Abstract

A simple model is developed to analyze the effects of social media use by a bank’s uninsured depositors. While social media increases the likelihood of bank runs, it can be ex-ante beneficial to a bank by raising its shareholders’ equity. Social media enhances monitoring of a bank’s financial condition, thereby giving uninsured depositors a valuable option to withdraw early and avoid potential losses in states when a bank is likely to be insolvent. Recognizing this option, uninsured depositors require a lower promised interest rate that reduces the bank’s cost of funding at the expense of a greater liability for the bank’s deposit insurer.

银行储户使用社交媒体的影响
本文建立了一个简单的模型来分析银行未投保储户使用社交媒体的影响。虽然社交媒体会增加银行挤兑的可能性,但它可以通过提高股东权益而事先给银行带来好处。社交媒体加强了对银行财务状况的监控,从而为未投保储户提供了一个宝贵的选择,即在银行可能破产的情况下提前取款,避免潜在损失。由于认识到这一选择,未投保的储户需要较低的承诺利率,以降低银行的融资成本,但银行的存款保险公司则需要承担更大的责任。
