the relationship between oil revenue, exchange rate, and M2 on the CPI and PPI, over time of 2005:1-2022:1, was investigated in Iran with QARDL method used. The results showed that, in the short run, all the variables had an asymmetric effect on the CPI and the PPI. oil revenues, in the long run, from the quantile of 0.05 to the median, the impact of the variable on the inflation would be increased, and then its impact would be decreased. also, in the long run, the effect of the increase on the PPI is greater than the consumer price index. In the long run, the effect of exchange rates on the CPI and the PPI was nonlinear while being symmetric. because from the quantile of 0.2 to 0.8, its effect proportionally increased and then decreased. also, regarding the M2, the results showed that this variable on the CPI and the PPI had an asymmetric effect, in the short run. in this way, from the middle quantile to the quantile of 0.9, its effect was positive and significant, and in the long run, the results confirmed its positive effect on inflation in all quantiles; although, its effect on the PPI was asymmetric.

Despite the recession in global financial markets, the Tehran stock Exchange experienced significant growth during the COVID-19 outbreak. Therefore, this article tries to solve this puzzle by analyzes the effect of three Coronavirus waves on the total index of Tehran stock Exchange, its sub-indices, and the different industries with daily data of Iran and the regression method with multiple breakpoints. The results show that each wave of COVID-19 have different effects on the stock market. COVID-19 in the first wave had a negative effect on the index of industries such as refined petroleum, chemical, Metals and transportation but had a positive effect on industries such as medicine and food. But in subsequent waves, response of different industries to the new pandemic is complicated for two reasons. First, the nominal exchange rate has positive and significant effect on main industries such as motor mehicles, banks, refined petroleum, metals and chemical (which have a considerable weight in the Tehran Stock Exchange), can show the positive trend of the index, especially in the first and second waves of the COVID-19. Second, the government's manipulatian in raising the stock prices of these main industries to finance its budget deficit caused the Tehran Stock Exchange index to move in the opposite direction in some periods in response to the Corona virus.

This paper studies the main fiscal determinants of central bank credibility (CBC) from 1990 to 2014. Covering 25 inflation-targeting (IT) economies, we mainly focus on sovereign debt holders and fiscal rules since adopting the IT framework. As the CBC indicator is highly concentrated in the right tail of the distribution, the mean-based approaches are incapable of unearthing the fact that the effect of fiscal factors may be asymmetric across the distribution of the credibility index. In departing from the problem, we use a quantile regression method to estimate parameters over the entire conditional distribution of CBC. The asymmetric response using the quantile regression is state-dependent and conditional on the credibility distribution. Having provided a comprehensive survey on the fiscal factors potentially related to the credibility in the literature, we find that fiscal rules are almost prominent at the lower quantiles while debt holders' composition is strongly significant at the upper tails of CBC distribution. These findings are further supported by the slope equality tests, discussed in Koenker & Bassett (1982). These results could be attributed to the more sensitivity of the private sector expectations to the debt holders’ composition. Therefore, central bankers could reduce public expectations by taking into account the non-linear impact of fiscal factors on their credibility.

This study has investigated the effect of Central Banks transparency and independence on productivity growth during 1981–2018 in Iranian economy. Transparency and independence of central bank were measured by Dincer and Eichengreen index and Cukierman index respectively. The variables in this study which are in annual form are central bank transparency, central bank independence, GDP growth, productivity growth, inflation rate and free trade. Auto-Regressive Distributed Lag (ARDL) method was used for model estimation. The coefficient of the error term is negative, statistically significant and equal to -0.308. It can be concluded that 30% of the short-run disequilibrium is adjusted to achieve long-run equilibrium. The results show that the transparency of the central bank has a positive effect and the coefficient is equal to 0.36 on productivity growth in the short-run, but it is effective on productivity growth in the long-run equal to 1.08. In the short-run, the independence of the central bank has a negative and significant effect on productivity growth equal to -3.09, but in the long-run the effect of this variable is positive and equal to 1.09.

