Economic Terms – Tripura PSC General Awareness & Current Affairs
(Study Notes – Markdown Format)
1. Simple Explanation
Economic terms are the building blocks of any economy. They help you understand how a country’s wealth is produced, measured, and managed. For the PSC exam, you need to grasp the definition, how it is used, and why it matters.
2. Key Points
| Term | Definition | How it is Used | Why it Matters (PSC Context) |
|---|---|---|---|
| Gross Domestic Product (GDP) | Total value of all final goods & services produced inside a country in a given period. | Indicator of economic size & growth. | PSC exam often asks “What is the GDP?” or “How is GDP affected by X?”. |
| Gross National Product (GNP) | GDP + income earned by residents abroad – income earned abroad by residents. | Measures national income. | Useful for comparing living standards. |
| Inflation | Sustained rise in general price level. | Calculated via CPI or PPI. | Determines cost‑of‑living and monetary policy. |
| Deflation | Sustained fall in general price level. | Signs of economic slowdown. | PSC questions may ask causes & consequences. |
| Unemployment Rate | % of labor force that is jobless & actively seeking work. | Labour market health indicator. | Often featured in current affairs. |
| Fiscal Policy | Government’s use of taxation & spending to influence economy. | Expansionary (tax cuts/spending) or contractionary (tax hikes/spending cuts). | Common PSC topic (e.g., “what is the fiscal deficit?”). |
| Monetary Policy | Central bank’s control of money supply & interest rates. | Tools: repo rate, reverse repo, cash reserve ratio. | PSC exam covers “what is the repo rate?” etc. |
| Exchange Rate | Value of one currency relative to another. | Determines trade competitiveness. | PSC often asks “what is the current INR‑USD rate?” |
| Balance of Payments (BOP) | Record of all international transactions (current & capital). | Indicates international economic health. | Useful for understanding foreign reserves. |
| Current Account | Sub‑component of BOP (trade in goods/services, income, transfers). | Shows trade surplus/deficit. | PSC questions on trade deficit. |
| Capital Account | Sub‑component of BOP (capital transfers, investment flows). | Indicates foreign investment inflow/outflow. | PSC may ask: “What is FDI?” |
| Debt‑to‑GDP Ratio | Government debt / GDP. | Measures debt sustainability. | PSC exam asks about debt levels. |
| Consumer Price Index (CPI) | Weighted basket of goods & services used to measure inflation. | Basis for cost‑of‑living adjustments. | Often referenced in current affairs. |
| Producer Price Index (PPI) | Prices of goods at the production stage. | Indicates inflationary pressures upstream. | Helps predict CPI changes. |
| Composite Economic Index (CEI) | Regional indicator of economic health (e.g., CEI‑III for Indian states). | Shows growth rate, employment, inflation, and fiscal deficit. | Useful for state‑level PSC exams. |
| Skill Development & Employment Scheme (SDE) | Government programmes to train & employ youth. | Directly related to employment statistics. | Frequently mentioned in current affairs. |
| Sustainable Development Goals (SDGs) | UN goals for 2030 covering economic, social, & environmental targets. | Benchmark for national progress. | PSC may ask about India’s progress on SDGs. |
3. Worked Example
Example: Calculating Inflation Rate using CPI
| Year | CPI (Base 2019 = 100) |
|---|---|
| 2019 | 100 |
| 2020 | 110 |
Formula:
[
\text{Inflation Rate} = \frac{\text{CPI}{2020} - \text{CPI}{2019}}{\text{CPI}_{2019}} \times 100%
]
Calculation:
[
\frac{110 - 100}{100} \times 100% = \frac{10}{100} \times 100% = 10%
]
Interpretation:
- Prices have risen by 10% from 2019 to 2020.
- This indicates moderate inflation.
- For PSC, you might be asked to explain what a 10% inflation rate means for wages, cost of living, and central bank policy.
