چکیده:
The relationship between human capital and labor productivity is always important for economists. Considering the relationship between these two will also be remarkable in microeconomic studies. Meanwhile, the impact of different dimensions of human capital on labor productivity can be a measure of actual effect of human capital on productivity. The aim of this paper is to examine the effects of various dimensions of human capital (education, health, and experience), on labor productivity based on individual characteristics in Iranian economy. We use micro data (Cost–Income Survey of Urban Areas - 2013) and estimation of Quantile Regression (QR) econometric technique. For this purpose, net income (wage and salary) for employment in private sector is used as proxy of labor productivity. Our results show that in different quantiles, all three dimensions of human capital have a positive and significant effect on productivity of labor force employed in Iranian private sector. Meanwhile, in different quantiles, health indicators of human capital are more volatile than other dimensions of human capital, i.e. education and experience. So, in lower quantiles (Ql), the response of labor productivity to health indicators is more than higher quantiles (Qh). Because of that, any kind of health shock may have a greater effect on labor productivity in lower-income groups. This result shows the importance of health capital in social security, insurance and health systems and reminds us to improve the productivity of working people by means of better health capital.
خلاصه ماشینی:
Accordingly, in the employee productivity model, an attempt was made to test all three aspects of human capital, namely education capital, health capital, and work experience in the private sector, based on micro data from the results of surveys on the expenditure and income of urban households from the Statistical Center of Iran and using quantile regressions (QR).
In this regard, it is considered an innovation compared to other previous studies and will be newer, and efforts have been made to empirically follow the answers to the questions raised at the beginning of the article, such that individual characteristics including the number of years of education of the employed labor force (human capital derived from education), per capita consumption of vegetables, fruits, and cigarettes as physical and bodily health of the employed individual, marital status as social health of the individual in the household (human capital derived from health), and years of work experience of the private sector wage and salary employee (human capital derived from skill) have a significant impact on the level of labor productivity (although this situation is less observed for per capita cigarette consumption), and these results are consistent with the results of previous studies and answer the main questions of the article.
