ASSESSING THE ASSESSMENT OR,THE RAE AND THE OPTIMAL ORGANIZATION OF UNIVERSITY RESEARCH

The UK Research Assessment Exercise (RAE) is assessed as an incentive scheme affecting the allocation of research talent of varying ‘quality’ across departments. The ‘centres of excellence’ policy implicitly pursued through the RAE is an optimal allocation strategy only if all departments in all disciplines are of the generalist variety, i.e. each pursues a research path through all its stages. Conversely, the RAE‐induced research allocation minimizes efficiency if applied to specialist departments, when resources are concentrated on one specific research obstacle. It is argued that the RAE should not take the organization of University research as exogenous, but rather should encourage specialization. All results are obtained by applying to University research concepts and solutions borrowed from the mathematical theory of systems reliability.     

SOCIAL INDICATORS—SYSTEMS, METHODS AND PROBLEMS

Professor Moser regards the purpose of social indicators as being to aid the policy maker by summarizing the state and changing conditions of society, pinpointing the outstanding existing and emerging social problems and monitoring the effects of social policies and programmes. Thus social indicators will frequently, though not necessarily, be normative and they will often, though again not necessarily, be concerned with outputs rather than inputs. Although many writers regard social indicators as being combinations of series, the problems of construction are substantial. Central to the idea of a social indicator, however, is that it should represent or summarize a broader concept than itself and that it should belong to a structure or system of series. Although there are no social theories about society in general on which a structure of indicators can at present be based there are a number of middle range theories relating to specific fields or sectors, such as occupational mobility, education, migration, mental health, etc., around which quantitative relationships and models can gradually be be built to give insight into social changes and perhaps eventually into the manipulation of policy instruments for the improvement of social conditions.

Imposing monotonicity on outputs in parametric distance function estimations

The technology set involved in the estimation of a multi-output production frontier theoretically implies monotonicity on outputs. This is because an efficient firm cannot reduce the vector of outputs holding the vector of inputs fixed while it still belongs to the frontier. In empirical studies dealing with the estimation of parametric distance functions, this hypothesis is often violated by observations with far from average characteristics. To overcome this limitation, we propose a new approach for allowing the easy imposition of monotonicity on outputs in this context. This methodology is tested in the educational sector using Spanish student level data from the Programme for International Student Assessment (PISA) database. The results indicate that a nonnegligible 8.33% of the production units break the monotonicity assumption. Furthermore, although there is no statistically significant difference in efficiency distribution by school ownership, our methodology helps to detect a slight worse mathematical performance for students attending public schools.     

Justifying the incorporation of the materials balance principle into frontier-based eco-efficiency models

Frontier-based models are an alternative to traditional eco-efficiency ratio indicators. This paper considers two different types, environmentally adjusted production efficiency models and frontier eco-efficiency models, and tries to find justification for incorporating the materials balance principle (MBP) in them. Similar importance is attached to the economic and environmental outcomes of a production process. Like economic outcomes can be derived from inputs and outputs and respective prices, some cases allow for deriving environmental outcomes from the production function with the MBP. After an overview of attempts to incorporate environmental issues in production efficiency models and some reflections why MBP has been neglected in environmental economics and production efficiency analysis, the paper gives basic principles to incorporate the MBP in conventional production efficiency methods and shows how this adjustment leads to a more diversified diagnosis of eco-efficiency. Finally, potentialities and bottlenecks are discussed. Exploiting the MBP in production efficiency and eco-efficiency analysis will facilitate more pro-active eco-efficiency research.     

The softness of medical production and implications for specifying hospital outputs

This paper considers the implications of an inarticulate medical production function when specifying and interpreting estimated hospital production functions. Lack of scientific knowledge regarding the relationship between medical inputs and outputs results in variations in styles of care, and medical payment contains inefficient production incentives. These production distortions are implicit in reported hospital data. Empirical results of this study provide information regarding the extent and direction of bias resulting from estimating production functions using reported outputs under retrospective cost-reimbursement.     

