Notes: X-ray diffraction (XRD) patterns from nominally β-SiC specimens often differ from those expected for the cubic crystal structure. These differences include the presence of additional peaks, enhanced background intensities, peak broadening, changes in relative peak heights, and shifts in peak positions. It has long been recognized that they are due to the presence of stacking faults, and models relating the experimental observations to stacking fault population have continued to evolve. The presence and relative magnitude of these features vary among different β-SiC specimens. In this work, computer simulations were used to show that the variations are closely related to differences in the type and spatial distribution of stacking faults in each specimen. In these simulations, stacking sequences were generated using a selectively activated 1-D Ising model with a Boltzmann-type probability function for specifying errors, which allows a wide variety of fault configurations to be generated. Direct correlations between different features in the XRD data to the underlying fault population are demonstrated, which are discussed in this paper. It is also shown that this computer model is general, in the sense that many of the models presented in prior work can be interpreted as limiting cases of it.

Notes: The UK government recently introduced legislation to treat the qualifying distribution on a repurchase of shares in the same way as ‘foreign income dividends’. This paper examines and criticises this reform from two perspectives. First, there is no underlying rationale for such an approach. Second, the legislation moves the tax system away from simplification. A better approach would have been to remove the advance corporation tax (ACT) charge on a repurchase.

Notes: This paper examines the impact of the UK housing benefit system on the financial returns to employment of people in local authority or Housing Association accommodation. It outlines the current structure of housing benefit and examines its effects on the returns to employment using data from the Family Expenditure Survey. It analyses the consequences of a number of reforms to the current system — lowering social rents, increasing the levels of housing benefit received in work and restricting the amount of rent covered by housing benefit payments. This analysis highlights the trade-offs involved in various strategies available for restructuring the present system. JEL classification: H3, H4, J3.

Notes: The United Nations' newly completed study of purchasing power parities covering 34 countries varied in region, income level, and form of economic organization shows the systematic differences between the usual view of the structure of the world economy arising out of international comparisons based upon foreign exchange rate conversions and the structure one sees when actual prices are available.The real per capita GDP of developing countries is understated relative to developed countries when exchange rates are used in converting countries' national income accounts to a common currency, with the degree of understatement for any two countries being inversely related to the per capita income difference between them. The reason for this is that relative prices in the non-traded goods sector are lower relative to traded goods prices in low income countries. The systematic pattern observed in the 1975 data of the 34 countries has been extrapolated over time and space to get estimates of GDP for other years and countries.In the absence of detailed price data, the real shares of final expenditures devoted to particular components of the total can only be estimated as the proportion of own currency total expenditure devoted to the components. The observed differences in the pattern of prices of poor countries relative to rich for different components makes this clearly wrong for international comparisons, and in systematic ways. For example, (i) the relative price of services compared with commodities in poor countries is lower than in rich; so the apparent tendency of the share of services to rise as a country's income rises disappears when real quantities are considered; similarly, (ii) the relative price of capital goods is greater in poor countries compared with rich ones, so the difference in investment ratios out of GDP between rich and poor countries is understated.

Notes: The change in goods and services available in a national economy brought about by the shifting of external price relationships is referred to as the terms of trade effects. This paper reviews the various methods which have been devised since the war to define and quantify such effects on the Gross National Product. The statistical annex shows that, as far as OECD countries are concerned, the differences between the various measures are not significant. Whereas the effects from terms of trade represented, on average, less than one half of one percent of the GNP of OECD countries during the 1960's the percentage has increased substantially since 1973, due most importantly to the increase in the oil price; by 1977 (on a 1970 price basis), it had reached 5 percent of GNP in Japan and up to 6 percent in Italy. On the other hand, the extreme case of Saudi Arabia where various formulas generate effects amounting to between one half and the whole of GNP, indicates that the measurement of terms of trade effects by various methods may give different results.

Notes: The concern with income distribution has always mainly existed because of a concern with individuals' economic welfare. In recent years, the question has arisen whether the distribution of annual income—the distribution most often studied—is the best proxy for the distribution of economic welfare. Other measures, such as lifetime income, have been proposed instead.The paper starts with a discussion of how to define and measure the distribution of lifetime income. By using a simulation model, which partly consists of estimated functions and partly of tax functions taken directly from tax laws, distributions of lifetime income, variously defined, are then constructed. These distributions are compared with each other, and with distributions of annual income. The simulations indicate that the distribution of lifetime income is considerably less unequal than the distribution of annual income. Whether inheritances are included or not seems to be of no importance for the inequality of lifetime income. If, on the other hand, we include the value of leisure time in lifetime income, inequality increases by about 10–15 percent. Distributions of income after tax have Gini coefficients which are approximately 25 percent less than the Ginis for the before-tax distributions. We thus find that the picture of inequality we get is very much dependent on which income concept we use.

Notes: The charitable giving of UK households has changed considerably over the past 20 years. In particular, the proportion of households giving to charity fell by 5 percentage points between 1974 and 1993–94. An increase in the average size of donations meant that total voluntary income increased in real terms over the period, but, since 1988, voluntary income has stagnated. The greatest falls in the number of givers are among households in their twenties and thirties. There are clear trends in giving across households by age and income, with younger and poorer households tending to give less. But not only are today's younger households less likely to give than today's middle-aged households; they are also less likely to give than today's middle-aged households did when they were young. These generational trends in giving do not bode well for levels of voluntary income in the future. JEL classification: D12. D16.

