Baumol's Cost Disease

mechanism

Labour-intensive services become relatively more expensive as productivity and wages rise elsewhere. The old repair economy was cheap partly because workers had fewer well-paid alternatives—not because repairing things was inherently more efficient.

The repairman of the past did not make fixing things cheap through some lost mastery. He was cheap because almost everyone was poor. Once that same worker can earn far more elsewhere, yesterday’s bargain-priced repair disappears.

The software salary reaches the repair shop

Some sectors can multiply output per worker; a labour-intensive repair still consumes roughly the repairer’s time. Yet wages cannot remain isolated. When software and other fast-growing industries offer better pay, workers can switch, so slower-productivity sectors must raise salaries to retain them. The service therefore becomes costlier relative to mass-produced goods even without becoming more wasteful. Its price increasingly reflects the worker’s opportunity cost: what that person could earn instead.

Where it shows up

The vanishing cheap repair

A repair that once seemed economically sensible may now cost enough to make replacement attractive. What changed is not necessarily the task, but the repairer’s alternative wage.

Software pulls on distant wages

High software salaries affect more than software firms. Other industries must pay more because their employees can leave, transmitting productivity gains—and labour costs—across the economy.

E2

Not every price rise is cost disease

This mechanism explains rising relative costs when labour remains hard to compress and workers have better-paid alternatives. It does not, by itself, establish that every expensive service is labour-bound or that its price rose for this reason.

Price the worker’s next-best job

When an old service looks inexplicably expensive, compare its productivity change with the wages available to the person providing it. Before blaming greed or lost efficiency, ask what you would have to pay to keep that worker from moving to a faster-growing sector.
