Children are seldom accounted for in household behavioural models. They are usually assumed to have neither the capacity nor the power to influence the household decision process. The literature on collective models has so far incorporated children through the "caring preferences" of their...

This paper investigates the effect of working in the underground sector on the level of individual underground expenditures. We show that it can be decomposed into a network effect, a non-separability effect and an income effect. Our empirical analysis uses micro data from a randomized survey...

Récemment, un nouveau cadre théorique d'analyse s'est développé dans le but d'analyser les comportements des ménages avec deux conjoints. Cette approche, qualifiée de modèle collectif, suppose que chaque conjoint a des préférences individuelles et que les choix du ménage sont...

The paper extends the standard tax evasion model by allowing for social interactions. In Manski's (1993) nomenclature, our model takes into account social conformity effects (i.e., endogenous interactions), fairness effects (i.e., exogenous interactions) and sorting effects (i.e., correlated...

In this paper we estimate a model of household labor supply based on the collective approach developed by Chiappori (JPE, 1992). This approach assumes that the intra-household decision process leads to Pareto efficient outcomes. Our model extends this theory by allowing the marriage market, and...

Few studies have examined the dynamics of participation in welfare in Québec and elsewhere in Canada. This paper sheds some light on that important topic, which is crucial for the understanding of the features and of the effects of welfare programmes, and for the analysis of possible reforms....

This paper provides a theoretical framework for analyzing the impact of the marriage market and divorce legislation on household labor supply. In our approach, the sex ratio on the marriage market and the rules governing divorce are examples of "distribution factors". The latter are defined as...

In this paper we analyze the impact of benefits on the length of welfare spells. It introduces a ``natural experiment'' approach of comparing the length of welfare spells before and after a major reform of the welfare program that took place in the Province of Québec in August 1989. An...

This paper extends the standard work effort model by allowing workers to interact through networks. We investigate experimentally whether peer performances and peer contextual effects influence individual performances. Two types of network are considered. Participants in Recursive networks are...

In 2002 the Quebec government implemented the "Action Emploi" (AE) program aimed at making work pay for long-term social assistance recipients (SA). AE offered a generous wage subsidy that could last up to three years to recipients who found a full-time job within twelve months. The program was...
