The Effect of Inequality Aversion on a Climate Coalition Formation: Theory and Experimental Evidence

This chapter examines the impact of inequality-averse attitudes on the individual incentives of participating in international environmental agreements by a laboratory experiment. The experimental result shows that the inequality-averse attitudes have significantly positive impact on the incentives of participation. Particularly, when they are non-critical players, egalitarians are likely to give up the free riding benefit by joining a coalition. It helps us to understand the coalition formation in the international conventions.
