The results of investigation from estimated equations indicate that non-duty and duty offered facilities has had a positive and significant effect on the added values in economic areas.Among these, the share of offered facilities to services, industry and mines, construction, housing and agriculture have had the greatest effect on the added values respectively. Prioritization of sectors based on economic return to scale and the amount of optimal allocation of bank credit can have favorable effects on the value added of various economic sectors in Iran.

In this study 62 explanatory variables were introduced into the model between 1370: 1 and 1395: 4 and, using the Bayesian averaging model approach, 12 non-critical variables that were effective on the financial crisis were identified. According to the results of the results, it can be stated that the financial crisis index in Iran's economy is a multi-dimensional problem, as variables related to fiscal policy; monetary policy and foreign exchange policy affect this index. Based on the results of the Autoregressive Vector Models Variable-Time Parameters, it was also observed that the effect of selected variables on financial crises in Iran over the course of time has had different effects and in recent years the intensity of the effect of selected variables has been strengthened. One of the fundamental solutions is that policies that reduce inflation uncertainty, such as the fiscal and monetary discipline of the government and the central bank, reduce crisis expectations by stabilizing the currency and currency markets can reduce crisis uncertainty.

3 - Determining the Optimal Interest Rate and Its Effects on Iran's Economy: An Application of Optimal Control Theories

Taking into account Iran’s economic, social and cultural planning, its economic growth rate is considered 6%, and the inflation targeting 10% in the present research. The results show that in order to achieve the describe economic growth rate of 6% in a year and the inflation targeting rate of 10%, the optimal interest rate needs to be 5.2%. By notice that the bank average interest rate for Iran has been 14.3% in the same period, it is suggested that bank interest rate decreases. This matter will increase investment and ultimately expand production and economic growth in the Iranian economy. Manuscript profile -

4 - Investigation and identification of possible conflicts in the implementation of macroprudential policies with the objectives of monetary policy (output and price stabilization) in the Iranian economy using the DSGE approach"

However, under certain conditions, the implementation of these policies may have negative effects on the output gap and price stability, which are the goals of monetary policy. In this paper, by designing a a closed dynamic stochastic general equilibrium model for the Iranian economy in the period 1369: 1 to 1399: 2 and macroprudential tools loan-to-value restrictions and countercyclical capital buffer and shocks including productivity, bank capital and monetary policy shocks is used and the conflicts (increasing variance ) resulting from the implementation of macroprudential policy on monetary policy objectives was examined.The results show that with the occurrence of shocks, the implementation of loan-to-value ratio requirements does not conflict with production and inflation, and with more response of this tool, the variance of production and inflation reduced monotically, indicating a complementary relationship of this macroprudential tool with monetary policy objectives. Therefore a policymaker can use this macroprudential tool with less concern.However, the requirement of countercyclical capital buffer after the occurrence of these shocks is initially in conflict with price stabilization and output, which with a more severe reaction of this macroprudential tool reduces inflation and output fluctuations and reduces its adverse side effects. However, the exception is the variance of inflation in the monetary policy impulse, which increases with the intensification of the loan-to-value ratio, and with the intensification of countercyclical capital buffer,inflation is initially decreasing and after reaching its minimum value, it rises. . The results of this study can be useful for how macroprudential and monetary policies are organized and how to coordinate between these two policies. Manuscript profile -

With the rise and growth of Islamic banking, various studies and studies have been conducted to analyze the performance and regulatory mechanisms of this industry. The rules of the Basel 2 agreement are among the most important in the international agreement, which is designed to provide banking security. Among the issues raised in this agreement, the observance of minimum capital adequacy has received much research attention. Given the inherent differences and constraints facing Islamic banks in Iran, Basel Committee's capital ratios may not necessarily be appropriate for this banking system. Then, by modeling its impact on bank profitability as the most important motivational index of banks, its optimal value for the Iranian banking system is determined. The results show that the designed model is well able to explain the relationship between capital adequacy and profit efficiency and the optimal capital adequacy ratio for optimizing bank profit efficiency was estimated at 12.5%.In the same way that healthy and efficient banks can be effective in economic growth, their unhealthy and poor performance can also lead to financial and economic crises. The WFTC has been reviewing and proposing capital requirements since 1988 and, most importantly, observing the minimum capital adequacy of banks. Calculation of capital adequacy requires consideration of capital and risk weighted assets. Due to the significant difference between the methods of financing and the use of funds and the type of contracts and payloads in the Islamic bank with the conventional bank, it is necessary to calculate and determine the minimum capital adequacy for an Islamic bank after identifying and classifying various types of assets, liabilities and capital And the amount of risk associated with each of them, taking into account its specific financial features. Therefore, this research intends to assess the suitability of a set of the most important indicators of banking healthy indicators, namely, capital ratios. To this end, the ratio of capital ratios (tire1+tire2) to risk weighted assets with technical efficiency of Islamic banks of Iran is reviewed. After calculating the technical efficiency index of banks by CCR and BCC, eight panel data regression models for the period 2003-2015 were estimated for 21 banks and more than 190 statistical samples. The results show that all four capital indicators have a positive and significant effect on the technical efficiency of the banks. However, tire1 capital to total assets ratio is the best explanatory variable among capital ratios for banking performance. Manuscript profile -

9 - Consequences of the policymaker's reaction to speculative attacks in the foreign exchange market: The role of the quality of political institutions

Given the incomplete information of the central bank about the severity of the attack, it is necessary to be aware of the relative consequences of each of the reactions in the unit of economic indicators as a result of each of its possible responses. This study examines these consequences in the unit of changes in GDP and inflation for developing and emerging countries and in the period 1960 to 2018 examines the role of the quality of political institutions between selected countries. The results obtained from the instantaneous reaction functions for GDP and inflation as a result of three possible types of central bank responses including intervention with success, intervention with failure and non-intervention in the foreign exchange market show that in the absence of quality indicators of political institutions Low cost will not face a clear and unequivocal answer. In terms of the quality of political institutions, intervention in the foreign exchange market is preferred in the group of countries with high quality political institutions due to the increasing reputation and credibility of the policies announced by the Independent Central Bank. Findings show that in the group of countries with moderate quality of political institutions, non-intervention of policymakers in the foreign exchange market is associated with increased GDP growth and low inflation and is preferable to intervention in the foreign exchange market. In the group of countries with low quality political institutions, intervention in the foreign exchange market is less risky than non-intervention, and the low-cost response is to defend the national currency.
