This paper presents the first evidence linking directly household consumption profiles to the widely studied institution of sharecropping in developing countries. On the one hand, the theoretical rationale for sharecropping often calls for its risk sharing properties. On the other hand empirical...

This paper analyzes the demand and cost structure of the french market of academic journals, taking into account its intermediary role between researchers, who are both producers and consumers of knowledge. This two sidedness feature will echoes similar problems already observed in electronic...

We propose a structural empirical approach à la Levinsohn and Petrin (2003) to disentangle the effect of experts' grades from the effect of unobserved quality on the pricing of experience goods. Using a panel data set of 108 châteaux selling wine on the Bordeaux "en primeur" market, we provide...

Sharecropping theory generally does not take into account land fertility. We develop a repeated Principal-Agent model under moral hazard where the Principal delegates the use and maintenance of a productive asset. In a multitask framework, we characterize the optimal spot contract focusing on...

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

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

In this paper, we study the determinants of the value of informal risk sharing groups. In particular, we look at the effects of heterogeneity of preferences and of limited commitment constraints that restrict feasible allocations differently if individuals can deviate form risk sharing...

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...

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...
