The correct option is 2 and 3 only.
Explanation
Human capital refers to the stock of knowledge, skills, education, health, and training possessed by a population. In economic theory, human capital is treated as a critical engine of growth, distinct from physical capital, as it directly influences the efficiency and capability of the workforce.
Statement-wise Analysis:
- Statement 1 is Incorrect. Human capital is the primary source of new ideas and technological breakthroughs. A well-educated and skilled workforce drives research and development (R&D), thereby fostering innovations and inventions rather than hindering them.
- Statement 2 is Correct. The availability of educated and skilled labour facilitates the diffusion and adaptation of new technologies. A knowledgeable workforce has the absorptive capacity required to understand and implement complex technologies effectively.
- Statement 3 is Correct. Investment in human capital-such as through education, on-the-job training, and healthcare-improves the physical and mental capacity of workers. This enhancement leads to higher efficiency and output per worker, thereby increasing labour productivity.
Key Takeaway:
Human capital promotes economic growth by stimulating innovation, enabling the absorption of new technologies, and significantly enhancing the productivity of the labour force.
