Concept: The accelerator (J. M. Clark) measures the effect of a change in consumption (demand/output) on induced investment: β = ΔI/ΔC.

1. A rise in consumer demand requires more capital stock, so investment rises by a multiple of the change in consumption.
2. Option (C) – effect on investment of a change in consumption (Hindi: उपभोग के निवेश पर प्रभाव) – is this.
3. The multiplier works the other way: effect of investment on income (and consumption).

Short trick: Multiplier: ΔI → ΔY; Accelerator: ΔC → ΔI.

Concept: Classic central-bank functions: currency issue, banker to government (including public debt management), banker's bank and lender of last resort, credit control, custodian of foreign exchange reserves.

1. Note issue – RBI Act Sec. 22.
2. Public debt management – RBI manages Centre's and States' borrowing.
3. Forex reserves – RBI is custodian under FEMA.
4. Black money control is the task of tax and enforcement agencies (Income Tax, ED, etc.), not a central-bank function.

Short trick: Central bank = Currency, Credit, Government's banker, Banks' banker, Forex – not black money.

Concept: Stagflation = stagnation + inflation: rising prices together with high unemployment and slow growth.

1. Seen in the 1970s after oil-price (supply) shocks.
2. It contradicted the simple Phillips curve trade-off (high inflation with low unemployment).
3. Usually caused by adverse supply shocks shifting aggregate supply leftward.

Short trick: Stag (stagnation, high U) + flation (inflation).

Concept: In RBI's classification, M₀ = reserve money (high-powered money / monetary base).

1. M₀ = currency in circulation + bankers' deposits with RBI + other deposits with RBI.
2. M₁ = currency with public + demand deposits + other deposits with RBI (narrow money).
3. M₃ = M₁ + time deposits (broad money); M₂ adds savings deposits of post office/short-term time deposits.

Short trick: M0 = Reserve / high-powered money; M3 = broad money.

Concept: The World Bank Group has five institutions: IBRD (1944), IFC (1956), IDA (1960), ICSID (1966) and MIGA (1988).

1. IBRD + IDA together are called 'the World Bank'.
2. The IMF is a separate Bretton Woods twin institution dealing with balance of payments and exchange-rate stability, not part of the World Bank Group.

Short trick: World Bank Group = IBRD, IDA, IFC, MIGA, ICSID; IMF is its 'twin', not member.

Concept: Tax incidence falls more on the side that is less elastic. Share of buyer = e_s/(e_s + e_d).

1. Perfectly elastic demand: e_d = ∞ → buyer's share = 0.
2. Buyers will not pay any higher price, so the price stays the same and the seller bears the whole tax.
3. If demand were perfectly inelastic, the buyer would bear it all.

Short trick: Elastic side escapes, inelastic side pays.

Concept: Cutting income tax raises disposable income (Y − T), so consumption and aggregate demand rise (tax multiplier = −b/(1 − b)).

1. Cutting child allowances reduces transfers → lower demand.
2. Raising indirect taxes raises prices and cuts real spending.
3. Taxing travel abroad mainly affects imports/BoP, and is itself a tax increase.

Short trick: Expansionary fiscal policy = ↓ taxes or ↑ spending.

Concept: Hugh Dalton (Principles of Public Finance, 1922) gave the principle of maximum social advantage – the fundamental principle of public finance.

1. Public finance is best when MSB of public expenditure = MSS of taxation.
2. Pigou called a similar idea 'maximum aggregate welfare'; Musgrave also discussed it.
3. Adam Smith – canons of taxation; Modigliani – life-cycle hypothesis; Lewis – unlimited supplies of labour.

Short trick: Dalton: MSB (spending) = MSS (taxation) → maximum social advantage.

Concept: Revenue deficit = Revenue expenditure − Revenue receipts.

1. Fiscal deficit = Total expenditure − (Revenue receipts + non-debt capital receipts) = total borrowing.
2. Primary deficit = Fiscal deficit − Interest payments.
3. Budget deficit = Total expenditure − Total receipts.

Short trick: Revenue minus revenue = Revenue deficit; FD = borrowing; PD = FD − interest.

Concept: Public debt and interest are fixed in money terms; when prices rise, the real value of these payments falls.

1. Dalton: the direct real burden is the loss of economic welfare from transfers to (foreign) creditors – it falls with inflation because each rupee repaid buys less.
2. Inflation thus transfers wealth from creditors (bond-holders) to the debtor (government).
3. With falling prices (deflation) the real burden rises.

