Notes: Underwater photogrammetry is being used in the particularly hostile environment of the North Sea where it has been put into commercially viable operation. The authors discuss underwater photogrammetry related to other means of inspection of oil platforms. They also deal with operational experience of 35 mm and 70 mm cameras, camera calibration, the provision of control and photogrammetric observations and data analysis. The demand for underwater photogrammetry continues to grow.

Notes: This paper summarises the theoretical and practical development of’an analytical system for close range photogrammetry. The system uses the extended bundle method of phototriangulation and a sophisticated least squares algorithm. A description is given of computer software, and aspects of statistical testing and gross error detection are discussed in order to assess the accuracy potential. Applications of the system, for precise co-ordination of a target range and camera calibration are outlined.

Notes: A photogrammetric system that is suitable for shallow water detailed mapping at scales from 1:50 to 1:500 for coastal and harbour engineering projects is described. The results from tests using automatic 35 mm Canon cameras on an elevated platform to determine the accuracy of planimetric and depth co-ordinates are presented. The economic benefits of stereophotography through shallow water rather than underwater photography are discussed.

Notes: This paper reviews the growth in the use of photogrammetric techniques in architecture, principally in the United Kingdom, over the past ten years. The work of the various establishments involved in architectural photogrammetry is described and the results of a questionnaire, distributed within the architectural profession, are analysed. Some comparisons are made with developments elsewhere in Europe.〈section xml:id="abs1-2"〉〈title type="main"〉RésuméOn examine dans cet article l'extension qu'a connue l'utilisation des méthodes photogrammétriques en architecture au cows des dix dernières années, principalement dans le Royaume-Uni.

Notes: A method of delineating the extent of floods has been devised involving the establishment of flood surfaces and the creation of photogrammetric digital terrain models. These two data sources are combined in a computer aided map production system and comparisons are drawn between the efficacy of different forms of terrain modelling in a floodplain environment.〈section xml:id="abs1-2"〉〈title type="main"〉RésuméOn a mis au point, en vue de déterminer l'étendue d'innondations, une méthode numérique combinant les notions de surface innondable et de modèle numérique de terrain (MNT); on se pose le problème du choix du MNT dans un environnement de plaine innondable.〈section xml:id="abs1-3"〉〈title type="main"〉ZusammenfassungAngabe eines Verfahrens zur Ableitung der Ausdehnung von Überschwemmungen, wobei die Flut-Oberfläche bestimmt und photogrammetrisch digitale Geländemodelle erzeugt werden.

Notes: In the course of the nearly two decades since the revised SNA was developed, the role of pensions and insurance in the developed western economies has been significantly altered. The United Nations System of National Accounts (SNA) is not fully consistent in its treatment of pension and insurance transactions. This paper examines whether, in view of the changed institutional context, a modification of the SNA treatment of this complex of flows would be desirable. It investigates the impact on household income and saving of adopting a somewhat more consistent transactor/transaction approach for all pension and insurance transactions. Four main topics are covered: (1) social security, (2) private pensions, (3) life insurance, and (4) casualty insurance. Each is considered in terms of the treatment of contributions, the treatment of benefits, and the handling of reserves and the income generated by them. The same sorts of problem arise in all four cases.

Notes: Production maximization, together with an appropriate distribution of income and wealth, can no longer be considered as the exclusive objective of socio-economic policies. Economic and social life is accompanied by numerous hardships, constraints and damages which demand to be minimized. Combining these dual aims is not easy as no single model has yet been set up taking into account all these inter-relations. However, one may try to reduce the uncertainty about the statistical material that could be required for decision-making in this new context.

