The Effects of Interstate Banking on Commercial Banks' Risk and Profitability
利用资本市场数据和事件研究方法，检验跨州银行对商业银行风险与盈利能力的影响，发现跨州银行能提高银行盈利能力，但同时也显著增加了市场风险暴露。
Historically, the effect of interstate banking on the risk and profitability of commercial banks has been a controversial issue. Using capital market data and an event study methodology, the author tests the effects of interstate banking. The findings of this paper reject the hypothesis that interstate banking has no effect on banks' risk and profitability. The evidence supports the argument that interstate banking benefits commercial banks in terms of increased profitability, but the increase in profitability is also associated with significant increases in the banks' exposure to market risk.
