9 million employees in a web of 25 separate, autonomous municipalities spanning three states and the District of Columbia. As such, the region is a good place to analyze the pattern of suburbanization of producer service employment over the past 25 years. In addition to overall suburbanization, the metropolitan area has seen changes in the nature and role of its dominant economic force, the federal government. Direct federal employment has stagnated while federal contracts to private companies have soared. Producer service employment seemed to increase in importance in jurisdictions away from the region's core, simultaneous with increases in total employment, following increases in federal contracting, and independent of increases in federal employment. These trends have affected the growth of producer service employment across the metropolitan area, encouraging their suburbanization. By subjecting our initial models to sub-sector data and analysis of temporal trends in the coefficients, we uncover the uniqueness of legal services and additional evidence of suburbanization over time.

    Notes: :Differentials in U.S. state unemployment rates were persistent in the early 1990s. In addition, states with higher employment growth did not necessarily have the lowest unemployment rates. Thus, this paper examines the differentials in U.S. state unemployment rates from 1992 to 1994, decomposing them into the parts that were due to differences in recent employment growth, and those that were due to longer-term equilibrium factors. Also, using the shift-share model, employment growth differences are decomposed into an industry mix component and a competitiveness component. The decomposition of the 1992 to 1994 unemployment rate differentials is based on an econometric equation estimated using panel data from 1972 to 1991. Explanatory equilibrium factors included in the model are amenities, demographic characteristics, education, industry composition, labor mobility, and wage rates.

    The Regional Economic Impact of an Earthquake: Direct and Indirect Effects of Electricity Lifeline Disruptions (1997)

    Notes: This paper develops a methodology to estimate the regional economic impacts of electricity lifeline disruptions caused by a catastrophic earthquake. The methodology is based on specially designed input-output and linear programming models. A simulation of a major earthquake in the New Madrid Seismic Zone near Memphis, Tennessee, indicates the potential production loss over the recovery period could amount to as much as 7 percent of gross regional product. Reallocation of scarce electricity across sectors could reduce the impacts substantially. Additionally, an improved restoration pattern of electricity transmission substations across subareas could reduce losses even more.

    IMPLAN's Induced Effects Identified Through Multiplier Decomposition (1997)

    Notes: An analysis of regional multipliers is developed to reveal a structural flaw in how IMPLAN computes induced effects. This analysis reveals a fixed ratio across sectors between total and Type I employment multipliers, and that IMPLAN's “Type III” income multipliers are inversely related to the average wages in the direct and indirect sectors, and that “Type III” output multipliers are not affected by wages. A multiplier decomposition is developed that separates direct and indirect effects from the induced and further separates the induced impact into relative wage and regional income retention effects. The decomposition is useful in making comparisons among impact models.

    Contributions to Change in the Input-Output Model: The Search for Inverse Important Coefficients (1997)

    Notes: The relationship between changes in input-output structural coefficients and changes in the coefficients of the Leontief inverse is explained in a calculus-based framework. Knowledge of this relationship is essential for understanding how structural changes in one sector are transmitted across the economy, and is useful in forming updates to I-O tables given limited information. Empirically, we identify those coefficients likely to be the most important in causing inverse changes. We find that a selective and systematic updating procedure can lead to accurate updates without the need for complete data.

    Notes: A linear programming technique is used to measure total factor productivity change in the contiguous 48 states during the period 1977 to 1986. The technique allows the decomposition of productivity change into its constituent parts: technological change, changes in pure technical efficiency, and changes in scale economies. This decomposition is used to identify “innovative” states that are pushing out the production frontier as opposed to states that are primarily in the process of ‘catching-up.’

    The Agroindustry: A Neglected Aspect of the Location Theory of Manufacturing[The author] (1997)

    Notes: The agroindustry, that is, the industry of processing of agricultural products, plays an important role in the economy of a developing country. However, the location theory of manufacturing, as developed to date, is not applicable to this type of manufacturing. This paper attempts to examine this neglected aspect of the location theory of manufacturing. The model is built on a framework that is adopted by most previous studies on production location, except that one of the inputs is of the von Thunen type, that is, produced over space and initially sold to consumers in the town. The location behavior of an agroindustrial firm is systematically analyzed. Moreover, and more importantly, a comparison of an agroindustrial firm with its non-agroindustrial counterpart is presented, demonstrating clearly that in many respects, the location behaviors of these two categories of manufacturing are significant different.

    Migration Under Uncertainty: “Try Your Luck” or “Wait and See”[The author] (1997)

    Notes: Two types of uncertainty enter into the migration decision. First, current conditions in the destination region may not be observable. Second, the future evolution of conditions in both the origin and destination regions may be unknown. The first type of uncertainty can encourage speculative or “try your luck” migration, whereas uncertainty about the future acts in the opposite direction, deterring relocation. This paper presents a dynamic optimizing model of migration that incorporates both types of uncertainty. The model shows that in equilibrium uncertainty about the future is likely to be more important than uncertainty about present conditions in the decision to relocate.

    Notes: The paper shows an interregional trade model from which testable parameter restrictions for economic base theory, shown to be equivalent to the hypotheses of the Granger causality test, are derived. The results of the tests for three states, based on various bifurcation methods, suggest that economic base theory holds strongly for the crudest definition of the base, but not for others. The frequency analysis indicates a likely association between inherent cyclicalities in employment growth data and economic base theory. The regional multipliers and the timing of economic adjustments to exogenous shocks are also discussed.

    Notes: Regional analysts face a trade-off between timeliness and detail of commodity-industry data. The trade-off exists because the Bureau of Economic Analysis national aggregated annual update tables are published for years more recent than those for which the disaggregated benchmark accounts are available. Conventional wisdom holds that regionalization should precede aggregation, so a disaggregated foundation table is preferred to an aggregation of that same table. This paper shows that the Table Disaggregation and Adjustment (TDA) method of Jackson and Comer (1993) produces a better foundation for regionalization than an unadjusted benchmark, price-updated benchmark, or aggregated annual update table.

    Notes: This paper argues that policies to promote sustainable development which are formulated around attempts to objectify what is or is not sustainable in any specific circumstance are impotent and ill-conceived. Using the case of forest exploitation in the Malaysian state of Sarawak as an example, we suggest that progress in the theory and practice of sustainable development depends on a more adequate understanding of the causes of unsustainability. In Sarawak, development has involved a clear tendency towards increasingly profound forms of exploitation. A realist mode of explanation allows the mechanisms through which this tendency is expressed to be better understood. Identifying these mechanisms and understanding why and how increasingly exploitative and degrading practices are legitimated and empowered is crucial to understanding why and how unsustainable outcomes are produced and how they might be more effectively prevented.

