Estimation of food demand parameters in Kenya. A Quadratic Almost Ideal Demand System (QUAIDS) approach

Author

Abstract

Food security is a key topic for the Kenyan economy. This report contributes to the improvement of the understanding of the demand-side drivers of food demand patterns and their evolution in respect to changes in income and prices in this country. The report provides a new estimate of expenditure and price elasticities for goods consumed by households in Kenya. The estimation approach employed is based on the Quadratic Almost Ideal Demand System (QUAIDS) which depicts the demand system in a flexible way by imposing less restrictive marginal expenditure shares. The estimations are performed for 4 different levels of commodity grouping and also at the regional level, yielding significant income and price elasticities at all levels. These estimations will contribute to improve the overall food security analysis and in particularly can be useful to enhance the demand side of economic simulation models largely employed by JRC.
