On Monday, 12 October, the National Statistics Office (NSO) under the Ministry of Statistics and Programme Implementation released provisional data: retail inflation, measured by the Consumer Price Index (CPI), rose to 5.54% in September from 4.83% in August. It is the highest in the new CPI series (base year 2024) and the fourth month in a row above the RBI's 4% target. Food inflation jumped from 5.97% to 7.74%. Onion was 108.09% dearer than a year earlier; ginger, garlic and lemon also rose sharply, while potato (−11.50%) and tomato (−8.62%) were cheaper. Rural inflation was 6.08% and urban 4.88%. Core inflation, which leaves out food and fuel, rose from 4.1% to 4.3%, and 11 of the 12 categories of the basket accelerated. Of the 71 basis points by which inflation rose, 62 came from food (ICRA).
Two other facts sit behind the number. First, the GST was cut across the board from 22 September 2025, so prices a year ago were unusually low: a base effect that makes this year's rate look higher, and will grow in October. Second, cooking gas has become costlier with Brent crude above $100 and war in West Asia, and the price of a meal in a restaurant ("restaurants and cafés") rose 9.39% against 2.73% in February.
A week earlier, on 7 October, the Monetary Policy Committee had raised the repo rate by 25 basis points to 5.50%, its first hike since February 2023. Economists at ICRA, India Ratings and HDFC Bank now expect inflation of about 6% in October.
On the same Monday, in Stockholm, the Economics Nobel went to Robert E. Hall and Michael Woodford "for microeconomic foundations of macroeconomic stabilisation". Woodford showed that firms set prices looking ahead, so what people expect about future interest rates and prices shapes inflation today. That is why a central bank raises rates even when the shock began in an onion field: not to grow onions, but to stop a food shock from becoming everyone's expected inflation.
One number, many questions: what kind of inflation is this, what is causing it, who is hurt, and which tool fits which cause? That is today's concept.

URGENT · FOR DECISION
To: District Collector, a drought-hit district
Subject: Retail onion prices doubled in a year; press alleges hoarding; three proposals for immediate orders
The September price data came out yesterday. Onion is 108% dearer than a year ago, and rural prices are rising faster than urban ones. The local papers say traders are hoarding. Three notes are on your table this Tuesday morning.
(1) The district supply officer proposes "surprise raids on every onion wholesaler and commission agent from tomorrow", a written order that no onion may leave the district "until prices normalise", and a notice fixing the retail price of onion in all markets.
(2) The warden of a government residential school for tribal girls writes that the per-child food allowance, fixed in rupees at the start of the year, "no longer buys the menu". She proposes to cut dal to four days a week and drop vegetables at dinner until March, "as there is no other way to stay within budget".
(3) The manager of the district cooperative marketing society says the Centre's buffer onions can be sold through ration shops and cooperative outlets at a lower price, but asks who will meet the cost of transport and handling, and whether "it is worth the trouble for a few weeks".
A delegation of farmers is also coming at noon: they say high prices are the first good news they have had in two seasons. Before evening, write one page: what you order on each note, and why. You have 24 hours.

2The story
3The skeleton: types, causes, effects, and who acts
3a. The idea, in plain words
Inflation is a sustained rise in the general level of prices, so that each rupee buys less. Three words in that sentence matter. Sustained: a one-day jump is not inflation. General: when onions alone get dearer while potatoes get cheaper, that is first a change in relative prices; it becomes inflation when the rise spreads across the basket. Level: inflation is the rate of change of the price level, usually measured as the change over the same month a year earlier.
It is measured with a price index: the cost of a fixed basket of goods and services, compared with a base year set at 100. India's main indices are the CPI (compiled by the NSO; the new series has base 2024=100 and 12 divisions), the Wholesale Price Index (WPI, compiled by the Office of the Economic Adviser in the Department for Promotion of Industry and Internal Trade, covering goods only, not services), and the CPI for Industrial Workers and for Agricultural and Rural Labourers (compiled by the Labour Bureau, used to revise dearness allowance and some wages). The GDP deflator covers the whole economy. Each is a separate class (economy-010).
Related words: deflation is a fall in the price level (inflation below zero); disinflation is a fall in the rate of inflation while prices still rise (say 6% to 4%); reflation is a deliberate push to raise prices and output after a slump; stagflation is high inflation with stagnant output and high unemployment, as in the 1970s.
