Mains Previous Year Questions

Q.Explain the difference between computing methodology of India’s Gross Domestic Product (GDP) before the year 2015 and after the year 2015. (UPSC 2021)

 

Introduction Gross Domestic Product (GDP) is the most widely used indicator of economic growth. Over time, India has revised its methodology to align with global standards and to better reflect structural changes in the economy. A major revision was undertaken in 2015.
Body A) Before 2015:

  • GDP was measured at factor cost, i.e., income earned by factors of production (wages, rent, interest, profit).
  • Base year: 2004–05.
  • Industry estimates relied on Index of Industrial Production (IIP) and Annual Survey of Industries.
  • Services sector was measured largely through input-based indicators rather than actual value addition.

B) After 2015:

  • Shifted to GDP at market prices in line with the UN System of National Accounts (SNA 2008).
  • Base year: 2011–12.
  • Incorporated MCA-21 corporate database, financial sector indicators, and improved coverage of services.
  • Captures value addition more accurately, particularly in corporate and service sectors, and makes GDP internationally comparable.
Conclusion The 2015 revision marked a paradigm shift from GDP at factor cost to GDP at market prices, with better data sources and methodology. This has made India’s growth estimates more comprehensive, realistic, and globally standardized, though it has also sparked debates due to higher growth figures compared to the earlier series.

 


 

Q. Define potential GDP and explain its determinants. What are the factors that have been inhibiting India from realizing its potential GDP?

 

Introduction Potential GDP (also called potential output) is the maximum level of economic output that an economy can sustain over the long term without creating inflationary pressures. It represents the level of production when all resources—labour, capital, and technology—are fully and efficiently utilized. Actual GDP often falls short of potential GDP due to structural and cyclical constraints.
Body A. Determinants of Potential GDP:

  1. Labour Force: Size, skill, and productivity of the workforce.
  2. Capital Stock: Availability of physical capital like infrastructure, machinery, and technology.
  3. Technology and Innovation: Research, digitalization, and productivity-enhancing advancements.
  4. Institutional Factors: Efficiency of markets, regulatory environment, governance quality.
  5. Natural Resources: Land, water, minerals, and energy availability.

B. Factors inhibiting India from realizing potential GDP:

  • Low Labour Productivity: Despite a large workforce, issues of skill mismatch, informal employment, and low female participation restrict output.
  • Investment Constraints: Banking sector stress, low private investment, and infrastructure bottlenecks.
  • Technological Gaps: Limited R&D spending and slow diffusion of advanced technology.
  • Institutional Challenges: Regulatory hurdles, red tape, and delays in project execution.
  • Social and Human Capital Deficits: Poor health outcomes, underfunded education system, and inequality reduce effective human capital.
  • Agricultural Inefficiency: Low mechanization, fragmented landholdings, and climate vulnerabilities.
Conclusion India’s potential GDP is high due to its demographic dividend and vast resource base. However, structural bottlenecks in labour, capital, technology, and governance have created an output gap. Addressing these through skill development, infrastructure push, financial reforms, and innovation-led growth is essential for India to realize its full productive potential and sustain high long-term growth.
