Estimation of income elasticities from Lorenz concentration curves: application to Canadian micro‐data

This study uses a method of estimating income elasticities of major Canadian expenditure groups. The technique is based on the implicit Engel functions derived from the Lorenz curve of permanent income and concentration curves of group‐specific expenditures. The methodology is applied to The 1996 Canadian Family Expenditure Survey. Results indicate that income elasticities for the majority of the broad expenditure categories considered in the study are inelastic and they increase monotonically with income.
