More on the Price-Responsiveness of Food Consumption

Cornelsen et al. (2014) and Green et al. (2013) provide a comprehensive review/summary of a large number of recent estimates of the price responsiveness of food consumption using a meta-regression approach. For seven food items, they present uncompensated elasticities that include both the income and substitution effects of price changes. As for some policy purposes, the substitution effects need to be isolated, in this note we introduce a way of recovering these in the form of the compensated elasticities from their uncompensated counterparts.
