Economic Terms – Study Notes for Kerala Police Sub‑Inspector (SI)
Why they matter
Knowledge of basic economic terms helps you understand news, policy decisions, and their impact on society – all of which are part of the General Awareness section of the SI exam.
1. Simple Explanation
| Term | What it means (plain language) |
|---|---|
| Gross Domestic Product (GDP) | Total value of all goods & services produced inside India in a year. Think of it as India’s “income” from its economy. |
| Real GDP | GDP adjusted for inflation – shows true growth. |
| GDP Growth Rate | Percentage change of real GDP year‑on‑year. |
| Gross National Income (GNI) | Total income earned by residents of India, including overseas earnings. |
| Inflation / CPI | Rise in general price levels, measured by the Consumer Price Index (CPI). |
| Producer Price Index (PPI) | Rise in prices of goods at the production stage. |
| Purchasing Power Parity (PPP) | Exchange rate that equalises the purchasing power of two currencies. |
| Rupee‑USD Exchange Rate | Market (spot) rate of rupee to US dollar. |
| Interest Rate (Repo Rate) | Rate at which RBI lends money to banks; influences borrowing cost. |
| Fiscal Deficit | When government spending > revenue (taxes + other receipts). |
| Debt‑to‑GDP Ratio | Total public debt ÷ GDP – shows debt load relative to economy size. |
| Goods & Services Tax (GST) | Uniform indirect tax on goods & services; replaces multiple state & central taxes. |
| Value Added Tax (VAT) | State‑level tax on goods; replaced by GST. |
| Tax‑On‑Tax (TOT) | Burden of taxes on already taxed goods (e.g., excise + VAT). |
| GST Rate Schedules | 0%, 5%, 12%, 18%, 28% + CGST/SGST/UGST. |
| Central Pay Commission (CPC) | Body recommending pay scales for central govt. employees. |
| Reserve Bank of India (RBI) | India’s central bank; controls monetary policy. |
| Foreign Direct Investment (FDI) | Investment by foreigners in Indian businesses. |
| Foreign Portfolio Investment (FPI) | Investment in Indian stocks & bonds (not a long‑term stake). |
| Budget | Annual plan of government revenue & expenditure; presented by Finance Minister. |
| Capital Expenditure (Capex) | Spending on infrastructure, machinery, etc. |
| Current Expenditure (Cpex) | Day‑to‑day spending: salaries, subsidies, etc. |
2. Key Points (Bullet‑List)
| Topic | Key Points |
|---|---|
| GDP & Growth | • Real GDP growth is the primary indicator of economic health. • Fiscal policy (budget) and monetary policy (repo rate) influence growth. • Growth > 6% is considered strong; < 5% is slow. |
| Inflation | • CPI & PPI show consumer & producer price movements. • RBI’s inflation target: 4 % ± 2 %. |
| Monetary Policy | • Repo rate: lowers → cheaper loans → stimulates growth. • Reverse repo rate: raises → collects excess liquidity. |
| Fiscal Policy | • Deficit = Expenditure – Revenue. • Target deficit: < 3 % of GDP (Constitutional limit). |
| GST | • Unified tax: 14‑slab structure (adhoc). • CGST (Central), SGST (State), IGST (International). |
| Expenditure | • Capital Expenditure (Capex) → infrastructure. • Current Expenditure (Cpex) → salaries, subsidies. |
| Debt Management | • Debt‑to‑GDP ratio < 60 % is considered “manageable”. |
| Exchange Rate | • RBI intervenes to stabilise rupee; central bank reserves affect it. |
| FDI/FPI | • FDI inflow boosts employment, technology transfer. • FPI is volatile; used for short‑term gains. |
| Budget | • Contains Revenue (taxes, non‑taxes) & Expenditure (Capex, Cpex). • Highlights Deficit or Surplus status. |
| CPC & Pay | • Determines pay scales of SI, DCP, etc. • Pay bands: 1 to 8 (e.g., Rank 1 to 8). |
3. Worked Example
Example: Calculating Inflation Rate (CPI)
Suppose the CPI for March 2024 is 288.5 and for March 2023 it was 277.8.
[ \text{Inflation Rate} = \frac{\text{CPI}{2024} - \text{CPI}{2023}}{\text{CPI}_{2023}} \times 100 ]
[ = \frac{288.5 - 277.8}{277.8} \times 100 = \frac{10.7}{277.8} \times 100 \approx 3.85% ]
Interpretation:
The consumer price level rose by ~3.85% year‑on‑year, which is within RBI’s 4 % ± 2 % target band.
Example: GDP Growth Calculation
- Real GDP 2022‑23: ₹312 trn
- Real GDP 2023‑24: ₹328 trn
[ \text{Growth Rate} = \frac{328 - 312}{312} \times 100 = \frac{16}{312} \times 100 \approx 5.13% ]
Interpretation:
India’s economy grew by ~5.1% in that year, considered moderate growth.