Rule of thumb: inflation falling does not mean prices falling. It means they are rising more slowly.

Rule of thumb: inflation falling does not mean prices falling. It means they are rising more slowly.
3b. Types by cause
| Type | What happens, and an example from today |
|---|---|
| Demand-pull | Too much money chasing too few goods: spending (by households, firms or government) grows faster than what the economy can produce, so sellers can raise prices. Easy credit, large fiscal deficits and rapid money growth feed it. It is what a repo rate hike works on most directly. |
| Cost-push | The cost of producing rises (fuel, raw materials, wages, taxes), and producers pass it on. Today: costlier cooking gas lifting restaurant meals and transport fares. When the cost comes from abroad (crude oil, a weaker rupee raising import prices) it is also called imported inflation. |
| Supply shock (a kind of cost-push) | Output falls suddenly: a failed monsoon, a pest, a war that blocks a sea route. Today: old onion stocks run out before the new crop arrives, after a weak monsoon. Prices of that item jump though demand has not changed. |
| Built-in (wage–price spiral) | Workers expect prices to rise and ask for higher wages; firms raise prices to cover wages; workers ask again. Expectations keep the fire burning after the first spark has gone. This is the "second-round effect" the MPC watches. |
| Structural | Inflation that comes from bottlenecks in the economy itself: too little storage and cold chains, fragmented markets, low farm productivity, poor transport. Many Indian economists have long argued that much of India's food inflation is of this kind; a rate hike cannot remove it. |
3c. Types by speed (no official cut-offs; textbooks differ)
| Type | What it looks like |
|---|---|
| Creeping (mild) | Low and steady, a few per cent a year. Most economists think some of it is healthy: it lets real wages and prices adjust and keeps the economy away from deflation. |
| Walking or trotting | Higher single digits; people begin to notice, to bargain for wage rises and to buy early. |
| Galloping (running) | Double or triple digits a year; money loses value fast, savings move to gold, land and foreign currency. |
| Hyperinflation | Prices rise so fast that money stops working: Germany in 1923 and Zimbabwe in 2008 are the textbook cases. It is almost always caused by a government printing money to pay its bills. |
3d. Which number? Headline, core, food, and the base effect
| Measure | What it tells you |
|---|---|
| Headline inflation | The whole CPI basket: 5.54% in September. It is what people live with, and what India's legal target is set on. |
| Core inflation | Headline minus food and fuel, whose prices swing with weather and oil: 4.3% in September. It shows the persistent trend that monetary policy can influence. |
| Food inflation (CFPI) | The Consumer Food Price Index: 7.74% in September. Food takes a larger share of a poorer, rural family's spending, so the same food shock hurts it more. |
| Base effect | Because inflation compares with a year earlier, an unusually low price last year (here, after the GST cut of 22 September 2025) raises this year's rate even if prices barely move this month. A high base does the opposite. |
3e. Effects: who loses, who gains
| Who | Effect of unexpected inflation |
|---|---|
| Net buyers of food: landless labourers, the urban poor | Lose most. They spend a large share on food and have no stock or assets that rise in price. This is why economists call inflation a "tax on the poor". |
| People on fixed money incomes: pensioners without indexation, workers on fixed wages, schemes with fixed rupee norms | Lose: the same rupees buy less (the warden's problem in the file). |
| Savers and lenders | Lose if the interest rate is below inflation. The real interest rate is roughly the nominal rate minus inflation (Irving Fisher's relation). |
| Borrowers, including the government | Gain: the real burden of a fixed rupee debt falls. |
| Farmers with a surplus to sell | May gain on that crop, but not if a drought leaves little to sell, and they also buy inputs and food. |
| Exporters and the economy | Higher domestic inflation makes exports less competitive unless the rupee weakens. Uncertain prices make long-term contracts and investment harder; firms spend effort repricing ("menu costs"). |
3f. The legal and institutional skeleton
| Provision or body | What it does for this concept |
|---|---|
| RBI Act, 1934, Section 45ZA | The Centre, in consultation with the RBI, sets the inflation target once every five years: 4% CPI inflation within a 2–6% band, retained in March 2026 for 2026–31. |
| Section 45ZB | Creates the six-member Monetary Policy Committee: the Governor (chair, with a casting vote), the Deputy Governor in charge of monetary policy, one RBI officer nominated by the Central Board, and three outside members appointed by the Centre for four years. |
| Section 45ZN | If the RBI fails to meet the target (defined as inflation outside the band for three consecutive quarters), it must report to the Centre the reasons, the remedial action and the time it expects to take. |
| NSO, MoSPI | Compiles and releases the CPI every month (the October print is due on 12 November 2026), from prices collected in 1,407 urban markets (including online) and 1,465 villages. |
| Essential Commodities Act, 1955 | Lets the Centre (and States under delegated powers) regulate production, supply, distribution and stocks of essential commodities, including stock limits in times of sharp price rise. District officers enforce notified limits. |
| Price Stabilisation Fund (Department of Consumer Affairs) | Funds buffer stocks of onions and pulses, released into the market when prices rise. |
| GST Council (Article 279A) | Tax rates feed directly into prices; the 2025 cut lowered prices then and creates today's base effect. |
Rule of thumb: diagnose before you prescribe. Demand-pull and second-round effects: the repo rate. Supply shocks: buffers, trade, storage and logistics. Structural causes: investment and reform. Expectations: credible targets and clear communication.
