Abstract: We compare the experimental results of three stag-hunt games. In contrast to Battalio et al.(2001), our design keeps the relative riskiness of the two strategies at a constant level as the optimisation premium is increased. Furthermore, we also test the effect of a decrease of the relative riskiness of the two strategies, when the optimization premium remains constant. Our results show that in the latter case, the frequency of the risk-dominant strategy increases sharply, while in the former case the frequency of the risk-dominant strategy is unaffected. However, we confirm the earlier findings of Battalio et al. that an increase of the optimisation premium, all things equal, favours best response and sensitivity to the payoff-history.
