Abstract:Th e study proposes a novel approach to estimate price demand elasticities at the various levels of expenditures. Th rough the expectile estimator, the demand system can be estimated not only at the mean, as is generally done when implementing the OLS, but also at the lower and higher levels of expenditure. A simple demand system of equations focusing on fi ve basic goods: Food, Recreation, Clothing, Transport, Rent, using the Canadian Family Expenditure Survey data was estimated. Th e comparison of the estima… Show more