Notes: This paper explores the choices and potential biases involved in valuing one type of government expenditure, medical transfers, and in estimating its antipoverty impact. Three methodological approaches–(a measure of) government costs, (a measure of) cash-equivalent values and (a measure of) funds released–are contrasted both in concept and in practice. We assign benefits to individuals after assuming that Medicare and Medicaid provide insurance to all those who are eligible. The resulting estimates for 1968 and 1974 illustrate the efficacy of these medical transfers in reducing the number of persons in poverty. Two recent studies, one by the Congressional Budget Office, and the other by Morton Paglin, further highlight the importance of medical transfers for estimating poverty, despite the fact that we do not wholly agree with the methodologies which they employ. Our results indicate that in the aggregate, while medical care transfers have a substantial impact on poverty, the choice of a specific estimation approach has little effect on poverty estimates. However, for the elderly and possibly also for other groups (e.g. the rural poor), choice of estimation technique is quite crucial for estimating the extent of poverty.

Notes: In studies of income distribution household income is the common measure of household welfare, although household per capita income is better since it automatically “corrects” for household size. Perhaps the continued use of the former is a consequence of the belief that in practice the two give very similar results. This paper shows that in many cases those results differ substantially. Policy prescription based on household income rather than household per capita income can be very defective. The paper compares results according to the two income concepts for Malaysian data. U.S. data are then used in a comparison over time.The disparity between the two Malaysian distributions is illustrated by their cross tabulation. A quarter of the households in the lowest forty percent of the household income distribution is in the upper three quintiles of household per capita income; and 10 percent of the same lowest forty are in the highest two quintiles of the second distribution. The paper also shows that the distribution of benefits from public education-measured as the public costs of school years—is very inegalitarian if household income is used. The reverse occurs if household per capita income is used. Similar reversals occur in comparisons involving partitions by occupation and sex of head of household. Women-headed households, for example, have sub-mean household incomes but their household income per capita equals the mean. The paper also examines the differences in the age-income profiles of the two distributions. It then considers whether the much discussed secular stagnation in U.S. measures of inequality is changed if household income per capita is used rather than the usual household income measure. Use of the per capita concept results in a slight decrease in U.S. inequality between 1947 and 1972. Appendix 2 explores how long term growth in per capita incomes and the associated changes in the size composition of households may affect measurements of inequality.

Notes: Provision of “market goods” follows the decision rules of traditional microeconomics; pricing and resource allocation for such goods tend towards Pareto optimality. The provision of “collective goods,” by contrast, depends on political (or quasi-political) collective decision processes; beneficiaries often receive a share of collective goods free of charge or well below average or marginal (private or social) costs. No inherent tendency towards optimality may be presumed and separate analysis of collective goods becomes an essential part of national goals accounting.The national-income-accounts (NIA) distinction between personal consumption expenditures (PCE) and government purchases of goods and services corresponds roughly to a division between market goods bought by the consumer and a major category of “collective goods” (i.e. “public goods” provided by government). However, a significant proportion of PCE represents “collective goods” paid for by government, business, or nonprofit organizations and provided on behalf of the consumer, whereas a part of NIA government purchases represents services paid for by the consumer (i.e. “market goods”).This article develops operationally meaningful distinctions among “market goods,”“collective goods,” and “tied aid” (a mixed category with market-good and collective-good characteristics). These distinctions are determined by the nature of the decision processes–rather than by the characteristics of the beneficiary or the supplier. This classification is related to the national income accounts and major discrepancies are pinpointed. The blurring of the distinction among market goods, collective goods and tied aid is found to be most consequential in the NIA treatment of “education” and “medical care” services. NIA data for these two services are restructured for national goals accounting purposes in order to illustrate both the quantitative importance and the empirical feasibility of classifying benefits by their respective decision processes.

Notes: Recently there has been discussion concerning the renewal of the volume measurements of public sector services. This renewal has been proposed e.g. in the recent United Nations Draft Manual on Public Sector Statistics. In the present paper we discuss some theoretical and practical problems connected with this renewal. According to some preliminary calculations concerning the Finnish educational sector, the new methodology might lead to a considerable revision of figures of output and labour productivity in the public sector. The revisions are of such a quantity that they might cause significant changes in the measurement of the volume of the total gross domestic product. This is a fact which may still require reflection before the new methodology is generally introduced, even though the revisions as such may be highly desirable from several aspects.

