Monetary policy

Profit is one of the most important factors influencing economic decision making, the changes of which depend on various factors. Banks, as one of the most important business units, have a special reliance on the concept of profitability and their performance is significantly influenced by macroeconomic conditions. Government economic policies are placed. This paper aims at applying the panel regression model to study the effect of monetary policy on the profitability of banks from 2006 to 2018 using data from 30 provinces to find appropriate policy recommendations for decision-making in the banking system. The research method was the use of GMM regression technique in the context of combined data. According to the results, the performance and profitability of banks are improved by the implementation of expansionary monetary policy. However, bank lending and price inflation have a negative effect on banks' performance. According to the results of this study, control variables such as the amount of overdue claims and GDP also had a positive effect on the performance of banks. Also at the macro level, with regard to the negative effects of Expansion monetary policy and the growth of liquidity, with the controlled implementation of Expansion monetary policy, it helps to improve the performance of banks in the banking system.

Monetary policy is one of the important economic policies that affect the macro variables of every country. One of the composite variables that are affected by the monetary policy is the FCI. This study aimed to measure the effect of monetary policy through different channels on the FCI of Iran. Using time series data from 1991-2023 and the econometric method of PCA, the FCI was first calculated. The effect of monetary policy on the FCI of the country using the Markov-switching (MSIHA(2) AR(2)) model was calculated and estimated. The results of the estimation of the Markov-switching model indicate that the studied period can be divided into two regimes of zero and one. So that 1% increase in the FCI in regime zero will lead to a 0.02% return of the FCI in the next month and a 0.36% increase in the next two months. In addition, the increase in the FCI in regime one will lead to a 0.08% return of the FCI and a 0.10% increase in the next two months. In addition, the volume of money in regime zero and regime one also positively and significantly affects FCI.

This paper has investigated the role of search and matching frictions in a monetary model and examined if the Friedman rule, advocating a rate of deflation equal to real interest rate, is still right. We defined a dynamic programming problem in which money is situated in the model by cash in advance constraint, and used a numerical method (value function iteration method) to solve the pre-mentioned problem. Also, in this paper, the concept of the homogenous agent is substituted by the heterogeneous agent, and there are two groups of agents, namely unemployed and employed agents. The difference between the two divergence groups is indicated by different constraints in this study. According to our model, the Friedman rule will not maximize the aggregate welfare of the assumed society with this new friction. It is noteworthy that the parameters of the numerical model have been derived from the United States economy and the essay is theoretical. The results can be applied in different economies with their specific parameters. Also, the study offers some implications to central banks. JEL Classification: E52, E24, C78.

This study aimed to evaluate the role of the banking system and, in particular, the monetary policies and provision of bank facilities, in recession and boom periods on employment in the labor market. In this research, the most important variables were employment, bank and financial development index, volume of facilities provided to the private sector, bank facilities rate, wage rate, workforce, capital stock, liquidity, degree of economic openness, inflation rate, direct foreign investment, government expenditures, and oil revenues. The research tool was the smooth transfer regression (STR) model applied to evaluate the relationship between the variables during 1989-2016. According to the results, there was a nonlinear correlation between banking variables and employment. In the section of the nonlinear model, it was observed that with a 2.87% increase in the inflation rate, the banking indexes (e.g., money market development, the volume of facilities granted, and liquidity) had a significant and different impact on employment. In this respect, it was found that the indicators of monetary policy and bank facilities had a weak effect on employment of the country, demonstrating the improper association between monetary policies and workforce supply and demand in the labor market of the country.

In recent decades, many countries have improved systematic control over monetary policy and stabilized inflation at moderate levels. There is a great literature on how to conduct a monetary policy. A lot of macroeconomists (for example Taylor, McCallum, Woodford and others) proposed specific monetary policy strategies, regimes and rules. This paper considers a dynamic stochastic general equilibrium (DSGE), and two basic factors have been applied. The first one is a belief that monetary policy has impact on real economic activity in the short run. This effect comes from the presence of rigidities, which give rise to non-neutral effects of a monetary policy. The second factor is a considerable improvement under theoretical frameworks used for monetary policy analysis. The research also presents a sensitivity analysis of the optimal rules to deep structural parameters and investigate properties of an optimal simple rule with respect to prevailing type of shocks. Finally, the study highlights how an optimal policy rule depends on model structure, on the model calibration and nominal rigidities. According to the research findings, based on the theoretical expectations, the effect of a positive shock inflicted on the government investment leads to increase and gradual accumulation of fixed capital formation in the public sector. Among estimated parameters consumption is first affected and reduces, then employment increases consequently, finally production will also be affected. Also with the shock of oil revenues, increased oil revenues results in public investment at first, because the increase in oil revenues, the government increases development expenditure. Though increase in development expenditure is more than Increase in current expenditure. Enhancing development expenditure & construction spending causes total spending increase and as a result of increased production of oil income, consumption and total investment will rise. This increase leads to inflation too. Though by increasing the inflation resulted from oil revenues, the monetary authority will react through reducing the growth rate of the monetary base.

This paper attempts to compare a Markov-Switching Dynamic Stochastic General Equilibrium (MS-DSGE) model by including deep habits consumption to a MS-DSGE model without deep habits. It is concluded that the deep habit adjusted model with regime switching is able to fit the Iranian data better. The results of estimating parameters indicate that deep habit formation, together with the persistence of habit stock, are significant parameters. The results also confirm that current and future consumption demand, expected marginal cost and stock of habits are effective driving forces in extracted New Keynesian Philips Curve considering deep habits. However, in contrast with Ravn et al (2006, 2010) findings, it is shown that presence of deep habit consumption in the model for Iranian economy, cannot lead to reduce inflation in response to monetary shock while the amount of increase in inflation in response to monetary shock in the model with deep habit is less than inflation increase in model without deep habits. Furthermore, in response to fiscal shock in the model considering deep habits, the negative effect of wealth could not be compensated in Iranian economy. Therefore, consumption begins to decrease in response to fiscal shock, although these reduction in the model without deep habits takes more longer than in the model with deep habits.

The aim of this study was to assess the performance of the Iranian currency exchange market by analyzing the dynamic conditional correlation (DCC) between the Iranian currency exchange rate and the free market exchange rate of the US dollar in Iran. This analysis was conducted for both the same day and with a one-day lag, spanning from June 20 to October 30, 2022. The results of the study indicate that the DCC for concurrent days (denoted as dcc0) stood at 48%. Meanwhile, the DCC for the Iranian currency exchange rate with a one-day delay compared to the free market US dollar exchange rate in Iran (referred to as dcc+1) was 17%, and the DCC for the free market US dollar exchange rate with a one-day lag behind the Iranian currency exchange rate (referred to as dcc-1) was 35%.
