The Inconsistency between Asymmetric Information Theory and Empirical Evidence in Insurance Markets

                (Chu-Shiu Li)*(Chwen-Chi Liu)*(Jia-Hsing Yeh)

By reviewing recent papers on asymmetric information in the insurance field, this study analyzes the inconsistency between theory and empirical evidence. The inconsistency may exist due to inappropriate econometric methods, data limitations, the designation of contracting and underwriting, the nonexistence of assumptions, and the need for new developments in theory.
Keywords: asymmetric information, adverse selection, moral hazard