Notes: Structural relationships estimated from data obtained in a benchmark study of the expenditures and prices of 16 countries are used to develop a table of real gross domestic product and shares of gross domestic product devoted to private and public consumption and investment for each of over 100 countries in the years 1950 and 1960 through 1977. Price level estimates for total product and the three components are also provided.

Notes: Taxes as well as government expenditures tend to transform income distribution; the higher they are in relation to GDP, the higher their potential influence appears. It is easier to trace the incidence of taxes than that of expenditures and studies of effects of expenditures on income distribution are not frequent. Changes of fiscal legislation and deficiencies in reporting systems and statistics frequently found in developing countries complicate the task still further.An investigation of this type in a developing country has to face a poorly developed data base and take advantage of different and dispersed sources of information.This paper presents the methodology used for estimating the influence of government expenditures a n income distribution in the case of Venezuela. Although the incidence of fiscal activities on income distribution in Venezuela might not necessarily be the same as in other countries, Venezuelan sources of information are not very different from those existing in other countries of similar level of economic and statistical development and procedures used could appropriately be adapted to other countries.

Notes: For estimates of the wealth distribution Canada depends on household surveys taken at 6–7 year intervals. The latest data from this source refer to household balance sheets in the spring of 1977. A comparison with 1970 shows that there is little change in the composition of wealth held by households but that inequality of the wealth distribution has been somewhat reduced. Wealth data by age of family head is presented in order to describe more fully the wealth distribution and composition in Canada.Weaknesses in the data are discussed as well as the difficulties of making appropriate adjustments to the data at the micro record level. For policy evaluation and formulation purposes the lack of comprehensive estimates inclusive of pension wealth as well as the small sample size (12,700 usable records) have been perceived as greater obstacles to utilizing the data than the underestimate in aggregate assets and debts which affects more the higher than the middle and lower ranges of the wealth distribution.

Notes: The article refutes the contention that Brazil's development has not benefited the poor and that rapid growth has had a polarizing effect on the distribution of income. It uses the National Household Expenditure Survey of 1974–75 to try to quantify the extent of poverty and concludes that the incòme levels of the poor have been underestimated in the past. The evidence suggests also that occupational and regional variables are powerful determinants of income stratification. Wage rate statistics convey information about long-term trends in income. The article notes considerable increases in rural wages during the 1970s as well as wage improvements in the urban informal sector. Shifts in the structure of employment have probably been the most powerful cause of economic improvement in Brazil. The enormous absorption of rural-urban migrants occurred without a flooding of the lower income urban categories. Social indicators and statistics referring to ownership of household durable consumer goods corroborate income and labor market evidence to the effect that there has been considerable progress for the poor during the 1970s. The article reviews statistical evidence bearing on distribution. There is little doubt that the distribution of income in Brazil is very skewed. It is not possible, however, to come to conclusions about changes that might have occurred in the degree of inequality over time. Finally, the article includes data on the “distribution of education” and the “distribution of life expectancy” and notes improvement over time in both.This article takes advantage of the Brazilian population census of 1980 to bring up to date some of the statistical material that bears on the issues of poverty and income distribution. First, the article describes the overall context of Brazilian development since 1960. The second part analyzes the extent of poverty in the mid-1970s. The third part deals with trends in wages, employment and selected welfare indicators. The last section briefly summarizes the information relating to income distribution: what is the extent of skewedness and how has it evolved over time?

Notes: This paper outlines a conceptual basis for the measurement and analysis of levels of welfare. It reflects the thinking that has been ongoing in the World Bank's Living Standards Measurement Study. Three alternative approaches to the measurement of welfare for the purpose of ranking households are surveyed, and the data requirements and analytical techniques for each highlighted. Various issues are discussed regarding the causal analysis of welfare levels and the changes in them. It is argued that the consideration of several dynamic aspects of welfare is significant for the identification of the poor and the potentially poor and for more accurate measurement of levels of living between socioeconomic groups.

