In this paper, we examine the importnace of year, industry, corporate - parent, and business - specific effects on the profitability of U. S. public corporations within specific 4 - digit SIC categories. Our results indicate that year, industry, corporate - parent, and business - specific effects account for 2 percent, 19 percent, 4 percent, and 32 percent, respectively, of the aggregate variance in profitability. We also find that the importance of the effects differs substantially across broad economic sectors. Industry effects account for a smaller portion of profit variance in manufacturing, but a larger portion in lodging / entertainment, services, wholesale / retail trade, and transportation. Across all sectors we find a negative covariance between corporate - parent and industry effects. A detailed analysis suggests that industry, corporate - parent, and business - specific are related in complex ways.
