The Effects of Regulating Hidden Add‐On Costs
研究了在厂商可能隐藏附加成本（如金融产品罚金）时，价格与信息披露监管对福利的影响，发现两者存在互补性。
We examine the welfare effects of price and disclosure regulation in a model where firms can shroud add‐on costs, such as penalty fees for consumer financial products. Such regulation can increase or decrease welfare even when there are no direct costs. There are, however, strong complementarities between price controls and disclosure mandates: conditional on disclosure being mandated, price controls always (weakly) increase welfare, and conditional on prices being sufficiently constrained, disclosure mandates always (weakly) increase welfare.
