Competitive viability in banking : Scale, scope, and product mix economies

Conventional scale and scope economies are inadequate to determine the competitive viability of banks that vary in scale and product mix simultaneously. This paper develops two new and more general measures of multi-product economies. Slight diseconomies of scale and product mix are found for banks, usually on the order of 1 to 3 percent, which may be due to demand-side influences. These are robust to differing cost and output specifications, organizational levels, and competitive environments. These results differ from other banking studies that found scope economies, a conflict that may be due to methodological difficulties.     

银行、市场的有效性与稳定性

传统上,金融系统主要有两种形式,一种是以银行为基础的,另一种是以市场为基础的。它们的有效性需要从几个方面来比较,包括风险分担、信息供给、资助新兴产业、法人治理、法律、政治对金融的影响。这两种金融系统各有利弊。就其稳定性来讲,它们都会遭受经济危机的危害。展望未来的金融系统,应该是以金融中介和市场共为基础,具有很多的优点而几乎没有缺陷。     

Educational mismatches versus skill mismatches: effects on wages, job satisfaction, and on-the-job search

Education-job mismatches are reported to have serious effectson wages and other labour market outcomes. Such results areoften cited in support of assignment theory, but can also beexplained by institutional and human capital models. To testthe assignment explanation, we examine the relation betweeneducational mismatches and skill mismatches. In line with earlierresearch, educational mismatches affect wages strongly. Contraryto the assumptions of assignment theory, this effect is notexplained by skill mismatches. Conversely, skill mismatchesare much better predictors of job satisfaction and on-the-jobsearch than are educational mismatches.     

International Comparisons of Banking Efficiency

The banking industry around the globe has been transformed in recent years by unprecedented consolidation and cross‐border activities. However, international consolidation has been considerably less than might have been expected in developed nations—such as long‐term members of the EU—where barriers to entry have been significantly lowered. In contrast, foreign‐owned banks have generally achieved much higher penetration in developing nations. We investigate the extent to which these differences may be related to bank efficiency concerns by reviewing and critiquing over 100 studies that compare bank efficiencies across nations. The studies are in three distinct categories: (1) comparisons of bank efficiencies in different nations based on the use of a common efficient frontier, (2) comparisons of bank efficiencies in different nations using nation‐specific frontiers, and (3) comparisons of efficiencies of foreign‐owned versus domestically owned banks within the same nation using the same nation‐specific frontier. The research—particularly the findings in the third category—is generally consistent with the hypothesis that efficiency differences help to explain the consolidation patterns. The efficiency disadvantages of foreign‐owned banks relative to domestically owned banks tend to outweigh the efficiency advantages in developed nations on average, and this situation is generally reversed in developing nations, with notable exceptions to both findings. We also stress the need for further research in this area.     

The Information Content of Bank Examinations

We identify three types of information from bank examinations—auditing information from verifying the honesty and accuracy of the bank's books, regulatory discipline information about the treatment of the bank by regulators, and private information about bank condition. We estimate these information effects by comparing the cumulative abnormal market returns associated with examinations in which the CAMEL rating remained unchanged, improved, and worsened. All three information effects are found to be greater for banks entering the examination process with unsatisfactory ratings from prior examinations. The only consistently strong effect found is that examination downgrades appear to reveal unfavorable private information about bank condition. The evidence also suggests that the information may reach the market in part through loan quality data released in quarterly financial statements.
