道德风险/moral hazard & 逆向选择/adverse selection 的主要区别

Distinguishing Moral Hazard from Adverse Selection

In both moral hazard and adverse selection, there is information asymmetry between the two parties. The main difference is when it occurs.

In a moral hazard situation, the change in the behavior of one party occurs after the agreement has been made. However,

in adverse selection, there is a lack of symmetric information prior to when the contract or deal is agreed upon.
