While the theoretical literature on contracts has been enormous since the seventies, empirical tests of the theory have long remained scarce. However, new empirical work has been developed in the last ten years that sheds light on the empirical validation of the theory. This paper aims at...

Is general equilibrium theory empirically testable? Our perspective on this question differs from the standard, Sonnenschein-Debreu-Mantel (SDM) viewpoint. While SDM tradition considers aggregate (excess) demand as a function of prices, we assume that what is observable is the equilibrium price...

We extend the collective model of household behavior to allow for the existence of public consumption. Under a separability assumption, we show that the observation of the labor supplies and the household demand for the public good allow to identify preferences and the decision process up to...

This paper empirically analyzes moral hazard in car insurance using a dynamic theory of an insuree's dynamic risk (ex ante moral hazard) and claim (ex post moral hazard) choices and Dutch longitudinal micro data. We use the theory to characterize the heterogeneous dynamic changes in incentives...

We present identification and estimation results for the collective model of labour supply in which there are discrete choices, censoring of hours and nonparticipation in employment. We derive the collective restrictions on labour supply functions and contrast them with restrictions implied by...

Stable matchings may fail to exist in the roommate matching problem, both when utility is transferable and when it is not. We show that when utility is transferable, the existence of a stable matching is restored when there is an even number of individuals of indistinguishable characteristics...

We consider a matching model in which individuals belonging to two populations (\textquotedblleft males\textquotedblright\ and \textquotedblleft females\textquotedblright ) can match to share their exogenous income risk. Within each population, individuals can be ranked by risk aversion in the...

In this note, we address nonparametric identification of a collective model of household behavior in the presence of additive unobserved heterogeneity in the sharing rule. We show that the (nonstochastic part of the) sharing rule is nonparametrically identified. Moreover, under independence...

This paper adopts an intertemporal labor supply perspective to propose a test that allows us to distinguish between intra-household non-commitment, limited commitment, and full commitment. It investigates whether, after controling for current and future (expected) wages, past wage shocks have a...
