Bank Scale Economies, Mergers, Concentration, and Efficiency: The U.S. Experience

There have been numerous econometric studies of bank scale and scope economies, efficiency, mergers, and market structure and performance in U.S. banking. According to the authors, these studies have come to the following conclusions: Scale: For the very smallest banks, there are scale economies that allow average costs to fall with increases in bank size, but they account for less than 5% of costs. For larger banks, constant average costs or slight diseconomies of scale prevail. Scope: There are at most relatively minor scope economies that reduce cost by 5% or less when multiple products are produced jointly. Revenues appear to be unaffected by product mix. X-Efficiency: Managerial ability to control costs is much more important than scale and scope. Banks may have costs 20% higher than the industry minimum for the same scale and product mix. Mergers: On average, mergers had no significant, predictable effect on cost and efficiency. Market Structure and Bank Performance: Greater local market concentration results in slightly lower deposit rates for small borrowers and slightly higher loan rates for small borrowers. Differences in local market concentration have virtually no effect on bank profitability. The implications of the U.S. experience for Europe are that cross-border mergers and acquisitions by banks in Europe are not like to lower costs by any significant amount. What cost improvements there are will most likely be generated by improvement in X-efficiency, or better management of resources, rather than through improved scale or scope economies. There may be more potential for efficiency gains from mergers on the revenue side than on the cost side, but these have not yet been thoroughly explored. To the degree that cross-border expansions increase local market competition, they may also yield the social benefit of slightly more favorable prices for the consumer of financial services.

The effects of geographic expansion on bank efficiency

We assess the effects of geographic expansion on bank efficiency using cost and profit efficiency for over 7,000 U.S. banks, 1993-1998. We find that parent organizations exercise some control over the efficiency of their affiliates, although this control tends to dissipate with distance to the affiliate. However, on average, distance-related efficiency effects tend to be modest, suggesting that some efficient organizations can overcome any effects of distance. The results imply there may be no particular optimal geographic scope for banking organizations - some may operate efficiently within a single region, while others may operate efficiently on a nationwide or international basis.Bank mergers ; Financial institutions ; Banks and banking - Costs

Explaining the dramatic changes in performance of U.S. banks: technological change, deregulation, and dynamic changes in competition.

The authors investigate the effects of technological change, deregulation, and dynamic changes in competition on the performance of U.S. banks. The authors' most striking result is that during 1991-1997, cost productivity worsened while profit productivity improved substantially, particularly for banks engaging in mergers. The data are consistent with the hypothesis that banks tried to maximize profits by raising revenues as well as reducing costs. Banks appeared to provide additional or higher quality services that raised costs but also raised revenues by more than the cost increases. The results suggest that methods that exclude revenues when assessing performance may be misleadingBanks and banking ; Bank mergers

Small business credit scoring and credit availability

U.S. commercial banks are increasingly using credit scoring models to underwrite small business credits. This paper discusses this technology, evaluates the research findings on the effects of this technology on small business credit availability, and links these findings to a number of research and public policy issues.

Global integration in the banking industry

Lowered regulatory barriers and advances in technology have reduced the cost of supplying banking services across borders. At the same time, growth in activity by multinational corporations has increased the demand for international financial services. As a result, many observers believe that global integration is under way in the banking industry, that banks are expanding their reach across borders, and that many banking markets will therefore develop large foreign components. The authors report on a study conducted by them, along with Qinglei Dai and Steven Ongena, that examined the nationality and international reach of banks that provide short-term financial services across Europe to affiliates of multinational corporations. The present article also looks at time-series data that provide a more recent look at the progress of integration in Europe. Based on a 1996 survey of more than 2,000 affiliates, the study found that an affiliate is most likely to choose a bank headquartered in the nation in which it is operating (a host-nation bank) rather than a bank headquartered in the home country of the affiliate or in a third nation. The affiliate is also more likely to select a bank limited to local or regional operations rather than one with global reach. The findings are consistent with the proposition that affiliates most value a bank that understands the culture, business practices, and regulatory conditions of the country in which the affiliate operates, and that host-nation banks possess a competitive advantage over other banks in this regard. The time-series data--on syndicated loans, foreign bank claims, and the dispersion of consumer goods prices across Europe--are also consistent with the picture drawn from the 1996 survey. The article concludes that banking markets evidently need not become more integrated even as economic activity otherwise becomes increasingly global.Banks and banking ; International finance

