Quality of service,efficiency and scale in network industries: an analysis of European electricity distribution

Quality of service (QoS) is of major economic significance in natural monopoly infrastructure industries. In this article, we present an efficiency analysis of electricity distribution networks from seven European countries. We apply the stochastic frontier analysis method to multi-output translog input distance function models to estimate cost efficiency and scale economies. We show that introducing the quality dimension into the analysis affects estimated efficiency significantly, especially that smaller utilities’ efficiency seems to decrease. Our results emphasize that QoS should be an integrated part of efficiency and economic analysis of regulated natural monopolies.     

Export diversification in a transitioning economy

How does the process of export diversification take place in an economy in transition, especially in light of government policy aimed at trade liberalization? This article examines this question by considering a directed policy effort by Syria – an economy in transition from both economic centralization and resource dependence – to liberalize its trade between 2001 and 2008. In addition to documenting the patterns of diversification at the aggregate level since the implementation of the policy, we also examine factors that are related to diversification at the sectoral level. Our findings suggest that, while Syria has achieved reasonably rapid export diversification, this may to a large extent be the result of structural transformations in the economy, and that further diversification may require continued policy reform designed to strengthen Syria's weak institutional and business environment.     

Sabotage in Tournaments with Heterogeneous Contestants: Empirical Evidence from the Soccer Pitch

In this paper, we address the problem of sabotage in tournaments with heterogeneous contestants. In a first step, we develop a formal model, which yields the prediction that favorites exert higher productive effort, while underdogs are more tempted to engage in destructive actions (sabotage). This is because favorites have a higher return on productive effort and both types of effort are substitutes. In a second step, we use data from German professional soccer to test this prediction. In line with the model, we find that favorite teams win more tackles in a fair way, while underdog teams commit more fouls.     

On the growth and welfare effects of monopolistic distortions

The most fundamental proposition about growth and competition is that there is a tradeoff between static welfare and long-term growth. This paper reconsiders this basic proposition in an expanding variety endogenous growth model with competitive markets for “old” innovative products and for a traditional good. We shed light on some implications of monopolistic distortions which tend to be ignored by standard models. First, no growth may be better than some growth, since modest positive growth potentially requires sizeable static welfare losses. Second, the economy may converge to a steady state with zero growth, even though a locally saddle-point stable steady state with positive growth exists if the initial share of “cheap” competitive markets is sufficiently high, as this implies a relatively low demand for “expensive” innovative goods. Third, such a “no-growth trap” may happen in a world economy made up of several countries engaged in free trade with each other. The policy implications are that growth-enhancing policies may be misguided and that quick deregulation as well as quick trade liberalization can lead to stagnation in the long term.      

Contest success functions: an extension

Summary. This note extends the axiomatic characterization of the power success function in fair contests by Skaperdas (1996) to an unfair contest. We show that the results previously obtained are straightforward to generalize; the success function is uniquely characterized by Luces Choice Axiom (implying independence of irrelevant alternatives) and homogeneity of degree zero.Received: July 1, 1996; revised version: October 30, 1996This revised version was published online in February 2005 with corrections to the cover date.     

Value added,wages and labour market flows at the establishment level

In this article, we analyse the connection between value added, wages and labour market flows at the establishment level. We develop a simple model to illustrate the expected comovement of these variables. For the empirical analysis, we link the new German Administrative Wage and Labor Market Flow Panel data set to the IAB Establishment Panel. We show that establishments’ hires rates have a positive and separations rates a negative comovement with establishment-specific value added, whereby hires react by more than separations. In addition, we provide evidence that establishments’ partial equilibrium reaction is an important driver for aggregate labour market dynamics.
