| Abstract: | The 1994 Riegle‐Neal Act (RN) removed restrictions on branch‐network expansion for banks in the United States. An important motivation was to facilitate geographic risk diversification (GRD). Using a factor model to measure banks' geographic risk, we show that RN expanded GRD possibilities in small states, but only some large banks took advantage. Using our measure of geographic risk and an empirical model of branch‐network choice, we identify preferences toward GRD separately from other factors possibly limiting network expansion. Counterfactuals show that risk negatively affected bank value but was counterbalanced by economies of density/scale, reallocation/merging costs, and local market power concerns. |
