Abstract: | Using the Almost Ideal Demand System (AIDS) model incorporating habit formation with and without homogeneity imposed on the system, the author estimates the effects of factors that influence consumption patterns for five food commodity groups in the Republic of Cameroon, viz. cereals, roots and tubers, milk and dairy products, meat, and fish. Annual time series data on household expenditures, prices and urbanization are used to estimate the parameters of the AIDS model. The data come from several sources and cover the period from 1975 to 1993. The analysis indicates that changes in real per capita income have significant effects on budget shares only for meat, fish, and milk and dairy products. From expenditure elasticities, meat and milk and dairy products are classified as relative luxuries, while fish, cereals, and roots and tubers are classified as relative necessities. Fish, cereals, roots and tubers, and milk and dairy products are close substitutes for meat but remain complementary to each other. Changing habits significantly affect budget shares for meat, fish, and roots and tubers, while urban growth leads to an increase in budget shares for all commodity groups.
