Human capital refers to the stock of knowledge, skills, health, and abilities embodied in the people of a country that enable them to produce goods and services. Human capital formation is the process of increasing the knowledge, skills, and capacities of the people of a country. It is the accumulation of investment in education, health, on-the-job training, and migration that raises the productive capacity of human beings.
The concept of human capital was popularised by economists such as Theodore Schultz and Gary Becker. Just as investment in physical capital such as machinery and buildings raises the productive capacity of the economy, investment in human capital raises the productivity of labour and hence the capacity of the economy to grow. Education, health, and training are therefore considered forms of investment rather than mere consumption.
Human capital is different from physical capital in several ways. Human capital is embodied in human beings and cannot be separated from them, it is not subject to depreciation in the same way as machinery, and its returns accrue over a long period. The development of human capital is essential for economic growth, technological progress, and the improvement of the quality of life.
The major sources of human capital formation are:
$$\text{Human Capital} = f(\text{Education, Health, Training, Migration, Information})$$
Education is the most important source of human capital formation. It raises the productivity of workers, improves their earning capacity, and enables the economy to absorb and develop new technology. Education also generates positive externalities: an educated population is healthier, more law-abiding, and better able to participate in democratic life. The government plays a major role in education because of these externalities and because of market failures in the provision of education.
In India, education expenditure is shared between the central and state governments, with states bearing the major share. Expenditure on education includes expenditure on elementary, secondary, and higher education, and technical education. The Right to Education Act (2009) made free and compulsory elementary education a fundamental right of children in the age group of 6 to 14 years.
Health is a crucial determinant of human capital. A healthy worker is more productive, and investment in health care, nutrition, and sanitation raises the efficiency and life expectancy of the workforce. Health expenditure is treated as an investment in human capital because it prevents loss of working days, reduces the cost of treatment, and raises the capacity for work. The government provides health services through public hospitals and health centres, and recent initiatives such as Ayushman Bharat aim at universal health coverage.
$$\text{Human capital formation through health} = \text{Improved productivity} + \text{Reduced loss of working days} + \text{Higher life expectancy}$$
Despite progress, the Indian education sector faces several problems. The Gross Enrolment Ratio, particularly in higher education, is low. There are wide disparities in education across regions, gender, and social groups. The quality of education, especially in government schools, is a major concern, and there is a high dropout rate at the school level. There is also a mismatch between the skills imparted by the education system and the requirements of the labour market.
The problems of the health sector include the inadequate coverage of health services, particularly in rural areas, the high out-of-pocket expenditure on health, the shortage of trained medical personnel, and the prevalence of communicable and non-communicable diseases.
Human capital and physical capital are complementary in production. Physical capital such as machinery requires skilled labour to operate it, while skilled labour requires tools and equipment to work with. In developing countries, the shortage of human capital often limits the effective use of physical capital. The process of economic development therefore requires balanced investment in both physical and human capital.
| Basis | Physical Capital | Human Capital |
|---|---|---|
| Embodiment | Separate from the owner | Embodied in human beings |
| Depreciation | Wears out with use | Improves with use and learning |
| Transferability | Can be sold | Cannot be separated from owner |
| Returns | Direct monetary returns | Direct and external returns |
Human capital formation contributes to economic growth by raising the productivity of labour, promoting technological innovation, attracting foreign investment, and improving the quality of life. Countries with a high stock of human capital, such as those with high literacy and education levels, tend to grow faster. In India, the demographic dividend refers to the potential benefit of a young and growing workforce, which can be realised only if the population is educated, skilled, and healthy.
| Source | Contribution |
|---|---|
| Education | Raises skills and productivity |
| Health | Raises working capacity and life expectancy |
| On-the-job training | Raises specific skills |
| Migration | Moves labour to more productive uses |
| Information | Improves job and technology choices |
| Basis | Physical Capital | Human Capital |
|---|---|---|
| Embodiment | Exists separately | Embodied in humans |
| Depreciation | Depreciates with use | Appreciates with use |
| Mobility | Can be bought and sold | Cannot be separated |
| Returns | Monetary | Monetary and external |
Human capital formation is one of the most important determinants of economic growth and development. Investment in education, health, on-the-job training, migration, and information raises the productive capacity of the people and hence of the economy. In India, the expansion of the education system and health services has improved literacy, enrolment, and life expectancy, but problems of quality, coverage, and regional disparities remain. Realising the demographic dividend depends on converting a young population into a skilled, healthy, and educated workforce. Human capital, being embodied in people and improving with use, offers the most sustainable route to higher productivity, innovation, and an improved quality of life.
