We use data from a Brazilian social program to investigate the existence of gender bias in intrahousehold allocations of resources. The program makes cash transfers to mothers and pregnant women in poor households. Bureaucratic mistakes, beyond the control of the applicants, have inadvertently...

The inverse relationship between land productivity and farm size is an old and puzzling empirical regularity. Most explanations for this relationship rely on market imperfections that jointly determine the farm size and the household's shadow price of some productive inputs. We use plot-level...

This paper studies recursive exchange economies with short sales. Agents maximize discounted expected utility. The asset structure is general and includes real securities, infinite-lived stocks, options, and other derivatives. The main result shows the existence of a competitive equilibrium...

This essay surveys some recent empirical works about sharecropping. The basic theoretical trade-offs are discussed in the introduction. Section 1 discusses the empirical research on resource allocation. This section is divided in two subsections: one studying the effects of tenure stability on...

This paper studies a class of general equilibrium economies in which the individuals' endowments depend on privately observed effort choices and the financial markets are endogenous. The environment is modeled as a two-stage game. Individuals first make strategic financial-innovation decisions....

We generalize the Boadway and Keen (2006) model of adverse selection in a capital market to allow for risk aversion on the part of entrepreneurs. We show that the Boadway and Keen conclusion-that adverse selection leads to excessive investment-does not necessarily hold when entrepreneurs are...

Brazilian data on auto-insurance present an intriguing fact: the coexistence of policies being sold with zero and positive brokerage fees. We extend the Bertrand model of price competition to a dynamic environment in which agents face a .xed cost to switch to a new (unmatched) broker. This...

Ever since Adam Smith, share contracts have been condemned for their lack of incentives. Sharecropping tenants face incentives to undersupply productive inputs since they receive only a fraction of the marginal revenue. The empirical literature reports that lands under sharecropping are indeed...
