Human Resources and Economic Development: Roles, Impact, and Population Quality

• Dual Role of Human Resources

  Human resources play two critical roles in economic development:

  • (A) Factor Services: Contributing labour and entrepreneurship to economic activity.
  • (B) Units of Consumption: Affecting consumption patterns and savings.

• Human Resources as Factor Services

  As providers of labour and entrepreneurship, human resources contribute directly to production. More people imply more resources available for work and innovation. Population growth, therefore, can support economic growth under certain conditions:

  • i) Minimum Scales and Infrastructure Efficiency

    Some infrastructure becomes economically viable only above certain population densities. Examples include roads, dams, ports, and irrigation systems. Many industries also benefit from economies of scale, which are more achievable in larger populations due to greater division of labour and higher demand.

  • ii) Demographic Transition and Savings Rate

    In UDCs, a high child dependency ratio leads to low savings due to high consumption relative to income. However, during the demographic transition, the ratio of workers to dependents increases, leading to higher income, lower consumption, and increased saving activity.

  • iii) Capital Formation in Agriculture

    In agrarian economies, the family farm acts as saver, investor, and producer of capital. During off-seasons, families invest in infrastructure like fences, irrigation, barns, roads, etc. With more population, more labour is available to engage in this type of informal capital formation, enhancing the agricultural capital stock.

  • iv) Labour Force Participation and Dependency Ratios

    Rising population growth and dependency ratios impact labour force participation through changes in working hours, entry and retirement age, and increased employment of women outside the household.

  • v) Trade Specialisation under Labour Abundance

    According to the Heckscher-Ohlin model, a country with abundant labour will specialise in labour-intensive goods. As labour supply grows, the country can trade more, especially if already engaged in exporting such goods.

    Comparative average hourly labour costs:

    • Europe: $20
    • USA: $19
    • Japan: $18
    • Asia (avg.): ~$1.65

    Population growth can thus support trade expansion and productivity gains.

  • vi) Technological Change and Talent Pool Expansion

    With a larger population comes a larger pool of talent, which can accelerate the pace of technological advancement by providing more individuals capable of innovation, discovery, and scientific progress.

  In summary, human resources are indispensable for economic growth not just by their size, but through the quality of population. Skills, education, innovation, and technical know-how are the ultimate differentiators in their effectiveness as economic drivers.

Human Resources as Units of Consumption and Their Impact on Economic Development

• When viewed as units of consumption, human beings place demand on the national product. Their sheer number matters greatly—especially when the population size exceeds what the economy can sustain, leading to overpopulation and a range of related challenges:

  • Food Scarcity: A rising population increases demand for food stocks, often causing a gap between demand and domestic supply, leading to acute shortages.

  • Reduced Capital Formation: A large share of output is consumed in the present, leaving little surplus for investment. This slows capital accumulation and economic development.

  • Strain on Balance of Trade: Countries with food deficits may have to divert scarce foreign exchange from essential industrial imports toward food imports, leading to trade deficits and difficult policy choices.

  • Unemployment: Overpopulation leads to rising unemployment, with associated economic and social issues, especially in underdeveloped countries (UDCs).

  • Pressure on Social Overhead Capital: Increased population demands more spending on education, health, and infrastructure, diverting funds from physical capital formation.

• In summary, rapid population growth acts like a handicap — “extra weight carried by a race-horse”. It slows capital accumulation, reduces productivity growth, and adds more people to support than output produced. It creates barriers to raising living standards.

  Ultimately, whether a population is an asset or a liability depends on its quality. This quality is dynamic and can be enhanced through targeted investment in human capital development programmes, distinguishing it from mere physical capital formation.
