Abstract
The Iranian electricity market is undergoing the first decade of restructuring. Effective competition in wholesale electricity market is a necessary feature of successful electricity industry restructuring. The paper examines the degree of competition in the Iranian electricity market during March to September 2009. The competitive benchmark analysis has been used to simulate producer’s behavior as a price taker firms and compare the competitive market results with actual market outcomes. The competitive benchmark has been calculated through generation costs of producers. Moreover, the possibility of execution market power has been considered by structural index. The finding indicates that the Iranian electricity market has a considerable potential to exercise power market and there were significant departure from competitive behavior during 2009.

Abstract
This article measures the market power in the loan and deposit markets in banking industry of Iran, including 10 state-owned and 4 private banks, during 1380-1389 (2001-2010) based on the evaluating of Lerner indices. To achieving this objective, a stochastic frontier cost function has been applied then market power was calculated. The main results of paper show over the observed period although market power in loan market has reduced, in deposit market it has increased. Outcome of calculations indicates some fluctuations in Lerner indices especially during (2005-10). So, it shows importance of economic policy aimed at removing the barriers of entry to market and regulation of them in order to make these markets more competitive.

Abstract
This paper based on the new empirical industrial organization model (NEIO) examines the impact of market concentration and cost efficiency on bank's profit rate margin in Iran. The study uses the model developed by Azzam (1997) to evaluate the market power and cost efficiency for 15 active banks in the banking industry. The empirical findings indicate a decrease in the market power of banks during the period 2001-2011. It is also shown that the conjectural variations index associated with the loans is -0.96, while demand for the loans is completely inelastic where its value is near to 0.087. Additionally, The market power and cost efficiency in the banking industry have been estimated 0.37 and -0.30 respectively meaning a decrease about 0.3 percent for the bank's profit rate due to the efficiency of cost and an increase about 0.07 percent due to the concentration.

Abstract
The electricity industry that has been administrated with integrated vertical structure worldwide is now undergoing dramatic changes. Electricity industry is converting to a competitive industry in which market powers determine the price of electricity, there for it is important to identify market power. The Electricity Market of Iran and Iran Grid Management Company were established in 2003 and 2004, respectively. One of the most important objectives of the restructuring of Iran’s Electricity Market is to establish a competitive environment. The purpose of this study was to assess the level of competition among regional power companies in the electricity market in 2013. The method employed separates the strategic companies from marginal companies by market share index in the hours of peak consumption in summer, and then simulates the performance of the strategic companies using Cournot’s model. Each Cournot (strategic) company aims to maximize its profits, assuming its competitors keep a constant production. This goes on to reach equilibrium, as long as companies do not take advantage of changes in their production. The results of the simulation shows that firms with higher market share at the summer peak hours have been acting strategically in 2013. Another part of the study investigated the circumstances of the power plants of these companies. Lerner’s index was estimated and showed that all the power plants of Tehran’s Regional Electricity Company had an index of higher than 50 percent which is an indicator of their high market power.