Notes: The question addressed in this paper is: Why can't we have a good measuring rod of the economic and social performance of our society? The answers are basically positive but lie mostly in the direction of (1) avoiding simplistic solutions such as turning the national income accounts into a measure of social welfare and (2) providing the elements of an information strategy to obtain such a measure or more accurately such a set of measures.The proposed information strategy highlights five activities: (1) the presentation and analysis of welfare outcomes, an activity which is analogous to but broader than “social indicators”; (2) social accounting which includes economic accounting, demographic accounting, and time-use accounting; (3) model building and operation which, unlike accounting, are concerned with behavioral or causal relationships used to explain and project welfare outcomes; (4) hypothesis testing to develop new insights into economic and social behavior; and finally (5) the building and maintenance of a data base required for carrying on the aforementioned four activities.

Notes: The importance of non-personal shareholders in Malaysian corporations is widely acknowledged. However, up till now, very little has been known about the nature of these shareowners, their manner of equity ownership (especially their size of holdings hence degree of share concentration), their country of incorporation and how they themselves are controlled i.e. whether Malaysian or foreign. This paper attempts to fill this gap with data compiled from official shareholders' lists of the largest ninety-eight Malaysian incorporated companies engaged in manufacturing, for a point in time 1975–75, which is towards the end of the Second Malaysia Plan period. Some of the empirical findings are then compared with those of a few selected countries.

Notes: This article discusses methods of integrating the “informal sector” in the national accounts of developing countries. This sector, defined generally as composed of producers who do not keep formal accounts, is difficult to capture by usual statistical collection techniques, and therefore is often neglected. The paper develops the requirements for a direct inquiry approach to obtaining data for this sector, emphasizing the need for national, exhaustive, and periodic coverage. It then proceees to propose methods of analysis for informal sector enterprises with and without fixed locations, tailored to the specific characteristics of each trade. The final section presents some results of application of the proposed methods in Tunisia and Niger.

Notes: This paper constructs estimates of income and consumption inequality for the world (124 countries), using various measures of inequality. It then goes on to examine the possible effects of various sources of error in the estimates, and attempts to set rough limits to the size of such effects. Among the sources of error examined are purchasing power parities used for currency conversion, systematic errors in estimates of per capita incomes, differences in age structure, government tax and expenditure policy, and lifetime income effects. The paper concludes that, although the level of uncertainty in the estimates is too great to permit conclusions about, for instance, trends over time, it is clear that the level of world inequality is extreme, and that it is primarily due to differences in average incomes across countries rather than to intra-country inequality.

Notes: In this study, new estimates are presented of the size distribution of household wealth in the U.S. in 1969. Compared to previous studies, its major advance is the inclusion of all marketable or discretionary household assets and liabilities and their alignment with national balance sheet totals. Household disposable wealth (HDW) is defined as the sum of all marketable or fungible assets held by households less liabilities. The Gini coefficient for HDW is 0.72, the share held by the richest one percent of households is 31 percent, and the share held by the top five percent is 49 percent. There is, however, a large variation in the concentration of different household assets. The Gini coefficient is 0.30 for household durables and inventories, 0.69 for equity in owner-occupied housing, 0.94 for bonds and securities, and 0.98 for corporate stock. HDW is then divided into two mutually exclusive components. The first, called “life-cycle wealth,” is defined as the sum of equity in owner-occupied housing, durables, household inventory, demand deposits and currency, and the cash value of life insurance and pensions less consumer debt. This form of wealth tends to be accumulated over the life-cycle for either consumption, liquidity, or retirement purposes. The second, called “capital wealth,” is the sum of time and savings deposits, bonds and securities, corporate stock, business and investment real estate equity, and trust fund equity. Life-cycle wealth is substantially less concentrated than capital wealth. The Gini coefficient for it is 0.59, while that for capital wealth is 0.88. Moreover, among the lower wealth groups, over 80 percent of household wealth takes the form of life-cycle wealth, whereas among the top wealth groups the proportion is under 20 percent. The results suggest substantially different savings motivations between the two groups.

