Abstract
This paper adopts a "piece-meal" approach to empirically identify, on a sample of Italian households, a collective model where both nonparticipation and non-convex budget sets are allowed for. Two tax reforms, i.e. the 2002 tax changes recently introduced in Italy and a revenue neutral linear income tax are evaluated by the collective framework derived. The predictions obtained for individual labour supplies, income and welfare distribution are then compared with those of a traditional unitary model. The exercise provide an assessment of the distortion introduced in positive and normative analyses when individuals are assumed to behave as if in a unitary, rather than in a collective world. The results suggest that further efforts should be devoted to the analysis of intra-household decision models.collective models; intra household allocation; tax reform
