    From Transition to Competition: Dynamic Efficiency Analysis of Polish Electricity Distribution Companies

    In this paper, we test the hypothesis that the economic transition toward a market economy increases the efficiency of firms. We study 32 Polish electricity distribution companies between 1997 and 2002, by applying common benchmarking methods to the panel: the non-parametric data envelopment analysis (DEA), the free disposal hull (FDH), and, as a parametric approach, the stochastic frontier analysis ...

    Efficiency Analysis of German Electricity Distribution Utilities: Non-Parametric and Parametric Tests

    This study applies non-parametric and parametric tests to assess the efficiency of electricity distribution companies in Germany. Traditional issues in electricity sector benchmarking are addressed, such as the role of scale effects and optimal utility size, as well as new evidence specific to the situation in Germany. Labour, capital, and peak load capacity are used as inputs, and units sold and the ...

    Regional Differences of Production and Efficiency of Mexican Manufacturing: An Application of Nested and Stochastic Frontier Panel Models

    This study examines the regional divide for Mexican manufacturing. Mexico's north-south disparity is widely noted, but rarely analyzed empirically and at detailed regional level. We use a panel of municipality-level data to estimate regional production functions. An important contribution is the application of nested panel and stochastic frontier models to capture latent regional characteristics and ...

    Finding the Right Yardstick: Regulation under Heterogeneous Environments

    Revenue cap regulation is often combined with systematic benchmarking to reveal the managerial inefficiencies when regulating natural monopolies. One example is the European energy sector, where benchmarking methods are based on actual cost data, which are influenced by managerial inefficiency as well as operational heterogeneity. This paper demonstrates how a conditional nonparametric method, which ...

    Socio-Economic Trends and New Territorial Dynamics in the European Union: Convergence and Agglomeration

    In this study, we explore how general socio-economic trends within the European Union are reflected in the development of different types of regions during the period from 1995 to 2009 and how economic disparities between EU regions change in the course of these processes. Overall, there is a decrease of regional inequalities in terms of per-capita income, but this is mainly the result of catching ...
