Economist Theodore Schultz invented the term human capital in the 1960s to reflect the value of our human capabilities. He believed that human capital was like any other type of capital; He believed that investing in human capital would lead us to higher production, (Investopedia)Investopedia defines human capital as a measure of the economic value of an employee's skills. The concept of human capital recognizes that not all work is created equal and that the quality of employees can be improved by investing in them. An employee's education, experience and skills have economic value to employers and the economy as a whole. (Investopedia) Investors define Human Capital as "the set of skills that an employee acquires on the job, through training and experience, and that increase that employee's value in the market." (Investors' words) Human capital is a way of defining and classifying people's skills and abilities as used in employment and otherwise contributing to the economy. (wikipedia) These are the definitions given by the online dictionary and the words of online investors, but in this article I will explain human capital and productivity based on Wheelan's concepts and other sources. I use examples from real people for better understanding. Human beings possess qualities, skills and talents that make them different from other human beings. Skills are considered human capital because they make you unique; they differentiate you and make you better at something than everyone else. There are different types of skills. Some humans possess poor skills, or human capital, such as a great education and knowledge in computer programming like Bill Gates, or the ability to be the best at basketball or golf, like Michael Jordan or Tiger Woods. These people have enormous human capital because they possess skills that no one else possesses, and these scarce skills give them the opportunity and advantage to become rich. They get paid a lot of money because no one else can do what they do at their high level. People invest in human capital, such as education and training, but some human capital cannot be invested in by anyone. Some human capital is like a gift, like a talent, and cannot be bought or paid for. The gift that Michael Jordan was born with was the physical and mental skills needed to be the best basketball player, and he never invested in them, he just worked on them to become better.
