Notes: The Ordnance Survey makes extensive use of air survey in its mapping programmes at scales of 1 : 1250, 1 : 2500 and 1 : 10 000. A short history of the development of air survey within the Ordnance Survey leads into a description of current methods including the flying, processing and aerial triangulation tasks as well as the plotting of the maps by instrumental or graphical means.

Notes: A number of proposals have been put forward for the extraction of three dimensional data from a pair of electron microscope photographs taken from different angles. The methods used have, in general, been either point by point analyses or rather inconvenient. This paper shows that an existing photogrammetric plotter of topographic accuracy can, with very simple modification, be converted to give continuous plotting facilities from certain such micrographs.

Notes: The author reminisces upon a career of almost 40 years as a practising surveyor photogrammetrist, both as a Royal Engineer officer and as a director of a commercial survey organisation. The reminiscences include service with the Survey of India, war time operations in the Middle East and South East Asia Command, and commercial surveys of all types in developing countries. Professional service with international surveying and photogrammetric organisations is also mentioned, with particular reference to the fraternal aspects of international photogrammetry.

Notes: An increasing number of applications of photogrammetry are concerned with the analysis of models, constructed to simulate proposed or existing conditions in architecture and engineering. The paper draws attention to some of these projects and reports one example in detail.

Notes: The author describes the photogrammetric equipment in use by the Royal Commission on Historical Monuments (England), the methods used and the work that is being done in architectural recording. The difficulties and the possibilities of future architectural work in the United Kingdom are discussed and the achievements of some other countries in this field are reviewed.

Notes: Four papers were read during the first symposium to be held by the Photogrammetric Society, at the University of Birmingham on 3rd and 4th April. Major General R. LI. Brown examined the staff structure of the organisations engaged upon the photogrammetric production of maps in the United Kingdom. Mr. J. R. Hollwey outlined the syllabus for a new Higher National Certificate in photogrammetry during a session which was devoted to education and qualifications. Subsequently, Professor A. J. van der Weele explained the evolution of the courses at ITC. By way of contrast, Professor E. H. Thompson attempted a forecast of developments in photogrammetry during the next decade. The papers succeeded in initiating prolonged discussion among the 80 members who attended.

Notes: A method is described for determining wind vectors in the lower atmosphere from terrestrial stereophotography. The photographs were taken with specially adapted aerial cameras using the normal or parallel averted case with horizontal camera axes. The most favourable photographic registration was obtained on ORWO UT 16 colour reversal film. Photograph co-ordinates and horizontal parallaxes were measured and recorded on punched tape with the Zeiss (Jena) stecometer. Vector components, which were calculated from co-ordinate differences, and a statistical analysis were obtained by using an electronic computer.

Notes: The article discusses a general classification system applicable to digital ground models (D.G.M.) as used in highway design. Examples of the various categories are given, together with details of some advantages and disadvantages. The place of the D.G.M. in the highway design system is described in conjunction with traditional methods. The relationship between accuracy, density and economy of D.G.M. systems is examined. Finally an experiment is described which investigates the accuracy of various D.G.M. systems; it is being conducted by the Transport and Road Research Laboratory.

Notes: The use of aerial photography for hydrographic requirements is discussed, with particular reference to current circulation in an all water area. The paper examines the criteria and limitations imposed by an environment which is alien to normal topographic photogrammetry.

Notes: This paper proposes that salary structures and the development of salaries over time be considered within the framework of the distribution of income over time. In particular, it examines certain salary scales in the U.S. and the progressions of typical individuals’ salaries during the period 1948–1969, in comparison with the percentile distributions of household income in the same period, as reflected by the Current Population Survey of the Bureau of the Census.

Notes: This paper assesses the role of inventive and innovational activity in the growth process of Canada, a country which relies overwhelmingly, some 90 per cent, on the importation of technological advances and operational know-how from abroad. Canada has prospered under this arrangement but at a price. With technology came foreign capital, foreign management and substantial foreign control. To lessen Canada's dependence on foreign know-how, this country has embarked on an expanded R & D programme. But the pay-off from these efforts has been less than expected. To throw a light on the subject, the results of two new surveys are presented: one a sample survey of patents granted, the other an interview survey of large corporations. Questions examined include sources of know-how and technological advances, utilization of inventions and abandonment of innovations, R & D and innovations, domestic and foreign innovations, and the profitability of innovations. Aggregative assessment is supplemented by disaggregative analysis using cross-section and industry data.

Notes: The paper presents forecasting models for (1) the share of competitive imports in the total demand for a commodity group and (2) the level of demand for competitive imports of a commodity group. The two forecasting models are used, respectively, with (1) input-output models which incorporate market share parameters as one vector of coefficients and (2) input-output models which assume imports have been determined autonomously. It is shown that these two types of input-output models can be made workable by prefixing one or other of the import forecasting models to the input-output model. Tests are made of the forecasting ability of the combined models.

Notes: This article is an extension of an earlier article dealing with gains and losses from changes in the terms of trade. The object of the present article is to show how gains and losses in foreign trade are distributed among the branches of domestic industry. To this end, price changes for gross domestic product at factor cost in each of 25 branches of industry over the period 1949–1965, computed where possible by the double deflation method, are compared with the change over the same period in final demand—i.e., consumption plus gross investment.

Notes: This paper develops a method for estimating long-run trends in income growth from the data available on a country's currency stock. The method is applied to nineteenth-centry Brazil. The results indicate that contrary to earlier beliefs, the country as a whole probably experienced only moderate growth in per-capita income during the nineteenth century. The approach may also be useful for other countries where data shortages preclude estimates of national income by conventional methods.

