Using data on individual consumption from farm households in the Philippines, we construct a direct test of risk-sharing within the household. We contrast the efficient outcomes predicted by the unitary household model with the outcomes we might expect if food consumption delivers not only...

We develop a model of competition between retailer chains with a structural estimation of the demand and supply in the supermarket industry in France. In the model, supermarkets compete in price and brand offer over all food products to attract consumers, in particular through the share of...

We develop and estimate a model of dynamic interactions in which commitment is limited and contracts are incomplete to explain the patterns of income and consumption growth in village economies of less developed countries. Households can insure each other through both formal contracts and...

A methodology is presented allowing manufacturers and retailers vertical contracting in their pricing strategies on a differentiated product market to be introduced. This contribution allows price-cost margins to be recovered from estimates of demand parameters both under linear pricing models...

We present a methodology allowing to introduce manufacturers and retailers vertical contracting in their pricing strategies on a differentiated product market. We consider in particular two types of non linear pricing relationships, one where resale price maintenance is used with two part...

We semiparametrically estimate the impact of the Mexican conditional cash transfer program Oportunidades on the time mothers and older sisters spend taking care of children aged under 3, using the randomization of the program placement and the methodology in Lewbel (2000). Results support the...

We study the effects of a conditional cash transfers program on school enrollment and performance in Mexico. We provide a theoretical framework for analyzing the dynamic educational process including the endogeneity and uncertainty of performance at school (passing grades) and the effect of a...

We develop and estimate a model of dynamic interactions where commitment is limited and contracts are incomplete to explain the patterns of income and consumption growth in village economies of less developed countries. Households can insure through both formal contracts and informal agreements,...

The objective of this paper is to develop an analytical framework for estimation of the parameters of a structural model of an incentive contract under moral hazard, taking into account agents heterogeneity in preferences. We show that allowing the principal to strategically distribute the...

This paper quantifies the relationship between market size and innovation in the pharmaceutical industry. We estimate the elasticity of innovation, as measured by the number of new chemical entities appearing on the market for a given disease class, to the potential market size represented by...
