The Effect of the Japan 2011 Disaster on Nuclear and Alternative Energy Stocks Worldwide: An Event Study

This event study investigates the impact of the Japanese nuclear disaster in Fukushima-Daiichi on the daily stock prices of French, German, Japanese, and U.S. nuclear utility and alternative energy firms. Hypotheses regarding the (cumulative) abnormal returns based on a three-factor model are analyzed through joint tests by multivariate regression models and bootstrapping. Our results show significant abnormal returns for Japanese nuclear utility firms during the one-week event window and the subsequent four-week post-event window. Furthermore, while French and German nuclear utility and alternative energy stocks exhibit significant abnormal returns during the event window, we cannot confirm abnormal returns for U.S. stocks.

Board Overlap, Seat Accumulation and Share Prices

We examine the board overlap among firms listed in Switzerland. Collusion, managerial entrenchment, and financial participation cannot explain it. The overlap appears to be induced by banks and by the accumulation of seats by the most popular directors. We also document that seat accumulation is negatively related to firm value, possibly because of the conflicts of interest that multiple directorships induce and the time constraints directors face. Contrary to popular beliefs, however, the directors of traded firms do not generally hold more than one mandate in other traded firms. They do hold multiple seats in non-traded firms.