    Notes: Nonparametric estimation procedures offer distinct advantages in modeling polycentric cities because they are flexible enough to account for functional form misspecification and incorrect subcenter sites. This paper presents locally weighted (LW) regression estimates of employment density in suburban Chicago. LW regression estimates are more accurate than OLS regression and capture the effects of missing variables. The results demonstrate that Chicago is indeed a polycentric city: although the traditional city center continues to affect employment density patterns in the suburbs, local peaks have developed around secondary employment centers.

    Notes: Ghosh's ‘supply-driven’ input-output model is a well-known alternative for Leontief's traditional ‘demand-driven’ input-output model. The Ghosh model calculates changes in gross sectoral outputs for exogenously specified changes in the sectoral inputs of primary factors. Typically, the model is interpreted so as to describe physical output changes as caused by changes in the physical inputs of primary factors. It has been convincingly argued, however, that this interpretation in terms of quantities is implausible. In the present paper it is shown that the supply-driven input-output model becomes plausible, once it is interpreted as a price model. That is, sectoral output values change due to price changes, which are caused by price changes for the primary inputs. Therefore the term Ghosh price model is adopted for the supply-driven model, whereas the demand-driven model is referred to as the Leontief quantity model. Dual to this Leontief quantity model is the standard Leontief price model. It is shown that the results obtained by the two price models are equivalent. Interpreting the supply-driven input-output model as a price model also allows for a meaningful interpretation of the inverse matrix in terms of multipliers. As the dual to the supply-driven (or Ghosh price) model the Ghosh quantity model is derived, which is equivalent to the demand-driven (or Leontief quantity) model.

    The Effect of Hedonic Migration Decisions and Region-Specific Amenities on Industrial Location: Could Silicon Valley Be in South Dakota? (1997)

    Notes: This paper analyzes the effect of hedonic migration decisions and regional amenities on industrial location. Labor-intensive firms bifurcate into companies that follow the workers completely to the most attractive places, and companies which engage in a trade-off between “following” and “compensation for disamenities.” In the latter case, regional amenities induce three distinct location patterns: (a) a concentration of firms where the level of amenities is rapidly changing, (b) a gradual change of industrial composition at intermediate locations, and (c) a concentration of specific industries at the periphery of high-amenity areas. These patterns explain some of the controversial empirical findings about regional amenities and migration.

    Notes: A new estimator links migration data to a random utility “voting with your feet” model to compare the relative living standards of pairs of regions. It is argued that this estimator has a firmer theoretical basis and uses migration information more efficiently than previous methods. An algorithm converts pairwise comparisons into rankings of the U.S. states for 1970, 1980, and 1990. The rankings indicate living standards were highest in the Northwest (1970, 1980) and the south Atlantic coast (1990). A nonparametric test suggests that the system was in disequilibrium in 1980 (probably due to energy price shocks), but near equilibrium in 1970 and 1990.

    Notes: In this article we extend the Carlino and Mills and Boarnet models of local development to test for the presence and direction of rural area linkages to urban areas in Functional Economic Areas (FEAs). In a sample of southern FEAs, we detect a mix of spillover and backwash effects from urban core and fringe areas to their rural hinterlands. Rural-area population and employment both grew faster than average between 1980 and 1990 if in an FEA with a pattern of urban decentralization.

    Metropolitan Income Inequality During the 1980s: The Impact of Urban Development, Industrial Mix, and Family Structure (1997)

    Notes: The empirical analysis in this paper explores the interurban variation in family income distribution. The results point to increasing urban development, rising female-headship, a widening educational distribution, and changes in the industrial and occupational mix as major contributing factors to rising inequality. However, the increase in the relative number of multiple worker families was a significant mitigating force to rising inequality. A decomposition of 1979 and 1989 cross-sectional models revealed that while changes in urban family and industrial characteristics have been sources of rising inequality, there has been significant structural change in the urban models acting to decrease inequality.

    Notes: Consider a two-stage non-cooperative Cournot game with location choice involving n≥ 2 firms each with several facilities. There are m≥ 2 spatially separated markets constituting the vertices of a network. Each firm first selects the locations of their facilities and then selects the quantities to supply to the markets to maximize its profit. There exists a Nash equilibrium in the quantities offered by each firm at the markets. Furthermore, when the demand in each market is sufficiently large, each firm chooses to locate its facilities only at vertices. With linear demand in each market, there exists a Nash location equilibrium.

    Israeli Settlement in Occupied Territories and its Impact on Housing Prices in Israel[*The autho] (1997)

    Notes: The real price of housing in Israel rose 132 percent from 1959 through 1988. This paper investigates the factors standing behind the temporal movement of the real price of housing. Special emphasise is given to the role of government policies that encouraged settlement in occupied territories. A static model of the housing market is formulated and estimated, which takes into account the interrelation between the housing market in Israel proper and the emerging market in the occupied territories. In addition to confirming the role of demand shifters in accounting for the increase in real housing prices, it is found that settlement in occupied territories was an important moderating factor. According to our estimates, settlement in occupied territories accounts for a moderation of 1 percent in the annual rate of price appreciation during the Labor government, and 2.4 percent during the Likud government. These figures are in line with our expectations in view of the different policies pursued by the rival governments.

    Notes: Since the early 1980s, there has been widespread debate over the impacts of rising levels of inward foreign direct investment (FDI) on the U.S. economy. A frequently noted, but little studied, issue within the debate is the impact of FDI on U.S. foreign trade, and particularly, on the foreign trade of U.S. regions. This study assesses the effects of FDI on the manufacturing export performance of U.S. states during the period from 1980 to 1991. Results indicate that increased levels of FDI are positively related to future improvements in state manufacturing export performance.

    Notes: In this paper we examine issues related to the regional images of spatial configurations and their performance in attracting resources that are expressed in terms of regional gross domestic product. The concepts of social and economic image efficiency are introduced and their dual relationship is acknowledged. A non-parametric frontier analysis methodology is proposed for assessing the two types of efficiency, based on the concept of data envelopment analysis. The method is applied to the twenty prefectures of Northern Greece on data that span the period 1981 to 1991.

