The Incidence of Income Taxation on Household Labour Supply: A Collective Approach


Research objectives and content

In a (so-called) collective model, each household member is characterised by his (her) own utility function and decisions result in Pareto-efficient outcome. This framework is generally sufficient to generate testable restrictions and recover the outcome of the decision process (the sharing rule).

Our project is to:
(i) investigate from a theoretical point of view the consequences of introducing income taxation in this framework (i.e. to extend the initial results on integrability and testability) and
(ii) estimate some collective models incorporating income taxation with French data.

Precisely, we refer to the issue of measuring the tax incidence on household behaviour. Remark also that the collective approach raises an interesting question which is usually disregarded by traditional models, i.e. the effect of taxation on the intrahousehold allocation of welfare.

Training content (objective, benefit and expected impact)

Based on a theoretically more pertinent model of the household, in our opinion, the main results of our research should be compared with the existing literature on tax incidence and make its contributions to an always open debate. Not surprisingly, simulations of fiscal reforms are expected to give quite different results from those previously published and for the first time indications on the consequences for each member's welfare will be provided.