4The fine print — what separates a topper from the rest
1. A relative price shock is not yet inflation. In September onion rose 108% while potato fell 11.5% and tomato 8.6%. If only onion had risen, the right response would be onion policy, not monetary policy. What turns it into inflation is spread: core up from 4.1% to 4.3%, 11 of 12 categories accelerating, restaurant prices up on costlier gas. The MPC "looks through" the first round and acts on the second.
2. The base effect can mislead in both directions. A 5.54% print partly reflects a low base from the 2025 GST cut. When the base is high, inflation can look low though prices are still rising. Read the month-on-month change and the trend along with the year-on-year rate.
3. India targets headline CPI, not core, and that was a choice. The Urjit Patel Committee (January 2014) recommended headline CPI (Combined) as the nominal anchor, partly because food is a large part of what Indians buy and food inflation shapes what households expect. The cost: the MPC is judged on a number that includes onions it cannot control. The "flexible" in flexible inflation targeting, the 2–6% band, is the answer to that cost (economy-011).
4. Expectations are the hinge. If people believe 4% will hold, a food shock fades; if they believe prices will keep rising, workers ask for more, firms reprice early, and the shock becomes built-in inflation. This is the work for which Woodford shared the 2026 prize, and the reason the RBI explains its likely future path ("forward guidance") and conducts household surveys of inflation expectations.
5. Inflation is a regressive tax. Rural inflation (6.08%) is above urban (4.88%), and rural food inflation (8.06%) above urban (7.18%), because food weighs more in a village family's spending. Holding cash, which the poor do more, loses value. The rich hold assets that often rise with prices. So "moderate" inflation on average can be severe inflation for the poorest household.
6. The target is 4%, not 0%, for good reasons. Some inflation lets relative prices and real wages adjust without nominal cuts, gives the central bank room to bring real interest rates below zero in a slump, and keeps the economy away from deflation, which makes people postpone spending and makes debts heavier. Japan's long years of falling prices from the late 1990s are the usual warning.
7. High prices help some farmers and hurt many. A farmer with onions to sell gains; a farmer whose crop failed in the drought, a landless labourer, and a small farmer who buys food for part of the year all lose. Policy that only chases low prices (export bans, raids) can also hurt farmers' incomes and next year's sowing. The balance is a Mains favourite.
8. Stagflation broke the old trade-off. The Phillips curve (A.W. Phillips, 1958) suggested that lower unemployment comes with higher inflation. The 1970s oil shocks brought high inflation and high unemployment together. Friedman and Phelps had argued that once people expect inflation, the trade-off disappears in the long run. The Nobel committee recalled that in that period Keynesian models "did not reduce unemployment, but led to uncontrolled inflation" (economy-012).
5How the idea grew
1911Irving Fisher's The Purchasing Power of Money states the quantity theory in the equation of exchange: money times its velocity equals prices times transactions. Too much money, other things equal, means higher prices.
1958A.W. Phillips publishes the inverse link between unemployment and the rate of change of money wages in Britain; the "Phillips curve" becomes a policy menu.
1967–68Edmund Phelps and Milton Friedman argue that the trade-off holds only while inflation is unexpected; once expected, it is built into wages and prices.
1973–79Two oil shocks. Much of the world, India included, suffers high inflation along with slow growth: stagflation. Cost-push and expectations enter every textbook.
