A fundamental question in monopolistic competition theory is whether the market allocates resources efficiently. This paper generalizes the Spence-Dixit-Stiglitz framework to heterogeneous firms, addressing when the market provides optimal quantities, variety and productivity. Under constant...

Legal institutions affect economic outcomes, but how much? This paper documents how costly supplier contract enforcement shapes firm boundaries, and quantifies the impact of this transaction cost on aggregate productivity and welfare. I embed a contracting game between a buyer and a supplier in...

Although firms may face radically different production conditions, this dimension of firm heterogeneity is often overlooked. We model input demand across local factor markets, explicitly considering search costs which explain why firms care about both the price and availability of inputs. The...

The political left turn in Latin America, which lagged its transition to liberalized market economies by a decade or more, challenges conventional economic explanations of voting behavior. This paper generalizes the forward-looking voter model to a broad range of dynamic, non-concave income...

There have been few attempts to empirically explain the pursuit of short term relationships and sex in a formal context. Previous work has lamented the paucity of empirical studies which utilize incentive driven behavior to draw conclusions and recommend policy. We develop a model of social...

The political left turn in Latin America, which lagged its transition to liberalized market economies by a decade or more, challenges conventional economic explanations of voting behavior. While the implications of upward mobility for the political preferences of forward-looking voters have been...

Los autores de los artículos de este libro de homenaje a Adolfo Figueroa abordan temas de desigualdad, exclusión y políticas para el desarrollo social y de la democracia.

Optimal production decisions depend on local market characteristics. This paper develops a model to explain firm labor demand and firm density across regions. Firms vary in their technology to combine imperfectly substitutable worker types, and locate across regions with distinct distributions...

Abstract Commentators on the `East Asian Miracle' of inclusive growth have often pointed toward shared rural growth policies. But why were these policies not chosen elsewhere? This paper models voters who invest in either subsistence or a complex technology in which public goods complement...
