Inflation PYQs – Economics, SSC & Railway

Answer: Option 2 — Shrinkflation denotes a phenomenon where producers reduce the size or quantity of a product while maintaining its price, often to cope with rising input costs, which may distort inflation measurements and consumer welfare assessments.
Shrinkflation = the packet gets smaller while the price tag stays the same, so the price per gram rises without the customer noticing.
It is a hidden form of inflation, and the price index misses it unless the statistician corrects for the smaller pack.
Revision note — Shrinkflation and the hidden faces of inflation
• The word joins shrink + inflation; it was popularised by the British economist Pippa Malmgren around 2013.
• Producers use it when input costs (wheat, edible oil, packaging, fuel) rise but a visible price hike would hurt sales, especially at the ₹5 and ₹10 price points that Indian FMCG brands protect.
• Indian examples cited in 2022: the Parle-G and Haldiram's packs, Vim bars and Dettol soaps became lighter at the same price.
• Its cousin skimpflation keeps the size but lowers the quality or service; stealth inflation is the umbrella term for both.
• Inflation is a sustained rise in the general price level; hyperinflation is an extreme, runaway rise; stagflation is high inflation with stagnant growth and high unemployment.
• India measures headline inflation by the CPI (Combined), released by the NSO (MoSPI); the WPI comes from the Office of the Economic Adviser, DPIIT.
• The RBI's inflation target is CPI inflation of 4 per cent, ± 2 per cent.
Do not mix these up
• Shrinkflation vs deflation — shrinkflation hides a price rise per unit; deflation is a genuine fall in the general price level.
• Demand-pull vs cost-push inflation — the first comes from excess demand, the second from rising costs of inputs; shrinkflation is a producer's response to the second.
Also asked from this topic: the meaning of stagflation (inflation plus unemployment); the term for a runaway rate of inflation (hyperinflation); India's headline inflation index (CPI Combined).

Answer: Option 4 — Stagflation
Stagnation + inflation — prices rising while output stays flat and unemployment stays high, all at the same time.
Revision note — Inflation and its types
• The word was coined by the British MP Iain Macleod in 1965.
• The textbook case is the oil shocks of the 1970s: a supply shock pushes costs and prices up while output falls.
• Stagflation breaks the Phillips curve trade-off, under which inflation and unemployment are supposed to move in opposite directions.
• It is hard to treat — tightening to fight inflation deepens the slump, and stimulus to revive growth feeds the inflation.
• Demand-pull inflation is aggregate demand outrunning supply; cost-push inflation is a rise in input costs. Stagflation is the classic cost-push outcome.
• Hyperinflation is an extremely high and accelerating price rise (Weimar Germany in the 1920s, Zimbabwe in the 2000s); deflation is a general fall in prices.
Do not mix these up
• Recession vs depression — a recession is usually two consecutive quarters of negative GDP growth; a depression is far deeper and longer, as in 1929.
• Stagflation vs recession — in an ordinary recession prices normally slow or fall; in stagflation they surge even as output stagnates.
• Reflation vs inflation — reflation is a deliberate policy of lifting demand and prices after a slump, so it is a remedy; inflation is the price rise itself.
Also asked from this topic: what stagflation is a situation of (inflation plus unemployment); the name for a very high price rise (hyperinflation); the result of demand outrunning supply (demand-pull).

Correct Answer: Inflation + unemployment (Option 4)
Stagflation is an economic phenomenon where high inflation and high unemployment (economic stagnation) occur simultaneously. It defies the traditional Phillips Curve relationship, which suggests inflation and unemployment move in opposite directions. Stagflation was notably experienced globally during the 1970s oil crisis.
Why others are wrong:
- Inflation + trade surplus: A trade surplus reflects export strength; unrelated to stagflation.
- Inflation + rise in employment: Rising employment is positive economic growth, opposite of stagnation.
- Inflation + rising GDP: A rising GDP indicates economic expansion, not stagnation.

