Abstract
The paper aims to estimate Sudanese household food demand by focusing on six aggregated food items. The items are cereals (sorghum, millet, wheat), meat and chicken, milk and eggs, vegetables (okra, onion, tomato), staples (sugar, salt, oil), and caffeine intake (tea and coffee). The paper used the Quadratic Almost Ideal Demand System (QUAIDS) model to estimate Sudanese household food demand. The results showed that demographical variables have an impact on households’ expenditure shares. For example, the results revealed that married respondents spend less from their income on cereals and staples compared to unmarried respondents. Also, men spend more from their income on caffeine compared to women. The results of the Marshallian own-price elasticities showed that all food items in Sudan are price inelastic indicating that price changes have a small impact on quantity demanded. Also, expenditure elasticities show that all food items in Sudan classified as necessities, except for meat and chicken.
