Q

Cyclical Unemployment

A

Cyclical unemployment is a factor of overall unemployment that relates to the cyclical trends in growth and production that occur within the business cycle. When business cycles are at their peak, cyclical unemployment will be low because total economic output is being maximized. When economic output falls, as measured by the gross domestic product (GDP), the business cycle is low and cyclical unemployment will rise.

Q

Structural Unemployment

A

Structural unemployment is a longer-lasting form of unemployment caused by fundamental shifts in an economy and exacerbated by extraneous factors such as technology, competition and government policy. Reasons why structural unemployment occurs include workers’ lack of requisite job skills or that workers live too far from regions where jobs are available and cannot move closer. Jobs are available, but there is a serious mismatch between what companies need and what workers can offer.

- M = money supply
