How to think it through
Potential GDP is the output an economy can produce at full use of its resources without raising inflation. Determinants: labour, capital, productivity. India's constraints: low female participation, poor skills, weak investment, infrastructure gaps, regulatory and land issues.
Model answer
Potential GDP is the highest output an economy can sustain when its labour and capital are fully used, without pushing up inflation. When actual GDP falls below it, the shortfall is the output gap. The RBI has placed India's potential growth at around 6.5–7%.
Determinants
- Labour: size of the workforce, participation and skills.
- Capital: machines, infrastructure and buildings.
- Total factor productivity: technology, management, innovation.
- Institutions: rule of law, contract enforcement, regulation.
- Natural resources and energy.
What holds India back
- Low female labour participation wastes much of the potential workforce.
- Weak skills and learning outcomes.
- Investment slowdown after 2012 from stressed balance sheets.
- Infrastructure gaps and high logistics costs.
- Land and labour market rigidities.
- Small firm size: most firms stay tiny, informal and unproductive, the 'missing middle'.
- Slow contract enforcement in courts.
- Covid scarring after 2020: lost schooling and closed small firms.
Conclusion
Raising potential growth means more workers, better-trained workers and more productive firms. Public capex, the Labour Codes and NEP 2020 aim at exactly these.
Draw: Two curves: a smooth upward line for potential GDP and a wavy line for actual GDP, with gaps shaded.
Keywords, cases and data to drop in