Notes: This paper presents a method of estimating U.S. family net wealth across the entire population, utilizing capitalization of several income items available from income tax microdata. Other forms of wealth, and debt, are indirectly estimated using relationships gleaned from estate tax data. Concentration in the distribution of wealth, and assets such as corporate stock, are measured with Gini coefficients and Lorenz curve analysis and compared to similar estimates of concentration in the distribution of income. Comparisons of the results with previous estimates for the United States are made in the latter section of the paper.

Notes: This paper utilizes Household Expenditure Survey and Consumer Price Index data supplemented by private survey data in an attempt to compare the purchasing power parities of the pound sterling and the Australian dollar for a range of population sub-groups in the United Kingdom and Australia. In spite of the close political, economic, social and cultural ties that exist between these two countries, there have been no attempts to measure differences in living costs and real expenditures. Further, Australia has not been a party to the International Comparisons project of the Statistical Office of the United Nations. This study derives purchasing power parities which explicitly account for variations in expenditure patterns of different population sub-groups. For example, a household living in London intending to move to Sydney will find it useful to have a comparison of cost-of-living between households living in these two cities which takes into account explicitly the general expenditure patterns in these two cities. Due to the nature of the data, it was necessary to employ a new index number method derived by one of the authors.

Notes: “As compared with Hicksian, Harrodian measures of the concept of total factor productivity which rigorously take into account the reproducibility of commodity capital inputs and the technological interdependence of modern production economies are advocated. A number of recent measures of total factor productivity are shown to be variants of the Harrodian approach, and certain problems of aggregation associated with the Hicksian measures are shown to be resolved by the Harrodian measures. An examination of the concepts of technical progress and vertically integrated sectors advanced by Professor Luigi L. Pasinetti and their relation to the Harrodian measures of total factor productivity is made.”

Notes: This paper deals with the influence of differing methods of deflation on the international terms of trade of the Federal Republic of Germany. The question to be discussed is what indices seem best suited for the deflation of exports and imports in national accounts. It will be shown that the use of alternative price indices for deflating exports and imports leads to considerable differences of the results at constant prices and so in terms of trade. In addition, terms of trade are presented by groups of countries.

Notes: The following note is a very concise summary of a paper2 that was presented at the 17th General Conference of the International Association for Research in Income and Wealth at Montvillargenne, August, 1981. As such it may be considered a new paper, although it contains practically all the conceptual issues of the original paper. As in the original paper its intention is only to place these issues before a wider audience, while specific solutions will have to wait for a more detailed treatment. All issues concern certain conceptual dilemmas, arising in particular in the use of national accounts when available concepts do not coincide with those for which data are sought. A decision to change the existing basic concepts would however require not only the support of the scholars in this field but also the co-operation of the users of national accounts. Due to extreme summarizing, certain statements are now fairly compact—compared with the original paper. It is nevertheless hoped that the basic problems still shine through. The following note gives instances in which the traditional national accounts, as established according to existing rules and statistics, may not suffice for actual data requirements, yielding differences in growth rates of several percentage points.

Notes: Empirical research using the opportunity cost approach to estimating the value of non-market work of women tends to focus on the value of actual or potential output produced at home and expected or actual earnings, and assume that a rational decision involves choosing the higher one. Evidence derived from data on young married women suggests that full-time homemakers frequently are unable to provide estimates either of their potential earnings or of the lowest wage they would accept to enter the labor market, and that such estimates as they do provide are not soundly based. We also found that using wages of women in the labor market to estimate the value of the home time of full-time homemakers involves upward bias. We conclude that there are good reasons for caution in using the opportunity cost approach.

Notes: How have government transfers altered the distribution of income, the level of work effort, and the rate of personal saving? Most scholars approach this question by comparing the current level of government transfers with the unrealistic counterfactual of a zero-transfer situation. This method overlooks the fact that nongovernment transfers existed before government transfers and the possibility that private transfers might have grown more if government transfers had grown less.This paper explores the significance of one private alternative to government transfers-namely, direct interfamily giving of cash, food, and housing. Fragmentary evidence suggests that such interfamily transfer was quantitatively more important than governmental transfer for these purposes thirty years ago, but is now only half as great. If current government transfers are conversions of, or substitutes for, interfamily transfers, then it follows that some of the benefits of government transfer “slide” over to “secondary beneficiaries,” i.e. those who would have made the private transfers. Further, it follows that the effects of government transfers are not much different from those of the private transfers which they replace.

