Human capital refers to the skills, knowledge, and experience that individuals possess, which can contribute to their productivity and economic value. It includes education, training, and personal attributes that enhance a person's ability to perform tasks and solve problems. For example, a doctor with extensive training has high human capital, as their expertise allows them to provide essential healthcare services. Investing in human capital is crucial for both individuals and organizations. When people pursue further education or training, they increase their potential for better job opportunities and higher earnings. Similarly, companies that invest in their employees' development, such as through workshops or mentorship programs, can boost overall productivity and innovation.
