Comparative analysis of some approaches to the modeling of the impact of human capital on the added value in the economy

The need to use the modeling method to study the influence of human capital on the formation of value added is due to the fact that, as a result of the formation of the information economy, the areas of practical application of the theory of human capital are expanding substantially.The purpose of the article is a comparative analysis of some approaches to modeling the impact of human capital on value added in the economy.The conclusion is drawn about the existence of mutual influence of the technical and technological level of production and development of human capital due to the free distribution (diffusion) of knowledge between workers and enterprises. The use of obsolete technologies in production, the increase in equipment wear due to a decrease in the volume of fixed capital investment, in contrast, lead to significant losses of the human capital of enterprises. The discrepancy between the available and necessary skills, abilities and competence of personnel to work with new equipment and software is a factor that hinders the growth of value added, as this reduces the level of susceptibility of enterprises to the penetration of innovations.It is proposed to use economic growth models based on the neo-classical Solow growth model, such as the Arrow-Romer model, the Lucas model, the Mankiw-Romer-Weil model for modeling the impact of human capital on value added in the economy.The use of the Arrow-Romer model is possible due to a formalized relationship between the levels of personnel accumulated in the process of knowledge work and labor equipping. To analyze the impact of the accumulation of human capital on value added in the economy allows the model of Lucas, based on an assessment of external and internal effects of human capital on the production of final products. The Mankiw-Romer-Weil model allows you to forecast the necessary level of investment in human capital with the given resource productivity and the level of added value of products.Prospects for research in this direction are the further empirical studies of the influence of human capital on the formation of value added in the Ukrainian economy, taking into account the tendencies towards deindustrialization of the country's economy.