Notes: In this paper we describe a micro consistent data set for Canada for 1972, assembled with general equilibrium tax policy analysis in mind. We stress the methodology used and in a number of tables report its main features.In the data set the separate detail contained in input-output transactions tables, national accounts, household income and expenditure data, taxation statistics, foreign trade statistics, flow of funds and other sources is adjusted for mutual consistency. The final result is a micro consistent data set in which demands equal supplies for all products, zero profit conditions hold for industries and all agents’ demands satisfy their budget constraints.The motivation for data assembly is the currently widely used practice of calibrating “empirical” general equilibrium models so as to exactly reproduce a base year data observation as an equilibrium model solution. This procedure enables empirically based models to evaluate counterfactual equilibria in a way which corresponds to comparative static analysis in theoretical literature.More detail on the data set is available on request in appendices deleted from the published version of this paper due to space constraints.

Notes: This article deals with some aspects of the compilation of input-output tables (I.O. tables). A global view is given of the way in which I.O. tables are compiled in The Netherlands. It is indicated that in The Netherlands a number of developments are in progress that have led to an extension of the uses that are made of I.O. tables. The changing demands on I.O. tables that result from these developments can be met in future to an important degree. This has been made possible by extending and improving basic statistics and by increasing the uses made of automation facilities. Some problems remain, however, and one of these problems takes a central place in this article. This is the problem of accuracy and continuity: how can yearly I.O. tables be compiled that combine accuracy with consistency over time. Accuracy means here that the tables should be as complete as possible and in optimal accordance with all available information. Consistency over time means that estimates of details of I.O. tables compared with the same estimates for previous years reflect real economic developments. It is obvious that those two demands may conflict, particularly for years in which new information becomes available. It then must be decided whether accuracy or consistency in time deserves priority. What problems result from this decision and what are the consequences for the yearly I.O. tables? The problems arising from the conflicting demands of accuracy and continuity apply to the Netherlands in the last few years. This led to a revision of I.O. tables and national accounts for 1977. This revision resulted in an increase of estimated national income of more than 6 percent. For some components the adjustments have been much larger; this is particularly true for the services sector. More information on the 1977 revision is given in an annex.

Notes: Two ways of estimating the value of housework are currently used. One is the opportunity cost approach, which sets the value of work done at home equal to the income the person could earn in the labor market. The other is the market cost approach, which uses the cost of hiring someone to do the housework to determine its value. In this study we use data on earnings of female clerical workers with various patterns of labor force participation to obtain estimates of the opportunity cost of hometime for such women. We find that potential market earnings do not provide an acceptable estimate of the value of housework, and suggest that using the wages of general household workers is a better approach.

Notes: By expenditure on education, health, housing and other public services, governments provide many goods and services which are alternatives to, or additional to, household expenditure on consumption. In most Western national accounts, the two forms of consumption are rigidly separated. Yet the combination of the two–the concept of total household consumption–has obvious importance for the measurement and comparison of living standards and for the formulation and analysis of policy. This concept is recommended as an additional aggregate in the revised SNA. It is displayed in the UN International Comparison Project (ICP). It is used as a major aggregate (“total consumption of the population”), although hitherto generally excluding nonmaterial services, in the Material Product System. Yet it is rarely shown explicitly in Western national accounts. One reason is the slow progress in the analysis by purpose of government expenditure.This paper shows how far figures of total household consumption, and of its division between collective and private consumption, can in fact be derived, for the advanced countries, from the data provided to the UN Yearbook of National Accounts, supplemented b y the ICP. The results show first the wide national variations in the relation between the two forms of consumption but, secondly, the gaps in information on this crucially important topic. The relation between direct government expenditure for collective consumption and transfer payments to households (“social income”) is also examined. High and low levels of these two forms of State support to consumption reinforce each other almost as often as they offset each other. But, again, the data provided by national accounting statistics are very incomplete.This paper was prepared for the 16th General Conference of the IARIW, August 1979.

