A complete system of Engel curves in the Spanish economy
The main goal of this article is the estimation of the consumption-income relationship along with socio-economic factors using cross section data from the Spanish Household Expenditure Survey 1991. The data has been grouped according to exogenous criteria to avoid the problem of null expenditure. First, a non-linear system of equation is estimated, from which the linear form that best fits the used data is tested. Finally, income elasticities are calculated considering three alternative formulations depending on how an initial income increment is distributed among consumers. Income elasticities are shown for the whole income distribution
