Diagnose the Unemployment
The idea
From a description of a country, say whether its unemployment is mainly cyclical or mainly natural rate, and name the matching policy. Two questions: is output below potential, and has the rate persisted through good years as well as bad? Persistence through expansions points to institutions rather than to the cycle.
In practice
An economy whose unemployment rose three points in a downturn and fell back as output recovered had cyclical unemployment, and the remedies are demand policies with the stabilisers left to work. An economy whose unemployment has sat several points above its neighbours' for two decades, through expansions and contractions alike, has a natural-rate problem, and demand policy will not move it. A third economy has both, which is the usual case, and the two parts need different treatments at the same time.
Where people slip
The natural-rate explanation usually offered is the weight of hiring and firing rules, and the course voices both halves of that without a verdict: the same rules that protect workers in a job can make employers slower to create one. The anchor's own illustration is a threshold effect, where far more firms sit immediately below an employee count that triggers new obligations than immediately above it.