    Notes: This paper examines the relationship between the residential development sequence and land price. Inherent in the dynamics of residential development is that the first consumers face the greatest risk since they do not know with certainty what the neighborhood characteristics will be; subsequent consumers have more information. The model predicts that land prices will rise over time relative to the market; developers offer the first consumers discounted land prices to compensate them for the first-mover disadvantage. The empirical evidence indicates that this is indeed the case.

    Gravity-Type Interactive Markov Models—Part II: Lyapunov Stability of Steady States (1997)

    Notes: In Part I of this paper (Smith and Hsieh, 1997) a programming formulation of steady states was developed for gravity-type interactive Markov chains in terms of their associated spatial-flow chains. These results are here applied to analyze the stability properties of interactive Markov chains. In particular, the objective function for this programming formulation is shown to constitute a Lyapunov function for an appropriately defined continuous-time version of spatial-flow chains. The Lyapunov stability properties of these spatial flows are then shown to yield corresponding stability properties for the continuous-time versions of interactive Markov chains. In particular, these processes always exhibit global convergence to steady states. Finally, it is shown that when steady states are unique, these convergence results are inherited by those interactive Markov chains that are ‘sufficiently close’ to their continuous-time versions.

    A Biproportional Filter to Compare Technical and Allocation Coefficient Variations (1997)

    Notes: In input-output analysis there are two alternate possibilities between Leontief's mechanism (fixed technical coefficients) and Ghosh's mechanism (fixed allocation coefficients). Testing the long-term consistency of these mechanisms entails comparing input-output matrices over time. This paper challenges the value of proportional filters (separate comparisons of column and row coefficients) and introduces the biproportional filter that allows simultaneous comparison of column and rows. An application is proposed using French input-output tables for 1980 and 1993. The stability of column coefficients cannot be taken for granted and, generally, for any sector, both row and column coefficients are found to change simultaneously.

    Notes: The sophistication of regional economic models has been demonstrated in numerous ways, most recently in the form of linking several modeling systems or in the expansion in the number of equations that can be manipulated successfully to produce impact analyses or forecasts. In this paper, an alternative perspective is employed. What do regional macro-level forecasts indicate about the process of structural change? A new methodology is illustrated that enables analysts to make forecasts of detailed structural change in the interindustry relations in an economy. Using a regional econometric input-output model developed for the Chicago metropolitan region, derived input-output tables are extracted for the period 1975–2016. These tables are then analyzed to determine the forecasted direction of structural changes for the region. The innovation illustrated here is based on a model that exploits the general equilibrium spirit of computable general equilibrium models through the adjustment of input coefficients to clear markets.

    Notes: An important class of interactive Markov migration models is characterized by gravity-type transition kernels, in which migration flows in each time period are postulated to vary inversely with some symmetric measure of migration costs and directly with some population-dependent measure of attractiveness. This two-part study analyzes the uniqueness and stability properties of steady states for such processes. In this first part, it is shown that a flow version of the steady-state problem can be given a programming formulation which permits global analysis of steady-state behavior. Within this programming framework, it is shown that when attractiveness is diminished by increased population congestion, the steady states for such processes are unique. The second part of the study will employ these results to analyze the stability properties of such steady states.

    Two-Way Migration in a Model with Identical Optimizing Agents (1997)

    Notes: The simplest migration models based on maximizing behavior assume movement toward more desirable locations, and therefore ignore the large portion of moves in the “wrong” direction. Based on a model with identical, utility-maximizing agents, the analysis below shows that changes in relative location attractiveness can cause many migrants to move against the dominant stream. Even when the population distribution is stable and variation in wages and prices across locations reflect compensating differentials, so locations are equally attractive, individuals choose to move between locations, spending parts of their lives in different locations. These results stem from the role of consumption opportunities in migration decisions, highlighting processes that have been largely ignored.

    Notes: This paper provides a description of the interdependencies in the production structure of the European Community (EC). For the measurement of these interdependencies, a new variant of the hypothetical extraction method is introduced. In contrast to earlier adaptations of this method, our approach allows for a natural distinction of the interdependencies into backward and forward linkages. The empirical results are based on the 1980 intercountry input-output table for seven countries of the EC. The nature of this type of data (viz. country-specific sectors) enables us to focus on the sectoral as well as the spatial dimension of the interdependencies.

The conclusion is that if the office and the plant are located separately, the value of the unit transmission cost of information on production significantly decreases.

    Notes: Zone pricing consists in determining simultaneously several delivered prices together with the zones where these prices apply. A model and algorithm are proposed to determine optimal facility locations, prices, tariff-zones, and market areas in order to maximize the firm's profit under zone pricing. The resulting nonlinear mixed-integer program is tackled by projecting the objective function on the price space, solving repeatedly uncapacitated facility location problems for fixed values of the prices. The implicit profit function so defined is optimized by branch-and-bound. Computational results are reported.

    Notes: In this study I focus on the impact of aggregate labor turnover and regional labor market conditions on gross in- and out-migration within the framework of a neoclassical flexible-wage (equilibrium) model and a fixed-wage (labor-market disequilibrium) model. Using annual panel data on internal gross migration flows in Sweden from 1970 to 1989, I find that regional differences in employment opportunities have the expected effects on migration. The empirical relationship between real wages and gross migration flows is found to be less congruent with theory implications, indicating that compensated regional income prospects are equalized primarily via the interaction between employment opportunities and gross migration flows. Cyclical changes in hirings are shown to have a robust and strongly significant positive scale effect on migration.

    An Empirical Evaluation of Profit Cycle Theory[The author] (1997)

    Notes: This study tests key hypotheses of Markusen's profit cycle theory of regional growth by examining the recent time path of industrial development for eight U.S. sectors. The analysis uses annual data for 1954–1990 and incorporates the influence of national economic trends and random effects in identifying stages of the profit cycle. Based upon those stages, the hypothesized changes in the behavior of other aspects of the growth cycle are assessed in simple statistical models. The results of the empirical tests are mixed. Employment follows a general pattern of early rapid growth followed by slow growth and eventually decline, but the pattern is not symmetric. The value-added curves are similarly asymmetric, and some even contradict the expected monotonicity of the growth and decline process. The lack of spatial dispersion is probably the most striking result of the study. The stability over time of the employment percentage in top states is inconsistent with the spatial dispersion implications of the profit cycle model.

