FOOD DEMAND PATTERNS IN GHANAIAN URBAN HOUSEHOLDS

This paper analysed food consumption patterns in Ghanaian urban households by comparing food commodity budget shares and estimating price and expenditure elasticities for eleven food commodity groups across different income groups. The Linear Approximation Almost Ideal Demand System (LA/AIDS) was applied to the data. Demand for most of the food commodity groups was found to be elastic. The study concluded that generally, across income groups, food commodities respond negatively to changes in food prices and that cereals/bread, roots/tubers, vegetables, meat and fish will remain an important component of urban household food expenditure. Generally, household demographic characteristics such as age, gender and household size had significant effects on urban food demand patterns
