    Convexity, quality and efficiency in education

    While Data Envelopment Analysis has many attractions as a technique for analysing the efficiency of educational organisations, such as schools and universities, care must be taken in its use whenever its assumption of convexity of the prevailing technology and associated production possibility set may not hold. In particular, if the convexity assumption does not hold, DEA may overstate the scope for improvements in technical efficiency through proportional increases in all educational outputs and understate the importance of improvements in allocative efficiency from changing the educational output mix. The paper therefore examines conditions under which the convexity assumption is not guaranteed, particularly when the performance evaluation includes measures related to the assessed quality of the educational outputs. Under such conditions, there is a need to deploy other educational efficiency tools, including an alternative non-parametric output-orientated technique and a more explicit valuation function for educational outputs, in order to estimate the shape of the efficiency frontier and both technical and allocative efficiency

    Analysing the Research and Teaching Quality Achievement Frontier

    The paper analyses the nature of the achievement possibility frontier between research and teaching quality in higher education under a system of quality evaluation by reference to discrete quality grades. It finds several important reasons why the associated feasible set is likely to be non-convex, and hence where the assumptions of the widely used nonparametric frontier performance analysis technique of Data Envelopment Analysis are no longer valid. The paper therefore investigates the use of the alternative Free Disposal Hull technique, and compares the results of deploying these techniques to the performance evaluation of UK Departments of Economics.Research and teaching quality, Higher education, Departments of Economics, Data Envelopment Analysis (DEA), Free Disposal Hull

    Performance Management and Performance Measurement in the Education Sector

    Get PDF
    The paper examines several outstanding issues on the interface between the measurement of performance in primary and secondary education and the management of improved performance in this nationally important sector. These issues relate to the clarification of the objectives of the education system, the impact of performance reward systems, such as Performance Related Pay, t he role of resources in influencing educational outcomes, the reliability of existing methods of assessing educational performance, such as Data Envelopment Analysis and multivariate regression, and the need for an improved national comparative database if progress is to be made in several of these directions.Performance management; performance measurement; education; data envelopment analysis; quality control; knowledge management.

    Education, earnings, and inequality in Brazil, 1982-98 - implications for education policy

    Get PDF
    The educational attainment of Brazil's labor force, has gradually increased over the past two decades. At the same time, the government has pursued a series of economic structural adjustment policies. The authors investigate how these simultaneous advances have altered the relationship between labor market earnings, and education. They find that the returns to education in the labor market, fundamentally changed between 1982, and 1998. While the returns to tertiary education increased sharply, the returns to primary education dropped by 26 percent, and those to lower secondary, by 35 percent. Moreover, the authors argue, the marginal reduction in wage inequality that occurred in this period was linked primarily to a reduction in the returns to schooling, and only secondarily, to a more equitable distribution of schooling. The findings suggest that the supply of highly skilled labor is inadequate to meet demand. That suggests a need for policy action aimed at increasing access to, and completion of tertiary education. Increasing the supply of highly skilled labor, would improve prospects for both economic growth, and reduce wage inequality.Public Health Promotion,Curriculum&Instruction,Decentralization,Teaching and Learning,Health Monitoring&Evaluation,Teaching and Learning,Curriculum&Instruction,Gender and Education,Health Monitoring&Evaluation,Girls Education

    Lowland farming system inefficiency in Benin (West Africa):

    Get PDF
    This paper uses a directional distance function and a single truncated bootstrap approach to investigate inefficiency of lowland farming systems in the Benin Republic. First, we employed a dual approach to estimate and decompose short-run profit inefficiency of each farming system into pure technical, allocative and scale inefficiency and also into input and output inefficiency. Second, an econometric analysis of factors affecting the inefficiency was generated using a single truncated bootstrap procedure to improve inefficiency analysis statistically and obtain consistent estimates. In the short run, scale, allocative and output inefficiency were found to be the main sources of inefficiency. Based on inefficiency results, the inefficiency of lowland farming systems is the most diverse. Compared to a vegetable farming system, technical inefficiency is significantly higher if farmers switch to a rice farming system. Scale, allocative, output, and input inefficiency are significantly lower with an integrated ricevegetable farming system and there was high prevalence of increasing returns to scale in the integrated rice-vegetable farming system. Water control and lowland farming systems are complements and play a significant role in the level of inefficiency. Input inefficiency shows the difficulty that the producers face in adjusting the quality and quantity of seeds and fertilizers. The paper provides empirical support for efforts to promote an integrated rice-vegetable farming system in West Africa lowlands to increase food security. Keywords Lowlands . Inefficiency .

    The Size and Service Offering Efficiencies of U.S. Hospitals.

    Hospital productivity has been a research topic for over two decades. We expand on this research to include measures of dis/economies of scope. By using the Free Coordination Hull (FCH) we are able to determine if hospitals in our sample can become more efficient if they provide more services (diseconomies of scope) or if two smaller hospitals with a reallocation of resources could become more efficient (economies of scope). Using data from the American Hospital Association for the years 2004-2007, we found variations among hospital markets (measured by the Core Based Statistical Area). We can determine whether dis/economies of scope exist by comparing the results from two linear programming problems. Focusing on four markets: Los Angeles, Philadelphia, Madison, WI, and New Orleans we found variations in how best these hospitals operating in these markets could change in order to increase both scale and scope efficiencies. This approach could be used by policy makers and managers in order to reduce costs by sharing, reducing, or expanding services in hospitals. Findings from a study such as this should aid reform programs by providing more information on the sources of hospital inefficiency.Hospital, Efficiency, Economies of Scope, Hospital Markets

    Research and Development at U.S. Research Universities: An Analysis of Scope Economies

    Get PDF
    This work investigates the presence and sources of economies of scope in R&D at U.S. research universities. The analysis evaluates the tradeoffs and synergies arising between traditional university research outputs (articles and doctorates) and academic patents. We propose a new measure of economies of scope based on a primal representation of the underlying technology. We derive a decomposition of economies of scope which identifies its sources (e.g., complementarity effects and scale effects). Non-parametric estimates of scope economies using R&D input and output data from 92 research universities show significant economies of scope between articles and patents, but modest complementarities.

    This paper investigates the presence and sources of economies of scope in R&D production at U.S. research universities. The analysis evaluates the tradeoffs or synergies arising between traditional university research outputs (articles and doctorates) and a more recent and burgeoning output: academic patents. Using a shortage function, we propose a decomposition of economies of scope (decomposition which includes complementarity effects and scale effects). R&D input and output data from 92 public and private research universities are used to obtain non-parametric estimates of scope economies. The results show significant variations in economies of scope and sources by size and type of university.Research and Development/Tech Change/Emerging Technologies,
