The document discusses the four phases of business cycles: depressions, recovery, boom, and recession. It provides details on the key characteristics of each phase. Depressions are characterized by extremely low demand, falling inflation, rising unemployment, and companies cutting costs through layoffs. Recovery sees an upturn in demand, production, investment, falling unemployment as employment rises. Booms have accelerated and prolonged increased demand exceeding sustainable output, inflation rising, and shortages emerging. Recessions similarly have falling demand, lower inflation, rising unemployment, and companies cutting prices to sustain business.