    Notes: Sea foam and sea-surface films are pelagic habitats of common origin. This suggests a possible similarity between their microplanktonic assemblages and an a priori possibility to use foam samples in qualitative sea-surface film studies. The composition and abundance of microheterotrophs (nanoflagellates 〈5 μm and bacteria) in the Dalnezelenetskaya Inlet, Kola Peninsula, Barents Sea, in August 1987, was nearly identical in the foam and sea-surface film samples. In contrast, the enrichment of foam with autotrophs (nano- and microphytoplankton) exceeded by an order of magnitude that of sea-surface films, whereas their taxonomic compositions were virtually identical in both habitats. Elevated growth rates of phytoplankton in sea foam appear to be an ecological mechanism responsible for the enrichment.

    Carcass of a bowhead whale (Balaena mysticetus) found in the lateral moraine of the Jemelianovbreen glacier, eastern Svalbard (1997)

    Notes: An 8 m long carcass of a bowhead whale (Balaena mysticetus) melted out from remnant glacier ice in the lateral moraine of the Jemelianovbreen glacier in August 1996. Folded and sheared sediment bands in the ice suggest that the whale was incorporated during an advance of the glacier. The whale's longitudinal axis was oriented parallel to the direction of the ice-flow, with the thinnest posterior part dipping upflow. The posterior section was best preserved with muscles and blubber, although the entire skin surface was strongly decomposed and only a thick fibrous surface was left of the blubber. The abdominal wall was holed, most likely by marine organisms, and partly filled with a compacted mixture of well-sorted gravelly beach sediments and fat. the whale seems to have been incorporated into the glacier together with glaciomarine sediments and carried by the flowing ice to an altitude of ca. 15 m. Jemelianovbreen is a tidewater glacier with two known surge-episodes. The first and most extensive of these occurred ca. 1900 AD and reached ca. 7 km outside the present coast-line. Radiocarbon dating of a fragment of a caudal vertebra yielded 345 ± 40 14C years BP (1535-1660 cal. AD), suggesting that the whale lived some time during the last part of the cold period known as the Little Ice Age.

    Physiological characteristics of arctic tern Sterna paradisaea chicks in relation to egg volume (1997)

    Notes: The effect of egg volume on body mass, body composition and growth rate in arctic tern Sterna paradisaea chicks was studied at Ny-Ålesund, on Svalbard (78°55'N, 12°00'E), in order to investigate whether differences in egg size influence the physiological characteristics of the hatchlings. The relative content of yolk and albumen in eggs did not vary in proportion to egg volume. Hatchlings from large eggs had larger body masses than hatchlings from small eggs, with 71% of the overall variation in body mass accounted for egg volume. In newly-hatched chicks, water content, lean body and total lipid mass, as well as both leg and pectoral muscles, changed isometrically in proportion to egg volume. Hatchlings from large eggs, however, had disproportionately larger yolk sacs. The leg muscles of small chicks contained a lower proportion of water than the leg muscles of large chicks, indicating that the leg muscles of small hatchlings were functionally more mature. There was a weak, but significant, correlation between egg volume and growth rate. However, a residual analysis made to eliminate the effect of egg volume showed no correlation between hatchling body mass and growth rate. The results of the present study show that Arctic tern hatchlings from large eggs emerge with more yolk sac reserves, enabling them to better withstand periods of food-scarcity. During embryonic growth in small eggs, however, there seems to be a greater relative usage of yolk, resulting in a more developed leg musculature. This may partly compensate for the higher mass-specific heat loss in small hatchlings.

    Notes: Morphological structures and the occurrence of sea-ice sediments and ice-related algae at the ice floe-water column interface were studied by video observations in summer 1995. Recordings at twelve stations in the northern Laptev Sea and the adjacent Arctic Ocean showed large variations. On a medium-scale (metres), level ice and deformed floes as well as whole rafted and stacked floes were found. At the underside of floes, small-scale structures (centimetres such as bulges, depressions and holes were observed. The surface and sides of rafted floes sometimes had downward running grooves. Sediment inclusions occurred in diffuse or concentrated forms as well as in parallel streaks. Ice-related algae were visible as green areas at the underside of floes or as threads haniging into the water column. The distribution of sediments and algae was patchy. Some processes which might lead to the observed structures are suggested.

    Convergent flow of ice within the Astrolabe subglacial basin, Trre Adélie, East Antarctica: an hypothesis derived from nummerical modelling experiments (1997)

    Notes: The existence of a large subglacial lake beneath the antarctic Ice Sheet at Terre Adélie indicates the presence of basal ice at its pressure-melting temperature. A numerical model of the ice-sheet thermal regime is employed using the balance velocity of the ice sheet as an initial model input in order to calculate ice-sheet basal temperatures. However, the results from this model show the Terre Adélie area to be characterised by basal freezing. Heat in addition to that accounted for in the model is thus required at the ice-sheet base in order for pressure melting temperatures to be attained. The sources for such heat are (1) an enhanced geothermal heat flux and (2) an increase in frictional heating caused by the flow of ice. In this paper the latter possibility is expanded by hypothesising that subglacial topography induces convergent ice flow around Terre Adélie, causing enhanced basal ice velocities. Model experiments indicate that an increase in ice velocity (from 7 to at least 42 m yr−1) is required to raise the temperature of the basal ice to the pressure melting value. Increased ice velocity, and consequent frictional heat production due to convergent ice flow, may therefore be important in explaining the location of the subglacial lake in this region. These results allow the process of convergent ice flow within a contemporary ice sheet to be quantified. A verification (or otherwise) of the model results may be possible if ice surface velocity measurements from modem GPS methods are made.

    Notes: : Dense nonaqueous phase liquid (DNAPL) contaminated ground water has proven to be exceptionally difficult to remediate for both physical and chemical reasons. Since DNAPL's are denser than water, their movement is not governed by the direction of ground water flow as is generally the case for other ground water contaminants. Additionally, DNAPLs' interactions with aquifer solids through processes such as sorption tend to make the pollution linger or sometimes apparently disappear, only to return later. Unfortunately, pump-and-treat systems, the traditional way ground water contamination is addressed, have not been effective in cleaning DNAPL contaminated water. Other remediation technologies continue to be developed to address these problems. Policy changes will also be necessary to effectively address the difficulties associated with ground water remediation.

