The model of Stiglitz and Weiss ( American Economic Review , 1981, 71(3)) is the seminal analytical work on credit rationing. However, in a recent paper, Arnold and Riley ( American Economic Review , 2009, 99(5)) claim that the distributional assumption on which that model.s main result depends...

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...

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...

We assess the competitiveness of the $400 billion dollar U.S. bank consumer loan market by comparing results from different competition measures-HHI, Lerner Index, H-Statistic along with three others, two of which are related to frontier analysis. These measures are typically weakly related to...

This paper brings to the forefront the assumptions that we make when focussingon a particular type of explanation for bank profitability. We evaluate a broad field of research by introducing a general framework for a profit maximizing bank and demonstrate how different types of models can be...

This paper employs stochastic frontier cost and profit models to estimate economies of scale as well as X-efficiency for multi-billion dollar European and U.S. banks in the period 1995-1999. Empirical results with respect to separate analyses of large European and U.S. banks are strikingly...

In this article, we survey the recent theoretical literature on payment cards and study their implications for public policy. Payment card networks have faced regulatory scrutiny in several countries regarding the setting of various fees including interchange fees fees paid by the merchant's...

In this paper we focus on the assumption of a common efficient frontier when performing an efficiency study for the banking sector. The fact that environmental factors that are not appropriately controlled may easily bias efficiency estimates. First, we estimate a common cost and profit...

This paper is the first detailed and world-wide investigation of the developments in banking competition during the past fifteen years. Using the Panzar-Rosse approach, we establish significant changes over time in the competitiveness of the banking industry. The changes in competition over time...