Notes: This paper discusses the relevance of the conventional national accounts systems to the traditional African economy and concludes that they contribute little because they omit certain economic activities and fail to recognise the reciprocity between social and economic activities. Social accounting is thus more relevant. Lack of statistical data may make it necessary to conduct special surveys and in some cases a tribe or village or economic region may be a more useful accounting unit than a nation. A modified system of accounts is suggested, based on the frame work of the four consolidated accounts of the SNA. It provides linkages to many more nonmonetised activities. Other linkages would be provided through supporting tables emphasising social activities and transfers. A system of transactor accounts in matrix form is also suggested. In the case of communities smaller than the nation several external transactor sectors could be included. It is recognised that the problem of evaluation of social activities and a number of economic activities remains to be solved and it is concluded that “time spent” may be the only common unit or value to equate such activities.The final section deals with investment in human resources and proposes a balance sheet approach to indicative planning. This exercise would be related to demographic projections in several variants. Other factors to be analysed dynamically would be education and health status, public finance and, ultimately, distribution of income and wealth since it is noted that the process of monetisation is having an impact which may have important welfare implications.

Notes: In this paper the author adds some further empirical tests of his theory of income distribution. This theory (cf. this Review, Series 16, Number 3, September 1970, p. 221 ff) sees income distribution as the distribution of prices of production factors, especially labour, of different quality and prices as the effect of demand and supply factors. The quality of labour is represented only by the number of years of schooling. Its supply is described by the actual numbers of people having each of the possible years of schooling; this frequency distribution can be characterized by its average and by some measure of its dispersion or by one of its deciles (in particular the highest) expressed in terms of its median. The demand for the various qualities of labour can be supposed to be reflected by (i) total demand for commodities, but (ii) more accurately by the percentage of third-level educated people used in and weighted by the size of the four main sectors of production: agriculture, manufacturing, trade and transport, and other services. Extensive material collected and reworked by Professors B. R. Chiswick for the U.S.A. and Canada and T. P. Schultz and L. S. Burns with H. E. Frech III for the Netherlands is used in cross-section tests to explain variations in income distribution in the states of the U.S.A. and the provinces of Canada and the Netherlands. The results can be found in the tables. While further increase and smaller dispersion in years of schooling, according to some of the findings presented, would only moderately reduce the degree of inequality in the U.S.A. and Canada, more result seems to be possible according to other findings, including those for the Netherlands. In the latter category the second demand index mentioned above has been used. This paper is one of several devoted in various ways to the testing of the same theory.

Notes: Statistics for developing countries often are misunderstood and misinterpreted because the published data do not distinguish between the economically modern and the traditional sectors. The purpose of economic development is to move a nation from the traditional, or largely non-monetary, subsistence agriculture type of life, to the modern or money oriented and technologically developed type. Statistics of national accounts, the economically active (the working force), and other topics often fail to be useful for economic development purposes because they are presented for the totality of the country and do not show the modern-traditional sectors separately.In addition, data are often misinterpreted and used incorrectly because the development economists do not understand the nature of the data—how they were collected and what they really signify. This point is illustrated with the economically active statistics. Finally, a plea is made for more statistics and information about families.

Notes: This paper deals with some results of an extended investigation which was carried out by the German Institute of Economic Research, Berlin, and the Ifo-Institute, Munich, and financed by the Stiftung Volkswagenwerk. For 29 sectors of manufacturing Cobb-Douglas production functions have been calculated, based on quarterly figures 1958–1968 of value added, input of hours worked, input of utilized capital stock (net of scrappage), and of potential value added, potential labor input and total capital stock. The income distribution is used as production elasticities. For each of the 29 sectors 12 time series of quarterly indices of total factor input and technical change have been computed, using utilized data (variation 1-6) and capacity data (variation 7-12). Two different time series of α are used, taking quarterly interpolated data (variation 1, 3, 5, 7, 9, 11) and the geometric mean 1958–1968 (variation 2, 4, 6, 8, 10, 12). Moreover three different parameters of homogeneity are introduced, taking r= 1 (variation 1, 2, 7, 8), r= 1.1 (variation 3, 4, 9, 10) and r= 1.25 (variation 5, 6, 11, 12). Seven of the 29 sectors show a very high sensitivity of the rate of technical change due to the assumed r, six sectors a rather high sensitivity. Ten of the 29 sectors show a rather small sensitivity of technical change due to the assumed r, six sectors a very small or even negative sensitivity, i.e. an increasing r creates an increasing technical change. These results can be explained by taking account of the fact that total factor input in many branches increased very slowly or even decreased (labor input alone decreased in nearly all branches). A hierarchy of technical change has been calculated; this hierarchy is difficult to explain, because fast growing industries as well as industries with a small or a negative growth rate of output rank in both the leading and the last group of technical change. Very high rates of output result in high rates of technical change (chemicals, mineral oil refining, plastics manufactures), but some industries with a rather small growth of output (shipbuilding, fine ceramics, steel drawing, and cold rolling mills) show a high rate of technical change too.

Notes: An underlying theme in this paper is that the differences in approach in this area arise partly from the complexity of the phenomena in the real world being studied, the implications of this interrelated complexity for unbiassed and efficient estimates of the structural relations, and the problems of getting an adequate number of observations of the required form.Two distinct approaches have been used in the study of marginal and total factor productivity. One approach is to use the factor shares in national income as weights to combine the individual factor inputs to make an index of total factor input, and to use a factor's relative share to measure its marginal contribution. The second approach is to estimate the production relation from the data being used, and derive the marginal contribution of the productive factors to output from the estimated relation. The longest parts of the paper review the procedures followed to cope with the main problems in the real world, and the strengths and limitations in the two approaches. The discussion emphasizes the issues for the economy as a whole, and touches only briefly on the issues in disaggregation.Three major themes are emphasized in the conclusions to the paper. One is that many of the problems, the differences in view, and the controversies grow out of the range of interrelated issues in practical applications. A second major theme is that most of the attempts to solve particular issues by those using the factor shares approach are rather similar to those followed by researchers estimating the production relations directly. A third theme is to encourage more studies that will look at the interconnections between production relations and income distribution, from the points of view of both economic theory (and its predictions about the relevance to concrete applications) and statistical estimation.

