Do earthquakes make men more risk tolerant?

We investigate whether individuals’ risk preferences change after experiencing a natural disaster, specifically, the 2011 Great East Japan Earthquake. Exploiting the panels of nationally representative surveys on risk preferences, we find that men who experienced greater intensity of the earthquake became more risk tolerant a year after the Earthquake. Interestingly, the effects on men’s risk preferences are persistent even five years after the Earthquake at almost the same magnitude as those shortly after the Earthquake. Furthermore, these men gamble more, which is consistent with the direction of changes in risk preferences. We find no such pattern for women.

That is from a newly published paper by Chie Hanaoka, Hitoshi Shigeoka, and Yasutora Watanabe.  What else will have this effect?
