During the past few decades, governments around the world have been allowing market forces to play an increasing role in the electricity sector. The transition from the monopoly framework has led to the restructuring of the electricity market in leading economies to achieve greater competition and efficiency. Government of Iran also has been implemented a daily market for the competition of power plants in electricity sales based on supply bidding mechanism in order to guarantee reliability and efficiency. The basis of this mechanism is the Klemperer and Meyer (1989) study. This paper first introduces the supply bidding model of Holmberg (2009). Then current bidding of selected power plant in the Iranian electricity market compare with the optimal bidding. For this purpose, the demand uncertainty structure is estimated at the specified days in different seasons. Finally the optimal bids of Holmberg model are estimated. The results indicate that supply bids of the selected public power plant are suboptimal and can be improved by using the model. Alternative payment approach called uniform price can also be replaced to compare tow mechanisms.

The main purpose of this article was testing the relation between competition and innovation in Iran’s manufacturing industry. To meet this ends the data of 130 Iran’s 4-digit industries over the period of 1996-2013 were used. Also, this article sought to analyze this relationship by using a panel smooth transition approach. The results indicated that, clearly there was the nonlinear relationship among variables and by increasing concentration until threshold value 0.267 the research and development intensity increased but after this threshold value, its effect decreased. Moreover in the second model by increasing research and development intensity till the threshold value of 0.38 percentage the concentration increased and after that, this impact has been decreased. In addition, only in 6% of Iran's industries competition and innovation was high but, in most industries by increasing competition, innovation were declining. Overall, there was an asymmetric relationship between competition and innovation and in most industries the intensity of research and development expenditures were low. So, in Iran’s industries, the inverse U relation between innovation and competition confirmed.

The micro and macro approach to the exit firms of Iranian industriesThe purpose of this study was to investigate the effect of factors affecting the exit firms at three levels of firm, industry, and environments (macro) using the logite panel model for the period of 1975-1393. The results of this study have shown that at the firm level, productivity has a significant effect on the exit of the firm, in other words, with the increase in productivity, the probability of exit from the firm decreases. At the industry level, the rate of entry and the index of concentration have a significant effect on exit, and the increase in the rate of entry will result in an increase in the probability that the exit firm will from the industry. so the structure of the market moves into competition, the probability that a firm will leave the industry will increase. At macro level, economic growth, inflation, concessional facilities and population size had a significant effect on exit. Increasing economic growth, giving more bank loans to the manufacturing sector and increasing the population will reduce the probability of exit, but rising in inflation will help increase exit probability.

The purpose of this research is to explore strategies for developing knowledge-based employment in the country. The present research is applied to the research purpose, applied-development, and in terms of the method of research, it is a qualitative and quantitative mixture. In the first stage, using the Grounded Theory, a conceptual model has been used to explain the strategies for developing knowledge-based employment in the country. In the qualitative section, experts familiar with the issue of developing knowledge-based knowledge formed the statistical sample of research. According to the adequacy of sampling and theoretical saturation, 15 people were selected through purposeful sampling and bullet-shot sampling method. To analyze the data, a three stage, open, axial and selective coding process has been used. In the quantitative part of the research, the statistical population of the study included all the managers and experts of the companies of the students. The statistical sample of the research was based on the recommendations of the use of confirmatory models of 250 people. In order to collect data, a researcher-made questionnaire was used based on the sub-categories and the concepts derived from the qualitative research stage and based on the paradigm model. A confirmatory factor analysis has been used to analyze the data. The results of a small part of the research show that all validation models have been formulated appropriately.

The regions in a country respond differently to monetary shocks. The purpose of this paper is to analyze the effects of monetary shocks on employment in regions with non-systematic mechanism of monetary transmission. To achieve this purpose, we used TVP-FAVAR approach to describe monetary shocks in the thirty provinces over 1384:1- 1394:4. The results show that there are different responses to monetary shocks in Iranian provinces. Also, the response of each province is different in terms of time, and the economic conditions play main roles in response of province to monetary shocks. The findings of this paper represent evidences of asymmetric effects of monetary policies in Iranian regions. We suggest the central bank should consider the regional differences in policy making.

