The question that is considered by researchers in the field of knowledge-based economy is that among the factors affecting intangible investment, does information and communication technology have a heavier weight than the rest of the factors? In this study, using the Corrado,Hulten and Sichel (CHS) approach, the measurement of intangible investment is calculated. In their research, intangible investment has been divided into three major parts: computer information, innovative assets, and economic competencies. Then these three components are divided into nine parts. In this article, we select the component of information and communication technology, which is the first component of intangible transitory capital, and its effect on Total Factor Productivity(TFP) has been investigated. The field of study is manufacturing industries with a four-digit economic activity classification code for employees of ten and above during the years 1996 to 2018. Using panel data and GMM, the productivity function was estimated for manufacturing industries. The results of this research show that ICT has a significant role on the productivity of all production factors, and its coefficient is higher than other intangible investment components.

In this study, by employing a flexible cost function we calculate the technological change measure and total factor productivity and examine the impact of technology on the combination of input and scale of production in Iranian manufacturing industries. According to the results of technological change at the average data level, total production cost of industry has decreased by an amount of 0.49 percent during the period 1996-2009. All 23 studied industries have deviation from input technology. In addition, technological change has led to saving in raw materials and to an increase in the use of three inputs of labor, capital, and energy. The technological change is non-neutral and has led to changes in production scale and based on the technology scale bias, technological change has led to a decrease in optimal production scale.

In this study, the factors affecting total factor productivity (TFP) are estimated with an emphasis on foreign direct investment (FDI) in Iran and 23 selected countries using the data over the period 1996-2006. TFP is computed using the Divisia index technique. The findings of this study show that the main determinants of TFP comprise FDI capital stock, R&D capital stock, university enrolment gross rate (as a proxy for human capital), the degree of openness (as the main sources of technological progress) and the ratio of actual output to potential output (as a measure of capacity utilization rate).. However, the magnitudes of the estimated parameters confirm that capacity utilization rate has the highest effect while FDI capital stock has the lowest effect on TFP.

Productivity improvement is one of the important factors in economic growth.. This paper attempts to study the impact of human capital on Total Factor Productivity in the industrial sector of East Azarbaijan Province in Iran during the period 1374-1385 (1994-2005). To probe the impact of human capital on Total Factor Productivity, the Data Envelopment Analysis (DEA) technique the Malmquist Index have been applied. The results indicate that the management efficiency, as an index of human capital, affects the TFP to almost the same extent as other factors.

In this study, we examine factors influencing the Total Factor Productivity (TFP) in the Iranian economy. These factors are the percentage of higher education employees as proxy for human capital, the government research and development capital stock and the ratio of actual output to potential output as the index of capacity utilization. We estimate TFP using the ARDL (Auto-Regressive Distributed Lag) method covering data over the period 1968-2004. The results indicate that in the long run, the percentage of higher education employees, the government research and development capital stock and the capacity utilization have had positive and significant effects on productivity. In this period, in spite of increasing trend in human capital and the government R&D capital stock, TFP accounts for only five percent of the long run economic growth. The reasons for this meager share of TFP growth is reduced the degree of competitiveness, misallocation and inefficient use of resources in the economy.

Freedom of choice and competition are viewed as vital factors for economic growth. In this paper, we use a growth model to examine the impact of economic freedom on the economic growth across the world countries for the period 1999-2004. Our study differs from the previous studies in terms of the modeling, the scope of the study, and the selected sample. The results, however, are consistent with those of the previous studies. Given the fact that Iran’s position in the world is low in terms of economic freedom, that economic freedom has a significant role in economic growth, it is necessary for investors and firms to have suitable conditions for transparent and accurate decision-making. Creation of the favorable economic conditions is the responsibility of the government and thus, it is necessary to have defined policies and planning for the establishment of conditions for economic freedom in the society. Creation of social condition for economic freedom of economic agents is a convenient orientation that is favorable with economic growth policies and must be internalized in the Iran's economic policies.

Labor force and its quality (human capital) have made large contribution to economic growth and development in many countries. Health is also considered as a way to improve both labor quality and productivity. Present research aims to investigate and analyze the effect of health on labor productivity for the period 1976-2004.
The ARDL econometric model used in this study incorporates variables such as life expectancy as a proxy for health, per capita physical capital, and the actual to potential output ratio as the most influential factors on labor productivity.
The results indicate that about 38.2% of labor productivity growth is contributed by an increase in health. In addition, our result show that in fourth plan (2005-2009), labor productivity growth will be about 2% less than the figure envisaged in the plan.

Since the advent of early business cycles theories based on self-sustaining behaviors, many theories and models have been suggested to explain causes of cyclical fluctuations. Although in the 1960s, with the acceptance of Keynesian ideas there was a less interest to identifying the sources of disturbances, today the debate over the sources and propagation of economic fluctuations still rages among macroeconomists.
This paper uses a multisectoral business cycles model for identifyingication the role and importance of aggregate and sectoral shocks in business cycles of the Iranian manufacturing sectors. Aggregate shocks involve innovations in oil revenues, money supply, government expenditures, and real exchange rate, and productivity shocks are connsidered as sectoral shocks. Our results indicate that all types of shocks are important, but aggregate shocks are the dominant source of sectoral output fluctuations. Variance decomposition of the manufacturing output growth indicates that 85.4 percent of aggregate output disturbances can be explained by aggregate shocks. Therefore, macroeconomic policies inconsistent with industrial development requirements could disturb endogenous growth of the Iranian manufacturing sectors via weak total factor productivity. At the presence of the exogenous impulses, while aggregate shocks are significant sources of output fluctuations, it seems disturbances are threatening the long run economic and industrial growth, even in the oil boom periods.
