PROBLEMS OF IDENTIFYING AND MEASURING INTERMEDIATE (PRODUCER) SERVICES IN THE COMPILATION AND USE OF INPUT-OUTPUT TABLES*

The paper is mainly concerned with statistical problems relating to intermediate services that arise in the construction of national input-output (I–O) tables. Though these problems are sometimes discussed in the literature, their precise nature is usually not spelled out in any detail and this is done in the paper. The problems are closely related to the company-establishment statistical dichotomy permeating the ultimate sources and allocation of intermediate services. Important examples can be found regarding the statistical treatment of head offices, research and development expenditures, and international trade of intermediate services. Presently used procedures for Canadian and U.S. I–O compilation show evidence of statistical inconsistencies and lack an appropriate framework to utilize full information. The paper suggests a possible approach for reconciling company and establishment data based on industrial organization linkage studies at the microlevel. Considerable empirical support is offered, using various official Canadian statistical publications, to show that the suggested approach is both feasible and has desirable properties. The paper goes on to argue that the contemporary information technology revolution has profound implications for I–O compilation and use with special reference to intermediate services. Four major implications are explained in the context of the growing microelectronics technological change and related literature. Some basic suggestions are put forward with regard to joint-cost allocation and inter temporal comparisons problems with respect to I–O compilation. It also appears that some fundamental rethinking of commonly accepted standard industrial classification conventions may be called for in the near future if I–O tables are to remain relevant and viable. The paper thus features a somewhat broader view of I–O statistical problems than usual and attempts to show that this view is potentially appropriate to questions of economic policy formulation.     

ESTIMATION ERROR IN SECTORAL EMPLOYMENT REQUIREMENTS IN THE ABSENCE OF A DOMESTIC COEFFICIENTS MATRIX IN THE INPUT-OUTPUT ANALYSIS

The objective of the paper is to develop various estimation methods for allocating imports according to their end-use and to make use of the derived domestic transactions for the estimation of gross domestic output and employment by sectors. The standard design in the construction of input-output tables is to provide imports of a sector in the form of a column. These imports are not allocated according to their final use and therefore, total intermediate inputs consist of both domestic and imported inputs. The input-output tables for 12 European countries distinguish three types of transactions: (a) domestically produced inputs; (b) imported inputs; and (c) total inputs. We have made use of these tables assuming that the information on import allocation by end-use and domestically produced and imported inputs separately are not available. The allocations of imports are made under various assumptions and a comparison is made of employment based on artificially generated domestic coefficients with employment based on actual coefficients. The sectors are ranked on the basis of both sets of results. In addition, the ratio of indirect to direct employment for the estimators and actual is derived. The sectors are ranked and the rank correlations between alternative estimators and actual are calculated. Although the ratios differ markedly from method to method, the ranks do not alter.     

REAL INCOME CHANGES O F HOUSEHOLDS IN THE NETHERLANDS, 1977–1983

This paper deals with the construction of statistics on real income changes of households in the Netherlands. Two different figures are computed, called the dynamic and the static figure. The dynamic figure reflects the change in real income as experienced by individuals. It is based on longitudinal data: two panels resulting from an exact match between three files from the Netherlands' IRS. The static figure reflects the change in real income of positions (e.g. of a 60-year old civil servant) instead of individuals. It is based on micro-simulation: changes in wages, taxes, etc. are simulated on a sample of individuals for whom socio-economic and demographic positions are assumed constant.
In the paper we discuss both figures and some other problems, e.g. the concept of real income and the price index. Furthermore we give results for the years 1977–1983 and discuss some differences between the dynamic and the static figure. The most notable result is the large variation in the dynamic figure, exhibiting a very substantial income mobility.     

PROBLEMS OF DETERMINING AND MEASURING THE RELIABILITY OF NATIONAL ACCOUNTS IN DEVELOPING COUNTRIES

Most developing countries have compiled national accounts on a regular basis only for the last few years. It has not yet been possible for them to collect many of the statistics necessary to obtain good coverage of their economic activities by methods which would generally be accepted as reliable. Consequently the checks on reliability imposed by the framework of the national accounts are often absent, and the accounts prepared contain many estimates of doubtful quality. These doubts can usually only be removed as statistics collected by better methods become available. This is proving to be a slow process, partly because of the shortage of trained statistical staff and the competing demands of social and demographic statistics and partly because of the inherent difficulties in collecting good statistics from small businesses and traditional households. The need to define traditional households as producers as well as consumers leads to our demanding extra information from this difficult sector. In addition it is often difficult for the national accounts statistician, and even more so for the user, to find out in the time available exactly how some of the statistics with which he is presented were obtained. When this cannot be done it is impossible to assess their reliability. Thus assessing the overall reliability of national accounts in developing countries for even a limited range of uses is at present largely a matter of personal judgment. The information necessary to make more objective assessments rarely exists and hence the problems which developed countries face in using such information are not yet within the experience of most developing countries.     

