This paper results from the research in the framework of the project "Market developments under transition (applied to the petrol and sugar industries)" and its policy implications. A general definition of the problem, the hypothesis and the research methodology are presented in the...

Using a measure of competition based on the Panzar-Rosse model, this paper explains bank competition across 76 countries on the basis of various determinants. Studies explaining banking competition are rare and typically insuffciently robust as they are based on a limited number of countries...

This paper demonstrates that the level of competition in the existing Panzar Rosse (P-R) literature is systematically overestimated and that the tests on both monopoly and perfect competition are distorted. This is due to the use of bank revenues divided by total assets as dependent variable in...

Over the past few decades, the worldwide banking industry has undergone strong consolidation. As a result, the number of banks has fallen sharply. At the same time, the size of the largest banks has increased substantially, both in absolute figures and relative to the size of smaller banks. This...

This paper examines the evolution of a skew distribution of firm sizes from the viewpoint of the 'Bounds' approach to market structure. It confines attention to the role played by non-strategic factors (statistical independence, and cost sideeffects). A model is proposed, which leads to a...

This paper examines the frequency, pervasiveness, and determinants of product switching by US manufacturing firms. We find that one-half of firms alter their mix of five-digit SIC products every five years, that product switching is correlated with both firm- and firm-product attributes, and...

This paper proposes an equilibrium concept for a class of games in which players make irreversible costly decisions; these games have been widely used in the recent I.O. literature. The equilibrium concept is defined, not in the space of strategies, but in the space of (observable) outcomes. It...

This paper uses a difference-in-difference estimator to test whether the introduction of patient choice and hospital competition in the English NHS in January 2006 has prompted hospitals to become more efficient. Efficiency was measured using hospitals’ average length of stay (LOS) for...

This paper reviews the recent literature on game-theoretic models of market structure and their empirical implementation.

This paper traces the time series (?Growth of Firms?) tradition in the study of market structure and looks at how recent studies on entry and the size distribution of firms have modified thinking in this area.
