We study capital regulation in a dynamic model for bank deposits. Capital regulation addresses banks' incentive for excessive leverage that dilutes depositors, but preserves some dilution to reduce bank defaults. We show theoretically that capital regulation is subject to a time inconsistency problem. In a model with non-maturing deposits where optimal withdrawals make deposits endogenously long-term, we find commitment to have important effects on the optimal level and cyclicality of capital adequacy. Our results call for a systematic framework that limits capital regulators' discretion.
本文在一个银行储蓄的动态模型中研究资本监管机制。资本监管旨在遏制银行过度杠杆化损害储户利益的行为,但同时需保留适度杠杆以降低银行违约风险。理论分析表明,资本监管存在时间不一致性问题。通过构建包含非到期存款的模型(最优取款行为使存款内生转化为长期负债),作者发现监管承诺对资本充足率的最优水平及周期性特征具有重要影响。研究结果主张建立系统性框架以限制资本监管机构的自由裁量权。
