The use of the scaling property in a frontier analysis of a system of equations

ABSTRACT

This article presents a one-stage efficiency frontier analysis based on the scaling property. This type of analysis is a not very often applied in empirical work in spite of its nice features. Due to the scaling property the influence of exogenous (managerial) variables on efficiency can be modelled and estimated in one stage. It also opens the possibility of estimating a system of equations, consisting of a cost function and the corresponding cost share equations. The model is applied to a unique data set of Dutch secondary education school boards in the period 2007–10, not only consisting of regular data on cost, inputs and outputs, but also of specific data on operational management. The model provides reliable and plausible estimates for the cost efficiency, scale elasticity, and technical change. Average cost efficiency is about 96%. Economies of scale prevail for school boards with size less than 0.8 times average size, whereas annual productivity growth is 2.2% on average.     

U.S. Welfare Reform: What's Relevant for Europe?

This paper reviews the U.S. welfare reform efforts over the1990s and the effects of these reforms to date. Seven "lessons"of potential interest to European observers are discussed, withparticular attention to the conclusions of more recent research.Such research indicates, for example, that more effective programscontain both positive and negative incentives, utilise work-firstas well as job training programs, and provide some importantsupports beyond just job and work skills. The paper ends withsome speculations about why European policy-makers are becomingmore interested in U.S. welfare reform experiments than theyhave been in the past. (JEL I3, J2, H1)     

Ambiguous professionalism: managing efficiency and service quality in an Israeli call centre

This case study examines the management of frontline employees in an Israeli call centre by focusing on the organisational rhetoric of 'professionalism' and the implementation of integrative human resource practices (debriefing, covert call monitoring, information and technology software, and a monthly bonus). This culture is critically explored as a ceremonial facade that covers the conventional quantity/quality tension.     

Can/Should/Will A Niche Become the Norm? Organic Agriculture's Short Past and Long Future

A theory is proposed that explains the evolution of a market based on a quality variant as it goes from being a niche to the market norm. Organic commodities are described as such a quality variant and used to focus on the economic and policy issues that arise during a market's evolution. It is shown how organic products in general can become the norm in many American commodity markets. However, there is disagreement over whether it should and much uncertainty about whether it will. The current status of two organic markets is discussed to illustrate empirical issues. (JEL Q130, Q110 , Q100 )     

Health and Life Sciences as Drivers for Regional Development and Prosperity in the Baltic Sea Region

This article describes the role of health and life sciences as drivers for regional development and prosperity in the Baltic Sea Region. The rapid development of new technologies in combination with steadily increasing data mining capabilities revolutionizes prediction, prevention, and treatment of illnesses. Together with the demographic change, this will challenge the sustainability of regional and national health systems across the BSR. Furthermore, globalization potentially leads to major threats to the health of citizens by pandemic incidents. Due to their dimension and the fragmentation of health care systems and markets, these challenges can be met only with new, multidimensional, cross-sectoral, and innovative approaches involving a broad range of actors and stakeholders. Furthermore, there is a growing need to incorporate health concerns and innovation issues into all policy levels. For the Baltic Sea Region this is both a challenge and an economic opportunity.     

Concavity assumptions in regulatory models and the capital waste controversy

Sherman (1992, 197) concludes that the wasteful use of capital [by a rate-of-return constrained monopolist] is motivated to avoid an inelastic region of demand. Previous analyses of capital waste by regulated firms often employ models with concavity restrictions on the profit and production functions. Here we demonstrate that these conventional assumptions in Averch-Johnson type models require demand to be everywhere elastic, ruling out the avoidance motive emphasized by Sherman. Although these highly restrictive assumptions are suitable for studying inefficient input mix, they are inappropriate when considering investment in unproductive capital.This note is based on the appendix to my doctoral dissertation completed at The University of Tennessee, Knoxville, and supervised by John W. Mayo. Useful comments were also made by Ross Eriksson of The University of Tennessee, David Kaserman of Auburn University, David Mandy of the University of Missouri, and an anonymous referee.

On the efficiency of fair trade

The first part of this paper reviews five major theoretical approaches that describe the fundamental causes of poverty, with particular attention to what these theories imply about government policy towards markets and the need for immediate poverty alleviation. Different causal theories have very different policy implications; it is difficult to recommend specific anti-poverty policies with making assumptions about the nature of economic markets and of individual behavior. The paper ends with comments about how to make these choices, arguing that the greater moral onus one associates with poverty, the more willing one should be to adopt less efficient strategies that do more to raise incomes among the poor. The interconnections between markets and social and political systems—which often disadvantage poor populations—suggests that some market regulations and targeted programs may be necessary to reduce poverty, especially if these can be implemented with minimal corruption and monitored for effectiveness.
