We study how norms can solve distributional conflict inside a clan and the efficient coordination of collective action in a conflict with an external enemy. We characterize a fully non-cooperative equilibrium in a finite game in which a self-enforcing norm coordinates the members on efficient...

This paper demonstrates the effects of ethnic and religious diversity on the quality of public spaces. Its identification strategy relies on the exogeneity of public housing allocations in France, and thereby eliminates the bias from endogenous sorting. The paper uses micro evidence of social...

This Paper analyses an overlapping generation model of public good provision under repeated voting. The public good is financed through age-dependent taxation that distorts human capital investment. Taxes redistribute income both across different skill groups and across generations. We contrast...