Notes: This note attempts to shed some light on the relationship between the total factor productivity derived from national income accounts and the total input productivity based upon input-output accounts, especially on a sectoral basis. Since there has been no positive evidence to support a constancy between changes in net and gross output in individual industries, the formulation of a measure of sectoral input productivity change by using the formula of the Divisia index based on input-output accounts may be valuable in examining possible biases which are associated with a common notion of the total factor productivity. An operational definition of sectoral input productivity change and its relation to sectoral total factor productivity are discussed in the present note, in addition to its empirical application to the Japanese data.

Notes: This paper summarizes the results of several studies on total factor productivity of twenty-five countries over the period 1950–1965. Some methodological issues which underlie the derivation and calculation of the familiar partial and total factor productivity indices are discussed. Though evidence on labor productivity for a large number of countries is presented and discussed, the main thrust of the discussion is in terms of the determinants of total factor productivity. The quantitative and qualitative contributions of labor and capital to growth of income are assessed with special attention to the contrasting patterns of these contributions among developed and developing economies. The problems of acceleration and retardation of the growth rate of some economies are considered and possible explanations are offered. Variations in the magnitude and sectoral distribution of the growth rates in several countries over this period are examined. Finally, areas for further research in comparative economic growth are suggested.

Notes: This paper discusses the estimation of the CES Production Function with Hicks-neutral technical change, and gives the results of an empirical study based on time series data (quarterly values) for sixteen industrial sectors in the Federal Republic of Germany (including West-Berlin), 1958–1968. The validity of the basic assumptions of the production model used in this investigation—neutrality of technical change and perfect competition—is tested by estimation of alternative specifications of the equations of this model. For this purpose two different methods of estimation were used.

Notes: Developing countries which typically have import surpluses and inflationary pressures because of insufficient savings are prone to use indirect taxes on imports (Tm) and subsidization of exports (Sx) in order to prevent deterioration of the balance of trade. If these substitutes for devaluation are included in the net indirect tax component of product at current market prices (Ym) the import surplus is likely to be understated, and Ym upward biased. This distortion will be avoided if imports and exports are measured at effective exchange rates (ER), that is, at official rates (OR) plus Tm and Sx respectively, and if (Tm - Sx) is deducted from the net indirect tax component of Ym. Only in this manner become imports and exports consistent with the other uses and resources at market prices and can be articulated with them. At base-year prices the volume index of product at OR diverges from that of ER to the degree that the composition of imports and exports in regard to tax and subsidy rates computed ad valorem significantly changes.Such a case is similar to that of the price indexes of imports and exports moving in diverging proportions: the trade balance at base-year prices will differ from that at current prices. The resulting discrepancies in national accounts have led to proposals of deflating, for example, exports by the price index of imports. Suchlike approaches are incompatible with the principle of national accounting that prices are supposed already to measure substitution values. Deflating exports by import prices means reintroducing substitution values, as does, for example, deflation of incomes by a consumer price index. Correspondingly, since the trade balance at ER conceptually expresses the value of imports at domestic market prices as compared to the corresponding domestic market value of exports, and if at ER the trade balance diverges from that at OR, the former balance has an important meaning (as has the trade balance at base-year prices as compared to that at current prices) and the resulting discrepancy between the two measures should not be removed merely for the sake of accounting smoothness.In contrast to the market price approach, the measurement of product at base-year factor cost is indifferent to the measurement of the trade balance at ER and at OR.It is, therefore, proposed in countries in which part of import taxation and export subsidization substitutes for devaluation, to record imports and exports in the national accounts at effective exchange rates, and to correct the net indirect tax component of product correspondingly. Imports and exports at official exchange rates should be shown within the balance of payments, and the latter separately as a memorandum item.

Notes: Changes in many output determinants contribute to growth. An analysis of the sources of growth is an allocation of changes in output among these determinants. Total factor input and output per unit of input condense all determinants into two groupings. Misinterpretation of results is common because authors presenting either detailed or summary results often provide no complete or precise description of their classification of determinants, and readers ignore even the information provided. The classification suggested in this paper is detailed enough to bring out points at which description is required but often overlooked. Some effects of alternative estimating procedures on classification are described.The relative usefulness and practicality of possible alternative classifications also need consideration and discussion. This paper is concerned with general purpose classifications, appropriate for analysis of actual series measuring a country's total output, that are suitable for present use but will also accommodate useful detail that may later become feasible. A desirable classification will so specify determinants that (1) they both unite cause with effect and correspond to the economist's method of analysis so that his set of tools can be brought to bear; (2) they do not contribute to growth if they do not change; and (3) they conform as well as possible to practical possibility of estimation. Among several points considered fundamental are that the complete contributions of advances in knowledge and of resource reallocation each appear as an entity. They should not be dispersed among inputs or other determinants. It is less clear whether economies of scale should be a separate determinant or their contribution be dispersed.

Notes: This paper describes the methods used by the Office of Business Economics, U.S. Department of Commerce, in creating a microdata file for use in estimating the size distribution of income. It explains the techniques of statistical matching involved in merging microdata files from various sources to correct and supplement income estimates in the original field survey (The Current Population Survey) and to incorporate additional information that can be used to estimate items and types of income not contained in the original file.

Notes: The quantity index comparing the per capita consumption of one country vis-à-vis the other often gives widely different figures, depending on which country's prices are used as “weights”. In this paper, this gap between two quantity indexes is divided into a substitution effect and an income effect by assuming common tastes between nations. For this division, we estimate the points of over-compensated variation and under-compensated variation in income from Gilbert and Kravis’data.The results of our estimation show that the income effect is smaller than the substitution effect. But the sign of the income effect indicates that this effect is generally in the same direction as the difference between two quantity indexes. Translated into the Bortkiewicz covariance, this means that the income elasticities are inversely related to the relative prices; the higher the income elasticity of a good, the lower is its price in the high income country relative to the low income country.Since we only approximate the points of exactly compensated variation in income, we cannot estimate “true” quantity indexes. However, our result implies that the two indexes in Gilbert and Kravis’data do form the upper and lower boundaries to the true index-numbers.