Notes: The tax system in the UK has developed through numerous ad hoc changes to its structure. This has resulted in a situation where the way in which the tax system is described does not readily correspond to the marginal rate schedule actually faced by taxpayers. This paper outlines the connection between the formal description of the tax system and the marginal rate schedule faced by taxpayers. It argues that the operation of the tax system would be greatly clarified if it were described explicitly in terms of its marginal rate schedule.

Notes: This paper considers some of the economic impacts that demographic change may have in developed economies over the next fifty years. I focus on the role that financial markets might play in economies where the pressure on government-run unfunded pension systems is likely to rise. The role of unfunded schemes is considered in a world where financial markets are incomplete and important types of risk cannot easily be offset by trading. How demographic shifts might affect labour productivity, asset prices and aggregate output is investigated using a simulation model of an economy where population structure is changing.

Notes: The ‘Green Book’ and the recent EGRUP report support exchequer cost per job as a key input in the ex-ante appraisal of individual applications for Regional Selective Assistance (RSA) and the ex-post evaluation of the RSA scheme as a whole. In this paper, following a recommendation in the House of Commons Trade and Industry Committee's report on regional policy, the merits of an alternative, explicitly cost-benefit, framework are outlined. This approach incorporates the administration and compliance costs of the subsidy, costs at present ignored in RSA evaluation studies. An optimal ex-ante appraisal rule is developed. This takes the form of a cost-per-job ceiling, and a representative value is calculated for this figure. JEL classification: H20.

Notes: This paper discusses the history of the French development of satellite accounts during the late 1960s and 1970s, noting the circumstances that led to the initiation of work in this area and describing the types of problem encountered. It then goes on to draw, on the basis of the French experiment, more general conclusions and to present a proposed accounting framework. The final section considers the concept of social expenditure, but concludes that, at least for the present, it is not possible to construct a useful global concept.

Notes: The economy of Liberia is one in which, in spite of past satisfactory growth performance, a high level of income inequality persists. In 1977, for instance, a mere 2 percent of the people accounted for some 33 percent of nation-wide wage income. These people live disproportionately in Montserrado County in which the capital city is located. While each of the other counties are largely rural and poor, each has far lower intra-county inequality than wealthy Montserrado.Intersectoral location of the income-earner, average income levels and the extent of access to human capital formation opportunities are some characteristics of the economy that have been found to explain significant portions of intercounty variations in the levels of household income concentration. Income inequality is reduced with increases in the extent of agricultural activity as the share of the top income group falls and that of the bottom group rises. The reverse happens with growing urban-area activity. Higher income concentration occurs with rising per capita incomes as the top group's income share rises and the bottom income group's share falls. While this appears to be an instance of the Kuznet U-shaped hypothesis, here there are no definite signs of a possible reversal any time soon. The levels of access to educational facilities move inversely with the level of inequality, with expanding elementary facilities benefiting the poorer people at the expense of the wealthy while the reverse happens in the case of expanding secondary educational facilities.

Notes: This article describes what happens to income distribution during intensive changes in gross domestic product due to external market conditions. It deals specifically with an open market petroleum-based economy, Trinidad and Tobago, and reviews changes in national product and income levels and the income distribution pattern over the twenty year period 1957–76.The paper argues that during the period characterized by subperiods of steady growth and rapid growth in GDP (the latter associated with the petroleum price rise), income inequality increased between 1957 and 1972 and then decreased in the post petroleum-price-rise period of rapid growth 1973–76. While the effect of intensive changes in national product did trickle down to the lower income groups, income inequality in 1975–76 was greater than that existing in 1957–58. An examination of the spatial, occupational and temporal aspect of the distribution pattern points towards the elimination of structural dualism in the economy as the surest path towards greater income equality in Trinidad and Tobago.

Notes: The debate on how to deal with changes of relative prices in national accounts has, so far, remained inconclusive, especially with regard to the question of how to measure gains from changes of terms of trade. Keeping the experiences of the 1970s in mind (i.e. substantial changes of relative prices sparked off by increased oil prices), this state of affairs is not considered tenable.On this background, the paper takes up the old debate on how to deflate figures of domestic product, total as well as by industries. It tries to argue that deflated figures should be presented not only as real product figures by industries (using the double deflation method), but also as real income figures, obtained by deflating the current-prices figures of a certain year by the same general price index. When this is done according to procedures spelled out in detail, gains/losses from changes of the terms of trade in foreign trade will show up as an integral part of the framework.In the paper, special attention is given to the concept of industry terms of trade. On the basis of simplifying assumptions (which are, however, relaxed in the final part of the paper), it is shown how the ratio of real income divided by real product of a certain industry will be proportionate to the terms of trade of the industry concerned, when the latter concept is defined in the appropriate way. Furthermore, the sum of the industry gains/losses from changes of their terms of trade will be equal to the gain/loss of the economy taken as a whole from changes of the terms of trade in foreign trade.

Notes: In this paper, I investigate the validity of the Modigliani-Brumberg (M-B) model as an explanation of the variation of wealth holdings among households. The model as such, even with the inclusion of estimates of household lifetime earnings, explains only a minute portion of the variation in household wealth. Indeed, for certain groups such as non-white, rural residents, and the low educated, the coefficients of the regression model are insignificant. Moreover, when the top wealth holders are removed from the sample and when non-cash financial and business assets are eliminated from the household portfolios, the explanatory power of the M-B model increases markedly. Essentially, the validity of life-cycle wealth accumulation models must be restricted to the white, urban, educated middle classes and their accumulation of housing, durables, and cash. The rich have very different motives for saving and very different sources of saving, while the poor do not earn sufficient income over their lifetime to accumulate any non-negligible wealth.

