Economy Key Terminologies — Inflation
1. Previous Year Questions (UPSC)
Context: Understanding key inflation terminologies is crucial for UPSC preparation. The following terms have been asked in previous years' examinations.
| Year | Term | Explanation |
|---|---|---|
| 2021 | Inflation | Inflation is a sustained increase in the general price level of goods and services in an economy over a period of time. It is typically measured by an index of consumer prices, such as the Consumer Price Index (CPI) or the Wholesale Price Index (WPI). |
| 2021 | Economic Recession | An economic recession is a period of general economic decline, typically characterized by a decrease in gross domestic product (GDP), employment, and trade. It is usually marked by a slowdown in economic activity, a rise in unemployment, and a decline in consumer spending. |
| 2021 | Demand Pull Inflation | Demand-pull inflation is caused by an increase in demand and when the demand in the economy outgrows the supply in the economy. It can be summed up as a condition of "too much money chasing too few goods". |
| 2021 | Expansionary Policies | Money in the market rises when the government spends more freely. It leads to an increase in demand for the goods and fuels demand-pull inflation. |
| 2021 | Fiscal Stimulus | Government policies aimed at increasing aggregate demand and stimulating economic growth during a recession or period of low economic activity. Fiscal stimulus may take the form of tax cuts, increased government spending, or other measures designed to stimulate consumer spending and investment. |
| 2021 | Inflation-Indexing Wages | It means wages are linked to inflation to ensure that wages change when inflation changes in the economy. Such indexing is provided to reduce the effect of inflation on wages. It can not lead to demand pulling inflation in the economy. |
| 2021 | Purchasing Power | Purchasing power is the value of a currency expressed in terms of the number of goods or services that one unit of money can buy. Consumers feel more confidence and spend more when they have a better income. |
| 2020 | Consumer Price Index (CPI) | A comprehensive measure used for estimation of price changes in a basket of goods and services representative of consumption expenditure in an economy is called consumer price index. |
| 2020 | Wholesale Price Index (WPI) | Wholesale stage i.e. goods that are sold in bulk and traded between organizations instead of consumers. WPI is used as a measure of inflation in some economies. |
| 2013 | Debtors | A debtor is a person or an entity that owes money to another, which could be any individual or institution (including the government). In most cases, the debtor has to pay interest on debt along with the principal debt. A debtor is commonly known as a borrower, but when a company's debt is in the form of securities, it is called an issuer. |
| 2013 | Bond-holders | A bondholder is an investor or the owner of debt securities that are typically issued by corporations and governments. Bondholders are essentially lending money to the bond issuers. In return, bond investors receive their principal i.e. initial investment back when the bonds mature. |
2. Important Terms in News
Context: These inflation-related terms frequently appear in news and policy discussions, making them essential for UPSC aspirants to understand.
Types of Inflation
- Cost Push Inflation: Price rise due to increased cost of inputs leads to cost push inflation. Eg. increase in crude oil prices leads to increased cost for transport companies.
- Demand Pull Inflation: Caused by an increase in demand when demand outgrows supply. "Too much money chasing too few goods".
- Stagflation: It refers to persistent high inflation, high unemployment and low growth resulting in a stagnant economy.
- Hyper-Inflation: A situation of extremely rapid inflation (reaching 100% per year or more), often resulting from a condition of economic or political breakdown.
- Skewflation: It refers to the relative price rise of one or a group of commodities. Eg. Onion or Tomato inflation in India.
Inflation Measurement
- Headline Inflation: It is the measure of total inflation within an economy. It includes price rise in food, fuel and all other commodities.
- Core Inflation: Core inflation excludes food and fuel items from headline inflation. Core inflation excludes these items because their prices are much more volatile.
Inflation Related Concepts
- Disinflation: Disinflation is a decrease in the rate of inflation – a slowdown in the rate of increase of the general price level of goods and services in a nation's gross domestic product over time.
- Deflation: When the overall price level decreases so that inflation rate becomes negative, it is called deflation. It is the opposite of the often-encountered inflation.
- Reflation: It is a policy which is enacted after a period of economic slowdown or contraction so as to expand output, stimulate spending and curb the effects of deflation.
Other Important Terms
- Shrinkflation: Shrinkflation is the reduction in the size of a product in response to rising production costs or market competition. Rather than increase the price of a product, the company simply offers a smaller package for the same sticker price.
- Inflationary Gap: The excess of total government spending above the national income (i.e., fiscal deficit) is known as the inflationary gap.
- Deflationary Gap: The shortfall in total spending of the government (i.e., fiscal surplus) over the national income creates deflationary gaps in the economy.
- Inflation Premium: The bonus brought by inflation to the borrowers is known as the inflation premium.
- Giffen Goods: Giffen goods are non-luxury items that generate higher demand when prices rise, creating an upward-sloping demand curve contrary to standard laws of demand.

- Stagflation: High inflation + high unemployment + low growth
- Headline vs Core Inflation: Total inflation vs excluding food and fuel
- Disinflation vs Deflation: Slower inflation vs negative inflation
- Inflationary Gap: Fiscal deficit (excess spending over income)
- Deflationary Gap: Fiscal surplus (shortfall in spending)
