Outline of Final Research Achievements

Focusing on seasoned equity offering and share repurchases in Japan, the divergence of opinion hypothesis has been examined as a possible explanation to the puzzling stock price behavior during the issuance (or repurchase) period (Kato, Singh and Suzuki (2015), Bremer, Kato, Singh and Suzuki (2015)). Okada et al. (2015) shows the neglected stocks tend to react slowly to the new information to the market and as a result, the market underreacts to the news. Inoue et al.(2015) explore the impact of corporate cultures on cross-border acquisitions. Inoue et al. find that acquirers from countries with a high uncertainty aversion conduct less cross-border M&As. Muramiya, Yamamoto and Yamasaki (2015) show that become synchronous with the market due to investors’ limited attention after a catastrophic event, stock prices. Further, crush risk is higher for more opaque firms.