Notes: In an earlier paper, we presented estimates of capital gains for a number of categories of assets owned by Belgian households. The purpose of the present paper is to see how the distribution of disposable income between socio-economic groups is modified when one adopts a “broadened” definition of income which includes capital gains corrected for losses of purchasing power.The main result of the study is that at current prices, the adoption of a broadened definition of income strongly increases disparities between socio-economic groups. However, when one takes into account losses in purchasing power, conclusions differ according to the period analyzed. For the years 1953–68, it appears that the distribution of broadened disposable income is more unequal than the distribution of disposable income. For the years 1969–77 when inflation was high, the adoption of a broadened definition of income has reduced disparities, with the important exception of old age pensioners.

Notes: International financial relationships should be interpreted in the context of a comprehensive conceptual framework; this paper advocates the use of concepts developed to measure and analyze balance of payments flows. Broad-based, empirical estimates of the international wealth of most countries of the western world are presented on the basis of cumulating balance of payments flows over a lengthy period. Among the more interesting aspects of the results are: the importance of intra-industrial country capital flows in a global context; the propensity of debtors to regard a larger share of their aggregate external debt as long term than do their creditors; the overwhelming importance of banks located in the industrial countries in global external asset and liability positions, and the preponderance of short-term positions taken by those banks; and the tendency for balance of payments records to report more direct investment assets than liabilities. The paper also contains some observations, based on the cumulations of balance of payments capital flows, concerning the nature and size of certain deficiencies in alternative sources–particularly the World Bank's Debtor Reporting System, and the Bank for International Settlements' banking data–of information on outstanding external debt positions.

Notes: The unsolved problems of measurement of international transactions may have consequences which are serious both for policymakers and for those undertaking research. Emphasis is placed on the need for users of data to understand and take into account the limitations and qualifications attached to them.The causes of deterioration in the quality of estimates of international transactions likely lie in their changing pattern. After a brief discussion of the basic sources and methods used, the paper selects for comment possible measurement problems related to inflation, taxation, illegal transactions, and affluence.A description follows of the improvement to data which has been achieved through exchanges and comparisons between trading partner countries. Efforts to use econometric analysis to point to error sources have, however, proved less rewarding.The paper concludes with a section on the linkage of flow and stock estimates.

Notes: Although the functional and institutional distributions of income are integrally connected to individual living standards and other development policy objectives, these dimensions are rarely given prominence or even accommodated within standard national accounting frameworks. This paper summarizes research on the estimation of a social accounting matrix (SAM) for Malaysia for 1970 in which the distribution of income between different factors and socio-economic groups is identified. It is the latest of a series of case studies involving some of the authors and is, perhaps, the most detailed of its kind. The study departs from the United Nations SNA guidelines at various points. The SNA basically proposes a commodity balance approach to national income accounting. In giving equal emphasis to income/outlay accounts as to the production accounts, the present study has brought together data from two major primary sources: a household expenditure survey and a production survey. Their combination poses several problems which are discussed in the paper. It leads to an integrated picture, in matrix form, of the interrelationships between income distribution and production structure in the Malaysian economy.Both the factor and household accounts in our SAM are disaggregated according to race and the geographic distinction between Peninsular and East Malaysia, with an urban/rural split within Peninsula Malaysia. The Peninsula labor force is further disaggregated by education level, while its households are then subdivided according to the employment status of main income earners. Arguments for and against these choices are presented.Some other aspects of the study can be noted. First, the distinction drawn between East and Peninsular Malaysia is desirable not only because of the inherent interest of the regions but also because of large differences in data availability and hence in estimation methods. Secondly, to complete our SAM it was necessary to estimate inter-household transfers, being the institutional analogue of inter-industry commodity flow. And finally an attempt has been made to impute the labor component of unincorporated business income. These, then, are the major problems which had to be overcome in our attempt to quantify the generation, distribution, and redistribution of income within Malaysia in a SAM framework.

