Inflation — Set 1

Correct Answer: C. Consumer Price Index (CPI)

• **Consumer Price Index (CPI)** = India's primary inflation benchmark for monetary policy, adopted by the RBI in 2014. • **2014** — RBI officially shifted from WPI to CPI following the Urjit Patel Committee recommendations. • 💡 Wrong-option analysis: [Option A] GDP Deflator is calculated by NSO and covers total economy, not used by RBI for policy; [Option B] WPI measures wholesale goods only and excludes services; [Option D] PPI measures seller-side price changes and is not India's official inflation benchmark.

Correct Answer: C. Demand-Pull Inflation

• **Demand-Pull Inflation** = inflation triggered when total demand outpaces total productive capacity, described as too much money chasing too few goods. • **High employment** — rapidly growing economies with high employment are most vulnerable because wage income boosts consumer spending beyond supply capacity. • 💡 Wrong-option analysis: [Option A] Cost-Push Inflation arises from rising production costs, not excess demand; [Option B] Stagflation is high inflation combined with stagnant growth; [Option D] Hyperinflation is extreme price surge exceeding 50% per month, a severity level, not a cause-based category.

Correct Answer: C. Stagflation

• **Stagflation** = a simultaneous occurrence of stagnant economic growth, high inflation, and persistently high unemployment in one economy. • **1970s oil shock** — the classic global example when OPEC's oil embargo triggered cost-push inflation while growth collapsed, proving the stagflation paradox. • 💡 Wrong-option analysis: [Option A] Reflation is a deliberate policy to stimulate growth after deflation, opposite scenario; [Option B] Disinflation is only a slowdown in the rate of inflation, prices still rise; [Option D] Deflation is a fall in the general price level, opposite of inflation.

Correct Answer: A. 2012

• **Base Year 2012** = the reference year used for calculating India's Consumer Price Index (Combined), against which all current prices are compared. • **Ministry of Statistics and Programme Implementation** — periodically revises the base year to reflect changing household consumption patterns across India. • 💡 Wrong-option analysis: [Option B] 2010 is not the official CPI base year; [Option C] 2004-05 was used as the base year for older WPI series, not CPI; [Option D] 2011-12 is the base year used for GDP calculations, not for CPI.

Correct Answer: C. Office of Economic Adviser

• **Office of the Economic Adviser (OEA)** = the body under the Ministry of Commerce and Industry that releases India's WPI data every month. • **WPI excludes services** — unlike CPI, WPI covers only goods traded in bulk at wholesale level, making it a producer-focused price index. • 💡 Wrong-option analysis: [Option A] RBI uses and monitors inflation data but does not publish WPI; [Option B] Ministry of Finance frames fiscal policy but does not publish WPI; [Option D] NITI Aayog is a policy think-tank and does not compile price indices.

Correct Answer: D. Inflation excluding food and fuel items

• **Core Inflation** = the measure of price-level change in goods and services after removing volatile food and energy components from the basket. • **Long-term trend** — by stripping out seasonally volatile items, Core Inflation reveals the underlying persistent inflation that guides central bank policy. • 💡 Wrong-option analysis: [Option A] Including food and fuel gives Headline Inflation, not Core; [Option B] Inflation at wholesale level is WPI, not a definition of Core; [Option C] Recession-period inflation relates to Stagflation or disinflation, not Core Inflation.

Correct Answer: C. Extremely rapid and out-of-control inflation

• **Hyperinflation** = an extreme, uncontrolled inflation scenario where prices rise so rapidly that the currency loses almost all its value in a very short time. • **50% per month threshold** — economists commonly define hyperinflation as monthly price increases exceeding 50%, as seen in 1920s Germany and 2000s Zimbabwe. • 💡 Wrong-option analysis: [Option A] Negative inflation rate is Deflation, not Hyperinflation; [Option B] Inflation of 10-20% is Galloping or Running Inflation; [Option D] Inflation of 2-3% is Creeping Inflation, the mildest form.

Correct Answer: D. Debtors (Borrowers)

• **Debtors (Borrowers)** = the group that benefits from unexpected inflation because they repay loans using money whose real purchasing power has declined. • **Real debt burden falls** — if inflation is 8% but interest rate is 6%, the real interest rate turns negative, meaning borrowers effectively gain purchasing power over lenders. • 💡 Wrong-option analysis: [Option A] Fixed Income Earners lose because their income stays constant while prices rise; [Option B] Creditors lose because the money repaid to them buys less than what they lent; [Option C] Pensioners suffer like fixed income earners since pension amounts are typically fixed.

Correct Answer: C. Phillips Curve

• **Phillips Curve** = a curve showing the short-run inverse trade-off between inflation and unemployment — lower unemployment tends to come with higher inflation. • **A.W. Phillips, 1958** — the British economist first documented this relationship using UK wage and unemployment data spanning nearly a century. • 💡 Wrong-option analysis: [Option A] Lorenz Curve measures income or wealth inequality distribution; [Option B] Kuznets Curve shows the inverted-U relationship between income and inequality; [Option D] Laffer Curve shows the relationship between tax rates and government revenue.

Correct Answer: C. Deflation

• **Deflation** = a sustained fall in the general price level of goods and services, meaning the inflation rate turns negative. • **Dangerous downward spiral** — deflation causes consumers to delay spending expecting further price drops, which reduces production, causes job losses, and deepens recession. • 💡 Wrong-option analysis: [Option A] Reflation is a policy to boost prices and revive economy after deflation; [Option B] Disinflation is a reduction in the rate of inflation — prices still rise but more slowly; [Option D] Skewflation is a price rise concentrated in only one or few commodities, not a general price fall.
