Estimation the Almost Ideal Demand System for Egyptian potatoes Exports in the most Important Foreign Markets

Export is a basic pillar upon which the economic launch is based in providing permanent sources of foreign exchange, and a means to reduce the deficit in the Egyptian trade balance. The problem of the research is that the Egyptian potato exports are unstable, which the study attributes to the strong competition in global markets. Therefore, the research aimed to estimate the demand functions for potato exports using the semi-optimal demand model in the Russian market, the Greek market and the Italian market during the period (2005-2020). The results of the study indicate that the most important importing countries for Egyptian potatoes in terms of quantity are Russia, Greece, Lebanon and Italy, with a relative importance of about 33.98%, 9.15%, 8.17%, and 6.99, respectively. The results of the Russian market showed that the price elasticity of demand amounted to -0.787, which means that it is a commodity with inelastic demand in this market, and the spending elasticity reached about 0.487%, which indicates that it is a normal commodity. The price elasticity of demand in the Greek market amounted to about -1.827%, meaning that it is a good with elastic demand, and the spending elasticity reached about 0.771%, which indicates that it is a normal good. It shows the complete acquisition of Egypt for the Lebanese market. While the price elasticity of the Italian market's demand for Egyptian potatoes amounted to about -8.76%, meaning that it is a commodity with elastic demand, while the spending elasticity reached about 0.429%, meaning it is a normal commodity. study recommended studying the export prices of competing countries to increase the competitiveness of Egyptian potatoes. necessity of working to preserve the competitive advantage of Egyptian potatoes in the main markets, with interest in regulating the supply of the crop in the economic markets. need to work on opening new markets for competition by paying attention to quality specifications and the required consumer tastes.