Notes: There is increased interest in flow of funds analysis due to the greater role assigned to money and to financial processes in the economic reforms now being implemented in Eastern Europe. After presenting a history of financial flows analysis, the paper describes data sources, and sectoring procedures. The efforts of particular countries are then reviewed and compared.

Notes: This paper describes and examines three particular features of the official national income tables recently published by the Fiji Government. The need of development planners for a comprehensive set of national accounts incorporating detailed information relating to central government current expenditure, the operations of the private business sector, and the rural household economy has assumed special importance. The uses and limitations to the information contained under these specific headings is discussed and throughout an emphasis is placed on the need for the adoption of consistent and systematic methods of collection and estimation procedures to facilitate planning and decision making. As aids to more detailed interpretation and analysis, the features described are considered to be of general interest to other developing countries.

Notes: This paper discusses the conceptual framework in which regional economic accounts in the United States are viewed and the functions which those accounts serve. It points out that the major differences between regional and national accounts relate to factor returns to capital. First, returns to capital are extremely difficult, if not impossible, to measure meaningfully on a geographic basis. Secondly, because the capital market in the United States is a reasonably perfect one geographically, the return to capital that originates in a given region has little significance as either a stimulant or a constraint to production in that region.In terms of the functions of regional accounts, the point is made that whereas national economic accounts can aid economic decision-making in three general areas of policyallocation, distribution and stabilization—with perhaps greatest emphasis now placed on the last of these, regional accounts are most useful in matters relating to allocation and distribution.Information needed for the use of regional accounts in decision-making with regard to allocation and distribution problems is examined. Against these needs are placed an inventory of regional accounts which are available in the Regional Economics Division, Office of Business Economics. The available accounts are found to fall considerably short of those needed for allocation decisions. In contrast, regional accounts as presently constituted have much to offer as tools for analyzing the problems of regional economic distribution, although here too, much additional information is needed.

Notes: Conventional measures of national product make no pretence of including everything that affects welfare. As increasing attention is being paid to environmental pollution, the problem of incorporating certain non-economic variables into the analysis of well-being becomes more relevant. The object of this note is to show how a difference in “needs” for, and hence expenditures on, anti-pollutants, which will show up in conventional national accounts comparisons as differences in “tastes”, should be converted into differences in real income.

Notes: The CMEA standard of statistical information provides a system of national wealth indicators. The paper deals with certain time series published in these countries and in the CMEA Statistical Yearbook as the components of that system. Special attention is paid to the USSR interbranch balance of 30 types of fixed assets cross-classified by 105 branches of economy. This balance is analogous to the input-output table technique in the western literature. On the basis of this balance the Soviet statisticians furnish coefficients of direct and total requirements in fixed assets for each branch. Such coefficients are usually called capital ratios or capital coefficients. In the USSR they are calculated together with the coefficients of direct and total requirements of labour for the same industries, and they supplement input-output tables. The scheme of the fixed assets balance and the matrix for the calculation of these coefficients are described in the paper together with some numerical illustrations of actual coefficients reached in the calculations.

Notes: The purpose of this paper is to investigate the sources of economic growth in Japan and to compare the results with those in the U.S. and Europe as studied by E. F. Denison. The method used by Denison is followed as far as possible. The character of this paper is of fact finding, and the interpretation of results or the originality of methodology is not dealt with here. The results may be summarized as follows.(1) Japan's growth rate is two times that of Europe and three times that of the United States.(2) The contributions of labor, capital, and the residual to economic growth are all higher for Japan than for the U.S. or Europe.(3) Factors which account for the higher contribution of labor to economic growth are (a) the higher rate of increase in employment, (b) less shortening of working hours, and (c) improved age and sex composition.(4) Factors which account for the higher contribution of capital to economic growth are a higher rate of increase in capital input and the high elasticity of production with respect to capital.(5) Other notable points include: (a) the contribution of education is lower for Japan; (b) the capital-labor ratio in Japan increased remarkably; (c) capital's share of national income is higher; and (d) 60% of Japan's economic growth is accounted for by the residual.

Notes: This paper analyses productivity growth in the Hungarian economy over the two decades between 1950 and 1970 with the aim of establishing what help can be provided in such analyses by the use of total factor productivity index numbers. After the introductory sections the paper deals first with the rates and factors of Hungarian productivity growth, and then with some methodological lessons of the investigation.

Notes: The paper discusses the relevance of input/output tables as a tool for economic analysis and planning in developing countries. It contends that this is so only to the extent that the input out-put tables enable consistency of production accounts to be verified while providing a suitable basis for macro projections at the same time. As a by-product, such input out put tables, the paper adds, also provide a convenient framework for estimating the needs for extensions and improvements in basic statistics.All these requirements, it is stated, can be fulfilled by a relatively aggregated format of an input/output table—which some of the developing countries are in a position to compile. However, the paper states, it is feared that the case for input/output analysis is not based on these requirements. The main force of arguments is in fact based on the uses of input/output tables for more detailed sectoral analysis and projections. The current state of basic statistics on some key sectors, it is stated, is not sufficiently sound to yield an end-product which is reliable. In the case of sectors where this is so the input/output analysis is not relevant either because of concentration of production in a relatively few establishments or because of limited amount of inter-sectoral interaction. It is further felt that if such arguments were to be accepted by developing countries the result would be a distorted disposition of statistical resources. Immediate needs of the developing countries require concentration of effort in development of more reliable and relevant series on basic statistics.

Notes: At present two systems of measurement of national product are in practice, one as defined in the UN System of National Accounts (SNA) and the other termed the Material Product System (MPS) or National Balances for the Economy. In the present paper, an expanded system of accounts integrating the national balances within the framework of a simplified SNA has been suggested. The accounts suggested are mainly the two sets of (i) Supply, Disposition and Domestic Production of goods and services and Consumption Expenditure of Budget and Mixed Organisations and the Population, and (ii) Income and Outlay and Capital Formation Accounts.The system is convenient not only for arriving at estimates by either of the two approaches, but is readily manageable. This set of accounts can, without any effort, be put in the form of a matrix leading to its ultimate integration with either the UN System of National Accounts or a modified system of national balances.The system gives not only the integrated system of SNA and national balances, but also a coded list of transactors and transactions within the economy. This coded list can be used as the first set of information for the creation of the economic data bank for the Integrated Statistical Information System.