Notes: The Wealth-Income Ratio of households, although less known than the capital-product ratio, has not been ignored by economic analysis. But most of the studies concerning this ratio put the stress on one unique cause of variation: the saving ratio of households. Doing so, they neglect other important factors such as the behaviour of households in incurring debt, and the influence of inflation on the variation of nominal income and on capital gains. This paper first provides a simple formula expressing the Wealth-Income Ratio as a function of all these factors. Then it shows, using data from France and United States, that this relationship is a useful tool for analysing the observed evolution of the ratio. Finally, it comes back to the famous question of the “constancy” of the Wealth-Income Ratio in the long run.

Notes: This article on the distribution of wealth among individuals in the United Kingdom presents recent work on the effects of including pension rights and the significance of sex, age and marital status. It describes the rationale for including the accrued rights in occupational and State pension schemes (funded or unfunded) and the methods of estimation used. For funded schemes the rights are valued as the accrued liability of the schemes to their members, and for unfunded schemes similar liabilities are hypothecated; these estimates of the value of accrued pension rights involve assumptions about future earnings and interest rates. The trend in average marketable wealth with age is upwards until advanced years when it slows down or slightly reverses. Adding occupational pension rights only slightly raises the trend for females but has a bigger effect for males. Adding State pension rights raises these upward trends until the age of 60 after which there is a decline. For marketable wealth on the average males are wealthier than females but less wealthy if single, divorced or widowed. Adding occupational pension rights improves the relative position of males; adding State pension rights cancels this out. The effect of marital status rises with both age and sex and therefore a detailed three-way analysis is made. For females widows are on average the wealthiest; for young males the married; for older males the single. Using Theil's coefficient of entropy for comparing the inequality of wealth, the addition of pension rights reduces inequality by two-thirds. Age accounts for only 6 percent of inequality for marketable wealth but for 31 percent if pension rights are included.

Notes: The development of social protection accounts is described and the relationship between social security and welfare expenditure (as recorded in social protection accounts) and expenditures in the national accounts is discussed. Proposals are put forward for achieving co-ordination between social protection expenditure and expenditure recorded in the national accounts, and these are illustrated by reference to Irish data. The future development of social protection accounts by the inclusion of fiscal benefits, which are not recorded in the national accounts, is also considered. Finally some references are made to the use of the social protection accounts and the development of data relating o the numbers of persons covered by social protection and the numbers of beneficiaries.

Notes: This paper analyses the weakness in labour demand which appeared in 1973–78 in France, Germany, and the U.K. and attempts a comprehensive assessment of it. Hitherto, the situation in labour markets has usually been measured by official figures of the registered unemployed which tend to understate unemployment itself and neglect other dimensions of labour slack, such as reversal of previous migration flows or declines in labour force participation or in working hours which may contain highly significant cyclical movements cushioning unemployment.The report proposes the adoption of a more comprehensive concept for labour market monitoring, along lines already used in the annual reports of the German Institute of Employment Research. Such an approach presents advantages in economic and labour market policy analysis. A simplified form of the proposed monitoring tables is presented in Annex Tables F-1 to F-4, G-1 to G-4 and U-1 to U-4. They can be considered as a potential satellite to existing national accounts.It is also suggested that analysis of the degree to which labour potential is used be conducted on a regular basis. The possibilities of this approach are outlined in considerable detail in Section V and in the annex. The different dimensions of the use-of-potential account are summarised in Table 3.The report contains a review of the literature on the full employment rate of unemployment and its components. This is one of the major issues on which a judgement must be made in use-of-potential analysis. This review is presented in Section VI of the report.It emerges from the analysis that Germany had the biggest labour slack (8.6 percent of potential) in 1978 though its unemployment rate (3.8 percent of the labour force) was the lowest of the three countries.