    Notes: : Drought has been a common feature in the United States during the past decade and has resulted in significant economic, social, and environmental impacts in virtually all parts of the nation. The purpose of this paper is two fold. First, the status of state drought planning is discussed to illustrate the significant increase in the number of states that have prepared response plans - from three states in 1982 to 27 in 1997. In addition, six states are now in various stages of plan development. Second, mitigative actions implemented by states in response to the series of severe drought years since 1986 are summarized. This information was obtained through a survey of states. The study concludes that states have made significant progress in addressing drought-related issues and concerns through the planning process. However, existing plans are still largely reactive in nature, treating drought in an emergency response mode. Mitigative actions adopted by states provide a unique archive that may be transferable to other states. Incorporating these actions into a more anticipatory, risk management approach to drought management will help states move away from the traditional crisis management approach.

    Notes: : We evaluate Washington's program of watershed analysis with respect to its goals as a cumulative effects assessment method, adaptive management, and a restoration tool. We also evaluate the program as a framework for implementing ecosystem management. A strength of the cumulative effects assessment method is in identifying and reducing the dominant, direct physical effects of forest land uses on salmonid habitat. This could be further strengthened by more emphasis on identifying problems that can be immediately remedied (e.g., identifying road erosion and landslide trigger sites; correctly locating fish-bearing waters, and identifying anthropogenic fish passage impediments). More effectively assessing and integrating changes from more than one type of input to streams, including all relevant inputs, and examining whether assumptions about those inputs are scientifically defensible, will also improve the cumulative effects assessment. Treating experimentation more formally, including placing a greater emphasis on monitoring the outcome of prescriptions, and determining the scientific defensibility and certainty level of prescriptions, will strengthen adaptive management. As a watershed restoration tool, the program needs defined goals and critical assessment methods (e.g., of historic productive capacity of aquatic habitat). To be consistent with ecosystem management, analyses need to be integrated into a larger spatial scale, and to include all relevant land uses and effects within that scale; objectives for various stream ‘inputs” need to be evaluated with respect to managing for ecological integrity and the ability to provide a measurable standard.

    ALTERED STREAMFLOW AND SEDIMENT ENTRAINMENT IN THE GUNNISON GORGE (1997)

    Notes: : The Gunnison River in the Gunnison Gorge is a canyon river where upstream dams regulate mainstem discharge but do not affect debris-flow sediment supply from tributaries entering below the reservoirs. Regulation since 1966 has altered flood frequency, streambed mobility, and fluvial geomorphology creating potential resource-management issues. The duration of moderate streamflows between 32.3 and 85.0 m3/s has increased threefold since 1966. This, along with flood-peak attenuation, has facilitated fine-sediment deposition and vegetation encroachment on stream banks. The Shields equation and on-site channel geometry and bed-material measurements were used to assess changes in sediment entrainment in four alluvial reaches. Sand and fine gravel are transported through riffle/pool reaches at most discharges, but the cobbles and boulders composing the streambed in many reaches now are infrequently entrained. Periodic debris flows add coarse sediment to rapids and can increase pool elevation and the streambed area affected by backwater and fine-sediment accumulation. Debris-flow supplied boulders accumulate on fans and in rapids and constrict the channel until reworked by larger floods. The response to streamflow-régime changes in the Gunnison Gorge could serve as an analog for alluvial reaches in other regulated canyon rivers.

    Notes: : Urbanization of a watershed degrades both the form and the function of the downstream aquatic system, causing changes that can occur rapidly and are very difficult to avoid or correct. A variety of physical data from lowland streams in western Washington displays the onset of readily observable aquatic-system degradation at a remarkably consistent level of development, typically about ten percent effective impervious area in a watershed. Even lower levels of urban development cause significant degradation in sensitive water bodies and a reduced, but less well quantified, level of function throughout the system as a whole. Unfortunately, established methods of mitigating the downstream impacts of urban development may have only limited effectiveness. Using continuous hydrologic modeling we have evaluated detention ponds designed by conventional event methodologies, and our findings demonstrate serious deficiencies in actual pond performance when compared to their design goals. Even with best efforts at mitigation, the sheer magnitude of development activities falling below a level of regulatory concern suggests that increased resource loss will invariably accompany development of a watershed. Without a better understanding of the critical processes that lead to degradation, some downstream aquatic-system damage is probably inevitable without limiting the extent of watershed development itself.

    Notes: : The spatial and temporal variability of dissolved oxygen (DO), biochemical oxygen demand (BOD), nitrate concentration and total coliform (TC) were investigated at nine sampling stations distributed along the main rivers of the Piracicaba River Basin, a 12,400 km2 catchment located in São Paulo State, one of the most developed regions of Brazil. Spatially, a downstream impoverishment of water quality conditions was observed, as seen by the decrease of DO, and increase of BOD, nitrate, and TC. These changes were probably caused by accumulating downstream discharge of domestic and industrial sewage. Temporal evaluation of 18 years of data showed that DO decreased with time for the majority of the sampling stations, while BOD, nitrate, and TC increased. A law, approved at the end of 1991, proposed a new water tax for river water extraction for industrial and agricultural use. The amount of this tax is determined according to the water quality of the extracted water. Therefore, the evaluation of the water quality status in this basin is a first step to help resources managers to determine the values for this tax.

    Notes: : We have developed an approach which examines ecosystem function and the potential effects of climatic shifts. The Lake McDonald watershed of Glacier National Park was the focus for two linked research activities: acquisition of baseline data on hydrologic, chemical and aquatic organism attributes that characterize this pristine northern rocky mountain watershed, and further developing the Regional Hydro-Ecosystem Simulation System (RHESSys), a collection of integrated models which collectively provide spatially explicit, mechanistically-derived outputs of ecosystem processes, including hydrologic outflow, soil moisture, and snow-pack water equivalence. In this unique setting field validation of RHESSys, outputs demonstrated that reasonable estimates of SWE and streamflow are being produced. RHESSys was used to predict annual stream discharge and temperature. The predictions, in conjunction with the field data, indicated that aquatic resources of the park may be significantly affected. Utilizing RHESSys to predict potential climate scenarios and response of other key ecosystem components can provide scientific insights as well as proactive guidelines for national park management.

    Notes: : The purpose of this article is to discuss the importance of uncertainty analysis in water quality modeling, with an emphasis on the identification of the correct model specification. A wetland phosphorus retention model is used as an example to illustrate the procedure of using a filtering technique for model structure identification. Model structure identification is typically done through model parameter estimation. However, due to many sources of error in both model parameterization and observed variables and data, error-in-variable is often a problem. Therefore, it is not appropriate to use the least squares method for parameter estimation. Two alternative methods for parameter estimation are presented. The first method is the maximum likelihood estimator, which assumes independence of the observed response variable values. In anticipating the possible violation of the independence assumption, a second method, which coupled a maximum likelihood estimator and Kalman filter model, was presented. Furthermore, a Monte Carlo simulation algorithm is presented as a preliminary method for judging whether the model structure is appropriate or not.

