  The purpose of this paper is to measure the average share of information and communication technology in long-term productivity growth and as well as the increasing intensity of ICT index in Iran's manufacturing industries at the level of double-digit codes (ISIC). For this purpose, the expanded growth accounting model in the period2005-2018was exploited. The research findings revealed that : The effects of ICT has a significant positive effect on the average long-term productivity growth in Iran's manufacturing industries. ICT's share of long-term productivity growth in The most intensive contribution of ICT has been recognized for coke and related products, electrical equipment and chemicals and related products. This effect has shown more than any other manufacturing industries in Iran and this amount has also improved over time. The lowest share of ICT in productivity growth in the long run is related to furniture, clothing and machinery and not classified equipments. The results  also showed that the average value of increasing ICT intensity index is insignificant meaning the more  and with increasing intensity of ICT use, the more intense effect on productivity growth increases.

  AbstractIn this paper, the asymmetric effects of stock market shocks on the exchange rate in Iran were evaluated using the daily data from 20/03/2016 to 21/06/2023 using cointegration and APARCH methods. The evidence shows that both shocks (positive/negative) are repeatedly found in the Iranian stock market. Out of 2642 days, 1601 days of the market had negative returns and 1041 days had positive returns. In 511 days the market has fluctuated more than one standard deviation (big shocks). Estimates show that there is a strong long-term relationship between these two markets. The findings showed that the reaction of exchange rate to the positive and negative shocks of the stock market is asymmetric and has a long-term effect on the exchange rate. The behavior of the exchange rate towards negative and positive impulses is cyclical. The big negative shocks in the stock market gradually increase the return of exchange rate and eventually this effect does not disappear and puts the exchange rate at a higher level. But the effect of the big positive shocks in the stock market on the exchange rate is dampening. Negative shocks have a greater impact on conditional volatility compared to positive momentum. Also, the fluctuation of the stock market shows a very stable pattern. Keywords: shocks, stock market, exchange rate, asymmetric, APARCH.JEL Classification: G19, N25, F31, C58 Manuscript profile

  3 - Bootstrap-DEA efficiency: Radial and non-radial approaches in the banking industry

  This article aims to assess the efficiency of 15 stock market banks over the period 2014-2022. Utilizing non-parametric radial efficiency (Debreu-Farrell efficiency) and non-radial efficiency (Russell efficiency) methods, we analyze constant, non-increasing, and variabl More

  This article aims to assess the efficiency of 15 stock market banks over the period 2014-2022. Utilizing non-parametric radial efficiency (Debreu-Farrell efficiency) and non-radial efficiency (Russell efficiency) methods, we analyze constant, non-increasing, and variable return-to-scale technologies. Recognizing limitations within radial methods, bias-corrected technical efficiency is also estimated using bootstrap data envelopment analysis. Radial analysis reveals inefficiency among all banks except for the Middle East bank. The average Debreu-Farrell efficiency stands at 77% under constant return to scale and 82% under variable return to scale, while the average Russell efficiency is 58% and 67% respectively. These results suggest slack in Debreu-Farrell efficiency. Bootstrap efficiency findings reveal underestimation in both radial and non-radial efficiency, thereby overstating actual efficiency levels. Bias-corrected radial technical efficiency scores from the bootstrap approach indicate inefficiency across all banks, with Dey and Sarmaye banks exhibiting particularly poor performance. Thus, adopting appropriate strategies such as non-performing loan management, increased non-interest incomes, and reduced operational costs is imperative to enhance efficiency. Manuscript profile

  4 - Effects of Industrial Localization Economies and Urbanization on Economic Growth: The Evidences of Iranian Markets

  In the field of regional economics, the effects of industrial agglomeration are defined as the product efficiency derived by industrial interdependency and the firms are usually considered to be external economies in decision-making process. The aim of this paper is to provide a model for new economic geography based on endogenous agglomeration theory of Krugman (1991) in Iranian markets. Hence, by estimating Solow generalized function, the effect of urbanization and industrial agglomeration is examined during 2000–2010 in Iran provinces. The results indicate that core-periphery theory is not correct in the provinces of Iran; so that spillover effects of outside market are significant and positive, while home market effect statically is not significant. So, developing the road transportation infrastructures and strengthening the markets linkages play a determinant role in the appearance of spillover effect of outside market and then on the growth of the provinces.

   Mixed strategy Nash equilibrium (MSNE) is a concept commonly used in Game Theory. The game between the kicker and goalkeeper in soccer penalty kicks is a real game used to examine the application of the MSNE concept or the rate of its accuracy. The data were collected on the direction of kicks and jumps in 106 penalties kicked in Premier League of Iran and the predictions of the model analyzed. The observations represented that given the probability distribution of kick direction, the optimal strategy for goalkeepers is to stay in the center of the goal; but the goalkeepers, almost always, jumped to the right or left. Finally, the “left-left” pattern is the most frequent and have the greatest number of observations. Manuscript profile

  This paper investigates the impact of spatial aggregation of industrial activities on manufacturing industries productivity growth of Iran's provinces during 2004-2013, using cross-section data and dynamic pooled regression by Generalized Method of Moments (GMM). To measure industrial aggregation Ellison Glaeser (EG) index was used. The findings support the “Williamson hypothesis”, that is, aggregation of industrial activities has positive effect on productivity growth only up to a certain level of development. By improving infastructures and markets expand, congestion externalities vary in the development phases and it can result in more dispersion in economic activities. Namely, aggregation accumulates human and physical capital and this accelerates economic growth. Manuscript profile

  The factors ‘shares are constant in Solow growth accounting approach. The purposes of this paper are evaluating the effect of capital income share change on economic growth, implementing the growth accounting approach to calculate total factor productivity (TFP) considering that capital income share to be changed; and finally, estimating the effect of capital income share and it’s variation on TFP growth.   For this reason, the data of value added, capital stock, and labor compensation with constant values at 2011 as well as labor forces data of manufacturing industries in 31 Iran’s provinces during 2000-2014 have been collected. Findings show that the capital income share variation had positive effect on income per capita in provinces ‘manufacturing industries with value 11.5 thousand Rials. The growth accounting results indicate that classic factors contribution (labor and capital stock) of economic growth was 11.4 and 200 percent, respectively. Moreover, capital income share variation and Zuleta TFP contribution of manufacturing industries economic growth are 30 and -141 percent, respectively. Finally, outcomes of panel least squares (PLS) estimation show that capital income share variation has significant and positive effect on TFP growth, but income share level doesn’t significant effect during the considered period. In fact, a one percent increase in capital income share will increase the TFP growth by approximately 2.6 percent; which these are due to variation of factor abundant ratio and biased technological change in provinces ‘manufacturing industries of Iran.        Manuscript profile
