Income and Price Elasticities of Food Demand and Nutrient Consumption in Malawi AgEcon
Ecker, Olivier; Qaim, Matin.
Widespread malnutrition in developing countries calls for appropriate interventions, presupposing good knowledge about the nutritional impacts of policies. Little previous work has been carried out in this direction. We present a comprehensive analytical framework, which we apply for Malawi. Using household data and a demand systems approach, we estimate income and price elasticities of food, calorie, and micronutrient consumption. These estimates are used for policy simulations. Given multiple nutrient deficiencies, income-related policies are better suited than price policies to improve nutrition. While consumer subsidies for maize increase calorie and mineral consumption, they contribute to a higher prevalence of vitamin deficiencies.

THE HEALTH EFFECTS OF A FISCAL FOOD POLICY AgEcon
Salois, Matthew J.; Tiffin, J. Richard.
This paper examines the health effects of a fiscal food policy based on a combination of fat taxes and thin subsidies. The fat tax is based on the saturated fat content of food items while the thin subsidy is applied to select fruit and vegetable items. The policy is designed to be revenue neutral so that the subsidy exactly offsets the revenue from the fat tax. A model of food demand is estimated using Bayesian methods that accounts for censoring and infrequency of purchase (the problem of unit values is also discussed). The estimated of demand elasticities are used to compute nutrient elasticities which demonstrate how consumption of specific nutrients changes based on price changes in particular foods from the fiscal policy. Results show that while the...
