| This study examines the deviation of concentration from its steady state level in Iranian manufacturing industries. The study is carried out for 94 industries based on cross- section method with four-digit ISIC code in the years 1999 and 2007. The coefficient of partial adjustment is significant and less than one. Therefore there is significant partial adjustment towards steady state level of concentration. The same results were obtained in subsamples including 47 industries with high advertising intensity and 47 industries with low advertising intensity. The comparison of Herfindahl Hirschman index indicates that the level of industrial concentration in the majority of industries (63 percent) has decreased during this period. The findings of the study support the Sutton the market size in exogenous sunk cost industries. But the result is not valid for endogenous sunk cost industries. |
