Tax avoidance reduces the outflow of cash from the company to the government, which from the past to the present is considered a value for shareholders. Therefore, considering such a necessity, the present study, in order to help tax administrators, examines the effects of investment inefficiency in the labor force on corporate tax avoidance activities for a sample of 64 export companies in Iran during the period of 2009 to 2019. For this purpose, in two stages, Dynamic Panel Data method and Generalized Method of Moment (GMM) estimator were used; in this way, first, the inefficiency of investment in labor was estimated and then its effect on corporate tax avoidance was estimated. The results of estimating the research model indicate the direct effect of investment inefficiency in the workforce on corporate tax avoidance. In addition, the results showed that the market value and size of the company are associated with a direct and inverse effect on tax avoidance, respectively. Thus, increasing ambiguity, a weaker control environment, and a reduction in expected cash flows due to inefficient investment in the workforce provide opportunities for the company's manager to increase tax avoidance, and tax policymakers need to pay special attention to this issue.

This article explores how different factors influence the number and dynamics of firms in supplier-dominated industries. These industries are typically traditional, small, and depend on external suppliers for innovation. The article uses a hybrid simulation of system dynamics and agent-based modeling to capture the realistic assumptions that firms do not have complete market information and make decisions based on simple heuristics and past and current conditions. The article conducts experiments to examine how initial conditions, machine life, economic parameters, producer optimism, production growth rate, and demand elasticity affect the entry and exit patterns and the number of firms in the industry. The article uses variables such as the time to reach the peak number of firms, the number of firms at the peak, and the number of firms at the end of the simulation period to represent the shape of the industry distribution. The experiments show that the initial number of firms, demand elasticity, machine life, and financial resources have the most significant effects on the distribution shape, while other factors such as economic growth also have some nonlinear effects.

The purpose of this article is to evaluate the effect of industrial concentration and import of capital goods on the intensity of energy consumption in Iranian industries. Industrial concentration index has been calculated using Herfindahl-Hirschman method and relative entropy. In this research, the panel data method and the fixed effects model were used to estimate the coefficients of the models. The research findings indicate that between 2002 and 2018, industrial concentration and import of capital goods have a positive and statistically significant effect on the intensity of energy consumption. So that, one percent increase in the share of the industry in the market, increases the intensity of energy consumption between 0,089 to 0.203 percent. Also, the price of energy carriers has a negative effect on the intensity of energy consumption. Considering the inverse relationship between the price of energy carriers and energy intensity and the low elasticity of the price, it is necessary that incrementally raise the energy prices for industries logically causing environmental pollution to decrease their energy intensity. It is suggested that capital goods enter industries that have low energy consumption.

Abstract
The aim of this paper is introducing a new method to estimation monopoly power and uses it for 136 Iranian manufacturing industries at 4 digits ISIC level during 2005-2013. The method used is stochastic frontier approach. The results indicate that the markup of nearly 98 percent of manufacturing industries is between 10 and 40 percent and they have an uncompetitive behavior. The average industries markup in Iran had a rising trend over time, reducing their average returns to scale. According to the results; there are suggested canceling the exclusive advantages that used to grant to some industries, lowering the tariff for increasing foreign competition with implementation necessary standards in order to production, importing industerial outputs and expanding industerial activities in the form of cooperatives.
