Consumer Demand for Major Foods in Egypt
运用线性近似理想需求系统模型估计埃及主要食品的需求方程，得出自身和交叉价格弹性及支出弹性，为转型期食品与农业政策分析及预测提供参数依据。
This study provides information on the structure of the consumer demand for major foods in Egypt. The information is in the form of key parameters for consumer demand systems. The modern theory of consumer behavior is the basis for estimating systems of demand equations. These systems yield estimates of own- and cross-price elasticities. The Linear Almost Ideal Demand System (LAIDS) model is applied in estimating a system of demand equations for food commodities. A full demand matrix results with a coherent and consistent set of price and expenditure elasticity estimates. Using the estimated own- and cross-price and expenditure elasticities, food and agricultural policies during the transformation to the market economy can be analyzed. A framework for utilizing the estimated demand parameters in forecasting is also presented.
