Summary
What This Article Is About
In this Financial Times column, economist Tim Harford argues that rising oil prices — painful as they are — serve a vital economic function. He compares price signals to nerve impulses: just as physical pain warns us to move away from danger, high prices tell consumers to cut back, prompt producers to save energy, and encourage innovation in alternative energy. Economist David Popp’s 2002 research on “induced innovation” showed that patent activity in solar energy closely tracked oil price spikes in the 1970s, illustrating how price signals drive technological change.
Harford’s deeper argument is a warning against government price controls. Using historical examples — President Nixon’s 1971 wage and price freeze, the UK’s 2022 energy bill cap under Liz Truss, and distorted chicken markets — he shows how suppressing prices removes the signals that guide smart economic behaviour. Instead of protecting people, price caps often create shortages, waste, and long-term fiscal damage, leaving economies worse off than if markets had been allowed to adjust naturally.
Key Points
Main Takeaways
Prices Are Pain Signals
High oil prices function like nerve impulses, alerting consumers and producers to adapt their behaviour and reduce dependence on a scarce resource.
Three Signals in One
An oil price spike simultaneously signals consumers to cut back, producers to save energy, and the market to shift toward substitute energy sources.
Innovation Follows Price
Economist David Popp’s research showed patent applications in solar energy surged from 10 in 1972 to over 300 annually in the late 1970s, tracking oil price rises closely.
Price Caps Backfire
Nixon’s 1971 price freeze and other historical controls created shortages, waste, and perverse outcomes — like farmers destroying newborn chicks because selling them meant a loss.
Economies Adapt Quickly
From Covid-19 to natural disasters, market participants rapidly find workarounds when prices are free to move, cushioning shocks that initially seem catastrophic.
Governments Often Get It Wrong
Political instincts lean toward numbing economic pain rather than letting signals work — a pattern Harford argues costs far more in the long run than the original shock.

Article Analysis
Breaking Down the Elements
Main Idea
Price Signals Are the Economy’s Nervous System
Harford’s central argument is that rising prices — however painful — are economically necessary signals. They coordinate millions of decisions across consumers, producers, and innovators simultaneously, without any central authority directing anyone. Suppressing these signals through price controls is like numbing pain instead of treating injury: it feels helpful in the short term but causes lasting damage.
Purpose
To Defend Market Prices Against Political Interference
Harford writes to persuade a general audience that government price controls — instinctively popular during crises — are economically counterproductive. He uses historical case studies and economic research to build a case that is accessible to non-specialists, urging readers to resist the political reflex to suppress price increases.
Structure
Explanatory → Evidential → Cautionary
The article opens by explaining how price signals work across three levels (consumer, producer, innovator), then draws on David Popp’s research to provide empirical backing. It pivots to historical cautionary tales — Nixon’s price freeze, UK energy caps — before closing with a memorable metaphor comparing prices to the nervous system and price controls to dangerous anaesthesia.
Tone
Conversational, Persuasive & Wry
Harford writes with the approachable wit typical of his FT columns — he opens by asking readers to “celebrate” an oil shock, uses vivid analogies like cardigans and nerve impulses, and ends with a deliberately provocative fentanyl metaphor. The tone is informal enough for a general reader but rigorous enough to carry an economic argument with real force.

A careful weighing of factors, costs, and benefits when making a decision — used figuratively here, not in the mathematical sense.
“Higher oil prices shift the calculus. Energy-saving measures that once seemed too difficult may now make sense.”
Producing a good or beneficial effect, especially as a warning or lesson — often used to describe an unpleasant experience that teaches something valuable.
“The 2008 banking crisis is a salutary counter-example.”
A substance that causes loss of sensation or pain — used metaphorically by Harford to describe price controls that mask economic distress without addressing it.
“The governmental instinct when voters are leaning on a hot stove is to inject a dose of anaesthetic rather than help them leap to safety.”
Well known for a negative or harmful reason; notorious — used to signal that the example about to be described is widely regarded as a serious mistake.
“The most infamous example is President Richard Nixon’s decision to freeze wages and prices in the US in the summer of 1971.”
A concept in economics describing how rising prices for a resource incentivise inventors and researchers to develop new technologies that reduce dependence on that resource.
“In 2002, the economist David Popp published a study of ‘induced innovation’, tracking the response by inventors to the oil shocks of the 1970s.”
Very severe or serious in its effects — used here to describe economic harm that initially appears devastating but is later cushioned by market adaptation.
“We have seen many examples of apparently grievous economic harm — from earthquakes to typhoons to regional wars to Covid-19 — in which the damage was cushioned.”

5 questions covering different RC question types
1According to Tim Harford, high oil prices are the root cause of the energy crisis and should be suppressed by governments to protect consumers.
2According to economist David Popp’s research, what happened to solar energy patent applications between 1972 and the late 1970s?
3Which of the following sentences best captures Harford’s central metaphor for how prices function in an economy?
4Based on the article, classify each of the following statements as True or False.
Nixon’s 1971 price freeze on gasoline contributed to long queues at petrol stations because artificially low prices encouraged excess consumption.
The UK’s 2022 energy bill cap under Liz Truss successfully reduced gas consumption and saved the government money.
Harford argues that price signals coordinate economic behaviour without requiring any central authority to direct individuals.
Select True or False for all three statements, then click “Check Answers”
5Based on Popp’s research findings, what can be inferred about what would likely happen to clean energy innovation if oil prices fell sharply and stayed low for several years?
FAQ
Frequently Asked Questions
Just as the nervous system transmits pain signals to alert the body to injury and trigger a protective response, prices transmit information about scarcity and cost across the entire economy. When a resource becomes scarce, its rising price simultaneously alerts consumers to reduce use, encourages producers to find efficiencies, and prompts innovators to develop alternatives — all without any central coordinator.
Induced innovation is the idea that rising prices for a resource directly incentivise inventors to develop technologies that reduce dependence on it. Harford cites Popp’s 2002 study because it provides concrete empirical evidence: solar energy patent applications tracked oil prices almost exactly in the 1970s, rising from 10 in 1972 to roughly 300 per year by the late 1970s, then falling again as oil prices dropped in the early 1980s.
The freeze created a cascade of unintended consequences. Chicken farmers faced capped selling prices while feed costs remained uncapped, making every chick a loss-making asset — leading farmers to destroy newly hatched chicks. Meanwhile, gasoline was abundant in rural areas near refineries but scarce in cities, because suppliers had no price incentive to cover the extra cost of urban delivery. These distortions show how price controls disrupt the coordination mechanism the entire economy depends on.
