We compare the experimental results of three stag-hunt games. In contrast to Battalio et al. (2001), our design keeps the riskiness ratio of the payoff-dominant and the risk-dominant strategies at a constant level as the optimisation premium is increased. We define the riskiness ratio as the...

The ambient tax is often considered as an efficient instrument to achieve a first best outcome of ambient pollution when the regulator cannot observe individual emissions, or when monitoring costs are prohibitive. While this view is supported to a large extent by experimental findings, there...
