Big Bad Banks? The Winners and Losers from Bank Deregulation in the United States
研究了美国1970-1990年代各州取消银行分支机构限制对收入分配的影响，发现放松管制通过提高低技能工人的工资和工作时长，缩小了收入差距。
ABSTRACT We assess the impact of bank deregulation on the distribution of income in the United States. From the 1970s through the 1990s, most states removed restrictions on intrastate branching, which intensified bank competition and improved bank performance. Exploiting the cross‐state, cross‐time variation in the timing of branch deregulation, we find that deregulation materially tightened the distribution of income by boosting incomes in the lower part of the income distribution while having little impact on incomes above the median. Bank deregulation tightened the distribution of income by increasing the relative wage rates and working hours of unskilled workers.
