Abstract

This paper examines the effects on social welfare of changes in coverage levels within deposit insurance schemes. It utilizes a solid theoretical framework and takes advantage of a quasi-natural experiment and bank-level data to measure the impact of an increase in Colombia’s deposit insurance coverage level. For the case studied, the benefits outweigh the costs, resulting in a positive net impact on welfare. However, some banks concentrate most of the gains. The size of a bank, its probability of default, and the change in the percentage of insured deposits that occurred due to the increase in the coverage level are critical. Two extensions of the main model are also analyzed. The first allows banks to be bailed out because of “too-big-to-fail” considerations, and the second incorporates banks’ reaction to the increase in the coverage level. The benefits of increasing the coverage level remain positive in both cases but are lower than using the main model.

衡量存款保险覆盖水平变化的影响：来自哥伦比亚的调查结果

本文考察了存款保险制度覆盖水平变化对社会福利的影响。它利用坚实的理论框架，利用准自然实验和银行层面的数据来衡量哥伦比亚存款保险覆盖水平提高的影响。对于所研究的案例，收益大于成本，对福利产生了积极的净影响。然而，一些银行集中了大部分收益。银行的规模、违约的可能性，以及由于覆盖水平的提高而发生的受保存款百分比的变化都是至关重要的。对主要模型的两种扩展进行了分析。前者允许银行出于“太大而不能倒”的考虑而接受纾困，后者则包含了银行对覆盖率提高的反应。在这两种情况下，增加覆盖水平的好处仍然是积极的，但比使用主要模型的好处要低。