Notes: This paper presents an analysis of the distributive impact of government expenditures in the United States. The analysis uses a household-level microdata file drawn from the 1970 U.S. Census of Population, with additional income and tax variables drawn from the Internal Revenue Service 1969—70 Tax File.The results are presented at both federal and local levels and include analyses of the distribution of individual benefits, as well as of overall taxes and net benefits. Since a microdata file was used, distributional effects are examined with respect not only to the “traditional” variables of income class and household size, but also with regard to the number of earners in the household and the sex and race of the household head.In a further paper in a subsequent issue of this review we will present the results of a similar analysis for the United Kingdom, and compare the results for the two countries.

Notes: In an important recent book dealing with the measurement of income inequality with particular reference to poverty,1 Prof. N. Kakwani derives several poverty indices, investigates the effect of negative income tax schemes with the help of those indices and gives a numerical illustration based on Malaysian data.The aim of this note is to point out some logical flaws in his argument. Some of the ideas expressed in the part of his book we are concerned with have been disseminated for some time now2 and referred to in subsequent literature;3 yet their shortcomings do not seem to have attracted anyone's attention. The introductory section gives a concise presentation of the relevant part of Kakwani's contribution. The next two sections deal with some problems with his approach.

Notes: The conceptual framework of the system specifies that societal resources are limited by two basic factors: the amount of available human time, and the stock of wealth inherited from the past. Wealth is defined very broadly to cover not only the conventional tangible capital assets familiar to economists, but also intangible human and other capital assets, stocks of organizational capital reflected by networks of social support systems (the family, the neighbourhood), stocks of environmental assets (the sun and air), and stocks of socio-political assets (security, freedom of choice). Human time covers market work, household production, leisure, and biological maintenance.Human time and capital stocks are used within households to produce a variety of tangible and intangible outputs, and these outputs in turn are used to produce a variety of satisfactions (utilities) or to augment stocks of capital, or both.The basic sources of well-being in the system are ultimately of two types: well-being is produced as a consequence of the intrinsic benefits from all activities engaged in by individuals, which is to say that people have preferences over the way they spend their time; secondly, people derive utilities from the existence of various stocks or states of society, and these satisfactions are independent of the way in which time is used. The satisfactions associated with flows of goods are subsumed by satisfactions derived from activities associated with those goods.The system contains a set of linkages among the various parts:inputs of goods and time are used to produce tangible household output, using the familiar notions of household production functions and constrained optimization; tangible household products, which are intermediate in the system, are used in conjunction with human time to produce direct satisfactions or to augment household capital stocks; both household (micro) and societal (macro) capital stocks are linked directly to psychological well-being; household activities are linked directly to flows of satisfactions, termed process benefits in the system; household preferences and values relating to policy variables are linked to public policies of various sorts, and policies modify the constraints and opportunities relevant for household decisions.The system also has dynamic linkages. Modifications of household or public stocks produce impacts on future flows of well-being; satisfactions from activities may adapt to the existence of constraints, hence changes in constraints can modify preferences and subsequently modify activities; and household behavior has a life-cycle dimension which is inherently dynamic.

Notes: Widely used summary measures of inequality or the idea of the “disappearing middle class” are potentially misleading. Divergences between evidence cited and conclusions drawn include failing to distinguish between the concepts of inequality and polarization, and using scalar “inequality” measures which are not consistent with rankings based on Lorenz curves. In addition, inappropriate claims about trends in inequality can arise from focusing on only a sub-population such as full-time male workers, and failing to account for sampling variability. These divergences are illustrated using Canadian data on labour incomes over the 1967 to 1994 period.

Notes: There are few sources of high-quality data on the dynamics of wealth accumulation. This paper uses newly available data from the 1983 89 panel of the Survey of Consumer Finances to examine household saving and portfolio change over the 1980s. Our main findings are as follows. First, median household wealth rose modestly over the period. Second, while overall wealth inequality increased, households in the top 1 percent of the wealth distribution in 1983 saw their share of total wealth decline, probably reflecting turnover among the very wealthy. Third, although age, income, and initial wealth had significant effects in regressions on household saving, a large part of the variation in saving was unexplained. Finally, there were clear life-cycle patterns in the portfolios of assets and liabilities held by households, with younger households acquiring homes, businesses and all types of debts, and older households divesting themselves of these assets and debts.

Notes: There is a growing awareness that it is important to understand patterns of family assistance; however, there is still a great deal of information about private transfers that is not known. This study begins to fill this void by presenting results from a new survey and integrating these findings with evidence from recent studies that use other new data sets. It is found that: (i) a large share of households participate in private transfer networks, (ii) a greater amount of financial assistance is provided to lower income family members, (iii) altruism does not fully explain transfer behavior, and (iv) people in their 20s and 30s receive more assistance than people of other ages, even the very old.

Notes: In this paper we analyze the determinants of material inputs into individual production activities as a function of their outputs. We use observations on a large cross-section of U.S. manufacturing plants from the Census of Manufactures, including those that make goods primary to other industries, to study differences in production techniques. We find that in most cases material requirements do not depend on whether goods are made as primary products or as secondary products. We thus elucidate support for the commodity technology model as a useful working hypothesis.

