Abstract: As a new financial instrument, the risk premium of CAT bond has been much higher than that of traditional bonds with same credit rating since its issue. Although mean-variance analysis testified the existence of the CAT bond premium puzzle, the studies based on the classical theory cannot explain the cause for the high premium of CAT bond perfectly. The paper tries to resolve the puzzle essfully by using the behavioral finance theory. It discusses some psychological dynamics and behaviors of investors that play a key role in the premium puzzle of CAT bond. The result shows that risk-aversion, fixed cost of education, ambiguity aversion and herd effect cause the premium puzzle of CAT bond. This discovery not only provides a very important empirical foundation to explain the high premium of CAT bond in international CAT bond market, but also provides the clues to issuing CAT bond scientifically in China.
