Iranian Economy
حوزه های تخصصی:
This paper intends to address the problem of inflation in less developed, and transitional economies, where the institutions of market is not fully developed. It is argued that the conventional Neo-Classical policies based on rigid Monetarist views fail to properly address the problem in less developed economies, and as a result its policy prescriptions are bound to fail. In These economies the issue of persisting inflation and unemployment, presents a serious challenge, which requires a more realistic approach in studying the problem.
Considering the case of Iran, following a brief review of the background of a dualistic structure in the economy, the nature of recent price changes and distribution patterns is analyzed for various income groups. Then it is argued that while the current price and subsidy reform could lead to higher economic efficiency, a significant success in this program requires however, supplementary macroeconomic reforms in several areas, towards the goal of greater economic growth and a more competitive position in global markets.
A Long Run Structural Macroeconometric Model for Iran(مقاله علمی وزارت علوم)
حوزه های تخصصی:
We employ the modelling strategy of Garratt, Lee, Pesaran and Shin (2003a) to estimate a structural cointegrating VARX* model for Iran in which core macroeconomic variables of the Iranian economy are related to current and lagged values of a number of key foreign variables. The long run macroeconomic relations for real money balances, interest rates, output, prices and exchange rates are identified and tested within this framework over the period 1979Q1-2007Q4. We make use of generalised impulse response functions to analyze the dynamic properties of the model following a shock to exogenous variables (oil prices and foreign interest rates). We also examine via the persistence profiles, the speed of adjustments to the long run relations following a system-wide shock. The results show that money demand relation and UIP-PPP (international parity conditions jointly) are not rejected within the model. Furthermore, these two long run relations have well-behaved persistence profiles in which the effects of system wide-shocks on the long run relations are transitory and die out eventually. However, both UIP-PPP and the money demand relations exhibit sluggish rates of adjustments to shocks. We also provide evidence for the excessive importance of oil price shocks for Iranian economy in our impulse response analysis.
The Impact of Exchange Rate volatility on Banking Performance (case of Iran)(مقاله علمی وزارت علوم)
حوزه های تخصصی:
Banks play an important role in the Iranian economy which has a bank-based financial system. We examined the impact of exchange rate volatility as a determinant of banks' performance. In recent years, the exchange rate has been volatile in the Iranian economy and have an adverse effect on banks' performance. This study, investigate the issue for the period 2007-2017 for 14 Iranian banks. Exchange rate fluctuations are derived by GARCH method and the effect of its fluctuations on bank performance examined using panel data method. In order to evaluate banks' performance, we used two criteria, namely liquidity and profitability. Estimation of econometric model using panel data by random effects indicated that exchange rate volatility has a negative and statistically significant effect on banks' capital return ratio. Exchange rate volatility is also a determinant in increasing the ratio of lending to total bank deposits, as it increases the financial gap and creates the credit risk that the gap entails.

Inflow and outflow of oil revenues: Scenarios for National Development Fund of Iran(مقاله علمی وزارت علوم)
منبع:
Iranian Economic Review, University of Tehran, Vol.25, No.4, Autumn 2021
Resource-rich developing countries are forced by economic fluctuations due to international commodity price movement. One way to reduce the volatility adverse effects is to establish institutions such as Sovereign Wealth Fund. However, the way this fund is managed is important. Iran, as a resource-rich developing country, suffers from economic fluctuations. In order to manage resource revenues, National Development Fund (NDF) has been established. In this paper, using DSGE model, we examined different scenarios for managing fund resources. A scenario, without any stabilizer Fund and two different scenario for National Development Fund. In the second scenario, NDF has a role like the one in Sixth Development Plan. In the third scenario, all oil revenues are deposited to NDF and a part of the fund as much as interest rate in the OECD countries plus 70% of long run oil revenues invested in the economy. The Results indicated that the management of oil revenues by the Fund, in which the inflow of oil revenues into the economy follows the commitment, is an appropriate policy to reduce the economic fluctuations in Iran.
A Nonlinear Approach to the Effect of Oil Shocks on Iran’s Economy(مقاله علمی وزارت علوم)
حوزه های تخصصی:
This paper aims to show the asymmetric effect of oil shocks on Iran’s economy. It uses nonlinear time series models to investigate the asymmetric effect of oil shocks on resource allocation in Iran’s economy. The results show that adverse oil shocks have been more persistent during the last decades and severely negatively affect resource allocation in Iran’s economy. Different oil shocks have different implications for importing and exporting countries, and the rigidity of state fiscal systems in exporting countries causes adverse oil shocks to be more persistent. The oil economy’s response to positive and negative oil shocks depends on the structure of the economy. The government budget and trade balance have significant implications for the effects of oil shocks on oil-exporting economies. The government budget is highly dependent on oil revenues, so in the case of adverse oil shocks, the pass-through exchange rate will cause high inflation because of foreign exchange shortage and overshoot in the exchange rate.
Competition and Market Power in the Manufacturing Industries: A Comparative Study(مقاله علمی وزارت علوم)
منبع:
International Economic Studies, Vol. 51, No. 2, 2021
This paper examines the gap between marginal cost and the price of 22 manufacturing industries in Iran at ISIC 2-digit level and 32 industries at a 3-digit level during 1995-2015 compared to selected countries. It examines the gap by using the Hall-Roeger model. We found that in garments, basic chemicals, non-metallic mining, and refined petroleum products, the price and marginal cost difference are high and in tobacco industries are low. In 3 out of 22 industries at ISIC 2- digit level and in 11 out of 32 industries at 3-digit level, Iranian industries have higher markups and a significant gap between price and marginal cost than Japan, Germany, France, and the United Kingdom. Also from 32 industries in ISIC 3-digit level and 22 industries in 2-digit level, Iran has the lowest mark-up in the tobacco industry with 1.03 and in chemical products with 2,33, has the highest markup.

تخمین سهم عوامل مؤثر بر سوءتخصیص سرمایه: شواهدی از کارگاه های صنعتی در اقتصاد ایران(مقاله علمی وزارت علوم)
حوزه های تخصصی:
در این پژوهش به تخمین سهم عوامل مختلف مؤثر بر سوءتخصیص سرمایه فیزیکی در اقتصاد ایران پرداخته می شود. بدین منظور از یک مدل تعادل عمومی استفاده می شود که در آن عواملی همچون هزینه تعدیل سرمایه، نااطمینانی (در سطح بنگاه) و ناهمگنی در قدرت بازار و توابع تولید بنگاه ها وجود دارند. با تخمین پارامترهای مدل به روش گشتاورهای تعمیم یافته، می توان سهم هرکدام از این عوامل در سوءتخصیص را محاسبه کرد. در این پژوهش از داده تابلویی کارگاه های صنعتی ایران در آخرین بازه در دسترس (1382 تا 1392) برای محاسبه گشتاورها و تخمین پارامترهای مدل استفاده شده است. نتایج نشان می دهد می توان تا بیش از 80 درصد سوءتخصیص مشاهده شده در اقتصاد ایران را به سه عامل هزینه های تعدیل، ناهمگنی در تابع تولید و ناهمگنی در قدرت بازار بنگاه ها نسبت داد. در مقایسه با مطالعات مشابه، نقش هزینه های تعدیل در ایران به طور قابل توجهی بیشتر از سایر کشورها است. همچنین نشان داده می شود سوءتخصیص طی بازه زمانی مورد مطالعه افزایش یافته و این امر ناشی از افزایش نقش اختلال ها در اقتصاد بوده است.
