摘要：This study investigates how bank expertise in identifying productive projects shapes economic structures. Utilizing the U.S. interstate banking deregulation of the 1980s as a quasi-natural experiment, we find that deregulation facilitated the convergence of economic structures across states. This effect is particularly pronounced among state pairs with significantly different pre-deregulation economic structures or when one state depends on external finance while the other is more financially developed. We then develop a general equilibrium model embedded in a Lucas-island framework featuring imperfect searching and matching between banks and firms. Calibrated to U.S. data, our model accounts for approximately half of the observed convergence of economic structures between service- and manufacturing-dominated states following deregulation. Furthermore, while deregulation enhances welfare, banks may deviate from the socially optimal level of entry, either under- or over-penetrating markets, due to pricing power and labor displacement effects. The extent of these deviations is determined by banks’ entry costs and market concentration.