    MORPHOLOGIC RESPONSE OF SUBALPINE STREAMS TO TRANSBASIN FLOW DIVERSION (1997)

    Notes: : Flow has been diverted from Rocky Mountain streams for many years with little documentation of the impacts on physical form and biological function of the losing stream system. This study addresses whether differences in form can be detected in subalpine step-pool, plane bed, or pool-riffle channels and linked to changes in flow regime from diversion. Total annual discharge was reduced between 20 and 60 percent and average annual peak flow was reduced up to 45 percent in the subalpine systems assessed; channels were diverted between 20 and 100 years. Expected impacts include reduced conveyance and changes in vegetation growth patterns because formerly active surfaces are colonized by riparian species, effectuating shrinking channel capacity. In this study, reduced channel width is used as an indicator of morphologic response. Observed reductions in width, ranging from 35 to 50 percent at some sites, resulted not only from vegetation invasion of stable surfaces but also from the development of an inset beside former cut banks. This observation, however, was restricted to wider pool-riffle channels with gravel bars. Outside of these areas, morphologic changes were either subtle or absent. The absence of widespread response is attributed primarily to periodic “flooding” of the diverted channel. During wetter-than-average years when excess water is available, minimal flow is diverted and the hydrograph resembles a free-flowing regime. The release of high flow to the natural channel potentially offsets changes in form incurred during “dry” periods. The stable nature and structure of subalpine channels also contributes to the absence of reduced capacity.

    Notes: : Predictive models for nitrate in four streams in the Bull Run Watershed in the Cascade Mountains of Oregon were developed from a record of 17 years of nitrate samples. The models are time series regression models written in terms of Log(nitrate load). The independent variables are logarithm of 14-day mean daily stream discharge, current day's precipitation, logarithm of the previous day's precipitation, total precipitation for the previous seven days, a hydrograph position variable that indicates rising or falling limb, and average maximum air temperature for the preceding 14 days. The models describe annual cycle and seasonable trends and variations in nitrate load, but are unable to describe large day to day variations like those associated with hydrograph peaks.

    Notes: : Habitat unit classification can be a useful descriptive tool in hierarchical stream classification. However, a critical evaluation reveals that it is applied inappropriately when used to quantify aquatic habitat or channel morphology in an attempt to monitor the response of individual streams to human activities. First, due to the subjectivity of the measure, observer bias seriously compromises repeatability, precision, and transferability of the method. Second, important geomorphic and ecological changes in stream habitats are not always manifested as changes in habitat-unit frequency or characteristics. Third, classification data are nominal, which can intrinsically limit their amenability to statistical analysis. Finally, using the frequency of specific habitat unit types (e.g., pool/riffle ratio or percent pool) as a response variable for stream monitoring commonly leads to the establishment of management thresholds or targets for habitat-unit types. This, in turn, encourages managers to focus on direct manipulation or replacement of habitat structures while neglecting long-term maintenance or re-establishment of habitat-forming biophysical processes. Stream habitat managers and scientists should only use habitat unit classification to descriptively stratify in-stream conditions. They should not use habitat unit classification as a means of quantifying and monitoring aquatic habitat and channel morphology. Monitoring must instead focus on direct, repeatable, cost-efficient, and quantitative measures of selected physical, chemical, and biological components and processes spanning several scales of resolution.

    Notes: : In order to assess the effects. of silvicultural and drainage practices on water quality it is necessary to understand their impacts on hydrology. The hydrology of a 340 ha artificially drained forested watershed in eastern North Carolina was studied for a five-year period (1988–92). Effects of soils, beds and changes in vegetation on water table depth, evapotranspiration (ET) and drainage outflows were analyzed. Total annual outflows from the watershed varied from 29 percent of the rainfall during the driest year (1990) when mostly mature trees were present to as much as 53 percent during a year of normal rainfall (1992) after about a third of the trees were harvested. Annual ET from the watershed, calculated as the difference between annual rainfall and outflow, varied from 76 percent of the calculated potential ET for a dry year to as much as 99 percent for a wet year. Average estimated ET was 58 percent of rainfall for the five-year period. Flow rates per unit area were consistently higher from a smaller harvested block (Block B - 82 ha) of the watershed than from the watershed as a whole. This is likely due to time lags, as drainage water flows through the ditch-canal network in the watershed, and to timber harvesting of the smaller gaged block.

    Notes: : Proxy climate data for the last 500 years collected from the archives of counties in the Yangtze River Delta, China, were analyzed to identify the occurrence of extreme climate events, the pattern of such occurrences and their relationships to El Nino-Southern Oscillation (ENSO). This study identified the cycle periods of 3.5, 5.5 and 8.6 years for floods and 18.5 years for droughts in the Yangtze River Delta during the last 500 year period and noted 16 regional (delta wide) extreme events during this period. All regional (delta wide) extreme climate events during the last 500 years (since 1500 A.D.) occurred either during or immediately after ENSO (5–6 year) activities. Hydrological impacts of extreme climate events, such as major floods and droughts, on human systems have long been among the foremost concerns of the Pacific Rim countries. Management of systems increasingly dominated by humans, such as Asian delta regions, should, therefore, include consideration of major climate variability, ENSO events and the extent of climate changes, as well as consideration of the trends associated with human growth and institutional changes.

    Notes: : In an effort to adopt more holistic ecosystem approaches to resource assessment and management, many state and federal agencies have begun using watershed or ecoregion frameworks. Although few would question the need to make this move from dealing with problems and issues on a case by case or point-type basis to broader regional contexts, misunderstanding of each of the frameworks has resulted in inconsistency in their use and ultimate effectiveness. The focus of this paper is on the clarification of both frameworks. We stress that the issue is not whether to use watersheds (or basins or hydrologic units) or ecoregions for needs such as developing ecosystem management and non-point source pollution strategies or structuring water quality regulatory programs, but how to correctly use the frameworks together. Definitions, uses, and misuses of each of the frameworks are discussed as well as ways watersheds and ecoregions can be and have been used together effectively to meet resource management needs.

