Time allocation within the family: Welfare implications of life in a couple

A collective model of leisure demand, generalised to the production of a household public good, is estimated on the British Household Panel Survey. The sharing rule is identified by using an original parametric framework based on the change of family status: from single-living to couple or from couple to single-living. Womens' ratios of private household expenditures are 40% on average. The level of intra-household inequality appears highly dependent on the intra-household wage gap. Omitting household production in the model would overestimate the ratio by 7 percentage points on average.