Correct Answer: Combined Consumer Price Index (CPI) — Option (a)
The Consumer Price Index (CPI) — Combined is used to measure headline inflation in India. About Headline Inflation in India: Since 2014, the Reserve Bank of India (RBI) has adopted CPI-based inflation as the headline measure for its monetary policy framework; The Urjit Patel Committee (2014) recommended CPI as the nominal anchor for monetary policy; What is CPI: Consumer Price Index measures changes in prices of a representative basket of goods and services consumed by households; Types of CPI in India: CPI (Combined): National average for rural + urban populations; CPI (Rural): Prices in rural areas; CPI (Urban): Prices in urban areas; Base year: Currently 2012 (base year = 2012, index = 100); Compiled by: Ministry of Statistics and Programme Implementation ( MoSPI ); Inflation targeting framework: Since 2016, RBI operates under a formal inflation targeting framework; Target: CPI inflation of 4% with a tolerance band of ±2% (i.e., 2%-6%); About other price indices: GDP Deflator: Measures price changes for ALL goods and services in GDP; broadest measure of inflation; used for calculating real GDP; NOT the headline measure; Index of Industrial Production (IIP): Measures PRODUCTION (not prices) in industrial sectors; NOT an inflation measure; Wholesale Price Index (WPI): Measures prices at the wholesale/producer level; Used to be the headline measure before 2014; Still used alongside CPI but is NOT the current headline measure; Key difference: CPI measures prices at consumer/retail level; WPI measures prices at wholesale/producer level; CPI better captures cost of living for common people.
Option (b) GDP Deflator — Incorrect: The GDP Deflator is NOT used as the headline measure of inflation in India; it is the broadest measure of inflation (covers all goods and services in GDP — consumption, investment, government spending, exports, minus imports); it is used for calculating real GDP from nominal GDP; however, for monetary policy, India uses CPI as the headline inflation measure (since 2014). The candidate incorrectly selected this option.
Option (c) Index of Industrial Production (IIP) — Incorrect: The Index of Industrial Production (IIP) is NOT an inflation index at all — it measures the VOLUME/QUANTITY of industrial output in India; it tracks changes in industrial production (manufacturing, mining, electricity); it does NOT measure price changes; the headline inflation measure in India is the Consumer Price Index (CPI).
Option (d) Wholesale Price Index (WPI) — Incorrect: While the WPI was previously used as India's headline inflation measure (before 2014), it is NO LONGER the primary headline measure; since 2014, based on the Urjit Patel Committee recommendation, India has adopted the Consumer Price Index (CPI) as the headline measure for monetary policy; WPI still exists and is tracked but is NOT the current headline measure.

Price Stabilisation Fund (PSF)
Established by Government of India in2014-15.
Purpose: Regulate prices of agri-horticultural commodities.
Helps control price volatility of perishable items like onions, potatoes, pulses.
Answer: Option 4 → 2014-15

Correct Answer: Wholesale Price Index — Option (d)
The Wholesale Price Index (WPI) measures the average change in the prices of goods traded in bulk at the wholesale level (i.e., between traders/manufacturers, not at the retail/consumer level). Key facts about WPI in India: Base year: 2011-12 (revised from the earlier 2004-05 base year); Coverage: WPI covers 697 commodities in three major groups — Primary Articles (22.62%), Fuel & Power (13.15%), and Manufactured Products (64.23%); WPI is calculated and published monthly by the Office of the Economic Adviser, Ministry of Commerce and Industry; WPI captures price changes at the primary/wholesale market level, before retail markup; WPI in India does NOT include services (only goods/commodities); WPI is often used as a deflator in national accounts and as a leading indicator of inflation in the manufacturing sector.
Option (a) Gross Domestic Product Deflator — Incorrect: The GDP Deflator measures the ratio of nominal GDP to real GDP, indicating the overall price level change in the entire economy (goods and services); it is broader than WPI and is not specifically called a 'wholesale prices' index.
Option (b) Consumer Price Index — Incorrect: The Consumer Price Index (CPI) measures the change in prices of a basket of goods and services at the RETAIL level — i.e., what consumers pay; it is the opposite of wholesale prices and is used to measure consumer inflation. The candidate incorrectly selected this option.
Option (c) Index of Industrial Production — Incorrect: The Index of Industrial Production (IIP) measures the VOLUME/QUANTITY of industrial output (manufacturing, mining, electricity), not prices; it indicates how much has been produced, not how much it costs at the wholesale level.

