THE ROLE OF MICRODATA IN THE NATIONAL ECONOMIC AND SOCIAL ACCOUNTS*

Microdata sets—samples of data relating to individual reporting units—can provide a valuable extension of the national economic accounts as they presently exist, making it possible to meet many of the criticisms being leveled at the accounts over their failure to include much nontransactions information that is essential to the evaluation of economic and social performance. To serve this purpose, however, the microdata sets must be integrated with the aggregate accounts, and with one another. A microdata sets relating to any given sector should add up (with appropriate weighting) to the economic constructs for that sector in the national accounts, and the microdata set for one sector should be articulated as appropriate with those of other sectors. This paper discusses techniques for constructing such microdata sets, including necessary adjustments of the macro accounts, techniques of alignment of microdata with the macro accounts and the creation and development of synthetic microdata sets. Synthetic matching and other techniques of merging data sets are discussed. The paper concludes with a consideration of the methodological implication of the integration of microdata and national accounts.     

CLASSIFICATION PROBLEMS AND THE DIVIDING LINE BETWEEN GOVERNMENT AND THE MARKET: AN EXAMINATION OF NHS FOUNDATION TRUST CLASSIFICATION IN THE UK

ABSTRACT: In this paper we argue that national accounting categories provide an inadequate basis for evaluating differences between public and private sector services. This is because accounting categories rely on economic concepts such as market price but do not take account of substantive public policy goals such as universality. The argument has important consequences for the structures and systems of delivery especially where nonprofit providers and social enterprise models are substituted for public bodies formerly integrated into the government's delivery system. Using an example taken from the UK's National Health Service, we show that the mechanisms for ensuring universality through redistribution are not sufficiently taken into account for classification purposes.     

THE UNITED NATIONS SYSTEM OF NATIONAL ACCOUNTS IN THE MIDDLE EAST

After an introduction setting out the general state of work on the national accounts in the Middle East the author considers the principal uses of national accounts statistics in less developed countries. The first group of uses discussed is in connexion with the measurement of growth and the making of international comparisons. The author is of the opinion that in many cases the primary statistical series are so weak that the fact they they are combined together into a series called national income or gross domestic product lends to them a significance which they do not really possess. The real problem is to improve the quality of the primary series. A second use of national accounts statistics is in connexion with fiscal and budgetary policy. In the statistically advanced countries this is one of the most important uses but in the less developed countries budgetary policy has not yet reached a level of sophistication which would call for the use of national accounts data. Moreover, the time factor involved in assembling accurate national accounts estimates militates against their effective use for short term forecasting. The author considers that the most important use for national accounts statistics is to provide a framework for development planning. The United Nations system is not altogether appropriate for this purpose. It grew up primarily as a system for recording income flows but in development planning one is concerned equally with commodity flows with a great deal of attention being focussed upon intermediate products. The proposals of the working group of African Statisticians for an adaptation of the S.N.A. to African countries represents a most important advance in this respect. In the final section of the paper the author advocates a broader definition of capital formation to include developmental expenditure which is not properly defined as fixed capital formation. Education expenditure is cited as an example. It is suggested that in the national accounts it would be desirable to operate with gross concepts. However, the growth of the capital stock is obviously important in less developed countries and it is suggested that statistical techniques be devised to measure it directly wherever possible. Finally, attention is drawn to the ambiguities and weaknesses in the concept of residence as used at present in the S.N.A.     

ON THE EMERGENCE OF NON‐PROFIT FIRMS AS ALTERNATIVES TO THE GOVERNMENT*

It is well known that many non‐profit firms coexist with government firms in industries that provide collectively consumed goods and services, such as education, healthcare, social services, and art and culture. This paper explores the specific circumstances under which non‐profit firms can emerge as alternatives to the government. We show that a non‐profit firm emerges only when the residents’ median preference for a collective good is significantly low. This finding implies that, somewhat paradoxically, a non‐profit firm emerges to replace the government and provide a collective good only when the majority of residents consider the good non‐essential.     

