Intergenerational equity

Topic: Government Budget, Fiscal Policy and FRBM · NCERT: Class 11, Ch 7 "Environment and Sustainable Development"; Class 12, Ch 5 "Government Budget and the Economy"

Meaning

Intergenerational equity means fairness between the people living today and the people who will live in the future. Each generation should pay for what it uses. It should not push the bill, such as public debt, or the damage, such as used-up natural resources, onto its children.

• Why it matters: when a government borrows today, it creates a tax bill that future taxpayers must pay. Intergenerational equity asks whether that is fair.
• It is an explicit objective of the FRBM Act 2003 (the Fiscal Responsibility and Budget Management Act). It is also the core idea of sustainable development (Class 11 NCERT): meeting today's needs without harming the ability of future generations to meet theirs.

Explanation

How borrowing today shifts the burden to tomorrow

• The chain from a bond to a future tax:
• The government sells bonds today, so it borrows.
• It repays them, say, 20 years later.
• That money comes from taxing the young people of that time.

• Their disposable income (income left after paying tax) falls, so they consume less.

• Less private capital for the future:

• Government borrowing uses up savings that private firms could have borrowed.
• Private capital formation (new factories, machines, roads) falls.

• So future generations inherit a smaller stock of capital and slower growth.

• Debt snowball (debt that grows by itself) makes the transfer bigger:

• old debt → interest must be paid → interest counts as spending, so the deficit rises → more borrowing → even more interest next year.

• Worked example: debt of ₹100 at 8% interest means ₹8 in interest. If the government borrows to pay it, debt becomes ₹108. Next year's interest is ₹8.64. The next generation inherits the growing pile.

• Stock vs flow: public debt is a stock, meaning the total amount owed at a point in time. The fiscal deficit is a flow, meaning the new borrowing in one year. Each year's deficit adds to what the next generation inherits.

When debt is NOT unfair to the future

• "We owe it to ourselves":
• Domestic debt is held by Indian citizens, banks and institutions.
• Repaying it moves money from Indian taxpayers to Indian bondholders.

• Resources shift between generations, but purchasing power stays inside the nation.

• Productive debt:

• Suppose the borrowed money builds roads, power plants or ports. If these earn a return above the interest rate, the future generation gets an asset along with the debt.

• Worked example: borrow ₹100 at 7%, so interest is ₹7 a year. The project adds enough GDP and tax revenue to yield 12%, or ₹12 a year. The debt pays for itself, and the future generation gains.

• NCERT's test: debt is a burden only if it reduces future growth.

• Ricardian equivalence (an idea from David Ricardo, revived by Robert Barro in 1974):
• Families are dynastic, meaning parents care about their children's welfare.
• So when the government cuts taxes by borrowing, parents save the whole tax cut to pay the future tax or to leave to their heirs.
• In this model, the burden on the next generation is cancelled inside the family.
• It fails when people are myopic (don't look ahead), face liquidity constraints (poor households must spend any extra money), or have finite horizons (no heirs, or no concern for them).

When the burden becomes real

• External debt:
• Interest and principal owed to foreigners must be paid in foreign currency.

• So real goods must be sent abroad as exports, and the nation as a whole becomes poorer.

• Borrowing to fund consumption, not investment:

• The present generation enjoys the spending.

• The future generation gets only the bill.

• When r > g (the interest rate is higher than GDP growth), the debt ratio snowballs. See the next sub-section.

Measuring it: the debt dynamics equation

Δd ≈ [(r − g) / (1 + g)] · d + primary deficit

• d = debt-to-GDP ratio
• r = nominal interest rate on debt
• g = nominal GDP growth
• primary deficit = fiscal deficit minus interest payments, as % of GDP
• Case 1: g > r (fair to the future). Take d = 56%, r = 7%, g = 10% and a primary deficit of 1%.
• (0.07 − 0.10)/1.10 × 56 = −1.53
• Δd ≈ −1.53 + 1.0 = −0.53

• The debt ratio falls to about 55.5%. Growth shrinks the relative burden on the future.

• Case 2: r > g (unfair to the future). Take r = 10% and g = 7%, with the same d and primary deficit.

• (0.03/1.07) × 56 = +1.57
• Δd ≈ 1.57 + 1.0 = +2.57

• The debt ratio snowballs, and each new generation inherits more.

• Domar condition (named after Evsey Domar): when g > r, the debt ratio can stay stable or fall even with a modest primary deficit.

In India

• The law:
• Intergenerational equity is an explicit objective of the FRBM Act 2003.

• The FRBM Review Committee (Chair: N.K. Singh, 2017) recommended making debt the anchor, meaning the main target that guides fiscal policy.

