ANALYSIS OF THE COVID-19 TO EFFECT OF TURKEY XGIDA INDEX WİTH VAR MODEL (13.03.2020 - 20.11.2020)

Abstract

With the pandemic process caused by the COVID-19 virus, the measures taken by the countries have caused production to come to a halt all over the World. As a result, the need for energy has decreased, and consumption has led to more food and health. Therefore, the XGIDA index in Borsa Istanbul was used as a variable in the study. This information was analyzed in the light of the studies discussed in the framework of the VAR model that XGI what degree the number of cases of COVID-19 index was impressed to what extent Turkey and give response to unexpected changes in these variables. For the action-response graphs, the XGIDA index gives a positive (increasing) response to the number of COVID-19 cases until approximately the 3rd period, while there is a negative (decreasing) reaction in the following periods and then towards the balance. On the other hand, while the number of COVID-19 cases gives a positive (increasing) response to the XGIDA index until the 4th period, a reaction towards balance is observed in the following periods. According to the results of the analysis of variance decomposition, 100% of the changes in the XGIDA index in the 1st period are due to their previous values, and 0% are due to the COVID-19 case number variable. In the 10th period, 92% of the changes in the XGIDA index are caused by their previous values, while approximately 8% are due to the COVID-19 case number variable.