A COMPARISON OF PERFORMANCE INDICATORS FOR TRAINING AND ENTERPRISE COUNCILS IN THE UK

ABSTRACT ** : The use of performance indicators for the evaluation and comparison of efficiency in service provision in the public and related sectors of the economy is continuously developing. While they often represent a step forward, to the extent that they focus attention on the objectives of the organization in question, it is frequently suspected that they fail to take into account non-controllable environmental factors. To do so requires multivariate techniques of analysis. This paper compares the results of three such methods with the raw performance indicators. It confirms the importance of non-controllable factors but also shows that different multivariate methods give results which do not always agree. Understanding the properties of different approaches is essential in drawing conclusions about performance.

ADJUSTING NET WORTH FOR PRICE CHANGES WITH REFERENCE TO THE CANADIAN SYSTEM OF NATIONAL ACCOUNTS

This paper develops a rationale for a comprehensive measure of income and provides illustrative calculations within the Canadian System of National Accounts for making adjustments to net worth for price changes.
The paper notes that the System of National Accounts is designed to provide a number of individual aggregates measuring total production, income, savings and net worth. There is no single overall comprehensive measure which reflects the combined effect of changes in income and wealth. Such a measure is of particular importance in periods of rapid or extensive price changes which affect not only purchasing power of income but also the value of assets held and liabilities outstanding with consequences on net worth positions. This paper explores these issues and develops techniques for measuring the effects of specific and overall price changes with respect to net worth of the various sectors in the economy, illustrated with data from the integrated Canadian System of National Accounts.     

EFFECTIVE DEMAND, OUTWARD INVESTMENT AND THE (THEORY OF THE) TRANSNATIONAL CORPORATION: AN EMPRICAL INVESTIGATION

That demand-side deficiencies can provide an inducement for outward investment by transnational corporations has never acquired much currency, despite its long history and the fact that existing theories ofter have implications supportive of it. Arguably a reason for this is that the idea has never been tested empirically. In this paper we provide the first such empirical test. First we critically survey and attempt to synthesize the mainstream microeconomic or supply-side theories of the TNC. Then we examine the case for a demand-side perspective, link this to the supply-side and discuss some existing indirect evidence in support of this perspective. Finally we provide a direct econometric test of the demand-side perspective, which provides clear support for it.     

THE RESEARCH ASSESSMENT EXERCISE AND THE REFORM OF ACADEMIC TENURE IN THE UNITED KINGDOM

In this article the reform of academic tenure is examined in the United Kingdom. We test the hypothesis that reforming tenure may have reduced performance in the universities. The years following the 1988 Education Reform Act provide an interesting natural experiment, as the broad effect of the legislation was to soften (though not to remove) tenure in universities in the United Kingdom. It is concluded that the act has not adversely affected efficiency as some writers have predicted it would.     

HOUSEWORK VS. MARKETWORK: SOME EVIDENCE HOW THE DECISION IS MADE

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.

THE MEASUREMENT OF PRODUCTIVITY AND MARKET STRUCTURE IN THE UK

This paper explains how the Solow residual should be adjusted to provide a correct measure of productivity when markets are not perfectly competitive. Although the null hypothesis of a unity markup coefficient can not be rejected, values greater than one also lie within the confidence interval. Hence the adjustment for imperfect competition should be carried out. The finding that the average mark-up coefficient in the UK is lower than in the US might reflect the higher degree of intra-EC import competition.     

THE (NON)THEORY OF THE KNOWLEDGE FIRM

This paper argues that the mainstream approaches to the theory of the firm do not provide a theory of the human capital‐based or knowledge firm. We examine the neoclassical theory of the firm, the transaction cost model, the incentive‐system approach and the Grossman Hart Moore approach and argue that none of them is able to fully capture the changes to the firm that the movement towards a knowledge economy entails. We also consider the effects of knowledge on the organisation of production. Will production take place within a single large factory, or several smaller factories or even within households?     

THE AGGREGATE DEMAND FOR LABOUR IN AUSTRALIA: A META-ANALYSIS*

In this paper, meta-analysis techniques are applied to 34 studies of the aggregate demand for Australian labour. Inverse associations between the real wage and employment and demand and unemployment are established, and positive associations between demand and employment and the real wage and unemployment are established. The associations are stronger with respect to the real wage. The results suggest that at least two-thirds of the variation in estimates across studies is artifactual and is due to specification differences. It is argued in this paper that the available studies are of limited value to policy formulation. No single empirical study can provide definitive measures of a particular parameter. This guarantees that substantial numbers of empirical studies of the more important parameters describing labor demand will have been produced. (Hamermesh, 1993, p. 61)     

