Cyclical unemployment results from the normal ups and
downs of the economy, often referred to as the business
cycle. As the economy slows or enters a recession, firms
reduce hiring or lay individuals off and cyclical
unemployment rises. When the economy grows, firms hire
and cyclical unemployment falls. Short-term deviations are
mostly attributable to cyclical factors, and are difficult to
predict, as was the case with the COVID-19 pandemic.
When the economy is operating at a sustainable level given
its available inputs, cyclical unemployment is zero and the
unemployment rate is roughly equal to the sum of structural
and frictional unemployment. This is referred to as the