A MICROCONSISTENT EQUILIBRIUM DATA SET FOR CANADA FOR USE IN TAX POLICY ANALYSIS

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.     

HYSTERESIS AND THE REGIONAL NAIRUs IN ITALY

This paper investigates the determinants of regional unemployment disparities in Italy. Relying on panel unit root tests and data over the 1977–2003 years, we reject the hysteresis hypothesis and then proceed to estimate the non‐accelerating inflation rate of unemployment (NAIRU) for each of the 20 Italian regions. Our estimates of the regional NAIRUs turn out to be fairly precise and allow us to draw two interesting conclusions. First, the hypothesis of constant regional NAIRUs between 1977 and 2003 is supported by the data. Second, we find that there is a significant degree of heterogeneity among the regional NAIRUs.     

INPUT/OUTPUT ANALYSIS—AN APPRAISAL IN THE CONTEXT OF AS YET AN UNFINISHED EXPERIMENT IN KENYA

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.     

THE TREATMENT OF INTEREST AND NET RENTS IN THE NATIONAL ACCOUNTS FRAMEWORK1

The contention in this paper is that the present method of treating interest and net rents as transfers rather than as payments for services provided creates problems in the measurement of production by industry and that the difficulties encountered in explaining the treatment of interest items in the different tables of the National Accounts are even more apparent when one views the National Accounts framework as an integrated reflection of economic reality. It is argued that the lending of money arises from the stretching out of the production and consumption process, and the interest charges constitute a charge for the administrative services and risk involved. This is somewhat analagous to the charges for hiring out real goods and services. A similar case is made for the treatment of rents with the exception of imputed net rent where it is contended that economic risk is incurred only when production is undertaken for sale and that there should be no entrepreneurial return where the production is for the use of the owner-producer. It is suggested that an alternative treatment of interest and rents as payments for services is more realistic. Its adoption in the National Accounts would eliminate the need for imputations now made to account for the production of financial intermediaries, as well as the unconvincing explanations put forward for the present treatment of interest on consumer and public debt. Finally, it would serve to integrate the production accounts with the financial flows and the related financial structure.     

ESTIMATES OF CAPITAL STOCK BY INDUSTRIES IN THE FEDERAL REPUBLIC OF GERMANY

The main purpose of this paper is to discuss some of the measurement problems in connection with the perpetual inventory method applied for estimates of capital stock. In the Federal Republic of Germany, highly aggregated capital stock data by business sector are compiled by the Federal Statistical Office within its national accounts calculations, while more detailed capital stock estimates by industrial sectors are published by the German Institute of Economic Research (DIW) in Berlin. Because of various gaps in the statistical sources, the accuracy of the capital stock calculations is not yet entirely satisfactory. Aside from the problem of establishing long time series for gross fixed capital formation in constant prices for all sectors, it is difficult to obtain reliable data on the inter-sectoral transactions in secondhand capital goods. In addition, there are problems of determining price indices and service life distributions of the fixed assets in the various parts of the economy. This paper shows a way to arrive at a reasonably close approximation to the latter problem.     

THE DISTRIBUTION OF INCOME BETWEEN SOCIO-ECONOMIC GROUPS IN THE NETHERLANDS

This paper reports on a study designed to improve the information on income flows and income distribution in the Netherlands national accounts by building a bridge between the national accounts and income tax statistics. The methods used are described in some detail, and the significance of the results obtained is discussed. The figures show rather substantial fluctuations in the share of proprietors relative to that of wage earners. This result is not unexpected, since the share of proprietors is much more sensitive to the level of economic activity, but it does limit the usefulness of the figures for short-run economic policy determination. In the longer run, however, they do show what the development of the average incomes of the various social groups has been, and to what extent government action has contributed to that development.     

THE IMPACT OF EDUCATION ON INCOME DISTRIBUTION

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.     

AN EVALUATION OF SUBJECTIVE POVERTY DEFINITIONS: COMPARING RESULTS FROM THE U.S. AND THE NETHERLANDS

In this paper, results of applying the subjective definition of poverty, introduced by Goedhart et al. (1977), in the U.S. and the Netherlands are compared. This definition focuses on the monetary amounts which people consider necessary to make ends meet for their households as provided in response to the Minimum Income Question (MIQ). National data from both countries in the early 1980s are analyzed. In regressions of reported minimum income, corrections are made for the omission of income components and selective non-response. For the first time the relationship between fixed expenditures and the MIQ is examined. Factors significantly related to reported minimum income include household income, household composition, age, education, sex, region, fixed expenditures, and whether the household experienced recent income changes. The income elasticity appears to be smaller in the U.S. than in the Netherlands, while the effects of other socioeconomic factors are greater. On average, the resulting subjective income thresholds are above official poverty lines, but more so in the U.S. than in the Nerherlands. Whether thresholds based on answers to MIQs should be regarded as poverty lines remains open to question.     

