One of the important factors in solving the economic problems of countries is the expansion and development of investment; but this alone is not enough and, considering the limited financial resources, in addition to the issue of investment development, increasing efficiency is also an important issue. The present study was conducted with the aim of examining the impact of economic policy uncertainty on the efficiency of investments of companies listed on the Tehran Stock Exchange. The present study is an applied study in terms of its purpose. In terms of the method of collecting the required data, it is a descriptive-correlation study and, since it deals with expressing the cause and effect relationships between the research variables, it is of the post-event causal type. The statistical population of the study includes all companies listed on the Tehran Stock Exchange. Also, in order to analyze the shocks of macroeconomic policies, the structural vector error correction model has been used. The collected data was classified using Excel software and all the variables required for analysis were calculated using this software. Then, statistical analyses of the research variables were performed using Eviews and JMulTi software. In order to examine the effects between variables, the structural vector autoregression (SVAR) model was used. The model and related statistical tests were analyzed using EViews software. |
