Regularities in GDP Fluctuations
• Business Cycles are fluctuations about trend in real GDP.
• The turning points in the deviations of real GDP from trend are peaks and troughs.
• Persistent positive deviations from trend are booms and persistent negative deviations from trend are recessions.

Deviations From Trend in Real GDP are Irregular
• The fluctuations in GDP about trend are quite choppy.
• There is no regularity in the amplitude of fluctuations in real GDP about trend.
• There is no regularity in the frequency of fluctuations in real GDP about trend.

Correlation with Real GDP
• If the deviations from trend in a macroeconomic variable are positively (negatively) correlated with the deviations from trend in real GDP, then that variable is procyclical (countercyclical).
• If a macroeconomic variable is neither procyclical nor countercyclical, it is acyclical.

Behavior of Key Macroeconomic Variables
• Components of GDP: consumption and investment.
• Nominal variables: price level and money supply.
• Labor market variables: employment, real wage, average labor productivity.
