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.
