Abstract

The research attempts to answer the following question: “Can food sovereignty from sunflower oil be achieved in Egypt in the long term?” Or “Is it possible to achieve a long-term balanced relationship between the quantity of sunflower oil production and its price in Egypt?” The research relied on the use of the Toda-Yamamoto methodology to estimate long-term causality between the quantity of sunflower oil production as a dependent variable and the real wholesale price of sunflower oil, As an independent variable. the research found a two-way causal relationship between the wholesale price of sunflower oil in logarithmic form as a dependent variable (LNRP) and the quantity of sunflower oil production in logarithmic form as an independent variable (LNPRO) in the long run. It has also been shown that the short-term imbalances between the two variables are decreasing. By about 72% annually, which means reaching a state of equilibrium in the long term within approximately a year and a half.
