What it's about

Tim Harford argues that everyday transactions—a cup of coffee, a used car, a house price, a trip to the supermarket—are governed by the same economic forces that shape nations: scarcity, bargaining power, information asymmetry, and externalities. Writing for readers with no economics training, he shows that prices are not arbitrary but encode information about costs, demand, and market structure, and that understanding this makes visible the hidden logic behind inequality, pollution, globalization, and market failure.

Who it's for

What’s inside

1
The Price of Coffee and the Power of Scarcity
Prices near high-traffic locations are high not because of greed but because scarce, immovable land forces sellers to extract nearly all the surplus a captive customer is willing to pay.
1 min
2
Price Discrimination and the Art of Charging Different People Differently
Companies profit most not by setting one 'fair' price but by sorting customers into groups and charging each what they individually will bear.
1 min
3
When Markets Fail: Externalities and the True Cost of Things
Markets systematically misprice goods when the costs or benefits of a transaction spill onto people who are not party to it, and only correcting for this spillover produces genuinely efficient prices.

4
The Economics of Information: Why Used Cars Are a Trap
When sellers know more about a good's quality than buyers do, markets can collapse into a race to the bottom where only bad products remain for sale.
1 min
5
Game Theory and the Auctioning of Everything
When many bidders compete for a scarce, valuable resource, well-designed auctions can extract nearly the full value for the seller, revealing how much money was previously left on the table by ad hoc pricing.
1 min
6
Why Poor Countries Stay Poor: Institutions Over Resources
National poverty is caused less by a lack of natural resources or hard work and more by weak institutions—property rights, contract enforcement, and low corruption—that markets need to function.
1 min
7
Free Trade, Globalization, and Who Really Gains
Free trade generally raises total wealth by letting countries specialize in what they do relatively well, but the gains are distributed unevenly and the losers are real, not hypothetical.
1 min
8
Health Care, Insurance, and the Limits of Market Logic
Health care markets resist the normal efficiency-producing forces of competition because information asymmetry, the difficulty of avoiding subsidizing bad choices, and the impossibility of comparison shopping while in a medical emergency all break the standard model.
