  Estimating the amount of market power and determining the market structure of various industries is one of the most important topics in microeconomics,because the amount of production and price of various goods and services is affected by the degree of monopoly and market power of that industry.The purpose of this research is to estimate the degree of agreement and the levelof market power of the insurance industry using the Hall-Roger approach in the form of supply and demand equations with the help ofpanel data using the two-stage least squares method.For this purpose,the information of27public and private insurance companies In addition to the large share of their financial market in employment, the insurance industry is closely related to the characteristics of savings and the level of economic development of countries, and as one of the tools of risk management, it provides the expansion of social welfare on the one hand, and on the other hand It leads to the growth of investment and, as a result, more production and economic prosperity.As expected,the research results indicate the mutual dependence of insurance industry companiesSo that more than 85%of the investigated insurance companies have been able to enjoy a significant profit margin by creating a gap between the price and the final cost.Also the calculation results related to theLerner index based on theHall model show the information related to the coefficient of heterogeneity among insurance companies.Iran insurance has the highest Lerner index with a coefficient of0.565andAsia,Dana andPasargad insurances are in the next ranks with0.419,0.248and0.182respectively, Manuscript profile

  The aim of this paper is to investigate the monopolistic power of Iran’s banking industry by parametric approach. For this purpose, the Lerner index was calculated in the bank deposits and loan markets using the Translog stochastic frontier cost function and using banking data including balance sheet and profit and loss statement of 33 banks during 2001-2014. The results showed that monopolistic power of banking industry in the loan market has decreased over time and competitive conditions somewhat have been improved, so that the Lerner index for loan market in 1380 has been decreased from 0.77 to 0.54 in 1393. However, the gap between price and marginal cost is rather high level. Also, the Lerner index of deposit market has been fluctuated between 0.5 and 0.33. Manuscript profile

  Abstract The main purpose of this paper is to evaluate the structure of banking structure in Iran and assess the monopoly power factor based on Bresnahan and Lau approach. In this paper, the market situation of monetary in Iran consisted 18 active banks are studied during 2007–2011. By the use of Bresnahan's market power model, it is found that there is no deposit market for pre-said banks in Iranian banking industry. The coefficients estimated by the research model have represented that the hypothesis of perfect competition without any withholding rates and deposit rates can be rejected for the entire market.

  Thisstudyexamines therole ofcorporate governanceandmarket disciplineon firm,s productivityinTehran Stock Exchange.Corporate governance has a significant effect on the firms total productivity and also a strong substitution between corporate governance and the market competition exists, this means that competition reduces agency problems, so when companies are facing extremely competitive manufacturing market, the corporate governance less effect on the firm,s total productivity is involved. We thus analyzed the financial information of 92 companies listed in the Tehran Security Bourse within the period 2004-2009. Required datausing library studies andsoftwareRahavardnovincollected.To test the hypothesis of correlation analysis and panel data and applying multivariate regression model with fixed effects with variable delay auto regression method in Eviews and SPSS statistical software was used. The research findings show that the positive and significant relationship between ownership concentration and total productivity has, also the relation between non-executive directors and total productivity is positive and significant and the relationship between board size and total productivity although is positive, but is not significant. Between corporate governance and total productivity characteristics, concentrator marketdiscipline, onlyrelationship between board size and total productivity debilitated andthe adjustment on other relationships did not exist.

  The most important role of bank deposits in the country's economy is to provide the necessary grounds for investment. Market power specifies how firms in a market influence prices, and reveals the level of competition in the market. Hence, the main aim of this paper is to investigate the impact of market power and macroeconomic variables effects on banking deposits in Iranian deposit money market using dynamic Bresnahan-Lau’s and weighted average least square approach for the 18 bank in the Iran industrial banking sector. Annual data for the period of 2008-2017 has been collected from annual financial statements of Iranian banks, Statistical Centre of Iran, Monetary and Banking Research Institute of Iran and central bank of Iran. The main empirical results indicated that the nominal exchange rate and liquidity money have negative and other extracted macroeconomics variables have positive and significant effects on the deposits of banking sector during the period of study. Moreover, the Dumitrescu-Hurlin panel Granger Causality tests confirmed the unilateral causality from macroeconomics variables and market power to the bank's deposits. Manuscript profile

  Market power specifies how firms in a market influence prices, and reveals the level of competition in the market. This paper investigated the impact of market power and macroeconomic variables effect on banking deposits in Iranian deposit money market using dynamic Bresnahan-Lau’s and Bayesian model averaging approach for the 18 bank in the Iran industrial banking sector. Annual data for the period of 2006- 2016 has been collected from annual financial statements of Iranian banks, Statistical Centre of Iran, Monetary and Banking Research Institute of Iran and central bank of Iran. By applying BMA approach the main macroeconomic variables have been determined from 8 variables. The results of model estimation indicated that market power for its 18 Iranian banks were 0.58 and the macroeconomic variables of liquidity money has negative and other explanatory variables such as fixed assets, growth of GDP, first order lag of deposits, deposits rate and cross effect of GGDP with deposits rate have positive posterior average on banking sector's deposits during the period of study.

  The main objective of this paper is the estimation of market power of the farmed rainbow trout in Iran. For this purpose we do the analysis of the statistical information relating to the marketing margin and the amount of the Rainbow trout Pool, the distribution on the market and also the transport and packaging costs Rainbow trout. The period of this paper is between 1986 to 2014. The way of investigating in this paper is the nonlinear least square. After confirming the normality and the absence of serial autocorrelation in the residuals, to resolve the problems of heteroskedasticity of regression was used to estimate appropriate weight. finally, after estimating model with appropriate weight and estimating marketing margin function, elasticity and expected changing at the retail level and in pools are calculated. The F and Durbin-Watson statistics and the coefficient of determination also represent the appropriateness of the estimated regression model. Results can be expressed as:The effect of transport costs and the production of trout (which will be available in the market) are negative and significant on the marketing margin. Rainbow trout production (in the pool) and a significant positive effect on marketing margin. As well as the effect of packaging on the cost of marketing margin is statistically valid. The amount of market power obtained for the trout ponds and the same product at retail are small although the amount of market power obtained for the trout ponds is far less than the strength in retail sales.  Manuscript profile