In recent years, the role of stock market in the economy of Iran is growing. Therefore, it is important to recognize the factors affecting to this market. Changes in the money supply can be one of this factors, so this study investigates long run neutrality of money in the stock market of Iran. In this regard, quarterly data of monetary aggregates M1, M2 and the real stock indexes that is total index, industrial index and financial index has been employed in this study over the period ranging from the second quarter of 2001 to the second quarter of 2015. In this paper the order of integration of the series for money supply and real stock indexes has been identified by using Hegy[1] test. The Fisher-Seater (FS) methodology has been used to test the neutrality of money in this research. The empirical results indicate that permanent changes in money supply (defined as M1) don’t affect the real stock indexes. Similar results were also obtained for money defined as M2. In general, the results support that money is neutral in the stock market of Iran.

The theoretical and empirical literature of behavioral economics shows that people in their decision making have a behavioral and cognitive bias. Therefore, the actual behavior of individuals is not always consistent with economic and rational human behavior. Two of the most important behavioral biases that can play an important role in people's environmental attitudes and behavior are the hot-hand effect and hyperbolic discount rate. In this study, we tried to study the effect of these two biases on the attitude and environmental behavior of individuals in Tehran using the semi-experimental approach and difference in difference regression. In this regard, a sample of 90 subjects was divided into two groups (control and treatment group). The data were collected through a questionnaire in two stages before and after the test. And the difference in difference regression was done. the results showed that: First, the training and awareness of behavioral and cognitive bias improve the environmental attitudes and behavior of individuals. Therefore, policymakers should consider information and education about cognitive bias. Second, demographic variables such as level of education, age, gender, and marriage do not have a significant effect on differences in environmental attitudes and behaviors of individuals.

Comprehensive banking model, with its main focus on addressing all kinds of customer financial needs, comes from combining commercial banking with investment banking. Comprehensive banking is a kind of customer-centric approach to banking, which has been considered in the Western banking industry for the past two decades, and is referred to as banks, which have a wide range of financial services, including commercial, investment, insurance, advisory and Others offer their customers. The purpose of this paper is to investigate the asymmetric effects of banking sector development on the profitability of banks in the country and in particular the National Bank based on a comprehensive banking model with the approach of the non-linear model of Markov regime change. For this purpose, the time series information of 1396-1388 was used. Based on the results, it was observed that the interest rate variables of the participation bonds, the industry concentration index, the ratio of cost to income, the ratio of loans to total loans, equity holdings to total assets had a negative and significant effect on profitability and The variables of the ratio of loans to total assets, total assets, customer deposits to total debt, income variation, inflation rate, and economic growth rate have had a positive and significant effect on the profitability of the National Bank. The variance of variables in regimen one, the regime of low volatility, is less than the two regimes. This is consistent with the theory, since it falls in the time of low volatility in the market, and macroeconomic variables and indicators such as prices are stabilizing.

The main purpose of this paper is to investigate the effect of monetary policy on the value added in the basic metal Industries sector is based on the use of positive mathematical programming during the periode of 1990 - 2017. For achieving this, at first the long-run relationship between variables has been estimated by using of ARDL approach and then, the scenario designing and sensitivity analysis has been implemented through PMP model.The results of this study showed that the decreasing and incremental policies of monetary variables (liquidity and bank interest rate) in different scenarios have an effect on the added value of optimizing that subsection. Also, an important indicator of this method is to calculate the optimal value added of each sub-section in its base year and its targeting capability in some other scenarios. For example, in the first scenario, in the case of 5, 10, and 20 percent reduction in liquidity, value added will increase by 4, 9 and 18 percent in Basic Material Production industries. In this scenario, the drop in the policy variable will also increase the bank interest rate by as much as 3, 7 and 15 percent in the added value.

One of the features of a financial market, the stock market in particular, is its affectability from other financial and nonfinancial markets. So, perceiving the relationship between the stock return and other markets can be helpful for investors to create an optimal portfolio. The present study is aimed at investigating the dynamic conditional correlation (DCC) between the returns on the domestic and foreign markets in monthly data (oil , gold, industry, exchange rate, and base metals including total metals, copper, steel) and returns on the stock price index in Iran over the period March 2001- to April 2017 using the DCC-FIAPARCH approach.The results of paper indicate a statistically significant and positive DCC coefficient between the metals, industrial products and copper returns with stock returns. As a results,it is not possible to put each of these assets with the stock in an identical situation (purchase or sale), but instead they should be always in the opposed situations for the purpose of risk control.