Notes: The 1993 SNA recommends chain volume indices over traditional fixed base indices as the principal measure of year-to-year volume movements in economic aggregates. Recognising, however, that “additive consistency” is important to many users, the SNA recommends that countries continue to compile traditional constant price data alongside the chain indices. In addition, the new international guidelines suggest a supply-use table framework for deriving indices. This paper considers how these demands can be met in practice. Particular attention is paid to deriving chain indices for industry value added within the same framework as that used for final demand components.

Notes: A large part of official economic data sets is produced with the help of assumed functional relations between variables. Constructing economic models on the basis of such model-generated data results in a “modeling on the basis of the results of modeling.” This common procedure can lead to consequences that seriously endanger the quality of empirical analyses. After discussing some of these dangerous consequences the authors explore the reasons behind this development. To avoid some of the most severe difficulties a “Charter for Compilation and Correct Handling of Economic Data” is proposed.

Notes: The paper shows that the Canadian System of National Accounts includes exhaustible resources but treats them as if they were produced goods. Thus, the claim that conventional accounts ignore the contribution of exhaustible natural resources is partly true. To fully account for exhaustible resources, we present an alternative national accounting framework that incorporates natural resource flows and stocks. The framework modifies the measure of the net domestic product by a factor that differs from the Hartwick-Solow-Weitzman rule and leads to different estimates of GDP, national wealth, and productivity growth. An application to the Canadian oil and gas industry shows order-of-magnitude effects.

Notes: This paper presents up-to-date estimates of the ability of non-resident fathers to pay child support. While no nationally representative data exist on the incomes of fathers, this issue has become more pertinent in recent years, as child support has become an important national issue. We find that fathers on average are able to pay nearly five times more in child support than they currently pay, and also that low income fathers can afford to pay substantially more than they actually pay. We also find that changes in nonmarital childbearing and the returns to education have had only minimal effects on trends in fathers' incomes.

Notes: In the United Kingdom there is a wide range of sources which make it possible to construct a series for components of personal wealth for the period 1920–56. The data are consistent with contemporary estimates produced for specific years in the 1920s and 1930s. They indicate that a stock-market boom and the effects of deflation and low interest rates on the nominal value of the national debt took the wealth/income ratio in the mid-1930s to a level not seen again until the housing boom of the 1980s.

Notes: The increased availability of cohort data and use of dynamic microsimulation models means that more attention is now being paid to longer term income concepts. Results are usually reported for only one income concept and a limited number of summary measures, and it is not clear whether results are influenced by the income concept used. This paper uses simulation methods to compare different approaches. For this purpose a very simple lifecycle earnings model was used to generate profiles of pre-tax incomes. Many comparisons were made using a flexible tax structure and four alternative income concepts. It was found that there was a substantial amount of agreement among the alternative concepts in making pairwise comparisons, with tentative support for the use of present values.

Notes: Using microdata from Household Budget Surveys of the Member States of the European Community, this paper examines the sensitivity of poverty statistics with respect to the choice of the equivalence scale. The results show that the ranking of the countries with respect to the overall poverty incidence is hardly affected when different equivalence scales are used. However, the composition of the poor population shows considerable changes when e.g. subjective equivalence scales are used instead of the OECD equivalence scale. The poverty incidence among specific household groups, such as single elderly and households with children, is particularly sensitive to the choice of the equivalence scale.

Notes: This paper discusses to what extent the economic growth in China in the 1980's has improved the economic well-being in urban regions of the provinces Sichuan and Liaoning and whether or not the economic growth has been attained at the cost of increased inequality. The study is based on individual household data from the State Statistical Bureau's Urban Household Survey during the 1986–90 period.

Notes: New GNP estimates in current and constant prices for the Belgian economy in the interwar period are presented. The series are conceptually and methodologically consistent with the post-World War Ii data and cover both the income and expenditure approaches. The new estimates differ considerably from the data that have been published before, casting new light on our present understanding of Belgian economic growth in the 1920s and 1930s.

Notes: While much of the evidence suggests that there was an increase in inequality in the U.S. during the 1980s, the reasons are less evident. Using the U.S. Consumer Expenditure Survey data, we find that the inequality of consumption-expenditures, as well as the inequality of other measures of resources, widened considerably during the 1980s. While previous studies suggest that increasing inequality is mainly due to increases in within group inequality, we show that by decomposing inequality by the interaction of family type and education almost three-fourths of the increase in inequality is accounted for by changes in inequality between groups and by shifts in the population.

Notes: This paper, using six waves of data (1984-89) from the United States Panel Study of Income Dynamics (PSID) and the German Socio-Economic Panel (GSOEP), compares economic well-being using single year income, multi-year income, and wealth as measures. We find inequality to be greater in the United States than in Germany regardless of the measure used. However, the relative degree of inequality varies across measures. When we disaggregate our data by age and gender categories, in general we find greater inequality in the United States, but wealth inequality among older Germans is greater than it is among older Americans.

Notes: National accounting concepts of value and income differ from their economic theoretic counterparts in two respects. Firstly, they are more precise in order to give concrete guidelines for measurement, e.g. with respect to the concept of capital formation and the treatment of taxes. Secondly, they are fundamentally different. Valuation in the national accounts is not forward-looking and not based on a notion of perfect competition. Similarly, concepts of income in the national accounts are not measures of net return to wealth or welfare and they do not intend to show income as a reward for some specific factors of production. The national accounts concepts of value and income are descriptive concepts that can only be well understood in view of the specific accounting framework to which they belong.

