This paper uses stochastic frontier analysis to provide international evidence on the impact of the regulatory and supervision framework on bank efficiency. Our dataset consists of 2,853 observations from 615 publicly quoted commercial banks operating in 74 countries during the period 2000-2004. We investigate the impact of regulations related to the three pillars of Basel II (i.e. capital adequacy requirements, official supervisory power, and market discipline mechanisms), as well as restrictions on bank activities, on cost and profit efficiency of banks, while controlling for other countryspecific characteristics. Our results suggest that banking regulations that enhance market discipline and empower the supervisory power of the authorities increase both cost and profit efficiency of banks. In contrast, stricter capital requirements improve cost efficiency but reduce profit efficiency, while restrictions on bank activities have the opposite effect, reducing cost efficiency but improving profit efficiency.

We investigate the determinants of commercial bank acquisitions in the former fifteen countries of the European Union by evaluating the impact of bank-specific measures, such as size, growth and efficiency of banks, and external influences reflecting industry level differences in the regulatory and supervision framework, market environment and economic conditions. Our empirical analysis involves multinomial logit estimation at various levels in order to identify those characteristics that most consistently predict targets and acquirers from a sample of over 1400 commercial banks. The overall results indicate that, relative to banks that were not involved in the acquisitions, (i) targets and acquirers were significantly larger, less well capitalized and less cost efficient, (ii) targets were less profitable with lower growth prospects, and acquirers more profitable with higher growth prospects, (iii) external factors have affected targets and acquirers differently, and their effects have not been consistent or robust to sample size changes.

ABSTRACTThis paper assesses the interrelationship between financial openness, bank risk and bank profit efficiency using a cross-country sample of 2,007 commercial banks covering 140 countries over the period 1999-2011. To establish whether the impact of financial openness on both bank risk and profit efficiency occurs directly or through each one of the two bank characteristics (efficiency and risk, respectively), we begin our analysis by investigating the potential reverse Granger causality between profit efficiency and risk using a dynamic simultaneous model via system GMM estimation. We then account explicitly for the role of bank risk in the estimation of bank profit efficiency using stochastic frontier analysis, allowing for the influence of different measures of financial openness and risk alongside other control variables. Our results indicate that financial openness reduces bank profit efficiency directly, not through changes in bank risk. We also find that financial openness increases bank risk indirectly, through the decreased bank profit efficiency channel. JEL Classification: G21; F36; C23; C24

We examine a sample of 17 banking institutions operating in the UK between 2001 and 2006 to provide empirical evidence on the association between the efficiency of UK banks and board structure, namely board size and composition. Our approach is to use data envelopment analysis to estimate several measures of the efficiency of banks, and then to use panel data regressions for investigating the impact of board structure on efficiency. After controlling for bank size and capital strength, we find some evidence of a positive association between board size and efficiency, although this is not robust across all our specifications. Board composition, by contrast, has a robustly significant and positive impact on all measures of efficiency. © 2011 Copyright International Journal of the Economics of Business