Notes: Historical data for the manufacturing industry in the United States and United Kingdom are quoted, showing in most cases divergences between Laspeyres and Paasche forms of the quantum index that are by no means negligible. When the Paasche index for two of the series is recalculated with quantity indicators for industries instead of for products, the divergence is greatly reduced, and when quantity indicators for industry groups are substituted it almost disappears. This raises some questions about the practices of econometricians and statisticians, which are discussed. In a mathematical appendix by E. R. Coleman it is suggested that the grouping effect referred to does not depend on the particular way in which the data are grouped in most quantum indexes.

Notes: Pour répondre aux besoins de la préparation du Plan, l'Institut National de la Statistique et des Etudes Economiques (I.N.S.E.E.) élabore des séries de comptes économiques régionaux ayant pour origine 1'année 1962. Ces comptes concernent les 21 régions de programme que distingue la planification française et sont élaborés de façon centraliseé selon des concepts étroitement dérivés de ceux du système français de comptabilité nationale. Toutefois la régionalisation de certains éléments des comptes nationaux qui paraissent peu utiles pour ľanalyse régionale n'est pas prévue. A l'inverse il a fallu apporter des solutions originales à divers problèmes qui ne se posent pas au niveau national, comme celui de la localisation des entreprises èétablissements multiples.Si le cadre comptable a été défini pour l'ensemble des comptes qu'on envisage de régionaliser, les premiers travaux ont porté sur les éléments qui pouvaient être évalués rapidement èľaide des statistiques immédiatement disponibles et qui présentaient le plus ďintérêt pour la re gionalisation du Plan. C'est ainsi qu'ont été réalisés en priorité les comptes des agents régionaux (collectivités locales, méanages, entreprises et éatablissements). Mais 1'equilobre régional des opéarations, qui nécessite de lourdes investigations stastiques, n'a fait l'objet que de travaux préliminaires.Parallèlement è l'elaboration des comptes régionaux, un modèle projections è moyen terme a été mis au point. Ce modèle, qui constitue régionalisation du modèle physicofinancier utilisé pour la planification nationale, concerne deux domaines: les collectivités locales et les ménages. La projection des comptes des collectivités locales perment ďétudier le financement des équipements collectifs; la projection des comptes des ménages fournit une mesure des dispartés régionales de revenus et de leur évolution. Les premières projections, préparées en 1970 pour ľannéae 1975 gardent, plus encore que les séaries de comptes réagionaux, un caractégre expéarimental.

Notes: The purpose of this paper is to explore the question of at what stage should Divisia index numbers be introduced–within the social accounting schema proper or in the explanatory stage following? Three major reasons are given to support the case that Divisia index numbers have no role to play in measurement, but should and do provide a powerful tool in the explanation of productivity change.

Notes: Overall balance between expected available resources and planned investment is not sufficient to ensure development with stability. Imbalances and inflationary pressures could develop as a result of inconsistencies between sector-wise investment structure and the sector-wise structure of saving. This means that the dichotomy between real and financial planning needs to be eliminated not only at the national level but at the sectoral levels as well, so that the sector-wise investment pattern is consistent with the emerging structure of saving and the flow-of-funds. This presents an analysis of the structure of saving and flow-of-funds in India, shows how it is actually used for the purpose of financial planning, and attempts to derive a formalized technique of financial planning. Analysis of the structure of saving in India during 1954–1955 to 1967–1968 indicates the importance of the household sector as the net lending sector to the borrowing sectors, the government and the private corporate sectors. On the basis of the feasible sectoral rates of growth in income and the past trends in sectoral saving-income ratios and household saving pattern with such modifications as are necessary in the light of expected changes in various policies, sector-wise saving structure and the pattern of household sector saving are projected for the Fourth Plan period (1969–1974).Then a flow-of-funds matrix is prepared to derive sector-wise investment estimates as are consistent with the estimated structure of saving and the likely changes in the lending policies of the financial institutions. A formalized technique of financial planning based on the Indian planning experience is presented in the last section of the paper.

Notes: This paper presents an attempt to examine the applicability of the relative income hypothesis (RIH) in terms of its various specifications proposed by Duesenberry, Duesenberry, Eckstein and Fromm (DEF), Davis and the authors (MD). Using the time series data for 1951 through 1968 the analysis has been carried out for Canada, Finland, Guatemala, Honduras, India, Japan, Philippines, Sweden, United Kingdom and the United States. It is found that RIH provides a fairly good representation of the consumption behaviour of all the countries included in the study. All specifications, however, do not perform equally well. DEF and Davis functions score the maximum points; MD comes at par with DEF in case of Finland, Guatemala, and India. The original Duesenberry specification performs very poorly. This leads us to conclude that the process of habit formation is continuous contrary to what is implied by Duesenberry's original specification and that consumption is a better indicator of the standard of living than income is. Estimates of the long-run marginal propensities to consume are essentially the same as those computed from the permanent income hypothesis by Singh and Drost [1970]. This lends support to the view that the two hypotheses have essentially the same long-run implications.

Notes: This paper contains some of the main results of an investigation into the use of educated manpower in Norwegian industries. An input-output model with labour inputs specified by education is presented. Per unit of final delivery, Norwegian exports in 1960 used relatively less labour, and less educated labour, but more capital (measured by depreciation) than the other categories of final demand. But when the use of labour is compared to the income created by the final deliveries, the differences are much smaller.

Notes: The objective of this paper is to reformulate the terms of trade effect within a framework of national accounts in constant prices. The issue has been discussed by Professor R. C. Geary, Dr. G. Stuvel and others. In what follows the author proposes a new formula for deflating the net factor income from abroad and the net lending to the rest of the world. It is shown that the terms of trade effect which follows from the formula be expressed as a synthesis of Geary's and Stuvel's approaches.The author also shows that a similar approach be applied to the construction of the sector production account in constant prices. By formulating an appropriate deflator which is right for deflating factor incomes he concludes that the terms of trade arising from changes in inputs prices relative to output price be closely associated with the term which expresses the effect of productivity changes.

