The Role of Human Capital on the Development and Progress of Various Sectors in Iran Economy

M. Ebrahimi and M. Noonejad    

Abstract: We investigated the factors affecting the whole of value added of Iranian economy as well as agricultural and industrial sectors. As, educated labor can affect value added more than uneducated labor, labor was divided to two groups and their effects on value added were investigated separately. Also, selected economical indices were compared pre and post Islamic revolution by using time series data from 1962-2002. Ordinary Least Squares, autoregressive distributed lag model, Johanson cointegrated vectors and vector error correction model were used to investigate the long and short run effects of variables on value added. Student Test (t) was used to compare selected indices pre and post the revolution. The results showed elasticities of economy value added with respect to investment, educated and uneducated labor force are 1.46, 0.059 and -2.32%, respectively. Elasticities of industrial value added with respect to the above-mentioned variables are 0.268, 0.895 and -1.3, respectively, while elasticities of agricultural value added with respect to investment, educated and uneducated labor force are 0.321, 0.369 and 6.94, respectively shows the most important factor in this sector of economy is uneducated labor force. Comparing the average growth rate of variables pre- and post-revolution indicated growth rates of economy value added, the economy investment, industrial and agricultural educated labor force and the economy uneducated labor force are different significantly. Other variables such as growth rate of value added of agricultural and industrial sectors and investment in these two sectors did not have significant differences.
