The Causal Impact of Distance on Bank Lending
利用基础设施改善作为旅行时间的外生冲击，研究发现距离缩短增加了新银行关系的建立，银行通过提高利率获取部分经济剩余，而竞争银行的距离缩短则产生相反效果。
We investigate the role of physical distance in corporate lending by exploiting infrastructure improvements as shocks to travel time. Lower travel time increases the likelihood of initiating a new banking relationship, consistent with an economic surplus from lower transaction costs. In existing lending relationships, banks capture part of this surplus by increasing interest rates, in particular, if banks have higher bargaining power. Reductions in travel time to competing banks have the opposite effects. Banks benefit from improved infrastructure through an increase in clients, and lenders that rely more on technology do not exhibit sensitivity to changes in distance.
