Abstract

This paper using generalized Roeger's model calculated the LERNER index for Iranian active industries in 4-digit ISIC codes during the period 1995-2007. The findings indicate that the LERNER index has been between 8 to 16 percent in 38 industries among 131 ones. The index also in different industries shows that more than 50 percent of Iranian industries have monopolistic power such that they have generated a significant gap between price and MARGINAL COST. Comparing the LERNER index with Herfindahl-Hirschman and four - firm CONCENTRATION ratio indices gives this result that the industries with high CONCENTRATION ratio have greater value of LERNER index so that The four-firm CONCENTRATION ratio of 20 industries (among the 29 industries) has had a value more than 40.