MARKET TRANSACTIONS IN THE NATIONAL ACCOUNTS

This paper explains the treatment of market and non-market transactions in the national accounts. Different possibilities of defining these two types of transactions are discussed, and it becomes evident that a strong restriction of national accounts to market transactions only cannot be seriously taken into consideration. On the other hand, a system of supplementary tables is proposed which shows the market and the non-market transactions as such. Examples of tables of this kind are presented for the Federal Republic of Germany.

NEW EVIDENCE ON THE EXPANSION OF SERVICE EMPLOYMENT IN ADVANCED ECONOMIES

In this article the expansion of service sector employment is examined in detail in seven OECD countries, i.e. France, Germany, Japan, Netherlands, Sweden, United Kingdom and the United States, using a newly developed set of estimates for service employment. A sufficient degree of disaggregation, consistency and harmonization was attained by merging existing national sources on employment. The twenty two distinguished service activities are aggregated into four subsectors i.e. producer, distributive, personal and social services. The new evidence revealed that the characteristics of the expansion of services claimed by a number of studies needs adjustment, and for some services the figures of recent years indicate serious changes in trends. In the sixties the growing service employment share was largely due to the expansion of social services. In the seventies and eighties growth in social services slowed down and the expansion of producer services became more prominant. Further, employment growth in personal services started to accelerate in the seventies after substantial declines in the sixties. These changing trends were most pronounced in the United States, but other countries seem to be following the same pattern with some lag.     

ENRICHING WORK ENVIRONMENT IN THE WELFARE SERVICE SECTOR: THE CASE OF SOCIAL ENTERPRISES IN SWEDISH CHILDCARE

Karasak and Theorell's demand/control model for analyzing work environment posits a high degree of both demands and control for active or good working conditions, while stress occurs when demands are plentiful, but there are few possibilities of control. This article addresses a significant increase of work‐related demands for the employees of the public sector in Sweden. It also explores the potential contribution of social enterprises to enrich work environment and provide ‘good work’. The empirical data was taken from two separate studies of work environment at Swedish childcare facilities, one from 1994–95 and another from 2006–07. The article shows that work environment conditions changed radically about 20 years ago and that the effects are still apparent today. The results also show, however, that small, social enterprises continue to offer a better work environment than public facilities.     

INCLUSIVE GOVERNANCE IN SOCIAL ENTERPRISES IN THE NETHERLANDS – A CASE STUDY

An element that policymakers and academics often believe to be constitutive in the governance of a social enterprise is the use of inclusive and responsible decision‐making processes. This entails the involvement of various categories of stakeholders. In this paper, a case study is used to explore how a work integration social enterprise based in the Netherlands, AutiTalent BV, has organized its governance. The Netherlands has not developed legislation specifically dealing with social enterprises, in contrast to many other EU Member States (16 out of 28), and it does not require, although it allows for, the establishment of inclusive governance. By examining how (national Dutch) law affects the governance of a work‐integration‐oriented social enterprise, the authors aim to contribute to emerging theory on participatory and inclusive governance of social enterprises – as a legal concept but also as an organizational concept – shaped by (tailor‐made and/or ordinary) law. The case study reveals that the investigated work integration social enterprise has not set up formal inclusive governance, suggesting that a social enterprise may not be stimulated by legislation which allows but not requires the participation of stakeholders in decision making. At the same time, informal direct communication channels exist between the people who influence the decision‐making processes and people from various stakeholder categories.     

THE RELATIONSHIP BETWEEN CAPITAL STOCK, UNEMPLOYMENT AND WAGES IN NINE EMU COUNTRIES

The focus of this paper is to investigate the importance of the capital stock in the determination of wages and unemployment in a range of EMU countries and to compare the results across countries. A time‐series analysis is conducted in the case of nine euro area countries, which were selected solely on the basis of data availability and consistency: Austria, Belgium, Finland, France, Germany, Italy, Ireland, the Netherlands and Spain. The paper begins with a short review of the literature on capital stock and unemployment, before it deals with the theoretical model. This is followed by estimation and testing of the theoretical model put forward, using both time‐series and panel data. The results are supportive of the main hypothesis of the paper: capital stock is an important determinant of unemployment and wages in the countries considered for the purposes of the paper.
