The main purpose of this study is to test the effectiveness of capital market efficiency through the mediating variable of political cycles based on the theory of constraint on the rate of total stock returns for manufacturing companies listed on the Iranian Stock Exchange. In this regard, first, the theoretical foundations and internal and external background of the research have been examined and in the next step, a sample of 178 companies from manufacturing companies based on the fixed effects method, and for two research models the estimation of panel econometric models has been done. In the next step, the research model was estimated by considering the variables of political cycles for the period of 1384 to 1392 (political period of fundamentalism) and also the period of 1392 to 1398 (non-fundamentalist political period). The results showed the negative effect of the political cycle variable in the fundamentalist period and the positive and significant effect of the political cycle variable in the non-fundamentalist period on the stock return rate. In the end, suggestions were made to improve the stock rate of return of listed companies based on the results. Manuscript profile

The main purpose of this study is to evaluate the performance of Bank Melli in supporting the production of domestic goods by providing banking facilities for the purchase of goods based on the Kaplan and Norton Balanced Scorecards model. To achieve this goal, the theoretical foundations and related internal and external studies have been examined. In the next step, based on the research model and its dimensions, a research questionnaire was designed and distributed among a sample of 150 managers and experts of Bank Melli and examined and descriptive and inferential statistical analysis (testing of research hypotheses). The results show that there is a significant difference between the current and favorable situation of purchasing domestic goods by providing facilities for purchasing goods of Bank Melli in all four dimensions of the balanced evaluation model (value, finance, work processes, and education and learning).
