Les échelles d'équivalence complètes : une estimation intégrant les dimensions monétaire et temporelle des dépenses des ménages

The statistical match of a Family Budgets survey and Time Use survey (INSEE 2000) makes possible, once evaluated the cost of the time, the estimation of the full expenditure of household integrating the value of the domestic production and the monetary expenditure. The full cost of the child computed using the classic methods of demand systems estimation is higher than the child cost obtained by the monetary approach. To a lesser extent the same result is obtained for the cost of a second adult. The economies of scale seem to be stronger in the time use dimension than for monetary expenditure. Also, the inequality of the full incomes obtained by the matching is lower than those computed on monetary incomes only.
