In many countries consolidation in the banking industry has reduced the number of small banks and led to significant shifts in market shares; deregulation has fostered entry in local credit markets and the expansion of branch networks, increasing competition in local markets. Small businesses are believed to be more vulnerable to these changes, since they are more dependent on credit from local banks. In this paper we investigate the consequences of consolidation and entry for these borrowers compared with those for large firms. We employ a data set for Italy, which provides information on volumes of loans and bad loans by size of borrower with a detailed geographical partition. We find that mergers are followed by a temporary reduction in outstanding credit to all sizes of borrowers and by an increase in bad loans, most likely due to the reassessment of banks portfolios. Entry has a relatively persistent negative impact on credit supply to small and medium-sized firms. Our results also show that concentration, branch density and the share of branches of small banks affect the volumes of credit and bad loans of small borrowers.

Corporate governance theory predicts that leverage affects agency costs and thereby influences firm performance. We propose a new approach to test this theory using profit efficiency, or how close a firm’s profits are to the benchmark of a best-practice firm facing the same exogenous conditions. We are also the first to employ a simultaneous-equations model that accounts for reverse causality from performance to capital structure. We find that data on the US banking industry are consistent with the theory, and the results are statistically significant, economically significant, and robust.

The Pakistani banking system has been transformed over the past 15 years through liberalization, the entry of private banks, the privatization of public-sector banks, and the tightening of prudential regulations. The effects of these changes on bank productivity and relative efficiency are investigated using various techniques. Bank productivity in terms of profits has increased, and new entrants have been efficient, but the dispersion of efficiency remains wide. The privatized banks improved their profit efficiency in the period immediately following their privatization, but in the subsequent years only one significantly improved its efficiency, whereas the other did not differentiate itself in terms of efficiency from the remaining state-owned banks. The new private domestic banks generally proved to be among the most efficient, and sometimes out-performed the foreign banks.
