Collective household labor supply: nonparticipation and income taxation

In this paper, we adopt the usual assumptions of the collective approach, i.e., individualism and efficiency, to study household labor supply. The theoretical innovation is 2-fold. First, we incorporate the decision to participate in the labor market in the initial setting. Second, we abandon the assumption of linearity of the budget constraint. We show that (i) structural elements such as preferences or the outcome of the decision process can be recovered, and (ii) testable restrictions are generated from the observation of the household labor supplies. We also examine, for this model, how to simulate the incidence of fiscal reforms.
