In the study, the effects of macroeconomic variables such as economic growth, imports, exports, current account deficit, inflation and unemployment on foreign direct investments are discussed using Cointegration and Granger Causality Tests for the 1980-2020 period. According to the findings obtained as a result of the analysis, it has been determined that there is a bidirectional causality relationship between inflation and foreign direct investments in the long run which are among the macroeconomic variables selected within the scope of the study. On the other hand, there is a unidirectional causality running from economic growth to foreign direct investments. Similar findings were obtained as a result of the Impact-Response Analysis.