Risk-based capital and deposit insurance reform

Risk-based capital (RBC) is an important component of deposit insurance reform. This paper provides an empirical analysis of the new 1992 RBC bank standards, applying them to data on virtually all U.S. banks from 1982 to 1989. The data reveal strong associations between several measures of future bank performance (including bankruptcy) and the RBC relative risk weights. These associations suggest that the weights constitute a significant improvement over the old capital standards, although there are several instances in which the weights for specific categories appear to be out of line with the performance results. Tests of the informational value of passing or failing the new and old capital standards show that both have independent information, but that the new RBC standards better predict future bank performance problems. The data also indicate that, in contrast to the old standards, the RBC capital burden falls much more heavily on large banks. As a result, banks representing more than one-fourth of all bank assets would have failed the new RBC standards as of 1989. The new standards are also more stringent overall. More banks would have failed the new standards than the old ones, with larger average capital deficiencies.Deposit insurance ; Bank supervision ; Bank capital

"Lines of Credit and Relationship Lending in Small Firm Finance"

This paper examines the role of_.relationship..lending.using a data set on small firm finance. We specifically examine price and nonprice terms of commercial bank lines of credit (L/C) extended to small firms. Our focus on bank L/Cs allows us to examine a type of loan contract where the bank-borrower relationship is likely to be an important mechanism for solving asymmetric information problems associated with financing small enterprises. We find that borrowers with longer banking relationships tend to pay lower interest rates and are less likely to pledge collateral. These results are consistent with theoretical arguments that relationship lending generates valuable information about borrower quality.

What explains the dramatic changes in cost and profit performance of the U.S. banking industry?

The authors investigate the sources of recent changes in the performance of U.S. banks using concepts and techniques borrowed from the cross-section efficiency literature. Their most striking result is that during 1991-1997, cost productivity worsened while profit productivity improved substantially, particularly for banks engaging in mergers. The data are consistent with the hypothesis that banks tried to maximize profits by raising revenues as well as reducing costs, and that banks provided additional services or higher service quality that raised costs but also raised revenues by more than the cost increases. The results suggest that methods that exclude revenues may be misleading.Banks and banking - Costs ; Banks and banking

Efficiency and productivity change in the U.S. commercial banking industry: a comparison of the 1980s and 1990s

The authors investigate efficiency and productivity growth of the U.S. banking industry over the latter part of the 1980s and first part of the 1990s using comprehensive data on U.S. commercial banks. Cost efficiency decreased slightly between the 1980s and 1990s, and large banks showed a sizable decline in profit efficiency. Total predicted production costs increased over both the 1980s and 1990s, reflecting cost productivity declines. Changes in business conditions led to cost declines over both periods. Total predicted profits increased in the 1980s and 1990s, with the entire change reflecting increased profit productivity. Changing business conditions led to small declines in profits.Banks and banking ; Productivity

Loan commitments and bank risk exposure

Loan commitments increase a bank's risk by obligating it to issue future loans under terms that it might otherwise refuse. However, moral hazard and adverse selection problems potentially may result in these contracts being rationed or sorted. Depending on the relative risks of the borrowers who do and do not receive commitments, commitment loans could be safer or riskier on average than other loans. the empirical results indicate that commitment loans tend to have slightly better than average performance, suggesting that commitments generate little risk or that this risk is offset by the selection of safer borrowers.Bank loans ; Risk
