A Food Demand System Estimation for Uganda
AbstractThis article estimates a household demand system for Uganda from cross-sectional household survey data. More specifically, a 13 item two-stage demand system model is estimated for rural and urban households separately where the main second-stage is represented by a Quadratic Almost Ideal Demand System which accounts for socio-demographic household characteristics and censoring and focuses on food items. Elasticities are calculated for three household expenditure groups as well as for the aggregate. We find that food expenditures tend to be more elastic for poorer households than for richer ones. All foods are generally price inelastic and price elasticities tend to decrease with rising expenditure level. A number of substitutional and complementary relationships between food items are identified.