This paper is an endeavor towards investigating the potential role of deposit market structure as a distinct channel for (monetary, fiscal, and regulatory) policy transmission mechanism. In doing so, we have developed the core idea in a rational expectation partial equilibrium setup incorporating the possibility of contagion risk in the banking system. This has enabled us to build up more sensible analytical findings within a tractable structure which is capable of making diverse equilibria spotted in some empirical evidence. The setup/paper lays down conditions under which one could expect Nash equilibria involving, inter alia, “limited price war”, “deposit rates rat race”, “bank run”, and “systemic banking crisis” followed by incidents of “banking panic”. This multiplicity in equilibria is the result of interaction between the deposit market structural characteristics and policy commands due to externalities originating from strategic complementarity/substitution among the rivalry banks in the market. Further the paper explores the allocation and stabilization efficiency implications in terms of conceivable equilibria for deposit rates, deposit market share, expected net returns, expected markup, and the level of expected effort of banks operating in the banking system with an emphasis on the role of equity capital in between.

Credit is the basis for financing and stimulating investments. However, excess credit can be the source of systemic risks and financial crises. In this paper, using Iran’s credit data from 2000 to 2019, the Basel credit gap was calculated as a recommended indicator for measuring excessive credit. We perceive that in the years in which the economy is suffering from currency overvaluation; for example, from 2005 to 2011, excess credit is noticeably visible. Moreover, in periods with a fair exchange rate, for instance, from 2000 to 2004, no excess credit was observed. Using capital buffers is an essential regulatory policy to reduce the risk of excess credit. So, the counter-cyclical capital buffer was calculated for all these periods. We also found that Basel’s credit gap has good power in predicting exchange crises in Iran. It seems that the root cause of excessive credit and foreign currency jumps should be sought in the exchange rate-based stabilization plan in Iran (exchange rate anchor). Nonetheless, policymakers can reduce the probability and severity of crises by strengthening the bank credit sector’s regulatory systems and using the proposed buffers.

Recent financial literature argues that there are gender differences between men and women, impacting financial decision making and performance. This paper, using data related to micro-loans of an Iranian private (commercial) bank between 2012 and 2018, investigates the effects of the characteristics of the members of the branch credit committees (BCCs), especially gender, on loan quality. Because, the dependent variable (loan quality) is a discrete ordinal variable and based on the Brant test’s result the proportional odds assumption was violated, the generalized ordinal logit model was used. The results of this paper show that increasing the presence of women in BCC improves the quality of micro-lending. Based on the literature and related studies, a potential explanation for these results is that increasing the number of women in the BCC improves the compliance of the decision-making and lending processes with the credit guidelines and recommendations, increases the BCC risk aversion, and reduces the agency problem by improving monitoring in the BCC. Moreover, the results also show that the quality of micro-lending management by BCCs with a higher average age is poorer than that of a younger BCC, and the higher education of the BCC members improves micro-lending quality.

After the financial crisis of 2007-2009, in which liquidity problems led to insolvency and consequently the bankruptcy of many large banks and financial institutions such as Lehman Brothers, Basel Committee on Banking Supervision introduced liquidity requirements for the most part to reduce the possibility of bank insolvency caused by liquidity shocks. This research develops an agent-based model of a banking system to be used to analyze the impact of the liquidity requirements on the solvency position of banks. The model devises a banking system with 12 heterogeneous banks in which banks perform their traditional activities namely taking deposits and making loans. Banks can fulfill their liquidity needs by engaging in interbank lending, selling their securities, and using central bank lending assistance. The model aims to study the behavior of different banks in response to imposing liquidity requirements. This model is calibrated using the data of Iranian listed banks during 2018-2020. Liquidity requirements are measured using liquidity coverage ratio, and the solvency position of a bank is measured using the capital adequacy ratio. The results of the simulations demonstrate that as liquidity requirements increase, the solvency position of some banks improves, some banks deteriorate, and some remain unchanged. Regarding this reaction among other various factors, profitability, inflow, and outflow of liquidity, and finally, the outflow rate parameter play an essential role.

In this study, we design a structural macro model for Iran economy in which there is a dual exchange rate regime, namely, official (fixed) and unofficial (floated) rates. The official rate determined by the central bank whereas unofficial rate set in the free market. The structural parameters of the designed model is estimated using quarterly data in the 1991- 2019 period, and Bayesian method. The main finding of this paper is that establishing a dual exchange rate regime cannot prevent the negative effects of exchange rate dynamics on macro variables. Therefore, it is better to abandon this strategy and instead, central bank put forward optimal respond to exchange rate dynamics. To do this, we derive an optimal policy rule for the central bank and show that the best policy is assigning equal weights to inflation rate and exchange rate in loss function and an active respond to both inflation rate and exchange rate in the policy rule.
