Economic concepts for CDS

Economy is a small block in CDS GK, but it is a predictable one. The questions test definitions: what GNP adds to GDP, what fiscal deficit measures, which RBI tool does what, and whether a tax is direct or indirect. The options are built from near-miss definitions, so vague familiarity loses marks. Precise one-line meanings win them.

Learn each concept with one small worked number. Once you have calculated a fiscal deficit yourself, you will not confuse it with revenue deficit in the exam hall.

National income

GDP by the expenditure method is C + I + G + (X − M): consumption, investment, government spending and net exports. The other two methods add up value added (production method) or incomes (income method). In India, national accounts are released by the National Statistics Office under the Ministry of Statistics and Programme Implementation.

Worked example

Suppose an economy has consumption 60, investment 20, government spending 15, exports 10 and imports 12 (in ₹ lakh crore).

1. GDP = 60 + 20 + 15 + (10 − 12) = 93.
2. Residents earn 4 abroad; foreigners earn 6 here. Net factor income = −2, so GNP = 91.
3. Depreciation is 8, so NNP at market prices = 83.
4. Indirect taxes minus subsidies = 5, so national income = 78.

If nominal GDP is 330 and real GDP is 300, the deflator is 330 ÷ 300 × 100 = 110: prices are 10% above the base year.

Inflation

Inflation is a sustained rise in the general price level. Money buys less.

India measures inflation mainly through the Consumer Price Index (CPI), compiled by the NSO, and the Wholesale Price Index (WPI), compiled by the Office of the Economic Adviser in the Ministry of Commerce and Industry. WPI covers goods only, not services. Since 2016 the RBI has targeted CPI inflation of 4%, within a band of 2–6%.

Fiscal policy: the Budget and deficits

Fiscal policy is the government's use of taxing, spending and borrowing. The Budget is the "annual financial statement" under Article 112.

Suppose revenue receipts are 30, non-debt capital receipts (loan recoveries, disinvestment) are 1, revenue expenditure is 37 (of which interest is 11) and capital expenditure is 10.

• Total expenditure = 37 + 10 = 47.
• Fiscal deficit = 47 − (30 + 1) = 16.
• Revenue deficit = 37 − 30 = 7.
• Primary deficit = 16 − 11 = 5.

The Fiscal Responsibility and Budget Management (FRBM) Act, 2003 set a path for bringing deficits down.

Monetary policy and RBI tools

Monetary policy controls the cost and supply of money. Since 2016 the policy rate is set by a six-member Monetary Policy Committee: three from the RBI, including the Governor, who has a casting vote, and three appointed by the Central Government.

These are quantitative tools. Qualitative tools include margin requirements, selective credit controls and moral suasion.

Money supply

• M1 (narrow money) = currency with the public + demand deposits with banks + other deposits with the RBI.
• M3 (broad money) = M1 + time deposits with banks.
• M1 is the most liquid; M3 is the measure most often quoted.

Banking milestones

Payments banks accept deposits and offer remittances but cannot lend. Small finance banks lend mainly to small businesses and the unorganised sector.

Taxes

A progressive tax takes a higher share as income rises (income tax slabs). A regressive tax takes a larger share of a poor person's income (most indirect taxes). GST came into force on 1 July 2017 under the 101st Amendment (2016). It has three parts: CGST, SGST and IGST (on inter-state supply). The GST Council under Article 279A is chaired by the Union Finance Minister.

Common confusions

• CRR vs SLR: CRR is held with the RBI; SLR is held by the bank itself.
• Repo vs reverse repo: repo is the RBI lending; reverse repo is the RBI borrowing. The SDF has replaced reverse repo as the floor.
• Deflation vs disinflation: falling prices vs a falling rate of price rise.
• Fiscal vs revenue deficit: fiscal is total borrowing; revenue shows only the day-to-day gap.
• GDP vs GNP: territory vs residents.

Practice MCQs

1. GNP equals GDP plus (a) net factor income from abroad (b) net indirect taxes (c) depreciation (d) subsidies
2. If nominal GDP is 440 and real GDP is 400, the GDP deflator is (a) 90 (b) 104 (c) 110 (d) 140
3. Fiscal deficit minus interest payments gives the (a) revenue deficit (b) monetised deficit (c) budget deficit (d) primary deficit
4. A fall in the rate of inflation while prices still rise is called (a) deflation (b) disinflation (c) stagflation (d) reflation
5. The reserve that banks keep with the RBI is the (a) CRR (b) SLR (c) repo (d) MSF
6. To control inflation, the RBI would (a) cut the repo rate (b) buy government securities (c) lower the SLR (d) raise the CRR
7. Which index excludes services? (a) CPI (b) WPI (c) GDP deflator (d) all include services
8. Fourteen banks were nationalised in (a) 1949 (b) 1955 (c) 1969 (d) 1980
9. Which is a direct tax? (a) GST (b) Customs duty (c) Excise duty (d) Corporation tax
10. Revenue expenditure 50, revenue receipts 42, capital expenditure 12, non-debt capital receipts 2. The fiscal deficit is (a) 8 (b) 16 (c) 18 (d) 20

Answers:

1. (a) Depreciation is subtracted to reach NNP, not added.
2. (c) 440 ÷ 400 × 100 = 110.
3. (d) Primary deficit.
4. (b) Deflation means prices actually fall.
5. (a) SLR is held by the bank itself.
6. (d) Raising the CRR takes money out of the banking system. The other three add money.
7. (b) WPI covers goods only.
8. (c) Six more followed in 1980.
9. (d) The company that pays it bears it.
10. (c) Total expenditure 62 − (42 + 2) = 18. The revenue deficit is 8.

What to do next

• Write the four national income steps from memory and re-run the worked example with your own numbers.
• Recite the three deficits with formulas.
• Say which way each RBI tool moves when inflation is high.
• Learn the banking timeline from 1935 to 1982.

Then read the Indian economy for CDS for planning, the 1991 reforms and schemes. The constitutional side of the Budget and the Finance Commission is in government and constitutional bodies.
