Aim of this study is to examine the substitution and complementary relationships of Egyptian exports from fresh and frozen potatoes in the global market. The study focused on investigating current situation of Egyptian exports from fresh and frozen potatoes at world market in comparison to its situation at Egyptian market. Hereby, demand on Egyptian fresh and frozen potatoes was assessed and time trends of price developments were statistically estimated and their relationship to global prices were analyzed.   Most important results of existing study are summarized in the following points   The analysis of Egyptian and global export prices for fresh and frozen potatoes during the time period 2000- 2012 showed increasing trends of both, which is statistically significant. The results showed increasing demand on frozen at the cost of fresh potatoes. This also matches with same development at global market. The development of export prices of Egyptian potatoes (fresh and frozen) matches with the development of prices at global market. The relationship between Egyptian and global export prices has shown linear and stable between 2000 and 2012. It seems also that export prices of frozen Egyptian potatoes much more stable than those of fresh potatoes. By studying for Stability Coefficient to export prices for fresh and frozen potatoes during the time period 2000- 2012 showed that export prices of frozen Egyptian potatoes much more stable than those of fresh potatoes. Canada, France, Germany, and Netherlands are the most export countries that competing with Egypt on world market of potatoes, particularly fresh. When computing the price competitiveness of Egyptian fresh potatoes, the result shows that Egyptian potatoes are highly competing with open-mentioned European export countries. The price competitiveness of Egyptian frozen potatoes is relatively higher when comparing to other competitive markets of Belgium, Canada, France, Germany, etc. This shows great opportunity for Egypt for expanding its exports from frozen potatoes in nearly future. Using regression analysis of time series data, the study of demand for Egyptian exports of fresh potatoes indicated that Egyptian potatoes is considered as necessary good for consumers of open-mentioned countries based on estimated price and cross elasticities. It has also proven that there is a substitutional relationship between Egyptian fresh and frozen potatoes. An important result that insure the importance of re-drawing export policies of potatoes exports in Egypt.

The crops of the legumes, especially the domestic beans, are considered the most important food groups due to their high nutritional value, in addition to their importance in improving soil properties. The state aims to encourage the expansion of the faba bean production to fill the food gap and also to supply hard currency. Egypt is one of the most important importing countries for beans. The legume crops are considered the most important food groups because of the high nutritional value. The bean is a strategic commodity for the Egyptian citizen. The study aims at reducing the imports of the Egyptian faba bean. Egypt's demand for faba bean, estimation of the competitive advantage of the main exporting countries of Egypt, and the comparative advantage index. The study found that the quantity of Egyptian bean imports increased by an annual rate of about 2.41 thousand tons. This increase is statistically insignificant at 0.05 level, and the value of Egypt's imports of faba bean has taken an upward trend at an annual rate of about 7 million dollar This increase is statistically insignificant at 0.05 level, and the price of Egypt's imports of faba bean has taken an downward trend at an annual rate of about 14.5 dollar/tons This increase is statistically insignificant at 0.05 level and the study of the geographical distribution of imports of Egyptian fab beans shows that the United Kingdom, Australia and France Representing 88 % Of Egypt's imports of beans. The percentage of Egypt's imports of faba bean decreased at a growth rate of 14%. The volume of exports of the United Kingdom and France decreased by 38% and 96%, respectively, while Australia increased its exports by 5% The elasticity of demand functions also showed that the elasticity of the price demand of Australia's export price indicates that the de mand is inelastic and Egypt needs this commodity from the Australian market, and the income elasticity shows that the commodity is poor by increasing income. The explanation of the elasticity of the demand for the price of France's exports shows that the demand is inelastic and Egypt needs this commodity from the French market. It is also evident from the income elasticity that the commodity is normal, i.e., the increase in income is the required quantity of the commodity, while the elasticity of the price demand of the UK export price shows that demand is not Flexible and Egypt needs this commodity from the British market, as evidenced by the income elasticity that the commodity is poor by increasing the income decreases the required quantity of the commodity. The study of forecasting Egypt's imports of Australian beans shows that the volume of imports of beans is expected to increase from about 136 thousand tons in 2018 to about 245.6 thousand tons in 2025. It is expected that the quantity of imports of British beans will increase from about 58 thousand tons 2018 to about 277.3 thousand tons in 2025. It is expected that the quantity of imports of French beans will fall from about 0.334 thousand tons in 2018 to about 45.9 thousand tons. It is also expected that the quantity of Egyptian imports of beans will increase from about 410 thousand tons in 2018 to about 500 thousand tons in 2025, is expected to decrease the amount of domestic production of beans from about 144 thousand tons in 2018 to about 16 thousand tons And it was found that the available amount of consumption is expected to decrease from about 281 thousand tons in 2018 to about 72.5 thousand tons in 2025.
