  The spread of volatility between financial indices indicates the process of information transfer between markets. Despite the relationship between financial markets, the information created in one market can affect other markets as well. Therefore, the main purpose of this study is to investigate the volatility of energy and steel prices and the experimental test of inter-market volatility spillover. To do this, the monthly data of steel and energy price (oil and gas) during 2009 to 2019 were collected from valid databank using VECM and GARCH Family and VAR model and ICSS algorithm were analyzed by considering and without considering structural failure.Then, the causal relationship between them is examined through Granger causality test. The results show that there is volatility in the energy market (oil and gas) as well as the steel market during the studied time period. Results also show that the price of steel as well as its return and index are changed significantly by energy price effect. However, there is a causal link between energy prices and steel products and these results are consistent with the theoretical basics of the study and review of literature. Manuscript profile

  The main objective of this study is to investigate the relationship between monetary policies, capital structure and risk-taking of listed banks in Tehran Stock Exchange. In this study, to measure the monetary policies, the indicator of legal reserve rate have been used. The sample consists of 21 banks listed in Tehran Stock Exchange in the period from 2012 to 2018. In this study, the data were extracted from the Rahavard Novin 3 software and then classified by Excel software, and after calculating the variables, finally, through Eviews10 software, the multivariable regression model and panel data was used to test the hypotheses. The results showed that there is significant negative relationship between monetary policies and banks' risk-taking with in 95% confidence level. In addition, other findings indicated existence of a significant positive relationship between monetary policies and bank capital structure. However, the research results show that there is no significant relationship between bank capital structure and banks' risk-taking. Manuscript profile

  The role of the capital market is fundamental and decisive in the economy of all countries [6]. Studies show that in the capital market, prices are determined based on macroeco-nomic variables[2]. Accordingly, In this study is to provide a model for measuring the impact of economic policy uncertainty (EPU) on information asymmetryn.The research method is applied and has been made to present a model for measuring the effect of EPU on information asymmetry in the EVIEWS12 and MATLAB2021 software environment. The research time period is determined from 2011 to 2020 and 101 companies are selected based on the applied restrictions to estimate the model. In this study, 40 variables affecting EPU are entered into the According to the results of BMA, the most important variables affecting the EPU is provided[2]. Based on the principal components approach, the EPU index is calculated using the most important variables affecting this variable. Then, with the GARCH model, the uncertainty part of the EPU index is extracted, and finally, using the powerful nonlinear TVPFAVAR model, the shock caused by the EPU variable on the information asymmetry indices in the research period is analyzed. The results show that the shock caused by the fluctuation of the variable of EPU has increased the index of information asymmetry in recent years. Based on the results, EPU shock on the index of information asymmetry has had a stronger effect on in the short and long term information asymmetry than the medium term. Manuscript profile
