    Journal PapersJournal of Applied Economics Studies in Iran , 2021 February 17, {Pages }


    According to the financial literature, the agency problem can affect bank loans when there is information asymmetry. In this regard, the contract between the bank and bank agents, who are involved in the lending process, is considered crucial along with monetary incentives. Career concerns and characteristics of bank agents can also affect these agents' performance, and effectiveness of the bank’s monetary incentives. Based on the results of empirical and theoretical studies, the performance-based incentives or rewards (as opposed to lending-based incentives) and more career concerns of bank’s agents leads to an increase in the quality of lending, albeit by reducing risk-taking leads to reduction in the lending measure (profitability) o

    The 2007 financial crisis clearly demonstrate the role of capital assets in the emergence of economic fluctuations and business cycles. Physical assets with a dual role as a factor in production and use as collateral to obtain loans from the banking system in two separate channels affect the real sector of the economy and lead to intensification of product fluctuations and business cycles. Emprical evidence of Iran’s economy indicates that the price of capital assets has been rising and fluctuating over time for various reasons, the most important of which are the role of oil revenues and related shocks. Accordingly, with regard to the collateral effect channel, there is an expectation that by creating a positive oil shock and increasing

    Journal PapersIranian Economic Review , 2020 January 11, {Pages }


    Discount rate is one of the important variables in the intertemporal analysis which makes it possible to compare the current and the future values, and enables the policymakers to make better decisions. In this context, the discount rate is a vital variable for the accurate evaluation of economic projects. Considering the different approaches which governmental and private sectors use to assess the governmental projects, a separate discount rate is used, which is called social discount rate (SDR). In this paper, by using the structural equation model, we have estimated the SDR trend in the Iranian economy during the period of 1996–2016. To do that, by extracting the influencing and consequence factors of SDR (as latent variables), we used

    Journal PapersReview of Managerial Science , 2020 September 11, {Pages Jan-43 }


    The existing literature is still inconclusive on whether momentum exists and whether momentum strategy profits are affected by macroeconomic variables. The aim of the present study is two-fold. First, we examined the existence of the momentum by studying the strategy profits in six oil-rich developing countries in Middle East including Iran, Saudi Arabia, Bahrain, Qatar, the United Arab Emirates, and Kuwait using the double-sort strategies. Our findings show that there is a momentum profit over short-, mid-and long-term periods in all countries. After selecting the best combinations of information sets and holding lengths for each country, by adding the oil price and the exchange rate, and adjusting the models proposed by Chordia and Shivak

    Background: Supplier-induced demand (SID) refers to the concept that healthcare providers may deliver services to patients that are not medically necessary. An estimation of the extent to which this event has occurred can be insightful for policymaking and guiding health systems. This study aimed to investigate the extent to which SID presents itself during diagnostic MRI (magnetic resonance imaging) for primary breast cancer.Methods: In this cross-sectional study, data were obtained using questionnaires from a random sample of 310 cases. To identify patients who were candidates for undergoing a necessary diagnostic MRI, we employed the international clinical guidelines with the confirmation of our expert panelists. With their assistance, a

    Context: Supplier-induced demand (SID) is an essential concept in health economics related to the diagnosis of different types of cancer and related expenditures. The current review considered studies on induced demand in cancer diagnosis. Evidence Acquisition: This systematic review investigated the induced diagnosis of cancer in four well-known databases (Scopus, Science Direct, Web of Science, and PubMed) from January 1980 to July 2019 using the keywords “induced demand,” “cancer,” and “diagnosis”. References of the studies found through the original search were also considered for analysis. Results: No studies focused on SID in cancer diagnosis could be found, thus indicating a significant deficiency in the discussion of SID

    In the Iranian economy, a part of the financial needs and liabilities of the government is always financed by the Central Bank. With an increase in the government debts to the Central Bank, monetary policy gets passive and implemented in line with fiscal policies. Consequently, the functions of the monetary policy are disrupted, and it deviates from its goals. This can have undesirable impacts on the macro-economy. So, this study aims at the macroeconomic effects of the government debts to the Central Bank in Iran during the period of 1973-2017. To this end, a SVAR model is used. The result of the research showed that the government debt to the Central Bank has had no significant effect on the ratio of aggregate demand to aggregate supply,

    Journal Papers , Volume 11 , Issue 42, 2020 March 20, {Pages 138-171 }


    Given the development of machine learning models in predicting financial data in recent years, this study introduces a combination of Deep Learning Network and selected GARCH family models to predict short-term daily returns of the Tehran Stock Exchange Index. The most important feature of the deep learning network is that it can adapt and adjust itself to the volatility of market variables without being limited to specific models. In this study, short-term and long-term memory based neural network (RNN-LSTM) models are used for deep learning network models and GARCH and EGARCH models are used in its structure. Also, the two independent variables of oil price and dollar rate in the structure of the hybrid model help to predict the financial

    Given the importance of financial development to achieve sustainable economic growth, the main objective of this study is to investigate the effect of economic openness (financial and trade openness) on financial development (with emphasis on institutional components) in two groups of oil and non-oil developing countries. In this regard, the Panel ARDL method has been used for the period 2000-2017. The estimated results indicate a positive and significant effect of financial openness on financial development in the oil developing countries and its negative and significant impact on financial development of the non-oil developing countries in the long run. Also, the results show that trade openness has a significant and positive effect on fi

    Iran has been increasingly affected by the process of globalization and developments of new technologies in recent decades. In the course of these influences, changes in the lifestyles of the people and other dimensions of their lives have been created. The reduction of gender gap, the increase of the rate of women’s participation, and the reduction of fertility rates, etc. can be considered as its consequences. Therefore, the study of this relationship of Information and Communications Technology (ICT) and its changes and severity for future policies can be very important, including the link between fertility and ICT and employment and ICT. This study examines the cyberspace deployment effect on women’s employment and fertility rate in

    In recent decades, due to the growing importance of the role of human capital in economic models, the importance of the issue of education has risen in economics literatures. This paper aims to investigate the determinants of educational costs in micro level (household) in Iran. The determinants affecting educational costs are categorized at four levels: household characteristics, child characteristics, head characteristics and mother characteristics. The effect of these categories is estimated thorough a censored Tobit model for Iran household survey in 2016. This model has been chosen so that zero cost in some cases can be reported. The result shows that urban residency and having girl Childs (versus boy) are context factors that increase

    Journal PapersEnergy Efficiency , 2019 January , {Pages 24-Jan }


    Today, electrical energy plays a major role in production and consumption and is of special importance in economic decision-making process. Being aware of electrical energy demand for each period is necessary to correct planning. Therefore, the forecasting of electricity consumption is important among several economic sections. Besides the traditional models, in this paper, we offer a hybrid forecast approach that combines the adaptive wavelet neural network with the ARIMA-GARCH family models and uses the effective exogenous variables on electricity consumption. Based on this approach, two hybrid models are proposed. To assess the ability of the proposed models, we forecasted the daily electricity consumption by the hybrid and

    During past years, economists have been endeavoring to determine both relationship and causality direction between real macroeconomic and nominal economic variables. In this regard, many studies have been carried out on the relation between money and inflation, resulting in the introduction of the notion of money neutrality which implies that permanent change of money supply just affects the nominal variables and has no lasting and real effect on production and employment. Furthermore, even when constant changes of money growth have no real impact whatsoever (except on real monetary equilibriums); money is stated to be super neutral in the long run. Although the majority of economists (with disparate schools of thought) concur with long-ter