Monetary Policyis formulated by theReserve Bank of India (RBI).
It controls money supply and interest rates in the economy.
Primary Objective:To maintainprice stabilitywhile keeping in mind the objective of growth.
Price stability means controlling inflation and ensuring stable purchasing power.
Other objectives include economic growth and financial stability, but price stability is the primary goal.
Answer: Option 2 → To maintain price stability

Topic:Fiscal Policy & Government Spending
Question:Limitation of increasing government expenditure to promote economic growth
Key Concept:Expansionary fiscal policy increases aggregate demand
Main Limitation:Excess government spending → Higher demand → Demand-pull inflation
When government spending exceeds productive capacity, prices rise rapidly
Other options incorrect:
Social capital development & foreign trade are positive outcomes
Stagflation = inflation + stagnation (not typical result of spending increase)
Answer: Option 3 →

Topic: Monetary Policy Framework - India
The Government of India, in consultation with RBI, sets the inflation target under the Monetary Policy Committee (MPC) framework.
Current Target (extended until April 2026):
• Inflation Target:4%
• Tolerance Band:±2%
• Upper Limit: 6%
• Lower Limit: 2%
This framework was first notified in August 2016 and has been renewed periodically.
Answer: Option 2 → 4% with a tolerance of ±2%

Correct Answer: Option 3 – Inflation
When aggregate demand (AD) grows faster than aggregate supply (AS), there is excess demand in the economy. Buyers are competing for a limited supply of goods and services, which pushes prices upward. This results in Inflation — a general rise in the price level. This is also called demand-pull inflation.
Why other options are wrong:
Option 1 (Deflation): Deflation is a fall in the general price level, occurring when demand falls below supply — opposite of the scenario described.
Option 2 (Stagflation): Stagflation occurs when there is both high inflation AND high unemployment/economic stagnation simultaneously, typically due to supply shocks — not simply because AD exceeds AS.
Option 4 (Depression): A depression is a severe, prolonged economic downturn with massive unemployment and falling prices. It occurs when demand collapses, not when demand exceeds supply.

Correct Answer: Option 1 – A-2, B-3, C-1
GDP Deflator (A) → Broad measure of price level changes (2):
The GDP Deflator measures the price changes of ALL goods and services included in GDP — not just a basket of consumer goods like CPI. It is the broadest measure of price level changes in the economy. Formula: GDP Deflator = (Nominal GDP / Real GDP) × 100.
Inflation (B) → Rise in general price levels (3):
Inflation is defined as a sustained rise in the general price level of goods and services in an economy over a period of time.
Demand Forecasting (C) → Anticipatory tool for planning (1):
Demand forecasting is the process of estimating future demand for a product or service. It is an anticipatory (forward-looking) tool used by businesses and governments for production planning, resource allocation, and policy decisions.
Why other options are wrong:
Options 2, 3, 4: All have incorrect pairings.

The correct answer is (b) A general increase in the price of goods and services.
Inflation is defined as the sustained, general increase in the price level of goods and services in an economy over a period of time. When inflation occurs, each unit of currency buys fewer goods and services, reducing purchasing power. It is measured by indices like CPI (Consumer Price Index) and WPI (Wholesale Price Index).
(a) A decrease in the price of goods: This describes deflation, which is the opposite of inflation.
(c) A government's budget being in surplus: A budget surplus occurs when revenue exceeds expenditure; this is a fiscal concept unrelated to inflation's definition.
(d) A period of high employment: High employment is a macroeconomic goal; while it can sometimes correlate with inflation, it is not the definition of inflation.

Deflation refers to a sustained decrease in the general price level of goods and services over time. It is the opposite of inflation and can lead to reduced consumer spending and economic slowdown.
(a) Incorrect: Inflation is a sustained increase in the general price level.
(c) Incorrect: Stagflation refers to a combination of high inflation, high unemployment, and stagnant economic growth.
(d) Incorrect: Disinflation refers to a slowing in the rate of inflation, not an actual decrease in price levels.