SERVICE QUALITY IN ELECTRICITY DISTRIBUTION IN BRAZIL: A MALMQUIST APPROACH

The paper undertakes a dynamic analysis for service quality in the electricity distribution in Brazil between 2010 and 2014 based on Malmquist indexes constructed upon Data Envelopment Analysis (DEA) distance functions. The motivation for the less usual consideration of efficiency frontiers for service quality, that does not rely on traditional inputs and outputs but rather on quality indicators, builds on previous static applications in the context of telecommunications. The analysis considers undesirable technical indicators for quality as inputs and desirable consumer satisfaction indicators for quality as outputs in the efficiency frontier analysis. The bootstrap‐corrected Malmquist indexes indicated service quality deterioration in 38.1 per cent, quality stagnation in 40.5 per cent and quality improvement only in 21.4 per cent of the cases. When one decomposes the Malmquist index, the evidence does not suggest relevant frontier shifts and indicates a dominant role for the catch‐up effect. Finally, Malmquist indexes are regressed against variables that may portray heterogeneities, such as firm size, service area, density, ownership and regional dummies in terms of a well‐known two‐stage procedure. The mostly weak significance results reinforce the plausibility of the initial analysis.     

FILES OF INDIVIDUAL DATA AND THEIR POTENTIALS FOR SOCIAL RESEARCH

In a statistical file system, data collected from different sources and at different dates are stored at an individual unit level. Thus, they may be linked and used for the preparation of statistics and for analytical purposes as the need arises. The statistical file system will provide a much improved data basis for empirical research in the social services including demography, economics, economic geography, sociology, education, labour, social medicine, criminology and social psychology.     

Economics research in Canada: a long-run assessment of journal publications

Abstract.  We examine the publications of authors affiliated with an economics research institution in Canada in (1) the Top-10 journals in economics according to journals' impact factors, and (2) the Canadian Journal of Economics . We consider all publications in the even years from 1980 to 2000. Canadian economists contributed about 5% of publications in the Top-10 journals and about 55% of publications in the Canadian Journal of Economics over this period. We identify the most active research centres and identify trends in their relative outputs over time. Those research centres successful in publishing in the Top-10 journals are found to also dominate the Canadian Journal of Economics . Additionally, we check the robustness of our findings with respect to journal selection, and we present data on authors' PhD origin, thereby indicating output and its concentration in graduate education.     

Using panel data analysis to estimate confidence intervals for the DEA efficiency of individual decision making units

This article demonstrates a methodology using panel data analysis to estimate confidence intervals for the data envelopment analysis efficiency of individual decision making units (DMUs), and the statistical significance of trends in individual DMU efficiency. The procedure accounts for stochastic variations of the inputs and outputs of the target DMU as well as stochastic variations of the inputs and outputs of its efficient benchmark peers. The procedure is demonstrated using 9 years of data from 34 Canadian paratransit agencies.     

Social Constructs and their Usefulness in Original Institutionalist Research: Quality Matters

Some institutionalist researchers are reluctant to use quantitative methods, possibly limiting the extent and influence of institutional research. Social indicators may provide useful inputs into institutionalist analyses, but caution is warranted. This article discusses the importance of exploring a social indicator’s quality before adopting it as a research input.     

Re-evaluation of global innovation index based on a structural equation model

The Global Innovation Index (GII) was proposed to observe the innovation capability and efficiency levels of individual countries using input and output factors. However, it does not consider potential structural relationships among factors affecting the innovation performance of a country. In this study, we proposed a structural equation model (SEM) based on the hypothesised national innovation structure among seven factors representing inputs (institution, human capital and research, infrastructure, market sophistication, and business sophistication) and outputs (knowledge and technology outputs, and creative outputs). Using GII data from 2013, we discovered that business sophistication and infrastructure have the strongest direct and indirect effects on creative output, respectively. In addition, a new ranking is obtained based on the fitted SEM. We provide feedback information to improve innovation capabilities.     

