Abstract: | The recent empirical food demand studies on Sub-Saharan Africa show significant advances in demand specification and methodology, especially in the application of less restrictive and theoretically consistent flexible functional forms. The findings to date establish some broad patterns on effect of income, household demography and life cycle, location, and prices on food demand patterns. However, the numerical values of the demand estimates are less generalizable because of an insufficient number of data points to separate the true demand component from other confounding factors, which are linked to differences in modeling and estimation of demand relations. The priority for future research is to generate sufficiently detailed demand estimates that have a high utility for disaggregated policy analysis, but are based on a theoretically consistent and comparable methodology. |
