Asymmetric information in insurance: general testable implications
证明，在竞争性保险市场和风险厌恶公开的情况下，保险覆盖与事后风险之间的正相关关系仍然成立，并在法国数据上验证了这一结论，同时发现市场势力的存在。
Several recent articles on empirical contract theory and insurance have tested for a positive correlation between coverage and ex post risk, as predicted by standard models of pure adverse selection or pure moral hazard. We show here that the positive correlationproperty can be extended to general setups: competitive insurance markets and cases where risk aversion is public. We test our results on a French dataset. Our tests confirm that the estimated correlation is positive; they also suggest the presence of market power.