• 2018 FRBM amendment targets:

• General government debt (Centre + states, excluding debt they owe each other): 60% of GDP by 2024-25.
• Central government debt: 40% of GDP by 2024-25. [5]

• These targets were not met. The Centre's debt was still about 56% in 2025-26 RE (Revised Estimates). [2][5]

• The current anchor (Union Budget 2026-27):

• The debt-to-GDP ratio is the main fiscal anchor. The fiscal deficit is the operational target, meaning the number managed year to year. [2]
• Centre's debt: 55.6% of GDP (2026-27 BE, Budget Estimates), down from 56.1% (2025-26 RE). [2]
• Target: 50 ± 1% of GDP by 2030-31, reached through a glide path (a planned year-by-year path). [2]
• Fiscal deficit: 4.3% of GDP (2026-27 BE), down from 4.4% (2025-26 RE). [2]

• The 16th Finance Commission projects combined Centre + states debt falling from 77.3% (2026-27) to 73.1% (2030-31). This figure should be checked against the latest data.

• The growth threshold:

• An RBI Occasional Paper (2014) estimated a threshold of 61% of GDP for general government debt. Above this level, more debt starts to lower growth.

• Actual debt was 66.0% in March 2013, above that threshold. [4]

• Is r < g holding?

• India has had r < g in most recent years.
• The IMF (2025 Article IV) expects this favourable gap to continue. [6]

• But the RBI notes that the gap has "gradually narrowed down". It found only two years of primary surplus, 2006-07 and 2007-08, in its study period. [4]

• External debt (end-March 2026):

• US$ 762.8 billion, or 20.8% of GDP, up from 19.8% at end-March 2025. [3]
• Only 22.0% (US$ 167.5 billion) is owed by the government. [3]

• Forex reserves cover 90.6% of it. [3]

• A warning from history, the 1991 crisis:

• In the 1980s, even foreign borrowing was used for consumption.
• By 1991, forex reserves covered only about two weeks of imports.
• India took a US$ 7 billion loan from the IMF and World Bank, which led to the New Economic Policy.

• One generation's spending became the next generation's crisis.

• Environment angle: the same principle applies to natural resources. Over-using groundwater, forests or minerals today leaves less for future generations. This is the sustainable development idea in Class 11 NCERT.

Don't confuse with

• Intra-generational equity: fairness within the same generation, for example between rich and poor today. Intergenerational equity is fairness across generations.
• Debt sustainability: whether the government can pay all its debt without default and without impossible tax hikes or spending cuts. It is a question of ability. Intergenerational equity is a question of fairness. A debt can be repayable and still load an unfair burden on the future.
• Ricardian equivalence: a theory that says the burden on future generations is cancelled because parents save for their heirs. Intergenerational equity is the fairness goal, and Ricardian equivalence is one argument about whether debt really threatens it.
• Crowding out: one channel through which the burden passes. Government borrowing raises interest rates, and private investment falls. It is a cause of intergenerational unfairness, not the concept itself.

Prelims Hooks

• Intergenerational equity is an explicit objective of the FRBM Act 2003. It is also the core idea of sustainable development.
• Domar condition: when g > r, the debt-to-GDP ratio can fall even with a small primary deficit. Formula: Δd ≈ [(r − g)/(1 + g)]·d + primary deficit.
• FRBM 2018 amendment (N.K. Singh Committee, 2017): general government debt at 60% and Centre's debt at 40% of GDP by 2024-25. These targets were missed. [5]
• Budget 2026-27: Centre's debt is 55.6% of GDP (BE), with a target of 50 ± 1% by 2030-31. Debt is the anchor and the fiscal deficit is the operational target. [2]
• Trap: "Public debt is always a burden on future generations" is wrong. Domestic debt mostly moves money within the nation. Productive debt that earns more than the interest rate pays for itself. External debt, and debt that reduces growth, are the real burdens.
• Trap: "Ricardian equivalence says deficits pass the burden to the future" is wrong. It says forward-looking, dynastic households save the whole tax cut, so national saving does not change.

Mains Points

• Quality of borrowing decides fairness:
• Borrowing for capital spending (roads, ports, power) that earns more than the interest rate leaves future generations an asset.
• Borrowing for consumption leaves them only the bill, as the 1991 crisis showed.

• Use this to defend a high share of capital expenditure within a shrinking fiscal deficit, while the Centre's debt moves from 56.1% (2025-26 RE) to the 50 ± 1% target by 2030-31. [2]

• Fairness rests on r < g:

• The glide path assumes growth stays above borrowing costs. [2][6]
• The gap has narrowed, and India had only two primary-surplus years in the RBI study period. [4]
• A global interest-rate shock or a growth slowdown would push the burden onto future taxpayers.

• Remedy: build primary surpluses and deepen the bond market.

• Fiscal rules as a promise to the future:

• The missed 2018 FRBM targets for 2024-25 show that rules need credible anchors and clear escape clauses. [5]
• Link to twin deficits (a fiscal deficit and a current account deficit at the same time). External debt of 20.8% of GDP (end-March 2026) is paid in foreign currency, so it is a direct burden on future output. [3]
• GS-III answers can connect fiscal and environmental equity. Both ask the present generation not to use up the future's resources.
