Abstract:

We develop a general approach to exploring how regret influences strategic interaction and risky choice. Regret is captured by the payoff gap between what a player gets and what he believes he would have gotten had he chosen differently. Ex post beliefs are critical to that evaluation; the modeling therefore draws on tools from psychological game theory. Predictions depend in novel ways on the information structure across end-nodes and assumptions regarding the precise nature of chance moves. Regret can have a powerful impact in a variety of economic settings including, e.g., climate action, delegation, gambling, market entry, and information revelation.
