Abstract: We conducted a set of experiments to compare the effect of ambiguity in single person decisions and games. Our results suggest that ambiguity has a bigger impact in games than in ball and urn problems. We ?nd that ambiguity has the opposite effect in games of strategic substitutes and complements. This con?rms a theoretical prediction made by Eichberger and Kelsey (2002). The experiments also test whether subjects' ?perception of ambiguity differs when faced by a local opponent as opposed to a foreign one. Our results show that there is little evidence of more in?uence of ambiguity on behaviour when faced by foreign subjects.
