An Empirical Examination of Information Barriers to Trade in Insurance
利用直接证据检验信息不对称是否阻碍了全球最大私人保险市场（人寿保险）的交易，发现传统理论难以解释的现象，并提出卖方可能比买方更了解生产成本。
This paper uses direct evidence to evaluate whether asymmetric information is a barrier to trade in the largest market for private insurance in the world: life insurance. We report several findings that seem difficult to reconcile with the conventional theory of insurance under asymmetric information. We conjecture that sellers may know their costs of production better than consumers in this market, as in those for most other products.
