The results obtained confirm the relative complexity of these causality … relationships, although they generally point to a negative causation running both from concentration to efficiency and from …

The paper empirically analyzes the impact of the degree of efficiency on key performance fig-ures of publicly traded … European banks in the period from 2005 to 2009. Efficiency is meas-ured by constructing non-parametric frontiers using the … technique of data envelopment analysis on the cost, revenue, and profit sides. Decomposition of overall efficiency provides a …

In this paper we discuss cost and profit efficiency on the Colombian financial market in the period 1989-2003, using … stochastic frontier efficiency analysis. During the period, the cost efficient frontier deteriorates, but profit efficient … frontier is relatively stable. We found significant difference when we compare the efficiency scores among different types of …

The results show that the concentration index and the market share have little or no influence … on interest rate margins. In contrast, we produce evidence suggesting that greater efficiency and competitive markets …

This paper examines the … impact of increasing concentration and new technologies, linked with the mergers and acquisitions (M&A) process, on the … degree of competition and technical efficiency of the Polish commercial banks. The goal of this paper is to check whether …

This paper analyzes the relation between bank mergers and changes in the concentration and efficiency of the Venezuelan … Banking System during the period 1998-2005. Efficiency was estimated through a stochastic cost frontier model. The … concentration was measured by deposits and considering the four-firm concentration ratio. The research found evidences that support …
