In this paper a formal model of the productivity dynamics of manufacturing industries is developed with key features being the absence of optimal decisions and equilibrium coordination, heterogeneity of industries with respect to their innovative ability and cumulativeness of innovations together with the working of spillover effects. From that model the law of motion of the productivity distri...

the paper examines industrial concentration in iranian food products and beverages industries using firm level data aggregated to the 4-digit isic industry level between 2002 and 2004. based on different concentration indices the average level of concentration has increased slightly for the period of study. the empirical results show that increase in the level of concentration is more likely in...

This paper investigates the relative labor productivity level for total manufacturing in Germany, Sweden and the US for the period 1980–2001. The paper also presents estimates of labor productivity levels for 18 different manufacturing industries for the period 1993–2000. The results show that the Swedish manufacturing productivity caught up with German and US productivity in the 1990s, overtak...

it is now evident in the literature that the information and communication technology (ict) has a positive and significant impact on the productivity and economic growth. most studies in this area, however, are limited to the developed countries. given different regulations and economic conditions, and also an increasing trend in allocating resources to ict in developing countries, it is import...

This paper estimates a structural model of learning-by-doing. Treating production experience as a state variable, this paper provides estimates of the structural parameters obtained from the first order conditions arising from the plant’s maximization problem. Estimates are provided using data on 4-digit manufacturing industries and plant-level observations. Using aggregate industry data, the r...

A Hall type model that includes intermediate materials in the production function and allows for non-stochastic time variation in the contribution of technical change to output growth is used to estimate markup and returns to scale for eight Australian manufacturing industries at approximately the two-digit level, during the period 197172 to 1984-85. Six of the eight manufacturing industries in...

The sources of aggregate productivity growth are explored using detailed data for four-digit U.S. manufacturing industries during 1958-96 and a decomposition formula which allows to quantify the contribution of structural change. Labor productivity as well as total factor productivity are considered and the aggregation is performed with either value-added or employment shares. It is shown that ...

 Based on the recent literature of heterogeneous firms, productive firms self select themselves into foreign markets. In this framework, there is a productivity rise prior to exporting. On the other words, different export performance across firms is linked to their heterogeneity.   The main purpose of the present paper is to examine the so-called hypothesis of heterogeneous firm in Iran. For ...