Notes: The main objective of this paper is to explore and quantify the difference between two measures of comparative economic welfare: (a) the more or less conventional measure of per capita national income, and (b) the capitalized value of expected future income per capita. The paper begins with a brief summary of the argument in favor of the present value of expected future income per capita as a measure of economic welfare. This is followed by an examination of the empirical relationship of the ratio of the suggested alternative measure to per capita income and an analysis of the variables used to compute the present value of expected income per capita. The main conclusion drawn from the calculations is that very substantial differences occur in the measurement of relative economic well-being depending on which measure is used. A final section discusses the implications of this finding for international comparisons of economic welfare.

Notes: The official U.S. price deflators for investment goods continue to be based on defective methodology, despite frequent criticism in recent years. This paper contributes new price information, which is combined with the empirical results from other studies to yield a revised investment deflator for the 1954–1963 period which (a) rises much more slowly than the official index and (b) declines relative to a revised price index for consumption expenditures.

Notes: A number of official and Western estimates of China's national income for the period since 1949 are at present available. The official estimates are based on the Marxian production concept while the Western estimates are, in the main, based on the comprehensive production concept. The periods covered by the estimates vary; and even in cases where the periods covered are the same, the estimates vary in magnitude and, in most cases, in the implied rate of economic growth. Apart from differences arising from the different national income concepts and definitions employed in individual estimates, sources of discrepancies between series of estimates can be traced to the particular sets of primary data employed and also to the particular procedures followed in estimating the national income components. The present paper brings together the various estimates available to date and indicates for each, as far as possible, the basic production concept adopted, the particular national income aggregates estimated, the basic estimation approach employed, and the special procedures used for estimating some of the components of national income. Comparisons of the major series of estimates for the period 1952–1959 are made and the sources of discrepancies between the series are discussed. Finally, some problems are described which a researcher in the West has to contend with in working on China's national income accounting.

Notes: The purpose of this article is to present estimates of the Czechoslovak gross domestic product from 1913 through 1937 and to interpret these data in terms of certain crucial economic policy decisions. In the first part of the article, the major methods of estimation of the G.D.P. using a sector of origin approach are briefly discussed; a fuller description is presented in the appendix. The second part examines the major economic dilemmas facing the Czechoslovak government and the most important actual policy decisions. In order to provide quantitative perspective on the Czechoslovak successes and failures, national product and export series for all the Central European nations are also presented and briefly discussed.

Notes: An announced in the December 1971 issue of this Review, the Thirteenth General Conference of the International Association for Research in Income and Wealth will be held in Hungary in August of 1973. Persons interested in submitting papers to be considered for presentation in any of the sessions are reminded that they should communicate with the session organizer as soon as possible. A list of topics and session organizers will be found in the December 1971 issue of the Review.

Notes: The author describes the results of his current research designed to measure total investment, tangible and intangible, and the derived capital stocks for the U.S., 1929–1966. With respect to total investment, the estimates show a marked increase in its ratio to GNP. All of the increase occurs in the intangible component comprising R & D, education and training, health, and mobility. The increase was concentrated in the government sector, although households increased the proportion of disposable personal income devoted to total investment.Consistent with the relative investment trends, the stock of intangible capital grew considerably faster than the tangible stock. The growth of total capital stocks was somewhat less than that of GNP, however, in both current and constant prices. Thus, the rate of return on total capital rose somewhat over the period. Average rates of return on human and nonhuman capital were closely similar.In real terms, the growth of total capital stocks accounted for two-thirds of the growth in real GNP, 1929–1966. One-third of the growth is attributed to residual forces, chiefly economies of scale, changes in inherent quality of human and natural resources, changes in values and motivations, and changes in rates of utilization of capacity.The growth of the ratio of real intangible stocks to real tangible stocks accounted for less than half of the increase in total factor productivity 1929–1966. This is significantly less than the contribution of intangibles as estimated by Denison, and the author adduces several reasons why his estimates may understate the contribution. Nevertheless, it seems that the net effect of the residual forces enumerated above must also have made a substantial contribution to the growth of tangible factor productivity and real GNP over the 37-year period.

Notes: The interpretation of Turam data is treated by means of a development of the conventional approach to this type of data. The development consists of a curve matching technique based upon a line current approximation to the true induced current pattern.The technique requires computation facilities which are readily available in modern programmable calculators.Practical examples of the use of the method illustrate that it can reveal information concerning the geometry of a conducting body which would not be gained by the conventional approach.

Notes: “Remote sensing” techniques have been used for many years as an exploration tool; broadly speaking, any method using sensors not directly connected to the earth's surface falls into this group.It is preferable, however, to use the term solely with reference to a number of new sensors which have recently become available to earth scientists for the detection of various radiations of the electromagnetic spectrum in the wave length range from 0.1 micron (UV) to some centimeters including the visible and infrared regions.Radiations artificially induced in the earth (active sensing) or spontaneous radiations (passive sensing) can be detected. Some of the bands investigated seem promising for application to geological surveys, especially using sensors on aircraft and satellites, which allow synoptic and large scale investigations.A brief account is given of the results already achieved and of future developments such as the ERTS and manned satellite (post Apollo) “earth observation” programmes.The potential role of Europe in the field is discussed.Details are given of some applications of thermal I.R. imagery to geological and vulcanological problems, with special emphasis on the research carried out in Italy.

Notes: A simple calculation procedure that gives the equilibrium temperature in geothermal measurements reduces the reading time in field work from reported 60 minutes to about 10 minutes.

