The Consolidation of the Financial Services Industry: Causes, Consequences, and Implications for the Future

This article designs a framework for evaluating the causes, consequences, and future implications of financial services industry consolidation, reviews the extant research literature within the context of this framework (over 250 references), and suggests fruitful avenues for future research. The evidence is consistent with increases in market power from some types of consolidation; improvements in profit efficiency and diversification of risks, but little or no cost efficiency improvements on average; relatively little effect on the availability of services to small customers; potential improvements in payments system efficiency; and potential costs on the financial system from increasing systemic risk or expanding the financial safety net.

Agency Problems and Risk Taking At Banks

The moral hazard problem associated with deposit insurance generates the potential for excessive risk taking on the part of bank owners. The banking literature identifies franchise value -- a firm’s profit-generating potential -- as one force mitigating that risk taking. We argue that in the presence of owner/manager agency problems, managerial risk aversion may also offset the excessive risk taking that stems from moral hazard. Empirical models of bank risk tend to focus either on the disciplinary role of franchise value or on owner/manager agency problems. We estimate a unified model and find that both franchise value and ownership structure affect risk at banks. More important, we identify an interesting interaction effect: The relationship between ownership structure and risk is significant only at low franchise value banks -- those where moral hazard problems are most severe and where conflicts between owner and manager risk preferences are therefore strongest. Risk is lower at banks with no insider holdings, but among other banks, there is no relationship between the level of insider holdings and risk. This suggests that the owner/manager agency problem affects the choice of risk for only a small number of banks -- those with low franchise value and no insider holdings. Most of these banks increase their insider holdings within a year, and these changes in ownership structure are associated with increased risk. This suggests that owner/manager agency problems are quickly addressed.

Looking Beyond the CEO: Executive Compensation at Banks

The literature on executive compensation at banks has proceeded largely under the assumption that a single elasticity can adequately describe the sensitivity of executive pay to firm performance, but theories of performance based pay and tournament pay suggest that this assumption may be incorrect. We test the single-elasticity assumption by comparing the components of compensation and the pay-performance relationship across banks with different characteristics and bank executives of different positions. We find that the structure of compensation varies significantly across firms, with firm size being an important explanatory firm characteristic. The structure of compensation also varies across executive positions, but only after controlling for differences across firms. These patterns translate into significant differences in pay-performance relationships across firms, with size being the distinguishing firm characteristic. Differences across executives are less robust. There is some evidence that CEO stature enhances pay-performance sensitivity at the largest banks in our sample, but the non-base pay components of CEO compensation are apparently less performance sensitive than their labels would suggest.

Human Resource Needs in the Evolving Financial Sector

As banks, securities houses, and insurance companies offer increasingly similar services, how have their human resource needs changed? An analysis of survey data reveals that all three industries have come to rely more heavily on high-skilled labor; however, the educational and occupational profiles of their workforces have not become substantially more alike.