1985The Chakravarty Committee recommends that the RBI follow monetary targeting (a target for money supply growth) with feedback.
1991The balance of payments crisis comes with double-digit inflation; reforms and the end of automatic monetisation of the deficit by ad hoc Treasury Bills (phased out by 1997) cut a major source of demand-pull inflation.
2008–2013A long spell of high, food-led inflation in India; inflation expectations rise and stay high.
2014 → 2015The Urjit Patel Committee (January 2014) recommends a CPI target of 4% with a band of ±2%. The Monetary Policy Framework Agreement between the Centre and the RBI follows in February 2015; the CPI with base 2012 starts in 2015.
2016The Finance Act, 2016 amends the RBI Act: Section 45ZA (target), 45ZB (MPC), 45ZN (accountability). The 4% target is notified for five years and the first MPC is constituted.
2022After the war in Ukraine, inflation stays above 6% for three straight quarters; in November 2022 the RBI sends its first report to the Centre under Section 45ZN explaining the failure.
2025 → early 2026The GST is cut across the board from 22 September 2025. A new CPI series with base year 2024 and 12 divisions begins in January 2026. In March 2026 the 4% (2–6%) target is retained for 2026–31.
October 2026On 7 October the MPC raises the repo rate to 5.50%; on 12 October September CPI inflation is 5.54% with onion up 108%, and the Economics Nobel goes to Hall and Woodford for the micro-foundations of stabilisation policy.
6One issue, six lenses
Polity & law
India made price stability a legal duty: Parliament wrote the target into the RBI Act and made the RBI answerable to the Centre when it misses. Food supply is regulated under the Essential Commodities Act, 1955, and trade in foodstuffs sits in the Concurrent List, so the Centre and the States both act.Carry: a target in law is a promise to citizens, with a duty to explain when it is broken.
Social justice
Inflation is felt most by those who own least: the rural poor, women who stretch the kitchen budget, daily-wage workers, pensioners without indexation. A 5.54% average hides a 6.08% village and a 108% onion.Carry: always ask "whose basket?" before you say "moderate inflation".
Governance
Every onion spike brings raids, export curbs and buffer releases that work for weeks. The slow fixes, storage, processing, market data, predictable trade rules, are the ones that prevent the next spike.Carry: firefighting is necessary; fire prevention is governance.
Economy
Diagnose the cause, then pick the tool. The repo rate cools demand and anchors expectations; it cannot add supply. Fiscal discipline keeps demand-pull in check; supply-side investment tackles structural inflation.Carry: one problem, many causes; one tool cannot do every job.
Ethics
Hoarding in scarcity is a moral wrong as well as an offence; so is a raid without evidence that frightens honest traders. The officer's virtue here is proportion: act on facts, protect the buyer without punishing the honest seller.Carry: in a crisis, fairness means evidence before force.
Citizen & nation
Stable prices are a public good: they protect the value of every citizen's savings and wages and the trust in the rupee itself. A country that imports most of its crude oil must also build resilience against prices set far away.Carry: the value of the rupee is a promise the whole nation keeps together.
7From paper to village — the implementation chain
How a price rise in a village market becomes a national number, and how the response travels back.
1
Field price collection: NSO staff price a fixed basket in 1,407 urban markets and 1,465 villages every month. Breaks if: the basket is outdated (hence the new 2024 base) or data has gaps; the RBI found state-wise CPI missing for some Covid months.
2
Release and reading: the CPI comes out on the 12th; analysts split it into food, core and base effects. Breaks if: the public reads only the headline and panics, or only the core and relaxes.
3
The MPC decides the repo rate and explains its view of the future. Breaks if: it acts too late, or overreacts to a shock that would have passed on its own.
4
Banks pass it on to loan and deposit rates; spending slows. Breaks if: transmission is slow; the effect on prices takes several quarters.
5
The Centre acts on supply: buffer releases from the Price Stabilisation Fund, trade measures, stock limits under the Essential Commodities Act. Breaks if: export curbs and stock limits come and go unpredictably, hurting farmers and next year's sowing.
6
The State and the district deliver: buffer onions through ration shops and cooperatives, enforcement of notified limits, published daily prices. Breaks if: buffer stock reaches cities but not villages, or raids replace evidence.
7
The household sees the price at the shop and forms its expectation of next month. Breaks if: no one explains what is happening; rumour sets expectations instead of facts.