Notes: Can Eastern European families most severely impoverished during the transition to capitalism rely on private family safety nets? This question is likely critical for the transition's success, but little is known about family networks in Eastern Europe. We analyze newly available Polish household surveys, conducted both before and after Poland's economic transition, which measure private inter-household transfers. Such transfers are large and widespread in Poland, and in many ways appear to function like means-tested public transfers. They flow from high to low-income households and are targeted to young couples, families with many children and those experiencing illness. Private transfer patterns also suggest that they are responsive to liquidity constraints. Our results from 1987 data indicate that private transfers could fill a non-trivial portion of the income gap left by unemployment. However, we also find evidence from 1992 data suggesting that family networks weakened somewhat after the transition.

Notes: Using a nationwide household income survey, different types of income in the People's Republic of China at the end of the 1980s is analysed. The results show that various income types play quite different roles in rural and urban areas. Subsistence income makes up about half of the total income in rural China. Money income makes up about two-thirds of total income in urban China and is the major contributor to inequality in the entire country. In kind income, of which highly subsidized housing is the single most important category, is highly concentrated in urban areas and contributes greatly to inequality.

Notes: Poverty in Madagascar has increased between 1962 and 1980 both in the rural and urban areas based on a comparison of some poverty measures, but decreased based on others. However, it remains predominantly a rural phenomenon. Distributional inequality is the major determinant of the variation in rural poverty, while the changes in urban poverty are due to the lack of economic growth. Thus, the urban bias introduced in government policies in the mid-1970s was not justifiable on strictly poverty-reduction grounds. A reduction of sectoral disparities would have led to a significant reduction of aggregate poverty.

Notes: Models of aggregate productivity growth linked to sectoral models of production typically assume that all intermediate goods markets are perfectly competitive. An econometric analysis reveals that many intermediate goods markets exhibit transactions at prices quite different than marginal cost. Measures of productivity growth that ignore these market imperfections are biased. A measure of the actual magnitude of the bias that emerges under the assumption of equating price to marginal cost is constructed.

Notes: In this paper we examine household wealth and income in the Netherlands using data from the Socio Economic Panel (SEP) in the period 1987–89. We provide an evaluation of the quality of the data and some simple statistics which describe the behavior of wealth, saving, and income over the life cycle. We find there is substantial heterogeneity in the behavior of households, and wealth holdings vary substantially even among the same age group. By exploiting the panel feature of the SEP, we derive saving from first differencing wealth. We find that a sizeable fraction of households do not dissave when old and we find some evidence in favor of the bequest motive.

Notes: A taxonomy of multilateral methods is developed. All the main methods are classified within the taxonomy. It is then shown that methods in the same class share many of the same properties. Therefore the taxonomy should help practitioners to appreciate the wide range of alternative methods for making international comparisons, the relationships between methods, and the relative strengths and weaknesses of each method.

Notes: Little attention has been paid to the importance of consistency between the specifications of the income and the equivalence scales used in measuring economic well-being when noncash income is included in the definition of income. This article finds that inconsistency between the income and needs sides of a comparison can be important when some types of noncash income are included. An upward bias in the measured economic status of the aged when Medicare is included in income and an ordinary equivalence scale is used is presented as an example of the important effects of this consistency problem.

Notes: This paper provides two new data sets for comparisons of real income in OECD countries. The first set provides adjusted real series for GDP and its components from 1960 to 1993 based on OECD 1990 purchasing power parities. The second set uses OECD PPP of different benchmark years, and interpolates these applying national price indices. Comparisons between both alternatives, Penn World Tahle Mark 5 (PWT 5) and its new version (PWT 5.6), in terms of economic growth and convergence, reveal some remarkable differences. Moreover, there are wider differences concerning the relative countries' position in GDP per capita ranking. Estimations of convergence equations based on OECD data yield a better fit than those obtained using PWT data, although there are also some significant differences between PWT 5 and PWT 5.6. Nevertheless, a very positive result is that other parameters of interest in these equations are not affected by the use of these different data sources.

Notes: The output of the Swedish education sector is defined as the addition to lifetime incomes generated by the schooling system. Using cross-sectional information on wages, employment rates, working hours, school-participation and leisure time, all by years of schooling, we compute new output-based measures of the education sector. Measures that include and exclude leisure, and that are counted before and after taxes are computed for the years 1967, 1973, 1980 and 1990. Our most important conclusion is that the output-based measure differs so markedly from conventional input-based ones that a replacement of the latter with the former would change the picture of the overall performance of the Swedish economy over the period.

Notes: This paper estimates adult equivalence scales in the context of a nonlinear demand system using cross-section individual household data. It then evaluates the treatment of children under the tax allowance and child benefit systems on the basis of the estimated equivalence scales. The results suggest that a child benefit system allowing for economies of scale in the family is consistent with the cost of children implied by the notion of adult equivalence scale.

Notes: In the United States, the life-cycle relationship between initial Social Security contributions and subsequent benefits causes the effect of Social Security on income distribution to be overestimated in a single-period analytical framework. By separating the annuity from the redistributive aspects of Social Security we provide a life-cycle framework for measuring its net effect on redistribution. To this point in its history, we find all income classes have received positive net life-cycle income transfers and, in an absolute sense, upper-income groups have done at least as well as lower-income groups. This suggests a reason for the near-universal support of Social Security by past generations, as well as the controversy which now surrounds it. As it becomes apparent to younger cohorts of taxpayers that many of them will be net losers, it is inevitable that Social Security will be subject to the same controversy as other welfare programs which attempt to redistribute income.

