Abstract
A disaster, like a big earthquake, can be regarded as a kind of “Catastrophe”. In this study, we concentrated on the catastrophe, which is predicted, but not known when to happen. The aim of this study is to find the cooperative behavior when the catastrophe occurs using the “Catastrophe Game” modified from Public Goods Game. As a result, we could not observe (a) the effect of advance notice of a catastrophe. On the other hand, we found (b) victims’ cooperative behavior after catastrophe in Total Catastrophe Game in which occurred to all players. Similarly, we did (c) victims’ cooperative behavior and (d) non-victims’ cooperative behavior after catastrophe in Partial Catastrophe Game in which to a part of the players.