8Who wants what
| Stakeholder | Wants | Fears | Their fair point |
|---|---|---|---|
| Landless labourer, urban poor | Cheap staples now | Skipping dal and vegetables; debt to the shopkeeper | They buy all their food; for them a food shock is a wage cut. |
| Onion farmer | A good price for a crop that finally sells well | Sudden export bans and stock limits that crash the price at harvest | Low prices for years left them in loss; policy should not punish them for one good season. |
| Wholesaler and trader | Freedom to store and move stock | Raids and blanket orders treating every trader as a hoarder | Storage between harvests is a real service; without it prices would swing even more. |
| Borrower (home, small business) | Low interest rates | A December rate hike | Rate hikes hurt borrowers without growing onions. |
| Saver and pensioner | Deposit rates above inflation; stable prices | Negative real returns eating their savings | They are told to save, and inflation quietly taxes that saving. |
| RBI and the MPC | Inflation back near 4%, credibility intact | Expectations rising, or a hike that hurts growth needlessly | The law holds them to a target; credibility lost is costly to regain. |
| The Centre and States | Prices down quickly, growth intact | Public anger; fiscal cost of subsidies and buffers | Supply measures and storage are theirs to deliver, not the RBI's. |
9The human side — EQ, citizen first, nation first
The people behind the file. In a village of the drought-hit district, a woman who works on others' fields buys onions by the piece, not the kilo, this month. In the residential school, a warden looks at the menu chart on the wall and the bill from the supplier and wonders which meal to cut. In the mandi, a commission agent who has stored onions honestly for twenty years reads in the paper that he is a hoarder. And the farmer who sold his onions at a loss two years ago comes to the Collector's office to say, please, do not take this season away from us.
An officer with emotional intelligence sees that everyone in this file is afraid, and that each fear is partly right. She does not reach for the loudest order. To the supply officer she says: "Show me the arrivals and the stocks first. If there is hoarding, the law gives us limits to enforce; if there is shortage, raids will make it worse." To the warden she says: "Do not cut the girls' dal. Potatoes and tomatoes are cheaper than last year; re-plan the vegetables, and I will take your case for a revised allowance to the State today." To the cooperative manager: "A few weeks is exactly when it matters. The district will find the handling cost." To the farmers: "Your price is not the enemy. We will move buffer stock to the poorest buyers, not crash the mandi."
And she asks herself one quiet question: if I bought my onions by the piece, what would I want the Collector to do this week?
Citizen first: the girl's plate, the labourer's kitchen, the farmer's fair price, the honest trader's name. Nation first: a country that keeps its prices stable and its poor fed through a drought keeps the trust of its people and the value of its currency.

11Your decision — back to the file
You are the District Collector. Choose your orders for today:
The note an officer would write
1. Nature of the rise. September CPI data show onion prices 108% above last year, with potato and tomato cheaper. Arrivals and stocks in the district's mandis to be compared with last year's within 48 hours to establish whether this is a shortage (old stocks running out after a weak monsoon) or hoarding.
2. Enforcement. Stock limits, if notified under the Essential Commodities Act, 1955, to be enforced on the basis of stock data, not blanket raids. No order restricting movement of onions out of the district; such orders shrink supply and hurt farmers.
3. Supply to the poorest. Buffer onions from the Price Stabilisation Fund to be sold through ration shops and cooperative outlets, with priority to villages and drought-hit blocks. Handling and transport costs to be met from district funds pending reimbursement.
4. Information. Daily mandi and retail prices to be published at the Collectorate and on the district website, to check rumour and profiteering.
5. Residential school. The proposed cut in dal and vegetables is not approved. The menu to be re-planned within nutrition norms using items whose prices have fallen. A proposal for revision of the per-child allowance to be sent to the State today, with the CPI data.
6. Farmers. The district will not take steps that crash the mandi price; buffer stock is aimed at the poorest buyers.
7. Submitted for information of the Divisional Commissioner.

Trap: "A fall in the rate of inflation from 6% to 4% means prices have fallen." — False; that is disinflation. Prices are still rising, only more slowly. Deflation means the price level itself falls.
Trap: "Core inflation includes food and fuel." — False; core excludes them because their prices are volatile. India's legal target is on headline CPI, not core.
Trap: "Unanticipated inflation benefits creditors and hurts debtors." — Reversed; it benefits debtors (the real value of debt falls) and hurts creditors and savers.
