In page Recession:

"

Productivity tends to fall in the early stages of a recession, then rises again as weaker firms close. The variation in profitability between firms rises sharply.[citation needed] The fall in productivity could also be attributed to several macro-economic factors, such as the loss in productivity observed across the UK due to Brexit, which may create a mini-recession in the region. Global epidemics, such as COVID-19, could be another example, since they disrupt the global supply chain or prevent the movement of goods, services, and people.