Hyperinflation refers to an extremely high and typically accelerating rate of inflation, where the general price level increases rapidly and the currency loses its value very quickly. Classic examples include Zimbabwe (2000s) and Germany in the 1920s (Weimar Republic).
(a) Incorrect: Deflation is a decrease in the general price level; it is the opposite of inflation, not a very high rate of inflation.
(b) Incorrect: Disinflation refers to a slowing in the rate of inflation (prices still rising but more slowly); it is not the same as very high inflation.
(c) Incorrect: Stagflation refers to the simultaneous occurrence of stagnant economic growth and high inflation; it does not specifically mean an extremely high rate of inflation where money loses value very quickly.

Correct Answer: When the general price level rises, the value of money tends to fall.
This is a fundamental macroeconomic principle: Inflation (rise in general price level) reduces the purchasing power of money. When prices rise, each unit of currency buys fewer goods and services — so the value/purchasing power of money falls. This is the inverse relationship between price level and value of money.
Option 1: Incorrect. GDP does NOT include earnings sent home by overseas workers (those are remittances and part of GNP). GDP measures output produced within the country's borders.
Option 3: Incorrect. A balanced budget means government revenue = government expenditure, not exports vs imports (that's trade balance).
Option 4: Incorrect. Central banks control inflation primarily through monetary policy tools (interest rates, CRR, repo rate) — NOT income tax rates (that's fiscal policy by the government).

Correct Answer: Firm not be able to produce higher quantities that are being demanded at ongoing prices.
When the government increases spending or cuts taxes, aggregate demand in the economy rises. However, firms cannot immediately produce higher quantities at ongoing (existing) prices due to capacity constraints, supply bottlenecks, and resource limitations. This excess demand over supply pushes prices upward - a phenomenon known as demand-pull inflation. This is a key concept in Keynesian economics.
Why other options are wrong:
- Aggregate demand falls rapidly: The opposite is true; government spending increases aggregate demand.
- Wage increases unprecedentedly: While wages may rise over time, this is a cost-push factor; the direct reason for price rise here is demand-supply mismatch.
- Firm exports produce to foreign destinations: Exports may reduce domestic supply but this is not the primary reason for price rise from government spending.

The Technical Review Committee on the Wholesale Price Index (WPI), chaired by economist Abhijit Sen, submitted its report in 2008. The committee recommended revising the WPI series and adopting 2004-05 as the new base year. The other years — 2004, 2010, and 2006 — do not correspond to the submission of this committee's report.

Correct Answer: 2008
The Working Group on Revision of the Wholesale Price Index (WPI) was chaired by Prof. Abhijit Sen, a member of the Planning Commission. The committee submitted its report in 2008, leading to the revision of the WPI series (base year changed to 2004-05).
Why other options are wrong:
- 2004: The committee was not reporting in 2004.
- 2010: The revised WPI series was released later, but the committee report was in 2008.
- 2006: Not the correct year of submission.

Correct Answer: Option 3 – Stagflation
Stagflation is the economic condition characterized by simultaneously high inflation, stagnant (slow or zero) economic growth, and often high unemployment. The term was coined during the 1970s oil crisis when many economies experienced this unusual combination (normally inflation and unemployment move in opposite directions per the Phillips Curve).
Option 1 (Recession): A period of significant economic decline (negative GDP growth); not necessarily combined with high inflation.
Option 2 (Hyperinflation): Extremely rapid and out-of-control inflation (typically >50% per month); does not specifically describe the combination with stagnation.
Option 4 (Deflation): A general decrease in the price level; opposite of inflation.

Correct Answer: Option 1 – Consumer Price Index (CPI)
The Consumer Price Index (CPI) measures changes in the price level of a fixed basket of goods and services purchased by households over time. It is the primary measure of inflation/deflation in an economy. In India, CPI is published monthly by the National Statistical Office (NSO) and covers items like food, beverages, clothing, housing, fuel, and miscellaneous goods. The RBI uses CPI as the benchmark for its inflation targeting mandate (currently 4% ± 2%).
Option 2 (GDP): Gross Domestic Product measures the total monetary value of all goods and services produced in a country in a given period; it measures economic output, not price levels.
Option 3 (Gini Coefficient): Measures income/wealth inequality within a population (0 = perfect equality, 1 = perfect inequality); not a price level measure.
Option 4 (Balance of Payments): Records all economic transactions between a country and the rest of the world (current account, capital account); not a domestic price level measure.