Notes: Boundary-value problems in steady-state current flow were solved numerically in bispherical coordinates for a sphere of arbitrary conductivity in a half-space. Solutions for the potential on the surface of the half-space were examined for the cases where both current sources were on the surface, one source on the surface and the second between the surface and the sphere, and one source on the surface and the other in the sphere. Results show a great similarity with the layered case when the buried electrode is placed between the surface and the conducting region. Such a buried electrode configuration makes it possible to obtain an accurate measurement of the depth to the conductor in both cases. A model with the current electrode placed in a conductive sphere is compared with a three-layered model with the source in a conductive intermediate layer, and results indicate that the lateral extent of a finite anomalous zone can be estimated using these limiting curves. The validity of these theoretical calculations for buried spheres was confirmed experimentally by tests conducted on an analog model.

Notes: In mathematical statistical filtering the deconvolution problem can be solved by two different methods:〈list xml:id="l1" style="custom"〉1by inverse filtering2by calculating the prediction error.Both methods are well known in the theory of Wiener filters.If, however, the generating process of the signal is known and can be described by a set of linear first order differential equations, then the Kalman filter can also be used to solve the deconvolution problem. In the case of the inverse filtering method this was shown by Bayless and Brigham (1970). But, while their method can only be used if the original signal is a colored random process, this paper shows that in the case of a white process the prediction error filtering method is a more appropriate approach. The method is extremely efficient and simple. This can be demonstrated by an example which maybe of special interest for seismic exploration.

Notes: The use of the electrical image method in calculating the potential of a source in the presence of a buried conductive sphere proves to be difficult because of the great number of terms making up the potential formula. The disadvantages contained by this method are avoided here by resorting to the theory of graphs. In view of this aim the “propagation” of the electrical images due to the sphere has been represented by an infinite graph to which an infinite matrix has been attached.Taking this as a basis several FORTRAN IV programs for the computation of resistivity pseudo-sections for various electrode configurations have been coded, and a great deal of such pseudo-sections have already been calculated with an IBM-360 computer. Using these results, recommendations regarding both the methodology of the geoelectrical prospecting of spherical shaped conductors and the most suitable way of building resistivity pseudo-sections are developed.

Notes: An account is given of the use of the square array technique in investigating the surface effects of rotational anisotropy when the axes of anisotropy are inclined to the surface. It is shown that, as with other arrays, two anisotropy parameters 〈inlineGraphic alt="inline image" href="urn:x-wiley:00168025:GPR249:GPR_249_mu1" location="equation/GPR_249_mu1.gif"/〉 and n can be derived by varying the array orientation.On the basis of these considerations, the effects of such anisotropy on the values of the mean apparent resistivity and azimuthal inhomogeneity ratio normally obtained in square array measurements is reviewed.Particular attention is paid to the variation of resistivity with orientation and it is noted that, in areas of moderate anisotropy, this variation is lower for the square than for the Schlumberger array.In addition to this advantage, the azimuthal inhomogeneity ratio obtained from square array measurements may be used to indicate the severity of anisotropy in an area and two field examples of this use are given.Where anisotropy is severe, gross variations of apparent resistivity with orientation are obtained with either square or collinear arrays. In these circumstances, the use of crossed measurements is considered and the particular stability of the crossed square array demonstrated.

Notes: Electrical resistivity sounding was attempted with success in 1960 on the surface of the Nile water in Khor Kundi El-Bahari, the starting place for the construction of the offset channel of the High Dam. The method was applied to determine the depth to the upper surface of the granite below the alluvium and Nile water. The success of the method conducted at two stations in the Khor is attributed to the favourable geological conditions of the section which consists of nearly homogeneous layers besides the good earthing conditions of electrodes dipped in water. The high resistivity contrast between water and granite facilitates interpretation of sounding curves. Factors interfering with the results of interpretation are mentioned.

Notes: This paper presents a dot chart for calculating gravity effects from two-dimensional bodies with the addition of a supplementary set of curves which can be used to determine the “end corrections” to modify the calculated effects when the length of the body is not relatively long with respect to the horizontal dimensions of the cross-section. The use of the chart is demonstrated by different examples. The results of theoretical cases amenable to mathematical treatment and computer results both compare favorably to those computed using the present chart.A fundamental incentive of constructing this chart, in a final form ready to use, is to make it available to gravity interpreters for utilization. Future effort in chart construction is thereby avoided.

Notes: By applying dynamic corrections a seismic trace recorded at a distance x from the energy source should be varied in such a way as to obtain a trace which would be recorded at zero-distance, i.e. at the source itself. Only such a zero-offset-trace contains the correct sequence of reflection coefficients (reflectivity function), whilst all other traces contain a distorted reflectivity function. In the simplest case, the reflectivity function is compressed over a shorter time whereas in more complicated cases a partial inversion of the reflectivity function results. This happens when some of the reflection hyperbolae intersect one another.The reconstruction of the true zero-offset reflectivity function by the application of dynamic corrections can only be an approximative process. In the first case mentioned we must expect a decrease in accuracy of the corrected trace in comparison with a zero-offset-trace. In the second case, where intersections of the hyperbolae occur, accurate reconstruction is clearly impossible.The problems are discussed with the help of theoretical and practical examples.

Notes: Fourier transform techniques have been used to calculate the theoretical filter (amplitude) response function of Nth order vertical derivative continuation operation. The amplitude response functions of the vertical gradient and its continuation follow from the same. These response functions are subsequently used to calculate the weighting coefficients suitable for two dimensional equispaced data. A shortening operator has been incorporated to limit the extent of the operator. For comparative study, some of the developed coefficient sets and the one presented in this paper are analysed in the frequency domain and their merits and demerits are discussed.

Notes: The comparison of a group of continuous total field stations in Ireland with the record of the total field from Valentia Observatory enables the errors which would be involved in using the Observatory as a diurnal correction base to be examined. For the most part, for a single correction, these errors lie between ± 2 and ± 6 gammas. However, they have three notable characteristics: (i) they are not closely dependent on the magnetic ‘noisiness’ of the day, (ii) they are only marginally reduced by the application of station-base time differences and (iii), they are strongly related to differences between the amplitude of the daily magnetic variation at the station and at the base. A permanent geographical basis for the latter differences enables a system for the estimation of the errors to be proposed.

