This paper uses micro data from a random survey carried out in the region of Quebec City, Canada, to estimate a model of labor supply in the underground economy. The model assumes that the individual's gross wage rate in the regular sector is parametric while his gross labor earnings in the...

This paper uses micro data from a randomized survey carried out in the metropolitan area of Quebec City, Canada, to analyze the decision to evade taxes and work in the 'underground' economy. The results indicate that taxes distort labor-market activities away from the regular sector to the...

Qui a les moyens d'engager un travailleur de la construction pour faire rénover sa cuisine ou réparer son toit, de le payer au taux officiel et d'ajouter TPS et TVQ ?Qui a déjà résisté à l'offre de rémunérer à un prix raisonnable un service en payant « sous la table » ? Qui n'a...

In this paper we model female labor supply within a discrete choice framework. Two different rationing mechanisms are incorporated into the model: involuntary unemployment and underemployment. The model is set-up as a generalization of the Double-Hurdle model of Cragg [1971]. Our estimation...

We provide an analysis of the effect of physician payment methods on their hospital patients' length of stay and risk of readmission. To do so, we exploit a major reform implemented in Quebec (Canada) in 1999. The Quebec Government introduced an optional mixed compensation (MC) scheme for...

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...

Collective rationality is seldom if ever rejected in the literature, raising doubt about its falsifiability. We show that the standard approach to test the collective model with distribution factors may yield misleading inference. We generalize the model and provide an appropriate test procedure...

This paper aims at opening the black box of peer effects in adolescent weight gain. Using Add Health data on secondary schools in the U.S., we investigate whether these effects partly flow through the eating habits channel. Adolescents are assumed to interact through a friendship social network....

We provide new results regarding the identification of peer effects. We consider an extended version of the linear-in-means model where each individual has his own specific reference group. Interactions are thus structured through a social network. We assume that correlated unobservables are...
