PIERI-12916 “The Unitary versus the Collective model, an experimental approach in rural areasâ€


Evaluations of social programs on welfare and poverty are usually cast in the unitary framework, which assumes that households, even if they consist of several individuals, behave as if they were single decision-making units. One important deficiency of the unitary approach, from a welfare economic point of view, is that it is not able to say anything about the intra-household allocation of welfare. It has been recently recognized the fact that impact evaluation should not ignore intra-household distributional issues. Moreover, the theoretical implications of the collective model have been repeatedly tested and rejected. Fortin and Lacroix (1997) soundly reject the collective model when confronted with observational data in the context of household labour supply.
