According to the findings, it has been observed that there is causality from defense expenditures to gross domestic product, that is, the change in defense expenditures affects gross domestic product. Similarly, causality has been determined from defense expenditures to external debt. Therefore, it is possible to state that the change in defense expenditures will have an impact on foreign debt. In this respect, the findings are in agreement with the literature. The increase in defense expenditures will increase the production of the defense industry, the export of this production will result in a resource inflow to the country and the gross domestic product will increase. On the other hand, in some countries, defense expenditures will be financed by debt from foreign sources, which will increase foreign debt.Publication The determinants of incentives implemented in the electrical energy sector: an empirical analysis on the Turkish energy market(Informa UK Limited, 2023-08-02) Feti Erbaş; Yaşar Köse; Rıza Bayrak; Ceyda Aktan; Köse, Yaşar; Aktan, Ceyda
