Abstract
Human Capital is considered an investment, but of a special and qualitative kind. We emphasize that there are levels of defining the concept: investments in health, education, training and specializing, and the upper level, the stock of skills, talent, knowledge, embodied in the human personality as a participant to the economic, social, cultural, activities; micro and macro approaches. In this period, we can speak about a global overview regarding the two or more levels of human capital. This is mostly pointed when discussing the educational and the health capital and, on the other hand, the biological capital. We have to understand the concept in the inter-relation between the two levels and with the business and natural environments. Important is the causal chain in the construction of Human Capital: investments in health care and education → the impulse to ensure the formation and the modeling of the capabilities, skills and other specific biological stocks → the effective action of labour power, creating new values added → economic development within a structure (in our case, EU).
