Economic Terms – Study Notes
(NABARD Development Assistant – General Awareness & Current Affairs)
1. Simple Explanation
Economic terms are the building blocks of macro‑economics. They help us understand how a country’s economy functions, how its growth is measured, and how policy decisions affect production, employment, and prices.
2. Key Economic Terms
| Term | Simple Definition | Why It Matters | Typical Indicator |
|---|---|---|---|
| Gross Domestic Product (GDP) | Total value of all final goods & services produced inside a country in a given period. | Measures the size & health of the economy. | National accounts, quarterly/annual GDP releases |
| Gross National Product (GNP) | GDP + income earned by residents abroad – income earned by foreigners within the country. | Shows national income, including overseas earnings. | Used for national income accounting |
| Gross National Income (GNI) | GNP + net primary income (e.g., dividends, interest). | Alternative to GNP; includes income from abroad. | Development indicators (UN, World Bank) |
| Inflation | Sustained rise in general price level. | Reduces purchasing power, impacts savings, wages. | CPI, PPI, core inflation |
| Deflation | Sustained fall in general price level. | Can signal economic slowdown, increases real debt burden. | CPI, core inflation |
| Consumer Price Index (CPI) | Weighted average of prices of consumer goods/services. | Primary measure of inflation. | CPI releases |
| Producer Price Index (PPI) | Weighted average of prices received by producers. | Indicates input cost pressures. | PPI releases |
| Unemployment Rate | % of labor force that is jobless & actively searching. | Indicator of labor market health. | Labour force surveys |
| Fiscal Deficit | Government expenditure > receipts (excluding debt). | Indicates government borrowing needs. | Budget statements |
| Current Account Balance | Net of trade in goods & services + net primary income + net secondary income. | Shows external competitiveness. | Balance of payments data |
| Savings Rate | % of disposable income saved. | Determines investment potential. | National accounts |
| Interest Rate | Cost of borrowing money. | Influences investment, consumption, inflation. | RBI repo rate, policy rates |
| Exchange Rate | Value of one currency relative to another. | Affects trade competitiveness, inflation. | Forex markets |
3. Worked Example – Calculating Real GDP
Scenario
The economy in year 2024 produced:
- 10,000 units of Product A at price ₹100 each
- 5,000 units of Product B at price ₹200 each
Price of Product A in the base year (2020) = ₹80
Price of Product B in the base year (2020) = ₹150
Step 1 – Compute Nominal GDP (2024)
[
\text{Nominal GDP} = (10{,}000 \times 100) + (5{,}000 \times 200) = 1{,}000{,}000 + 1{,}000{,}000 = ₹2{,}000{,}000
]
Step 2 – Compute Real GDP (2024, base year 2020)
Use base‑year prices to adjust for inflation.
[ \text{Real GDP} = (10{,}000 \times 80) + (5{,}000 \times 150) = 800{,}000 + 750{,}000 = ₹1{,}550{,}000 ]
Step 3 – Compute GDP Deflator
[
\text{GDP Deflator} = \frac{\text{Nominal GDP}}{\text{Real GDP}} \times 100 = \frac{2{,}000{,}000}{1{,}550{,}000} \times 100 \approx 129.03
]
Interpretation
- Nominal GDP increased from ₹1,500,000 (2020) to ₹2,000,000 (2024).
- Real GDP increased from ₹1,500,000 to ₹1,550,000 – a modest 3.33% real growth.
- GDP deflator > 100 indicates price increase (inflation) between 2020 and 2024.
4. Quick Revision Summary
- GDP = total value of goods/services inside the country.
- GNP/GNI = GDP + income from abroad.
- Inflation = rise in price level; measured by CPI or PPI.
- Deflation = fall in price level; signals possible recession.
- Unemployment Rate = % of labor force that is jobless.
- Fiscal Deficit = government spending > revenue.
- Current Account = trade + income flows; indicates external balance.
- Real GDP = Nominal GDP adjusted for price changes (base‑year prices).
- GDP Deflator = price level relative to base year; >100 = inflation.
- Exchange Rate influences export competitiveness and inflation.
Use these terms to interpret economic news, policy speeches, and statistical releases. Keep the definitions handy while reading RBI reports, the Ministry of Finance budget, and international trade data.
