The main purpose of this paper is to estimate the size and the growth of Quebec's underground economy, and the corresponding loss of taxes for the government. Our approach is based on a method developed by Pissarides and Weber (1989) and extended by Lyssiotou et al. (2004). The basic hypothesis...

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...

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...

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...

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...

We investigate whether peer effects at work differ by gender and whether the gender difference in peer effects – if any – depends on work organization, precisely the structure of social networks. We develop a social network model with gender heterogeneity that we test by means of a...
