1 - Welfare costs of inflation using frictional unemployment in Iran:General Equilibrium Model approach

The model also features a cash-in-advance constraint. To achieve this goal, through the utilization of calibration and sensitivity analysis in the steady state, the findings indicate that both employment and production are contingent on the elasticity of labor supply and the elasticity of vacancies in job matches. Depending on these two parameters, they may exhibit an increase in response to an escalation in the inflation rate. Additionally, the three-month optimal inflation rate in a stable state is determined to be 4.66%. The welfare gains, derived from reducing the three-month inflation rate from its current level of 5.3% to the optimal rate in a steady state, is calculated to be 0.0031% of total consumption. Therefore, based on the results, it is suggested that in inflation reduction policies, the effects of this reduction on welfare are taken into consideration, and special attention should be paid to the area of business investment by giving tax incentives, especially tax credits..

2 - The non-linear effect of liquidity and debt repayment on banks profitability in Iraq

For this purpose, the Panel Smooth Transition Regression (PSTR) method was employed to examine the nonlinear impact of liquidity indicators (including the ratios of current assets to total deposits, total loans granted to total deposits, and total loans granted to total assets and debt payment capacity indicators (such as the debt ratio and interest coverage ratio) on asset returns from 2011 to 2020. The findings revealed a nonlinear effect of all calculated indicators on asset returns. The magnitude and manner of the independent variables' influence on asset returns varied at different levels, with noticeable distinctions in the effect before and after the threshold value of 1.0586. In light of these results, bank policymakers can strategically select an optimal liquidity level to enhance bank profitability based on asset returns. Manuscript profile -

3 - The effect of industrial concentration and capital goods import on the energy consumption intensity in Iran’s industries

Industrial concentration index has been calculated using Herfindahl-Hirschman method and relative entropy. In this research, the panel data method and the fixed effects model were used to estimate the coefficients of the models. The research findings indicate that between 2002 and 2018, industrial concentration and import of capital goods have a positive and statistically significant effect on the intensity of energy consumption. So that, one percent increase in the share of the industry in the market, increases the intensity of energy consumption between 0,089 to 0.203 percent. Also, the price of energy carriers has a negative effect on the intensity of energy consumption. Considering the inverse relationship between the price of energy carriers and energy intensity and the low elasticity of the price, it is necessary that incrementally raise the energy prices for industries logically causing environmental pollution to decrease their energy intensity. It is suggested that capital goods enter industries that have low energy consumption. Manuscript profile -

Empirical studies reveal that both visible and invisible elements play a role in shaping FDI in any given country, often eluding straightforward inclusion in economic models. This research, recognizing the significance of this subject, delves into the impact of economic sanctions on the attraction of foreign direct investment in Iran over 44 years, employing a fuzzy approach. The findings underscore the substantial and moderate economic sanctions, characterized by high and robust fuzzy coefficients, exerting a notable negative effect on the allure of foreign direct investment in Iran. Additionally, the study reveals that variables such as the budget deficit, inflation rate, mild economic sanctions, adverse exchange rates, alongside factors like gross domestic product, economic openness, domestic interest rates, foreign direct investment with interruptions, governance quality index, and the effective tax rate on company profits, have exhibited a positive influence on the attraction of foreign direct investment in Iran.

For this purpose, based on this approach, the countries with real exchange rate stability were selected and among them, the weighted composition of the countries that had the most similarity in the situation before the real exchange rate jump of Iran was estimated. Therefore, two groups were formed, including the group of selected countries named artificial Iran and the other, real Iran. Finally, the results of the estimates of these two groups were compared and analyzed. The results indicate a 15% difference in the immigration process of artificial Iran and real Iran. The analysis of the results showed that the impact of the jump in the real exchange rate on the migration flow in Iran was positive. Based on the results, it is suggested that policymakers pay attention to the destructive effect of real exchange rate jumps on the flow of migration from the country and adopt appropriate economic policies to stabilize the real exchange rate.

6 - Analysis of agency conflict with emphasis on aspects of earnings management, audit quality, and cost of equity: Game theory approach
Zahra Moghadam Hamzeh Didar Kiumars Shahbazi Ali EbadianThis article aims to describe and explain the strategic behavior of managers and shareholders in the interactive conflict environment of joint-stock firms using the tools of game theory, specifically through signaling games.

Managers, considering the quality of internal controls, engage in both deceptive and informative earnings management strategies. Shareholders then respond with strategies involving high or low capital costs and opt for either high or low-quality audit services. The findings of the research outline the theoretical conditions necessary for establishing balance in strategies such as deceptive earnings management with high capital costs and deceptive earnings management with high-quality audit services in environments characterized by weak internal controls. Additionally, it highlights the conditions required to establish equilibrium in strategies like informative earnings management with low capital costs and informative earnings management with low-quality audit services within environments boasting strong internal controls.
