摘要：We show that endogenous firm selection provides a new welfare margin for heterogeneous firm models of trade (relative to homogeneous firm models). Under some parameter restrictions, the trade elasticity is constant and is a sufficient statistic for welfare, along with the domestic trade share. However, even small deviations from these restrictions imply that trade elasticities are variable and differ across markets and levels of trade costs. In this more general setting, the domestic trade sha...

摘要：The conventional wisdom since Yaari (1965) is that households without a bequest motive should fully annuitize their investments. Numerous frictions do not break this sharp result. We modify the Yaari framework by allowing a household's mortality risk itself to be stochastic due to health shocks. A lifetime annuity still helps to hedge longevity risk. But the annuity's remaining present value is correlated with medical costs, such as those for nursing home care, thereby reducing annuity demand,...

摘要：We consider vertical contracting arrangements between a manufacturer and a retailing network when retailers have private information and the organization is run through bilateral contracts. We highlight a new form of informational opportunism arising when the manufacturer manipulates information learned separately in each relationship. We characterize the set of allocations robust to such opportunism by means of simple ex post incentive compatibility constraints. Those constraints limit the ma...

摘要：Many lament that weak accountability and poor governance impede economic development in Africa. Politicians rely on ethnic allegiances that deliver the vote irrespective of performance, dampening electoral incentives. Giving voters information about candidate competence counters ethnic loyalty and strengthens accountability. I extend a canonical electoral model to show how information provision flows through voter behavior and ultimately impacts the distribution of political spending. I test t...

摘要：Drug trade-related violence has escalated dramatically in Mexico since 2007, and recent years have also witnessed large-scale efforts to combat trafficking, spearheaded by Mexico's conservative PAN party. This study examines the direct and spillover effects of Mexican policy toward the drug trade. Regression discontinuity estimates show that drug-related violence increases substantially after close elections of PAN mayors. Empirical evidence suggests that the violence reflects rival trafficker...
