This study examines the relationship between accounting and market-value measures of profitability for individual firms. Differences in measures of profitability are observed both between and within industry groups and thus cannot be explained by differences in uncontrolled industry-specific influences. We suggest that both accounting and market can be used as unique but imperfect indicators of profitability. Using a LISREL model approach, we find R & D intensity, television advertising intensity, leverage, and industry growth to be important determinants of firm profits.