Trap: "The inflation target is fixed by the Monetary Policy Committee." — False; the Central Government fixes it under Section 45ZA in consultation with the RBI; the MPC sets the repo rate to achieve it.
Trap: "The WPI covers both goods and services." — False; the WPI covers goods only. Services are in the CPI.
Trap: "Creeping inflation is officially defined as below 3%." — There are no official thresholds for creeping, walking or galloping inflation; textbooks differ. Learn the idea, not a made-up cut-off.

"Not all inflation is alike, and not every inflation can be cured by the central bank." Discuss with reference to the causes of inflation in India. (15 marks, 250 words)Model approach
Directive — Discuss: explain the types and causes, match each to a tool, and conclude. Introduction: define inflation; September 2026 CPI 5.54%, food 7.74%, onion +108%. Body: (1) demand-pull: credit, fiscal deficit; the repo rate and fiscal discipline work; (2) cost-push and imported: cooking gas and crude oil; monetary policy only prevents second-round effects; (3) supply shocks and structural causes: a weak monsoon, poor storage; tools are buffers, trade policy, Operation Greens, storage; (4) built-in inflation and expectations: the MPC's flexible target and forward guidance (Woodford's work); core at 4.3% and 11 of 12 categories rising shows spread. Conclusion: diagnose before prescribing; the MPC guards expectations, governments fix supply. Diagram: a two-column chart, cause → tool.Mains practice 2 (GS3)
"Inflation is the cruellest tax on the poor." Examine, and suggest how public policy can protect vulnerable households. (10 marks, 150 words)Model approach
Directive — Examine: test the claim with evidence and qualify it. Introduction: inflation as an unlegislated tax on money incomes and cash. Body: rural 6.08% vs urban 4.88%; food's larger share in poorer budgets; fixed incomes and savings; the qualification: farmers with a surplus gain, borrowers gain. Protection: PDS and buffer releases, indexation of wages and pensions (CPI-IW, CPI-AL), revision of scheme norms, price stability as the best shield. Conclusion: low, stable inflation is pro-poor policy.13Check yourself
1. Distinguish deflation, disinflation and reflation.
Answer
Deflation is a fall in the general price level (negative inflation). Disinflation is a fall in the rate of inflation while prices still rise. Reflation is a deliberate policy push to raise prices and output after a slump.2. Onion rose 108% in September while potato fell 11.5%. Is that inflation? What made September's data a matter for the MPC?
Answer
Taken alone, it is a change in relative prices, a supply shock in one item. It matters for the MPC because the rise spread: core inflation rose from 4.1% to 4.3%, 11 of 12 categories accelerated and restaurant prices climbed on costlier gas, the second-round effects that monetary policy targets.3. What is the base effect, and why does it raise September's rate?
Answer
Because inflation compares prices with the same month a year earlier, an unusually low or high price then changes this year's rate. The GST cut from 22 September 2025 lowered prices a year ago, so the comparison base is low and the rate looks higher; the effect grows in October.4. Name the three sections of the RBI Act on the inflation framework and what each does.
Answer
Section 45ZA: the Centre, in consultation with the RBI, sets the target every five years (4%, band 2–6%). Section 45ZB: the six-member MPC. Section 45ZN: if the target is missed (outside the band for three consecutive quarters), the RBI reports reasons and remedies to the Centre.5. Who gains and who loses from unexpected inflation?
Answer
Debtors (including the government) gain; creditors, savers and people on fixed money incomes lose. Net buyers of food, such as landless labourers, lose most; producers with a surplus to sell may gain.6. Why can a repo rate hike not cure an onion shortage, and why does the MPC still raise rates?
Answer
The repo rate works on demand and cannot add supply. The MPC raises it to prevent the food shock from feeding expectations and spreading into wages and other prices (second-round effects), which would make inflation persistent.7. What did the 2026 Economics Nobel reward, and how is it linked to inflation policy?
Answer
Robert Hall and Michael Woodford were awarded "for microeconomic foundations of macroeconomic stabilisation". Woodford showed that firms set prices looking ahead, so expectations of future policy shape inflation; that is the basis of inflation targets and forward guidance.8. Why is the target 4% and not 0%?
Answer
Some inflation lets relative prices and real wages adjust, gives the central bank room to cut real interest rates in a slump, and keeps the economy away from deflation, which delays spending and makes debts heavier. India also chose a band (2–6%) to allow for supply shocks.“Know it, link it, feel it, decide it.”
