Abstract
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.

Abstract
Despite the fact that productivity has long been studied in economic literature, only in recent years it has been considered as the important issue in the Iranian economy and the Fourth Development Plan could be considered as a turning point on looking at it. Based on the Plan, one third of economic growth should come from the productivity improvement so it is expected to see the results of productivity growth on the performance of economy and the firms. This study aims to examine the impacts of total factor productivity and labor productivity on the survival of new firms in Iranian manufacturing industries. Data of this study comes from the censuses taken by the Statistical Center of Iran in 2000, 2001 and 2002. The firms were divided into two categories of survived and exited firms. Using the Cox hazard model, the impact of productivity on their survival probability has been examined. Contrary to expectation, the results of this paper indicate that total factor productivity does not show a significant positive impact on survival probability of these firms. However, increase in labor productivity significantly increases the survival of new firms. This finding means that labor productivity, which can be considered as a manifestation of human capital in each firm, is very important for the survival of firm, especially in the first year of entry.

Abstract
Various economic studies have shown that Minimum Efficient Scale (MES) varies in different industries and therefore economic firms enter in industries with different sizes. Nevertheless, firms attempt to reach the MES of the industry in a reasonable time to survive in an industry. From different point of view, the reasonable time can be evaluated with speed of adjustment. In fact, there is a significant relationship between the time and the speed of adjustment. Accordingly, this paper attempts to determine the speed of firm size adjustment in Iranian manufacturing industries at 4-digit ISIC code industry levels. Investigating the effect of various factors on the speed of adjustment is another goal of this paper. In this study, Comanor-Wilson method based on employment criteria is used for the estimation of MES. Using cross-sectional regression technique over three years, the coefficients of industry structure, technology levels and distance to MES at the time of entry is estimated on geometric mean of . The results of this study show that in contrast to the expectation, firms that are far away from MES, adjust themselves with slower speed. From policy point of view, the finding points to inability of Iranian manufacturing industries’ firms in achieving an appropriate speed of adjustment at the time of entry. Therefore, supportive policies are necessary for survival of new entrance firms during infancy.
