| Outline of Final Research Achievements |
This study tests the theory of investors' heterogeneous beliefs and short-sale constraints as a potential explanation for the long-run underperformance of initial public offerings (IPOs); the theory states that the first-day price is overvalued because it only reflects optimistic investors' opinions and the resale option value brought on by short-sale constraints. This theory is difficult to test directly because investor opinion distribution is unobservable. This study focuses on Japanese auction method IPOs and estimates the investor belief distribution. As predicted by the theory, IPOs with higher proportions of optimistic investors are indeed associated with lower long-run returns.