    EVALUATION OF FOREST PRACTICES PRESCRIPTIONS FROM WASHINGTON'S WATERSHED ANALYSIS PROGRAM (1997)

    Notes: : In Washington's watershed analysis program, scientific analysts identify watershed areas that are sensitive to forest practices. Land managers then develop watershed-specific rules or ‘prescriptions” that condition forestry activities in those sensitive areas. Prescriptions are intended to provide greater protection than existing, or 'standard,” rules where necessary to avoid cumulative effects on public aquatic resources (fish habitat and public works). To assess strengths and opportunities for improving Washington's watershed analysis, we evaluate prescriptions from 20 analyses conducted from 1993 to 1995. We ask: (1) Are prescriptions watershed specific, compared to the general, or 'standard” forest practices rules? (2) Are prescriptions scientifically sound? (3) What promotes or limits development of watershed-specific and scientifically sound prescriptions? We find: (1) Prescriptions tend to be similar to standard rules. One reason is that some components of the scientific assessment methodology incorporate approaches or assumptions from the standard rules, some of which are untested or unsupported. Another reason is that while other assessment methods are not patterned after the standard rules, resulting prescriptions do not necessarily integrate assessment information. (2) Many prescriptions lack a scientific rationale and are unproved in meeting their stated objectives. Despite the experimental nature of many prescriptions, they generally lack an evaluation component. (3) Washington's watershed analysis can be strengthened by: testing assumptions of some scientific assessment methods; basing prescriptions more rigorously on scientific assessment data and published scientific literature; and addressing uncertainty in whether prescriptions meet their objectives.

    REGIONAL HYDROLOGIC RESPONSE OF LOBLOLLY PINE TO AIR TEMPERATURE AND PRECIPITATION CHANGES (1997)

    Notes: : Large deviations in average annual air temperatures and total annual precipitation were observed across the southern United States during the last 50 years, and these fluctuations could become even larger during the next century. We used PnET-IIS, a monthly time-step forest process model that uses soil, vegetation, and climate inputs to assess the influence of changing climate on southern U.S. pine forest water use. After model predictions of historic drainage were validated, the potential influences of climate change on loblolly pine forest water use was assessed across the region using historic (1951 to 1984) monthly precipitation and air temperature which were modified by two general circulation models (GCMs). The GCMs predicted a 3.2°C to 7.2°C increase in average monthly air temperature, a -24 percent to + 31 percent change in monthly precipitation and a -1 percent to + 3 percent change in annual precipitation. As a comparison to the GCMs, a minimum climate change scenario using a constant 2°C increase in monthly air temperature and a 20 percent increase in monthly precipitation was run in conjunction with historic climate data. Predicted changes in forest water drainage were highly dependent on the GCM used. PnET-IIS predicted that along the northern range of loblolly pine, water yield would decrease with increasing leaf area, total evapotranspiration and soil water stress. However, across most of the southern U.S., PnET-IIS predicted decreased leaf area, total evapotranspiration, and soil water stress with an associated increase in water yield. Depending on the GCM and geographic location, predicted leaf area decreased to a point which would no longer sustain loblolly pine forests, and thus indicated a decrease in the southern most range of the species within the region. These results should be evaluated in relation to other changing environmental factors (i.e., CO2 and O3) which are not present in the current model.

    Notes: : Growing interest in agricultural irrigation in the Great Lakes basin presents an increasing competition to other uses of Great Lakes water. This paper, through a case study of the Mud Creek Irrigation District in the Saginaw Bay basin, Michigan, evaluates the potential hydrologic effects of withdrawing water for agricultural irrigation to the Great Lakes. Crop growth simulation models for corn, soybeans, dry beans, and the FAO Penman method were used to estimate the difference in evapotranspiration rates between irrigated and nonirrigated identical crops, based on climate, soil, and management data. The simulated results indicate that an additional 70–120 mm of water would be evapotranspirated during the growing season from irrigated crop fields as compared to nonirrigated identical plantings. Dependent upon the magnitude of irrigation expansion, an equivalent of about 1 to 5 mm of water from Lakes Huron-Michigan could be lost to the atmosphere. If agricultural irrigation further expands in the entire Great Lakes basin, the aggregated potential of water loss to the atmosphere through ET from all five Great Lakes would be even greater.

    Notes: : Gaging stations established in 1895 at Millville, West Virginia and in 1882 at Harpers Ferry, West Virginia record flows ranging from a maximum of 6,509 m3s-1 to a minimum of 2 m3s-1. Historical and botanical indicators were used to extend the systematic flood record of the Shenandoah River for a study reach approximately 7.5-km long. The long systematic record at the site provides a good opportunity to assess the accuracy of these sources of paleoflood information. Habitation of the area by settlers of European descent began in 1733, and historical flood records extend from 1748. Qualitative historical records from different sources were compared to yield the most complete flood history. The correlation between the various sources was extremely high. Botanical flood evidence preserved as adventitious sprouts, tree scars, and ring anomalies were documented in 37 trees. A flood chronology established from these data extended from 1896 to 1955. Botanical indicators provided an accurate, although incomplete, flood chronology. The ability to determine accurate flood stages from paleohydrologic indicators varied. Historical data yielded relatively accurate stages to within 1–2 m; only minimum values of flood stage could be obtained from botanical indicators. These results illustrate some of the strengths and weaknesses of paleohydrologic investigations in the eastern United States.

    Notes: : On May 19, 1993, a jury in the U.S. District Court for the Western District of New York found Southview Farm and Richard H. Popp guilty of violating the Clean Water Act on five occasions. The violations were the result of storm water runoff from a site used for disposal of dairy cattle manure from an unpermitted concentrated animal feeding operation. The presiding District Court judge later dismissed the jury verdict, and subsequently a U.S. Court of Appeals for the Second Circuit reversed the dismissal. The Court of Appeals concluded that the discharges were not exempt as agricultural storm water discharges, and that the manure spreaders involved were point sources. Because the use of animal manures in crop production activities will result, unavoidably, in the discharge of some pollutants to adjacent surface waters, a rational and universally applicable basis is needed to determine when such discharges are point versus nonpoint source. Current statutes and regulations do not delineate clearly such a boundary. To address this lack of specificity, I propose that application rates be based on recommended crop nutrient needs.