Employment Effects of Product and Process Innovation in Europe

This paper develops a model of the employment impact of innovation considering, on the one hand, the interactions with demand and labour costs and, on the other, the variety of patterns of technological change. Different technological strategies are considered. First, a search for technological competitiveness is based on product innovation and productivity rooted in quality advantages; second a strategy of active price competitiveness has productivity growth rooted in process innovation-based restructuring; third a passive price competitiveness strategy is pursued by non-innovators relying on cost-cutting. The new European innovation database drawn from the Community Innovation Survey 1994-96, merged with structural and macroeconomic data 1994-99 drawn from the OECD are analysed at a sectoral level across eight European countries: Italy, France, Germany, Denmark, Netherlands, Finland, the UK, and Sweden. The innovation survey data provide information on several quantitative and qualitative aspects of firms' innovative activities. A comparison of the results from the first (1990-92) and second (1994-96) Community innovation survey data is also carried out. The results show that, in the last decade, technological change has had a major impact on employment in manufacturing industry, associated with the dominance of an active price competitiveness strategy.

The competitiveness of the UK aerospace industry

Porter's five competitive forces model provides an analytical framework for assessing the UK aerospace industry's competitiveness in this article. Various statistical indicators are used to measure competitiveness, based on published data at the industry and firm level, supplemented with information from company interviews. The indicators include productivity, output, firm size, development time-scales, labour hoarding, exports and profitability. The empirical results of this article suggest that, over the period 1980 to 2000, the UK aerospace industry improved its competitiveness compared with the USA and the EU.     

The Value of Advanced Interdisciplinary Classes for Students of Economics: Case Study of a 300-Level Class on Gender in the Economy

Interdisciplinary classes are valuable to students of economics for many reasons. This paper discusses three reasons why such classes, at an advanced level, are useful and important for students of economics. First, interdisciplinary classes have the potential to encourage theory building and critical thinking, especially through the use of primary sources. Second, interdisciplinary classes also provide students with a richer empirical understanding of the world, beyond the narrowly quantitative data used in most economics research. Fostering a ‘constructivist’ view of data, this facilitates future economists building the tools to tell marginalized stories. Lastly, interdisciplinary classes can create a diverse learning environment that facilitates peer learning about difficult subjects such as race, class, and gender. A case study of a 300-level class titled Gender in the Economy, in which a diverse group of students from backgrounds in women’s studies, economics, business, and American studies came together to study the economic history of gender, is used to explore such benefits.

Shadow directional distance functions with bads: GMM estimation of optimal directions and efficiencies

Because of its greater flexibility, the directional distance function (DDF) has been employed with increasing frequency to estimate multiple-input and multiple-output production, where inputs and outputs can be good or bad. However, typically researchers make three restrictive assumptions. First, they assume a direction of movement of firm production toward the frontier. Second, they assume that actual quantities of inputs and outputs are allocatively or price efficient. Third, they assume exogeneity of all inputs and all outputs, except for the normalized one. The first contribution of this paper is to include parameters to estimate optimal directions which correspond to the firm’s profit-maximizing (PM) position. The second contribution is to generalize the DDF to a shadow-quantity DDF. This entails adding distortion parameters to each input and output quantity of the DDF, creating shadow quantities. To estimate the shadow quantities and the structural parameters, we form the shadow DDF system, which includes the shadow DDF and all the first-order price equations from the shadow-PM problem. These include prices for bad inputs and bad outputs, where we approximate their missing prices for use in their first-order price equations. The third contribution is that we estimate the shadow DDF system using a Generalized Method of Moments approach, where all variables are potentially endogenous. This approach is simpler than the Bayesian one employed in Atkinson et al. (Estimating efficient production with bad inputs and outputs using latent prices and optimal directions. Working paper, University of Georgia, Athens, 2016), which estimated shadow prices and optimal directions. Using the same data set, both sets of results are qualitatively very similar, although they differ somewhat quantitatively.     

RESEARCH PUBLICATIONS,ECONOMIC GROWTH AND CAUSALITY: JAPAN'S EXPERIENCE

Based on page counts of articles published in 60 quality economics journals, the role of research publications was examined for Japan. Economic growth is found to have causal effects on research publications. Impulse responses further indicate that economic growth promotes research outputs. A unique socioeconomic characteristic in Japan explains the causal directions found here.
