Societal Implications of Fiscal and Monetary Policies: Does Good Governance Matter?, Taylor & Francis Ltd, ss.141-152, 2026
There are many different monetary policy tools used by the central bank. These tools can have a direct or indirect effect on the performance of renewable energy investments. Renewable energy projects are of vital importance for the social and economic development of countries. Therefore, necessary actions should be taken in a timely manner to increase these investments. However, there is no consensus in the literature on which monetary policy instrument is more effective on the development of these projects. The main purpose of this study is to determine the monetary policy instrument that is most effective in increasing renewable energy investments. In this process, decision making trial and evaluation laboratory (DEMATEL) technique is used to calculate the importance weights of the selected variables. In this study, firstly, a criteria list is created that has four different factors that are required reserve ratio, discount rate, open policy transactions, and currency exchange rate. After that, 12 different questions are created by using these four criteria. These questions are asked to three different experts. The findings indicate that discount rate is the most critical monetary policy instrument to improve the renewable energy projects. Open policy transactions play also an important role in this regard. Nevertheless, required reserve ratio and currency exchange rate have lower significance weights.