    Notes: : Integrated watershed ecosystem studies in National Parks or equivalent reserves suggest that effects of external processes on “protected” resources are subtle, chronic, and long-term. Ten years of data from National Park watersheds suggests that temperature and precipitation changes are linked to nitrogen levels in lakes and streams. We envision measurable biotic effects in these remote watersheds, if expected climate trends continue. The condition of natural resources within areas set aside for preservation are difficult to ascertain, but gaining this knowledge is the key to understanding ecosystem change and of processes operating among biotic and abiotic ecosystem components. There is increasing evidence that understanding the magnitude of variation within and between such processes can provide an early indication of environmental change and trends attributable to human-induced stress. The following four papers are case studies of how this concept has been implemented.* These long-term studies have expanded our knowledge of ecosystem response to natural and human-induced stress. The existence of these sites with a commitment to gathering “long-term” ecosystem-level data permits research activities aimed at testing more important hypotheses on ecosystem processes and structure.

    Notes: : The National Park Service and the National Biological Service initiated research in Denali National Park and Preserve, a 2.4 million-hectare park in southcentral Alaska, to develop ecological monitoring protocols for national parks in the Arctic/Subarctic biogeographic area. We are focusing pilot studies on design questions, on scaling issues and regionalization, ecosystem structure and function, indicator selection and evaluation, and monitoring technologies. Rock Creek, a headwater stream near Denali headquarters, is the ecological scale for initial testing of a watershed ecosystem approach. Our conceptual model embraces principles of the hydrological cycle, hypotheses of global climate change, and biological interactions of organisms occupying intermediate, but poorly studied, positions in Alaskan food webs. The field approach includes hydrological and depositional considerations and a suite of integrated measures linking key aquatic and terrestrial biota, environmental variables, or defined ecological processes, in order to establish ecological conditions and detect, track, and understand mechanisms of environmental change. Our sampling activities include corresponding measures of physical, chemical, and biological attributes in four Rock Creek habitats believed characteristic of the greater system diversity of Denali. This paper gives examples of data sets, program integration and scaling, and research needs.

    Notes: : Human induced long-term changes in precipitation and stream chemistry have been observed in eastern North America and Europe, but few long-term studies have been conducted in coastal western North America. The objectives of this research were to determine: (1) time trends in precipitation and stream chemistry in a pristine old-growth forest watershed, and (2) seasonal patterns in precipitation and stream chemistry. It was conducted in 58 ha West Twin Creek Watershed, Hoh River Valley, Olympic National Park, Washington from 1984 to 1993. Vegetation consists of old-growth forest, with western hemlock, Douglas-fir, western redcedar, Pacific silver fir, and Sitka spruce being the dominant tree species. Annual precipitation varied from 2336 to 4518 mm during the study period with the majority of the rain falling between October and May. Chemistry of precipitation was strongly dominated by oceanic influences with Na and Cl being the dominant ions. The chemistry of the stream was influenced by bedrock weathering and was dominated by Ca, HCO3, and SO4 and was not strongly related to precipitation chemistry. The pH of precipitation averaged 5.3 over time and ranged from 4.3 to 7.1, while the stream pH averaged 7.5 and ranged from 5.5 to 9.0. There were few long-term trends in the chemical constituents of bulk precipitation or stream water with the exception of a slight decrease in NO3 in precipitation and an increase of SO4 in stream water. A trend of decreasing concentrations of Ca, Mg and Na in precipitation also occurred. There were no significant seasonal patterns in precipitation although the highest SO4 concentrations usually occurred in late spring and summer perhaps due marine algal activity. Strong seasonal trends occurred in concentrations of HCO3, SO4, Ca, Mg, and Na in stream water resulting from weathering and stream flow patterns, with highest ion concentrations occurring just before the onset of the rainy season. Pulses of NO3 in the stream were observed during fall and early winter resulting from the release of NO3 which had accumulated in soils or sediments.

    Notes: : Pollutants in urban storm water runoff, a significant and increasing fraction of pollutants in some waters of the U.S., originate from multiple activities. The industrial sector, one source category, is subject to federal and state-level storm water pollution prevention regulations, primarily General NPDES Permits that rely heavily on facility operators to identify themselves and develop appropriate site-specific pollutant controls. Degree of compliance is not readily determined and enforcement is inhibited because no publicly-available inventories contain data necessary to comprehensively identify facilities required to comply. This research evaluates the first stage of compliance, facility self-identification, concentrating on the motor-vehicle, transportation industry category using data at three scales: statewide, regional, and local or watershed. Data for California statewide and for the Los Angeles region show about 8 percent to 15 percent of motor-vehicle transportation facilities have complied with first-stage requirements. However, facility-specific evaluation in one Los Angeles County watershed suggests less than 50 percent of facilities in the industry conduct industrial activities of the kind covered by regulations; others need not comply. Results show strong variation by industry category. Second-stage compliance, follow-up reporting, is also evaluated for the Los Angeles region. About 17 percent to 34 percent of facilities completing first-stage requirements have also completed second-stage requirements.

    Notes: : The key events and the process that led to the creation of the World Water Council on World Water Day 1996 are reviewed and its characteristics summarized. The development of this new organization is discussed in the context of the major global trends in water and water-related issues, viz. growing water scarcity with its links to limits on food production and demographic patterns. In response to the need to find solutions to these pressing water issues, the development of a Technical Program based on the deliberations of the founding member organizations and a number of short-term activities have been outlined to demonstrate the evolution of the Council in this first year of its existence. Given the importance of complementarity between the Council and the Global Water Partnership, an attempt has been made to articulate the mutually-reinforcing roles of the two organizations.

    Notes: : Water quality variables were sampled over 109 weeks along Coweeta Creek, a fifth-order stream located in the Appalachian mountains of western North Carolina. The purpose of this study was to observe any changes in water quality, over a range of flow conditions, with concomitant downstream changes in the mix of landuses. Variables sampled include pH, HCO32−, conductivity, NO3−−-N, NH4+-N, PO43−-P, C1−-, Na, K, Ca2+, Mg2+, SO42−, 5iO2, turbidity, temperature, dissolved oxygen, total and fecal coliform, and focal streptococcus. Landcover/landuse was interpreted from 1:20,000 aerial photographs and entered in a GIS, along with information on total and paved road length, building location and density, catchment boundaries, hydrography, and slope. Linear regressions were performed to relate basin and near-stream landscape variables to water quality.Consistent, cumulative, downstream changes in water quality variables were observed along Coweeta Creek, concomitant with downstream, human-caused changes in landuse. Furthermore, larger downstream changes in water quality variables were observed during stormflow when compared to baseflow, suggesting cumulative impacts due to landscape alteration under study conditions were much greater during storm events. Although most water quality regulations, legislation, and sampling are promulgated for baseflow conditions, this work indicates they should also consider the cumulative impacts of physical, chemical, and biological water quality during stormflow.
