Which Remedy Fits?
The idea
The remedy follows the diagnosis, and mismatching them wastes the policy. Cyclical unemployment comes from too little total demand, so the remedies are the demand policies of units nine through fourteen: the jobs come back when spending does. Frictional and structural unemployment persist at full employment, so demand policy cannot touch them. They call for better job information, help with search and relocation, and retraining. Using demand policy against structural unemployment raises prices without filling the jobs, because the workers still lack the skills the jobs need.
In practice
Worked example: a region loses its mines permanently and unemployment there stays high through a national boom. That is structural, and a national stimulus will not reopen the mines. Retraining and help with moving might. By contrast, a nationwide rise in unemployment during a recession, spread across every industry, is cyclical, and reviving demand is exactly the remedy.
Where people slip
The hard case is the mixed one, which is most real recessions: some of the unemployment is cyclical and some is structural, and the shares are not observable at the time. That is why policy arguments during a downturn so often turn on a diagnosis nobody can yet confirm.
