A Guide to ‘Greedflation’
Why Read This
What Makes This Article Worth Your Time
Summary
What This Article Is About
Financial Times columnist Tim Harford examines greedflation — the popular theory that corporations deliberately exploit periods of high inflation to inflate their profit margins beyond what rising costs justify. He argues that while companies do maximise profits, the greedflation explanation is logically flawed: it cannot account for why corporate “greed” would suddenly intensify during inflation spikes and then subside. Harford surveys academic models by economists like Paul Scanlon (Trinity College Dublin) and Isabella Weber and Evan Wasner (University of Massachusetts Amherst), who propose mechanisms involving inflationary camouflage and supply-shock signalling.
However, Harford pivots to empirical evidence — particularly a University of Warwick study by Johannes Brinkmann and Nikhil Datta on UK petrol prices during the 2022 oil shock — which shows the opposite of greedflation: retailers compressed their margins when wholesale costs rose sharply. This is explained by the “rocket and feather” pricing phenomenon: prices surge quickly but fall slowly, meaning companies quietly make their money during the calm, low-inflation periods when consumers are least vigilant. Harford concludes that regardless of which theory is correct, consumers and competition authorities should remain most alert precisely when inflation is low and nobody is talking about greedflation.
Key Points
Main Takeaways
Corporate Greed Alone Falls Short
Blaming inflation purely on corporate greed fails because it cannot explain why companies would suddenly become greedier during inflationary periods and not at other times.
Inflation Provides Pricing Camouflage
Paul Scanlon’s model suggests firms exploit high-inflation confusion to raise prices beyond cost increases, as consumers struggle to distinguish genuine price shifts from profiteering.
Evidence Points the Other Way
Brinkmann and Datta’s Warwick study found UK diesel retailers compressed margins in 2022 — the opposite of greedflation — because consumers searched intensely when prices rose sharply.
Rocket and Feather Pricing
Retail prices rise quickly like a rocket when costs spike but fall slowly like a feather — companies extract profit margins during the quiet downward drift, not during the surge.
Consumer Vigilance Is Misaligned
Consumers search hardest for better prices when prices are rising — precisely when there is least variation between retailers — and relax when prices fall, missing the real savings opportunity.
Low Inflation, Highest Guard Needed
Harford’s core warning: the moment greedflation disappears from public debate is exactly when consumers and competition authorities should be most alert to corporate pricing behaviour.

Article Analysis
Breaking Down the Elements
Main Idea
Greedflation Is Real — But Probably Works in Reverse
Harford’s central argument is that while corporate profit-seeking does influence pricing, the popular greedflation narrative — that companies exploit inflation peaks — gets the timing backwards. The empirical evidence suggests companies are more likely to quietly widen margins during low-inflation periods, when consumers are complacent, than during high-inflation spikes, when consumers scrutinise every price.
Purpose
To Educate Consumers and Reframe the Debate
Harford writes primarily to inform and gently challenge popular misconceptions. Originally published in the Financial Times, the piece aims to raise consumer and policy awareness — arguing not that greedflation is a myth, but that worrying about it only during high-inflation episodes misses the periods when corporate pricing behaviour most demands scrutiny.
Structure
Populist Hook → Theoretical → Empirical → Prescriptive
The article opens by questioning the intuitive appeal of greedflation, then surveys competing academic theories (Scanlon’s camouflage model; Weber and Wasner’s supply-shock signalling). It pivots to contradicting empirical evidence — the UK fuel market study and Peltzman’s cross-sector survey — before closing with a practical, policy-oriented recommendation for consumers and regulators alike.
Tone
Wry, Measured & Intellectually Curious
Harford’s voice is characteristic Financial Times — urbane, lightly ironic, and intellectually honest. He acknowledges the appeal of greedflation narratives (“it’s nice to have someone to blame”) before dismantling them, which keeps the tone fair-minded rather than polemical. The article is ultimately cautionary and pragmatic, ending with an actionable message rather than a partisan conclusion.

Made worse or more severe; used when an existing problem is intensified by an additional factor beyond its original cause.
“So is there a coherent case that inflation spikes are somehow exacerbated by corporate profiteering?”
In an economic context, the use of a broadly confused or inflationary environment as cover to disguise or justify price increases that exceed genuine cost pressures.
“…corporations use more general inflation as camouflage, raising prices more than they need to because consumers are already expecting trouble…”
Showing a smug or uncritical satisfaction with one’s situation; in a consumer context, failing to remain alert or search for better options because conditions seem favourable.
“…customers are militant when prices are rising sharply and complacent when prices are subdued.”
Confused about one’s position, direction, or situation; here describing the state of consumers and businesses who cannot distinguish relative price changes from overall inflation signals.
“One of the costs of inflation has always been that it disorients everyone, making it harder to figure out whether a change in a price…is a shift in relative prices or part of some general inflationary surge.”
Seeming reasonable or probable; an argument or explanation that could believably be true based on available evidence, even if not yet conclusively proven.
“But the opposite seems equally plausible: that customers are militant when prices are rising sharply and complacent when prices are subdued.”
The open area in front of a petrol/fuel station where vehicles pull up to refuel; used in British English as a synonym for a petrol station retail site.
“…there was more variability from forecourt to forecourt and a higher return to shopping around, but most customers did not bother…”

FAQ
Frequently Asked Questions
“Rocket and feather” describes the asymmetric way retail fuel prices respond to oil price movements: they shoot up rapidly like a rocket when wholesale costs rise, but drift down slowly like a feather when costs fall. Harford draws on research by Brinkmann and Datta, and earlier work by Matthew Lewis and Howard Marvel, to show this is a well-documented pattern — and that retailers quietly earn their margins during the slow descent, not the rapid ascent.
The popular view treats greedflation as straightforward opportunism — firms raising prices simply because they can. Scanlon’s academic model, published as “A model of greedflation,” provides a more precise mechanism: inflation creates widespread confusion about whether price changes reflect real cost shifts or general price rises. Firms exploit this disorientation as camouflage, raising prices beyond what cost increases alone would justify, because consumers cannot easily distinguish legitimate increases from profit-grabbing ones.
Isabella Weber and Evan Wasner of the University of Massachusetts Amherst proposed that supply shocks — such as a sudden spike in oil prices — can act as a publicly visible signal that allows rival firms to raise prices simultaneously without needing to coordinate secretly or risk legal penalties for collusion. When one sector’s costs rise visibly, it provides a legitimate-seeming pretext for firms across the economy to widen their own margins under the cover of a general cost-push environment.

He is the author of several acclaimed books that make economics accessible to general audiences, including How to Make the World Add Up. His credibility on greedflation comes from his ability to synthesise peer-reviewed academic research (Scanlon, Weber and Wasner, Brinkmann and Datta, Peltzman, Lewis and Marvel) with clear, evidence-driven reasoning aimed at non-specialist readers.
