The contribution of on-site examination ratings to an emprircal model of bank failures
This paper investigates how well regulator examinations predict bank failures, and how best to incorporate examination information into an econometric model of time-to-failure. We estimate proportional hazard models with time-varying covariates and find that examiner ratings help explain the failure hazard. Both the overall rating of a bank's condition and management, i.e., the composite CAMELS rating, and ratings of specific components contain information. In addition, we find that the marginal "effect" of ratings is non-linear, in that the impact of a rating downgrade on the probability ...

Trends in the efficiency of Federal Reserve check processing operations
The Monetary Control Act of 1980 requires the Federal Reserve to charge customers for financial services, with the intent of improving the efficiency with which Fed offices deliver those services. Prior studies found little improvement in the efficiency of Fed check processing operations after pricing was implemented in 1982. This article examines the efficiency of Fed check operations using a longer sample period (1980:Q1?2003:Q3) than previous studies and new methods for estimating efficiency. The authors find that the median office became somewhat less efficient when pricing was ...

Robust, dynamic nonparametric benchmarking: the evolution of cost-productivity and efficiency among U.S. credit unions
This paper develops a new methodology for estimating cost-productivity and efficiency change that benchmarks the performance of individual firms against an estimated a-quantile. We adapt the estimators of Daouia and Simar (2007) and Wheelock and Wilson (2008a) to the estimation of cost efficiency where input prices and some outputs are fixed. Theoretical results demonstrate that our new estimator retains the root-n convergence, asymptotic normality, and other desirable properties of the original estimators. We show how the estimator can be used to construct a cost analog of the widely-used ...

Are U.S. banks too large?
The number of commercial banks in the United States has fallen by more than 50 percent since 1984. This consolidation of the U.S. banking industry and the accompanying large increase in average (and median) bank size have prompted concerns about the effects of consolidation and increasing bank size on market competition and on the number of banks that regulators deem ?too big to fail.? Agency problems and perverse incentives created by government policies are often cited as reasons why many banks of pursued acquisitions and growth, though bankers often point to economies of scale. This paper ...

New evidence on the Fed's productivity in providing payments services
As the dominant provider of payments services, the efficiency with which the Federal Reserve provides such services in an important public policy issue. This paper examines the productivity of Federal Reserve check-processing offices during 1980-1999 using non-parametric estimation methods and newly developed methods for non-parametric inference and hypothesis testing. The results support prior studies that found little initial improvement in the Fed's efficiency with the imposition of pricing for Federal Reserve services in 1982. However, we find that median productivity improved ...

Are credit unions too small?
Since 1985, the share of U.S. depository institution assets held by credit unions has nearly doubled, and the average (inflation-adjusted) size of credit unions has increased over 600 percent. We use a non-parametric local-linear estimator to estimate a cost relationship for credit unions and derive estimates of ray-scale and expansion-path scale economies. We employ a dimension-reduction technique to reduce estimation error, and bootstrap methods for inference. We find substantial evidence of increasing returns to scale across the range of sizes observed among credit unions, suggesting that ...

Why do banks disappear? The determinants of U.S. bank failures and acquisitions
This paper examines the determinants of individual bank failures and acquisitions in the United States during 1984-1993. We use bank-specific information suggested by examiner CAMEL-rating categories to estimate competing-risks hazard models with time-varying covariates. We focus especially on the role of management quality, as reflected in alternative measures of x-efficiency and find the inefficiency increases the risk of failure, while reducing the probability of a bank's being acquired. Finally, we show that the closer to insolvency a bank is, as reflected by a low equity-to-assets ratio, ...

The Evolution of Scale Economies in U.S. Banking
Continued consolidation of the U.S. banking industry and a general increase in the size of banks has prompted some policymakers to consider policies that discourage banks from getting larger, including explicit caps on bank size. However, limits on the size of banks could entail economic costs if they prevent banks from achieving economies of scale. This paper presents new estimates of returns to scale for U.S. banks based on nonparametric, local-linear estimation of bank cost, revenue and profit functions. We report estimates for both 2006 and 2015 to compare returns to scale some seven ...

Non-parametric, unconditional quantile estimation for efficiency analysis with an application to Federal Reserve check processing operations
This paper examines the technical efficiency of U.S. Federal Reserve check processing offices over 1980?2003. We extend results from Park et al. (2000) and Daouia and Simar (2007) to develop an unconditional, hyperbolic, a-quantile estimator of efficiency. Our new estimator is fully non-parametric and robust with respect to outliers; when used to estimate distance to quantiles lying close to the full frontier, it is strongly consistent and converges at rate root-n, thus avoiding the curse of dimensionality that plagues data envelopment analysis (DEA) estimators. Our methods could be used by ...

Consolidation in US banking: which banks engage in mergers?
The number of U.S. commercial banks has declined by some 40 percent since 1984, primarily through mergers of solvent institutions. The relaxation of legal impediments to branching has enabled this consolidation, but specific characteristics of banks that engage in mergers reflect the regulatory process and market structure, as well as the bank's own condition. This paper seeks to quantify the regulatory, market, and financial characteristics that affect the probability of a bank engaging in mergers and the volume of banks it absorbs over time. We examine separately consolidation within ...
