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 presents new estimates of ray-scale and expansion-path scale economies for U.S. banks based on nonparametric local-linear estimation of a model of bank costs. Unlike prior studies that use models with restrictive parametric assumptions or limited samples, our methodology is fully nonparametric and we estimate returns to scale for all U.S. banks over the period 1984-2006. Our estimates indicate that as recently as 2006, most U.S. banks faced increasing returns to scale, suggesting that scale economies are a plausible (but not necessarily only) reason for the growth in average bank size and that the tendency toward increasing scale is likely to continue unless checked by government intervention.
