| Abstract: | This paper seeks to characterize the behavior of profits over the business cycle as a model for analyzing any economic series by a practicing business economist. It addresses three fundamental questions about profits that are common and critical to identifying the behavior of any macroeconomic series—mean-reversion, volatility, and trend. First, does profit growth over time exhibit mean-reverting behavior? Second, how volatile are profits, and does this volatility obscure the message of average profit growth? Third, how can we estimate a long-run trend growth component for profits and thereby separate profit cycles from its long-run trend growth component? |