SERVICES INDUSTRIES IN THE BUSINESS SECTOR OF THE CANADIAN ECONOMY

The focus of this paper is an examination of concepts and statistics necessary to support the measurement of real output of services industries. Although applied to the business sector of the Canadian economy, the issues raised may in fact be relevant for many other countries. The Canadian practice is judged with reference to the international guidelines and recommendations. General methodological issues of deflation are examined, particularly double deflation, extrapolation and rebasing. The perennial problems such as the deflation of imputed banking services, insurance, trade margins, etc. are analysed with a view to provide some tentative solutions thereof. Quality assessment of statistics and the criteria used for such an assessment are indicated to share our concern with the international colleagues facing similar problems.     

ESTIMATES OF THE HIDDEN ECONOMY IN AUSTRIA ON THE BASIS OF OFFICIAL STATISTICS

By definition, the hidden economy eludes straight observation by means of official statistics. Nevertheless, attempts to quantify these phenomena usually make reference to official materials in various respects, e.g. as regards definition, or when evaluating the relative importance or some indirect reflections of such activities. In this context, official statistics may serve as a particularly useful reference when those sections of the economy are concerned which are hardly or not at all susceptible to hidden activities. Such sections can be identified in terms of industry and in terms of occupation.
In the present investigation such techniques have been used to a large extent and only official statistics have been drawn upon as a data source. Accordingly, the outcome matches closely with national accounts concepts and existing national classifications of various socio-economic statistics. The estimates refer to the hidden ("off the records") activities of the self-employed as well as to similar activities of employees, the unemployed etc. ("moonlighting"). Per se criminal activities have not been included, however. As regards the self-employed the estimates basically rely on income differentials observed between small scale entrepreneurs and their employees. As regards employees numbers employed of various preselected occupational categories and of some additional groups of non-employed have been processed successively, matching them e.g. with comparable data on time budgets and regional frequency.
The outcome largely confirms common experience or expectations as regards the fields where hidden activities assume significant relative importance whereas the overall size of the hidden economy turned out fairly small as compared with official GDP.     

The measurement of technical efficiency: a neural network approach

The main purpose of this paper is to provide an introduction to artificial neural networks (ANNs) and to review their applications in efficiency analysis. Finally, a comparison of efficiency techniques in a non-linear production function is carried out. The results suggest that ANNs are a promising alternative to traditional approaches, econometric models and non-parametric methods such as data envelopment analysis, to fit production functions and measure efficiency under non-linear contexts.     

Bootstrapping regression estimators under first-order serial correlation

It is well known that with highly trended time series data and strongly autocorrelated disturbances, there will be a marked tendency for standard GLS techniques to over-reject true null hypothesis in finite samples. There is also a potential problem because most applications of GLS are in conjunction with a pretest such as a Durbin-Watson test. An application of bootstrapping to these problems is considered here using a small Monte Carlo experiment; the results provide no evidence that standard bootstrapping provides an improvement.     

TRUST, INEQUALITY AND THE SIZE OF THE CO-OPERATIVE SECTOR: CROSS-COUNTRY EVIDENCE

ABSTRACT:  We provide the first empirical evidence on the determinants of differences in the size of the cooperative sector around the world. Our key data have been recently released by the ICA and are integrated with other standard sources, such as data from the World Values surveys. In our empirical work we concentrate on the links between inequality and trust and cooperative incidence and undertake selectivity correction estimates as well as a series of robustness checks. Consistent with theory we find strong support for the proposition that trust plays a causal role in accounting for differences in co-operative incidence. Also consistent with theory, we find support (albeit much weaker) for the role of inequality. Further support for our findings flows from our estimates for conventional, listed firms, where we do not find that trust and inequality play similar roles in accounting for the variation in the incidence of large listed firms across countries.     

THE FOCAL POINT IN THE TRAVELLER'S DILEMMA: AN EXPERIMENTAL STUDY

This paper provides an experimental test of the traveller's dilemma. Our investigation aims to address the research hypothesis that introducing a reference point à la Schelling (set equal to the Pareto optimal solution) might drive people away from rationality even when the size of the penalty/reward is high. Experimental findings reported in this paper provide answers to this question showing that the reference point did not encourage coordination around the Pareto optimal choice.
