The aim of this paper is to provide a comparison between different methods of natural monopoly regulation for electricity distribution companies in Iran and introduce the best suitable one based on productivity, quality and incentive considerations. Here we have concluded that the price cap regulation model is the most efficient method of regulation for the situation under consideration. Based on the literature, the target values of both productivity and quality has been calculated in different scenarios of this research. The sample consists of 39 electricity distribution companies in Iran during period 2006 to 2016. First, using the SFA and DEA methods to determine the efficiency score of each company, we have calculated the X-factor for every firm in a 5-year period. In addition, the X-factor was calculated based on Malmquist index and differential method. The results suggest that target X-factor is in the range of 1.7% to 3%. The results indicated that there is an opportunity to increase productivity of electricity distribution companies. To encourage the firms to improve their productivity, a higher target rate of productivity growth would be considered for low-efficiency firms and a lower target for high-efficiency ones. Service quality has been evaluated mainly by quantification and measurement of energy not supplied (ENS) and the waiting time for a new customer to be connected to the power grid and to be able to use electricity. And the target quality value was set for each company.

One of the features of market structure is the extent of barriers to entry. According to economic theories, it is expected that when the barriers to entry increase, the degree of monopolistic power in industrial markets will consequently increase. Hence, in this paper we measure the intensity of barriers to entry and evaluate this structural variable in Iranian manufacturing sector. This study examines the factors that affect the extent of barriers to entry in industrial markets in the context of a dynamic panel data model with the technique of generalized method of moments (GMM). The findings show that the degree of concentration, intensity of advertising, research and development costs, rate of returns and economies of scale have significant and positive effect on the extent of barriers to entry in industrial markets of Iran.

Poverty is a worldwide phenomenon which both developed and developing countries are entangled with. Poverty alleviation is now considered as a goal by governments and international institutions. The emphasis is very much on poverty reduction by Iran’s Constitution and other binding Acts such as socio-economic plans and The Perspective Document. In this paper, an attempt has been made to measure different poverty indices with emphasis on nutrition approach. Head count ratio, poverty gap and Sen index are among the poverty indices measured in this study. Our findings indicate a reduction in absolute poverty along with an increase in relative poverty during the period of the study. It has also been shown that the extent of poverty depends on the concept of poverty accepted by authorities. Considering the facts relating to Iran’s economy as well as resource limitation, the best concept of poverty for policy formulation is the absolute one.
