註釋The paper uses the matching probabilities method to elicit ambiguity perceptions and attitudes to ambiguity in three strategic interactions, a contest, a coordination game, and a Rock-Paper-Scissors game, and a standard Ellsberg setup. We find remarkable stability of attitudes to ambiguity across all four environments. In contrast, subjects perceived a significantly greater amount of ambiguity in the minimum-effort coordination game, which has multiple equilibria and entails considerably more strategic uncertainty than the other games. Our findings suggest that ambiguity is ubiquitous in strategic interactions and its role is closely tied to the amount of strategic uncertainty.
