Subtopic: Environment & Ecology · Equity and sustainable development
Show model answer outline
Introduction → define intra- and inter-generational equity and their place in sustainable development → explain intra-generational issues (present distribution) → explain inter-generational issues (future stewardship) → link to inclusive growth → Conclusion on balancing both.
Key points- Sustainable development (Brundtland) rests on inter- and intra-generational equity.
- Intra-generational equity = fair resource/income/opportunity distribution within today's generation.
- Intra issues: poverty, unequal access, environmental burden on poor (environmental justice).
- Inter-generational equity = future generations' right to healthy environment and natural capital.
- Inter issues: groundwater over-extraction, fossil-fuel depletion, biodiversity loss, GHGs.
- Climate justice and CBDR embody intra-generational fairness between nations.
- Precautionary principle and conservation safeguard inter-generational interests.

Subtopic: Indian Economy · Capital formation and PPP concession agreements
Show model answer outline
Introduction → define investment as capital formation → explain gross/net and fixed capital formation and its growth role → shift to concession agreements in PPP → discuss factors in designing them (risk allocation, tenure, tariff, termination, dispute resolution) → Conclusion on balancing viability and public interest.
Key points- Investment in economics = capital formation, not purchase of financial assets.
- Capital formation adds to the stock of physical/productive capital over time.
- Gross Fixed Capital Formation (GFCF) is a key growth and productivity driver.
- Net investment = gross minus depreciation, reflecting genuine capacity expansion.
- PPP concession agreements mobilise private capital amid fiscal constraints.

Subtopic: Indian Economy · GST compensation and fiscal federalism
Show model answer outline
Introduction → GST as destination-based tax and the compensation guarantee → rationale of the Compensation to States Act 2017 → COVID-19's impact on the cess fund and shortfall → resulting federal tensions and resolution → Conclusion on cooperative federalism.
Key points- GST is a destination-based tax; states surrendered key indirect-tax autonomy.
- Compensation to States Act 2017 guaranteed compensation for revenue loss.
- States assured 14% annual growth on 2015-16 base revenue for five years (to June 2022).
- Shortfall funded by Compensation Cess on demerit/luxury goods (tobacco, autos, aerated drinks).
- COVID-19 depressed consumption, so cess collections fell far short of dues.
- Centre's 'act of God' framing and split of shortfall angered states.
- Opposition states saw erosion of the guarantee and of fiscal federalism.
- Resolved via back-to-back borrowing and extension of cess to repay loans.

Subtopic: Indian Economy · Government budgeting and public finance
Show model answer outline
Introduction → basis of distinction → Revenue Budget and its components → Capital Budget and its components → significance → Conclusion
Key points- Distinction rests on whether transactions affect government assets/liabilities: revenue account (no change) vs capital account (change).
- Revenue receipts = tax revenue (income, corporate, GST, customs) + non-tax revenue (interest, dividends, fees).
- Revenue expenditure is recurring: salaries, pensions, interest, subsidies; creates no asset.
- Capital receipts create liabilities or reduce assets: borrowings, external loans, disinvestment.
- Capital expenditure creates assets or repays loans: infrastructure, machinery, debt repayment.
- Revenue deficit = revenue expenditure minus revenue receipts.
- Capex is growth-enhancing; high revenue deficit signals borrowing for consumption.
