Economic Terms – Study Notes
(For Tripura Police Sub‑Inspector Exam – General Awareness & Current Affairs)
1. Simple Explanation
Economic terms are the building blocks of any discussion on the economy – how a country produces goods, distributes income, and manages money. Understanding these terms helps you interpret news, policy decisions, and economic data that affect your community and the nation.
2. Key Economic Terms & Concepts
| Term | Short Definition | Why It Matters |
|---|---|---|
| Gross Domestic Product (GDP) | Total value of all final goods & services produced within a country’s borders in a given period. | Indicator of economic size & health. |
| Gross National Product (GNP) | Total value of all goods & services produced by a country’s residents, regardless of location. | Shows national income generated abroad. |
| Inflation | General rise in price levels over time. | Affects purchasing power & cost of living. |
| Deflation | General fall in price levels. | Usually signals weak demand & can increase real debt burden. |
| Fiscal Policy | Government decisions on taxation and spending. | Controls aggregate demand & redistributes resources. |
| Monetary Policy | Central bank actions (interest rates, money supply). | Influences inflation, credit, and economic growth. |
| Interest Rate | Cost of borrowing money, expressed as a percentage. | Drives investment, consumption, and savings. |
| Exchange Rate | Value of one currency relative to another. | Impacts trade balances & inflation. |
| Balance of Payments (BOP) | Record of all international transactions (current & capital). | Shows country’s financial health with the rest of the world. |
| Current Account | Sub‑component of BOP: trade in goods & services, income, transfers. | Indicator of trade balance. |
| Capital Account | Sub‑component of BOP: cross‑border investment flows. | Reflects capital inflows/outflows. |
| Public Debt | Total money owed by the government. | Affects fiscal sustainability & future taxes. |
| Deficit / Surplus | Difference between government spending & revenue. | Determines borrowing needs or fiscal excess. |
| Employment Rate / Unemployment Rate | % of labor force that is employed or jobless. | Social welfare & productivity indicator. |
| Human Development Index (HDI) | Composite of life expectancy, education, and income. | Measures overall development beyond GDP. |
| Consumer Price Index (CPI) | Basket of goods & services used to track inflation. | Basis for cost‑of‑living adjustments. |
| Producer Price Index (PPI) | Prices received by producers for goods sold. | Early indicator of inflation. |
| Supply‑Side & Demand‑Side Economics | Supply: production capacity; Demand: consumer willingness to buy. | Explain price changes & economic cycles. |
| Elasticity | Responsiveness of quantity demanded/supplied to price changes. | Helps gauge market reactions. |
| Subsidy / Tax Incentive | Government financial aid or tax breaks to firms/industries. | Encourages growth in targeted sectors. |
| Competition/Monopoly | Market structure affecting pricing and output. | Influences consumer welfare. |
3. Worked Example – Calculating GDP (Expenditure Approach)
Scenario:
The Tripura government released the following data for Q2 2025 (in ₹ crore):
| Component | Value (₹ crore) |
|---|---|
| Consumption (C) | 18,500 |
| Investment (I) | 3,200 |
| Government Spending (G) | 4,800 |
| Net Exports (X – M) | 400 – 1,100 = –700 |
Task: Compute GDP for Q2 2025.
Step‑by‑Step:
- Formula (Expenditure Approach):
[ \text{GDP} = C + I + G + (X - M) ] - Insert Values:
[ \text{GDP} = 18,500 + 3,200 + 4,800 + (-700) ] - Add/Subtract:
[ \text{GDP} = 18,500 + 3,200 + 4,800 - 700 = 26,800 \text{ ₹ crore} ]
Interpretation:
- GDP of ₹26,800 crore indicates the total value of goods & services produced in Q2 2025.
- A negative net export component (trade deficit) shows that imports exceeded exports by ₹700 crore.
4. Quick Revision Summary
- GDP – Size & health of domestic economy.
- GNP – National income including overseas earnings.
- Inflation – Rising prices → lower purchasing power.
- Deflation – Falling prices → potential economic slowdown.
- Fiscal Policy – Taxes & spending decisions.
- Monetary Policy – Central bank’s control of money supply & rates.
- Interest Rate – Borrowing cost; higher rates curb inflation.
- Exchange Rate – Currency value; influences imports/exports.
- Balance of Payments – Record of cross‑border transactions.
- Public Debt – Money owed by government; impacts future budgets.
- Deficit / Surplus – Breach between spending & revenue.
- Employment Indicators – Gauge workforce participation.
- HDI – Broad development metric.
- CPI & PPI – Inflation gauges.
- Supply‑Side vs Demand‑Side – Explain price dynamics.
- Elasticity – Sensitivity of quantity to price changes.
- Subsidies & Tax Incentives – Tools to promote sectors.
- Market Structures – Competition vs monopoly affect consumer welfare.
Tip for SI Exam:
- Memorize definitions and real‑world examples (e.g., 2024 inflation rate, RBI’s policy rate changes).
- Relate terms to current affairs: how a policy change (e.g., subsidy on solar panels) influences GDP, employment, and inflation.
- Practice quick calculations (GDP, CPI change) as you did above.
Good luck with your preparation!