Notes: Using data from the 1973 National Survey of Family Growth, the present study analyzes, for blacks and whites separately, the impact of female market activity on the inequality of the income distribution among households. The family life cycle is divided into three stages, according to the presence and age of children: (1) the interval between marriage and the birth of the first child, (2) the child-rearing interval, and (3) a final period which begins when all the children have reached school age. Using the coefficient of variation as an indicator of inequality, the empirical results show that in period 1, the contribution of white working wives has a large equalizing impact, while that of their black counterparts results in a slight increase in dispersion. In the child-rearing and post child-rearing stages, the labor supply of mothers decreases family income inequality by a small amount for both black and white households. A decomposition of the squared coefficient of variation of family income is presented to aid in the interpretation of these findings.

Notes: This paper examines the relationship between the cross-sectional and lifetime income distributions using a simple model of relative income mobility. It asks whether cross-sectional comparisons between countries can provide a good indication of lifetime inequality differences if income mobility is similar, and whether lifetime inequality increases by less than cross-sectional inequality if the latter increases as a result of higher mobility. Analytical and simulation methods are used to show that the answer to both questions is negative. Comparisons must allow for different types of mobility, the nature of the age-income profile and the age distribution in each country. JEL classification: D31.

Notes: There is an unresolved debate on the effect of tax-based savings incentives on government revenue. The conventional wisdom on tax-assisted saving plans (TASPs) holds that they reduce public savings, but may raise national savings by stimulating private savings. Feldstein (1995) has challenged the view that TASPs reduce government revenue. According to Feldstein, ‘some of the increase in personal saving raises the corporate capital stock, and the return on this additional capital raises corporate tax payments’. When the additional corporate income tax revenue is taken into account, ‘the revenue loss associated with IRAs [Individual Retirement Accounts] either is much smaller than has generally been estimated or is actually a revenue gain’.This paper extends Feldstein's analysis to incorporate international considerations, differences in tax structures and alternative values for key parameters. We show that the result presented by Feldstein represents a special case that does not lead to broad generalisations. We also show that, under most conditions, the tenets of conventional wisdom that TASPs reduce government revenue are likely to hold, but that the magnitude of the effect may not be large. Finally, we suggest that the focus of research on the savings effects of TASPs is justifiable in a closed economy, where domestic savings affect domestic investment, but is not useful for policy development in small open economies.

Notes: This paper illustrates recent trends in household consumption and personal savings in the UK and the US and discusses some theoretical models that can be used to interpret them. The trends in these two countries are interesting for several reasons. The decline in personal saving rates in the US during the 1980s is an unresolved puzzle. The corresponding variable in the UK has undergone large fluctuations, as have several other variables ranging from projected demographic trends to female labour supply. This paper stresses the need to analyse individual data to shed some light on these aggregate trends. It also stresses the need to have a sound structural model to interpret observed patterns in the data.The theoretical framework discussed throughout the paper is the life-cycle model, which views consumption and saving decisions as part of a dynamic optimisation process. The development of the model and the current research agenda and ways that it can be enriched with various degrees of sophistication are discussed. Particular attention is devoted to the discussion of the most recent developments. JEL classification Dl, E21.

Notes: The schedular system of income tax in the UK frequently comes under attack, not least in relation to the distinctions it draws between the tax treatment of the employed and the self-employed. However, on examination, it appears that non-schedular systems of taxation share both these distinctions and the difficulties that arise from them, albeit to varying degrees. The division between employed and self-employed is also problematic for social security systems. These difficulties are found, to a greater or lesser extent, in all the jurisdictions studied by the authors. It may be argued that all or some of the tax and social security differences are justified by fundamental economic and legal differences between the nature of employment and self-employment relationships. This may be true where the relationships compared are unambiguously, on the one hand, employment and, on the other, self-employment. However, there have always been non-standard relationships that combine characteristics of both these broad categories. This grey area appears to be increasing with changing work patterns. Consequently, the simple dichotomous system adopted by the UK tax and social security systems has come under pressure. This article considers the problems arising from this situation and some of the ideas that have been put forward to deal with them. JEL classification: H24, K34.

Notes: The possibility of an earned income tax credit, based on the US model, is currently high up the British political agenda. This paper examines the strengths and weaknesses of the current British system of in-work benefits, before reviewing the effectiveness of the US Earned Income Tax Credit (EITC) scheme. The British and US systems are then directly compared in terms of the net income delivered and the effective tax rate (net benefit deduction rate). Although the evidence in favour of a US-style EITC is weak, two possible variants are considered. The paper concludes that the only future for an EITC is probably as a partial scheme, linked to the amalgamation of in-work and out-of-work benefits, which removes wage subsidisation from the sphere of social security by means of a semi-individualised tax credit. Even so, the same goals could be achieved through the benefit system. JEL classification: H24, I38.

Notes: Pension systems in different countries vary widely in such aspects as the dependence of benefits on earlier labour income, the minimum permitted retirement age and limits on labour supply after retirement. This paper uses a simulation model of a rational, utility-maximising household facing the detailed pension provisions of eight European countries to study microeconomic distortions induced by the different rules and regulations. We examine in particular the impact on savings, labour supply, retirement age decisions and welfare. JEL classification: H55, J26, J65.

