Competition and Market Power in the Manufacturing Industries: A Comparative Study

This paper examines the gap between marginal cost and the price of ۲۲ manufacturing industries in Iran at ISIC ۲-digit level and ۳۲ industries at a ۳-digit level during ۱۹۹۵-۲۰۱۵ compared to selected countries. It examines the gap by using the Hall-Roeger model. We found that in garments, basic chemicals, non-metallic mining, and refined petroleum products, the price and marginal cost difference are high and in tobacco industries are low. In ۳ out of ۲۲ industries at ISIC ۲- digit level and in ۱۱ out of ۳۲ industries at ۳-digit level, Iranian industries have higher markups and a significant gap between price and marginal cost than Japan, Germany, France, and the United Kingdom. Also from ۳۲ industries in ISIC ۳-digit level and ۲۲ industries in ۲-digit level, Iran has the lowest mark-up in the tobacco industry with ۱.۰۳ and in chemical products with ۲,۳۳, has the highest markup.
