Contraction

In a business cycle, the time between the peak and the bottom. That is, a contraction occurs between the end of economic growth and the end of the subsequent recession. Contractions are characterized by layoffs, a decline in GDP, and other negative factors. However, historically, contractions have tended not to last as long as expansions.
