“Social Dilemmas, Inequality and Compliance: Evidence from Experiments” 

by Lata Gangadharan 

 Abstract: Tensions between private and social interests give rise to social dilemmas. We first examine situations where some individuals enjoy greater benefits from the environmental public good than others. We show that normative conflict induced by inequality can be difficult to overcome, imposing limits on the ability of heterogeneous populations to reach efficient outcomes through self-governance. An environmental tax and redistribution mechanism can help resolve the trade-off between efficiency and inequality and also eliminate the observed perverse effect of social information and observability on cooperation. Next, we turn towards regulatory compliance and examine the role of different schemes, notably those based on competition, principle-agent contracts, or peer networks, in improving compliance.