Short trick: Inflation helps debtors – government's real debt burden falls.

Concept: In the Indian sense, deficit financing means financing the budget gap by borrowing from the central bank (creation of new money).

1. RBI credit to government expands reserve money and hence money supply.
2. Excess money supply can cause inflation if output does not rise.
3. It does not directly reduce taxes or money supply.

Short trick: Deficit financing = printing new money → ↑ money supply → risk of inflation.

Concept: Goods with high income elasticity of demand (luxuries) are bought mainly by the rich, so they can be taxed at higher rates.

1. Higher rates on such goods make the tax system progressive (ability-to-pay principle).
2. Demand and tax revenue from them grow faster than income – revenue is buoyant/elastic.
3. Necessities (low income elasticity) should be taxed lightly to protect the poor.

Short trick: High income elasticity = luxury = tax it more.

Concept: The services (tertiary) sector has had the largest and fastest-growing share in India's GVA – about 55% now, up from about 30% in 1950-51.

1. Agriculture's share has fallen to about 17–18%.
2. Manufacturing has stayed roughly 15–17% of GVA.
3. IT, finance, trade, transport and communication drove the services boom after 1991.

Short trick: India = service-led growth (skipped the manufacturing stage).

Concept: A tariff is a tax on internationally traded goods – customs duty levied on imports and/or exports.

1. Import duties protect domestic industry and raise revenue.
2. Export duties are also tariffs (e.g., on raw materials to discourage their export).
3. Customs duty is the general name for both.

Short trick: Tariff = customs duty on imports and exports.

Concept: Forestalling (hedging/forward cover) means fixing the exchange rate in advance (e.g., by a forward contract or leads and lags in payment) so that future exchange-rate changes cannot cause loss.

1. An importer due to pay dollars later buys dollars forward to guard against depreciation of the rupee.
2. Its aim is to cover (protect against) foreign-exchange risk, not to accept or profit from it.
3. Speculation is the opposite – deliberately taking an open position to profit from rate changes.

Short trick: Hedging/forestalling = cover the risk; speculation = take the risk.

Concept: Under flexible rates, a BoP deficit causes the domestic currency to depreciate, making exports cheaper and imports dearer until the deficit disappears.

1. Gold standard/fixed rates: adjustment via price level (Hume's price–specie flow) or income (Keynesian).
2. Flexible rates: adjustment via the exchange rate itself (elasticity approach, Marshall–Lerner condition).

Short trick: Fixed rate → prices/income adjust; flexible rate → exchange rate adjusts.

Concept: Protection = measures that shield domestic producers from foreign competition.

1. Tariffs, import quotas and exchange control all restrict imports.
2. Excise duty is a tax on goods produced within the country; it falls on domestic goods and so does not protect them from imports.

Short trick: Excise = domestic production tax → not protection.

Concept: The Doha Development Round (launched 2001) had agriculture as its central and most contentious issue.

1. Disputes: farm subsidies of the US/EU, market access, special safeguard mechanism for developing countries.
2. Talks collapsed in 2008 (Geneva) mainly over agricultural SSM between India/China and the US.
3. TRIPS and services (GATS) came from the earlier Uruguay Round.

Short trick: Doha = 'Development Round' stuck on agriculture.

Concept: The Human Development Report (with HDI) is published annually by the UNDP since 1990.

1. It was conceived by Mahbub ul Haq with Amartya Sen's capability approach.
2. World Bank – World Development Report; IMF – World Economic Outlook; UNICEF – State of the World's Children.

Short trick: HDR/HDI → UNDP (1990, Mahbub ul Haq).

Concept: Since 2014 (Urjit Patel Committee) India measures headline inflation by the all-India Consumer Price Index (Combined), which RBI targets at 4% ± 2% under flexible inflation targeting.

1. CPI (Combined: rural + urban) is compiled monthly by NSO/MoSPI.
2. WPI (Office of Economic Adviser, DPIIT) is still published as ‘WPI inflation’, but since 2014 it is no longer the headline/policy measure – so the official headline method is CPI.
3. Fisher's ideal index is a formula, not India's official measure; CPI-IW is used for DA of workers.

Short trick: Old headline = WPI; since 2014 headline/RBI target = CPI-Combined.
