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, ...

New Estimates of the Lerner Index of Market Power for U.S. Banks
The Lerner index is widely used to assess firms' market power. However, estimation and interpretation present several challenges, especially for banks, which tend to produce multiple outputs and operate with considerable inefficiency. We estimate Lerner indices for U.S. banks for 2001-18 using nonparametric estimators of the underlying cost and profit functions, controlling for inefficiency, and incorporating banks' off-balance-sheet activities. We find that mis-specification of cost or profit functional forms can seriously bias Lerner index estimates, as can failure to account for ...

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 ...

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 ...

Nonparametric Estimation of Lerner Indices for U.S. Banks Allowing for Inefficiency and Off-Balance Sheet Activities
The Lerner index is widely used to assess firms' market power. However, estimation and interpretation present several challenges, especially for banks, which tend to produce multiple outputs and operate with considerable inefficiency. We estimate Lerner indices for U.S. banks for 2001-18 using nonparametric estimators of the underlying cost and profit functions, controlling for inefficiency, and incorporating banks' off-balance-sheet activities. We find that mis-specification of cost or profit functional forms can seriously bias Lerner index estimates, as can failure to account for ...

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 ...

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 ...

Turbulent Years for U.S. Banks: 2000-20
The first 20 years of the twenty-first century have presented U.S. banks with three recessions, long periods of very low interest rates, and increased regulation. The number of commercial banks operating in the United States declined by 51 percent during this period. This article examines the performance of U.S. commercial banks from 2000 through 2020. An overall picture is provided by examining the evolution of assets, deposits, loans, and other financial characteristics over the period. In addition, new estimates of technical inefficiency are provided, offering additional insight into ...

Robust non-parametric quantile estimation of efficiency and productivity change in U.S. commercial banking, 1985-2004
This paper describes a non-parametric, unconditional, hyperbolic quantile estimator that unlike traditional non-parametric frontier estimators is both robust to data outliers and has a root-n convergence rate. We use this estimator to examine changes in the efficiency and productivity of U.S. banks between 1985 and 2004. We find that larger banks experienced larger efficiency and productivity gains than small banks, consistent with the presumption that recent changes in regulation and information technology have favored larger banks.