Notes: The automatic picking of seismic sections becomes delicate with the presence of blind zones breaking up the continuity of horizons. This makes it difficult to establish correlations between reflections coming from above and below these blind zones.With the help of a certain number of characteristic parameters, a computer capable of storing a great quantity of data makes it possible to identify the horizons bounding a blind zone. Once this investigation has been made, the coherence between these horizons still has to be measured by making a factorial analysis of these different parameters. The statistical decision functions involved in this analysis are well adapted to computer logic. They enable the probability to be given with which the horizons located above and below blind zones correspond.A program has been worked out to provide the degree of coherence between such horizons.

Notes: An operative technique is described along with a method of representation of Induced Polarization values obtained over homogeneous rocks against the electrical power per unit volume.The results of similar experiments over two-layer ground, are shown according to the same operative technique and method of representation.With the method of representation suggested in this paper it is possible to distinguish discontinuities and to get information about the thickness of the upper medium.

Notes: Nomograms are presented for the purpose of rapid computation of the apparent resistivity functions from the field data for symmetrical and unsymmetrical linear electrode arrays.

Notes: Apparent resistivity measurements with the square array technique in the vicinity of a dipping interface have the advantage over collinear array methods that they are less dependent on orientation of the array.In order to exploit this, existing potential solutions for the dipping interface problem have been adapted for the computation of apparent resistivities over such a feature using a square array.Comprehensive interpretation techniques covering this problem are given and the limitations imposed by residual array orientation effects are discussed.

Notes: In the interpretation of anomalies obtained with moving source-receiver dipole electromagnetic surveys, use is frequently made of the so-called phasor or vector diagrams. Most such diagrams are based on model experiments or theoretical calculations on bodies of simple geometry. If the anomaly at some given coil-separation and frequency is known it is possible to predict the anomaly at some other separation and frequency. While the results of such predictions often agree admirably in the laboratory experiments, wide, systematic discrepancies are observed in full-scale field work. Some of the discrepancies can be explained by various phenomenological arguments and in this respect the effect of overburden conductivity appears to be more serious than is generally supposed. The effect of phase rotation due to the overburden is discussed in detail.The paper is mainly a cautionary note based on some full-scale data of multi-frequency, multi-separation surveys against the blind use of vector diagrams, but it also discusses the extent of the extra information and interpretation aid provided by such surveys.

Notes: The considerable increase of sensitivity of new magnetometers allows the elaboration of magnetometric maps with contour intervals of fractions of one gamma. On these maps, small anomalies appear which had never been visible before. They are caused by susceptibility contrasts within the sediments.The areal distribution of these small undulations of the magnetic field depends on tectonics, therefore their analysis can give useful information about the tectonic pattern of the sediments. This paper discusses the automatic transformation of these small anomalies into tectonic units. The problem is solved by a method called Digital Template Analysis which has already yielded very useful results in gravity interpretation.The application of the method described is restricted to surveys executed by high sensitivity magnetometers. Therefore it is supposed that in most oil exploration problems these magnetometers will replace instruments with lower sensitivity. The improved magnetometer surveys in combination with the interpretation method described represent a most efficient, fast and unexpensive reconnaissance method.

Notes: In this paper it is shown how one may obtain a generalized Ohm's law which relates the induced polarization electric field to the steady-state current density through the introduction of a fictitious resistivity defined as the product of the chargeability and the resistivity of a given medium.The potential generated by the induced polarization is calculated at any point in a layered earth by the same procedure as used for calculating the potential due to a point source of direct current.On the basis of the definition of the apparent chargeability ma, the expressions of ma for different stratigraphie situations are obtained, provided the IP measurements are carried out on surface with an appropriate AMNB array. These expressions may be used to plot master curves for IP vertical soundings.Finally some field experiments over sedimentary formations and the quantitative interpretation procedure are reported.

Notes: The interface phenomena for low periods, i.e. the initial oscillations, and the cut-off periods are two characteristic features in Magnetotelluric Sounding curves. A method is proposed to distinguish between transitional and homogeneous layered earth by means of these two features.

Notes: In the linear filter method of interpreting resistivity sounding data, as developed by Ghosh (1971), it appears that the filter function in the x-domain approaches an oscillating function for both large positive and large negative abscissa values. In the present note the reason for this oscillating behaviour is derived, and a possible practical application is indicated.

Notes: Amplitude spectra of input FM signals used in the vibratory source method of seismic exploration often show undesirable oscillations near the initial and terminal frequencies. These oscillations have an effect on the correlation background and distort the output signal. Considerable improvement in reducing the amplitude of these oscillations is obtained using a proper taper fuction. Attention is given to the relation between the tapering time and bandwidth of the spectrum.Analyses of the spectra of the received data from vibratory sources show considerable attenuation in comparison with the original field sweep. Since the matched filtering process will result in a series of waveforms which have the shape of the autocorrelation of the input signal, consideration is given to the autocorrelation function and its zero-lag coefficient of the FM signal in the presence of attenuation. A method has been developed which compensates for the attenuation and recovers the distortion of waveforms when the received data is correlated.The design of a waveform shaping filter for vibratory source data is given to reduce the influence of phase distortion on the received waveforms as well as to increase S/N ratio resolution. Parameters used for this filter are based on the properties of the FM signal and its autocorrelation function.Several examples from field data are presented to illustrate the methods. The results indicate that the use of the above techniques yields sections with good frequency resolution and improved S/N ratio.

Notes: Reddy, I. K., D. Rankin, 1971, Magnetotelluric Effect of Dipping Anisotropies, Geophysical Prospecting 19, 84–97.A solution is obtained for the magnetotelluric effect in the case of multi-layered earth, each layer containing dipping anisotropy, with the strike of anisotropy oriented at an arbitrary angle to the measuring directions. A technique to compute tensor impedances and tensor apparent resistivities is presented and the importance of anisotropies in magnetotelluric interpretation is discussed.
