Liquidity Requirements, Bank Deposits and Financial Development
研究发现，在银行体系信任度低的环境中，流动性要求通过增强银行在坏状态下对存款人的偿付能力，刺激了银行存款和金融发展。基于埃塞俄比亚2011年一项意外政策，观察到富裕个人存款增长、高收入城市新设分行存款增加以及银行资产负债表上存款、贷款和分行的扩张。
In the presence of low trust in the banking system, liquidity requirements can stimulate bank deposits and financial development by enhancing depositor repayment in bad states. We study an unannounced and unexpected policy that increased the liquid assets of Ethiopian banks by 33% in one quarter of 2011, and present three findings consistent with this hypothesis. First, a panel of depositors shows deposit growth among wealthy individuals. Second, a survey reports higher bank deposits in branches opened after the policy in high‐income cities. Third, bank balance sheets and two sources of bank exposure highlight an increase in deposits, loans and branches.