Notes: This paper analyses the windfall tax on the privatised utilities, introduced in the 1997 Budget. It describes the main arguments put forward for the tax and sets out the details of its scope, scale and method of implementation. The tax is examined against the guidelines of economic efficiency, fairness and administrative feasibility. A one-off tax based on past profits should be efficient, provided that the statement that it is one-off is credible. However, as a tax levied on companies, it does not directly tax the windfall gains that were made in the past by shareholders in the companies concerned. JEL classification: H25, L51, L98.

Notes: This paper analyses low income dynamics in Britain using the first four waves of the British Household Panel Survey. There is much low income turnover: although there is a small group of people who are persistently poor, more striking is the relatively large number of low income escapers and entrants from one year to the next. Simulations using estimated low income exit and re-entry rates demonstrate the importance of repeated low income spells for explaining a person's experience of low income over a given period. We also document the characteristics of low income stayers, escapers and entrants.

Notes: Although national and sector balance sheets have long been regarded as part of the national accounting framework, for a variety of reasons their compilation by official statisticians has been the exception rather than the rule. A programme of balance sheet work in the United Kingdom Central Statistical Office has recently been completed and the results published. The theoretical and practical problems arising in the course of this work are described and discussed. Summary results are given together with an interpretation of the main changes in the sectoral composition of national wealth between 1957 and 1975.

Notes: This paper presents an analysis of the distributive impact of public expenditures and taxes in the United Kingdom. The analysis uses household level microdata from the 1971 Family Expenditure Survey, with tax and expenditure aggregates drawn from the national accounts.The analysis is the first to allocate all taxes and public expenditures for the United Kingdom, and the results are compared to those from the more restricted analyses carried out by the U.K. Central Statistical Office. Results are presented for individual taxes and benefits as well as for overall net benefits and they describe distributional effects with respect to income class, household size, number of earners and housing tenure.A final section of the paper compares the results to those from a similar analysis for the United States which were reported in the previous issue of this review.

Notes: This paper considers the impact upon measures of corporate income of a number of concepts of the maintenance of the existing capital of an incorporated trading enterprise. A main distinction is drawn between the maintenance of all the assets employed in trading and the maintenance of the net assets attributable to the owners. Measures of income and of rates of return to capital depend on whether all the assets, or only the net assets attributable to the owners, are being considered. There are three sections of the paper after an introduction. Section 2 is conceptual and section 3 illustrates the concepts, with figures for U.K. manufacturing industry in 1975 to 1977, in which the figures in company balance sheets are adjusted from book values to estimated replacement cost, and estimates are made of depreciation at replacement cost and of the consumption of stock (inventories) at replacement cost. These figures follow the concept of maintaining physical assests. I have added calculations which extend the concept of capital maintenance to all operating or trading assets, including monetary working capital; and which then calculate the amounts necessary to maintain the assets attributable to the owners of a business. The three main methods are: to apply a gearing adjustment to abate the additional capital maintenance provisions for operating assets (which are realized revaluations by reference to their original cost); to take into income additionally the geared (or debt financed) portion of unrealized revaluations; and-what is conceptually much the same thing-to count as the charge for debt only real interest (which may be negative) rather than nominal interest. Section 4 considers some problems of aggregation, particularly the derivation of aggregates for the sectors of the economy, when based on figures for individual enterprises using the various approaches to capital maintenance.

Notes: Expanded measures of government output include imputed values of the services of government capital, uncompensated factor services of military draftees and jurors, and net revaluations, as well as the usually included compensation of employees. The government output is allocated to consumption, capital formation and product intermediate to other sectors, on the basis of its classification in ten broad functions: defense, space research, education, health, sanitation, transportation, parks and recreation, natural resources, welfare, and general administration. Final government product in 1976, including $116 billion in defense and $125 billion in education, amounted to $450.5 billion, which was 26.5 percent of the 1976 GNP. This final government product corresponded to the BEA measure of $191.6 billion.Total capital formation related to government is defined to include both government product which enters into capital formation in other sectors and government expenditures for its own capital accumulation. After a more rapid rate of growth in previous years, this total government capital formation in the United States in 1976 is found to exceed gross private domestic investment. A significant but only minor portion was found to be constituted by government expenditures for capital goods and change in government inventories. Investment in research and development, health and, particularly, education and training, were dominant components in capital formation related to government.

Notes: This paper focuses on the use of statistical matching in the estimation and analysis of the size distribution of family unit personal income. The paper begins with a brief discussion of data on the size distribution of income in the U.S. and their limitations. Several methods of improving or augmenting those data are described, and earlier examples of statistical matching for that purpose are mentioned. A brief summary of the types of statistical matching methods which have been used is also presented. Then a recent example of statistical matching carried out at the Office of Research and Statistics, Social Security Administration, is described, and the effects on the size distribution of adjusting and augmenting the initial data using the statistically matched data from that example are shown. Material relating to the accuracy of that statistical match is presented in the appendix.

Notes: This article presents the results of the first French efforts to assemble information on the assets and liabilities of the different economic agents. The estimates cover the five-year period 1972–76, with complete balance sheets for the end of 1971, 1972, and 1976. The experimental efforts showed that estimation was feasible. It was possible to bring together the varied, often dispersed, and rarely consistent existing information into an integrated body of aggregates adapted to macroeconomic analysis. The report stresses the importance of articulating the wealth accounts logically with the flow accounts, into a complete, closed, and consistent whole in which the theoretical objectives are well specified. It also points out the limitations of the approach, stemming primarily from the state of the basic statistics relating to wealth.

