Competitive dynamics of deregulation: Evidence from US banking

This paper examines the impact of increased competition from deregulation on the dynamics of the U.S. banking industry. We find the link between a bank's relative performance and its subsequent market share growth strengthens significantly after deregulation as competitive reallocation effects transfer assets to better performers. Exit dynamics also change in way:; consistent with the disciplinary role of competition. The net effect is a substantial reallocation of market share toward better banks. We conclude that earlier regulation of U.S. banks blunted this market mechanism and seriously hindered the competitive process.
