Terrorism is an action aimed at providing illegal threats, violence and fear to achieve certain goals. As a result, terrorist acts result in economic costs in two dimensions, direct and indirect. Direct costs arising from terrorism include loss of life, costs associated with injuries, damaged property and infrastructure, and other business and trade losses. Along with this, however, there are indirect costs that are felt more intensely afterwards. Indirect costs arise at the economic, financial and fiscal scale, and the effect is felt for a long time. These effects are seen in many areas such as economic growth, foreign direct investment, capital flows, foreign trade, tourism and, unemployment. If all these effects can prevent the consequences, it is possible to say that efforts will be made to combat terrorism.