Notes: This paper is concerned with the distribution of wealth in Sweden in 1975 and its development during the period 1920–75. The paper is based on a large study on wealth undertaken for the Swedish Commission on Wage-Earners and Capital Formation. The first report from this study was presented in 1979 as a book in Swedish: Roland Spånt, Den svenska förmögenhetsfördelningens utveckling (The Development of the Distribution of Wealth in Sweden), SOU 1979:9. That first report will also be published in English. Prior to that the main results can be found in this paper.During 1980–81 we intend to publish specific reports on the distribution of shareholding, the effects of inflation, the development of the distribution of wealth 1975–78, the importance of pension rights etc.

Notes: Present national accounting conventions regarding the treatment of flows and stocks in the petroleum sector are considered to be unsatisfactory. But changes in reporting requirements for oil and gas producers open up possibilities for a more satisfactory treatment.In this article some aspects of the newly adopted requirements are presented and the possible uses of the additional information available for improving social accounts are discussed.

Notes: By both effect and example, tax policy in the United States has a huge impact on the rest of the world. This paper explores five features of the American tax system that seem, from a British and European perspective, to be both especially peculiar and potentially instructive. These are: the remarkably low overall level of taxation; the absence of a value added tax (or any other general national tax on consumption); the absence of any explicit interstate equalisation; the marginal subsidisation of low earnings under the Earned Income Tax Credit; and the fragmentation of power in policymaking, an important aspect of which is the role played by the Constitution.

Notes: In this paper, we investigate pay structures in the private and public sectors for West Germany. We commence by describing some basic features of the public sector. We use micro-data from the German Socio-Economic Panel for the years 1984–93 to analyse developments and differences in public and private sector wage distributions for both males and females. We break wages down into different education groups and age-groups, and use regressions to construct conditional wage differentials. Our results differ in many aspects from findings for the UK. For instance, we find that although mean wages are higher in the public sector for both males and females, conditional wages are higher in the private sector for all education groups for males, but higher in the public sector for females. JEL classification: J3.

Notes: This article, acknowledging the potentially important general attractions of the allowance for corporate equity (ACE), looks at some of its more specific implications.On corporate taxes, the article looks at questions about the implied revenue-neutral rate of corporation tax (and redistribution of the tax burden); the effects on cash flow of both government and companies; and what would become a crucially important charge on capital gains.On income tax, the article comments on the implications for self-employed earnings (and also, potentially, employees); for investment income and the logically accompanying EXPEP (extended personal equity plan); and therefore for inheritance tax.For international investment, the article notes that unless and until other countries adopt an ACE as the basis for harmonisation, the interaction of the ACE and existing taxes would not always be helpful for outward investment; and on some inward investment, if the most optimistic assumptions are not borne out, the effects could be rather bleak.

Notes: After a period of consultation, it has been decided that the Revenue should be empowered to issue legally-binding rulings in favour of taxpayers only where the relevant transaction has already taken place. This paper considers the reasons for having binding rulings, and argues that those reasons justify implementing pre- as well as post-transaction rulings. Additionally, it is contended that many of the more detailed aspects of the proposal warrant reconsideration in light of those underlying rationales. JEL classification: H20, K34.

Notes: This paper explores the implications of examining the effect of policy changes on individual incomes rather than household incomes. Conceptual problems arise from the treatment of collective resources and responsibilities, particularly children. These are dealt with in a manner that is transparent with the aim of establishing a practical method of analysing policy at the individual (and gender-specific) level. Two policy-related issues are examined in this framework: the impact of a minimum wage and the effect of introducing a minimum pension guarantee. In each case, the implications of choosing the individual as the income unit are examined and analysis of the issue by gender is presented. JEL classification: C81, D31, H55, J16.

Notes: This paper examines elements of British tax policy and discusses their implications for the US, where several recent proposals would mirror aspects of the British system. These include reducing filing requirements under the individual income tax, indexing capital gains for inflation, cutting mortgage interest deductions, enacting a value added tax, and integrating the corporate and personal income taxes. The paper also discusses implications of the poll tax for tax reform. Britain and America have made different choices involving equity, efficiency, simplicity and other goals. These choices offer the chance to help identify the impact of tax policy. JEL classification: H20.

Notes: In both Australia and the UK, programmes are under way to simplify tax legislation by rewriting it. This paper demonstrates that tax simplification is a complicated concept and concludes that sustainable improvement is unlikely to be achieved if reform is limited only to linguistic changes. Tax law is complicated because there are powerful pressures that tend to increase the complexity of modern tax systems and these should also be considered in any simplification programme. In addition, tax simplification may be promoted by the greater use of purposive legislation — that is, legislation drafted in terms of general principles rather than much more comprehensive legislation designed to deal with every likely possibility. The paper examines the progress of the Australian Tax Law Improvement Project and argues that what is needed is a strategy for tax simplification that is incorporated into the process of generating tax policy itself.

Notes: In this article the author describes workplace communities in British hotels and discusses the relationships between the workplace community and employees' subculture, family life and leisure patterns. He also discusses the role of the workplace community as an alternative to bureaucratic organisation and the consequences for people of working in a leisure context.

Notes: The currently high level of unemployment emphasises the importance (in policy terms) of the potential contribution of a self employment alternative. Here the author examines the available UK evidence on the degree of movement from unemployment to self employment, the factors influencing this movement and the role of labour market information and training.
