Conservatism Measures that Control for the Effects of Economic Rents on Stock Returns

Recent studies show that regression-based estimates of accounting conservatism reflect both differences in the asymmetric recognition of bad news and differences in asset composition. In particular, a firm’s market value and returns reflect both assets-in-place and expected future rents, while book values tend to reflect only assets-in-place. We propose two tests that remove the effect of asset composition on cross-sectional comparisons of accounting conservatism. First, a test based on a ratio of regression coefficients allows for valid cross-sectional comparisons of conservatism relative to overall news recognition. Second, in some cases, researchers can separately identify and make cross-sectional comparisons of the fraction of good news recognized and the fraction of bad news recognized. The estimates in this second scenario use a regression of earnings on returns interacted with a book-to-market ratio. We validate our model by deriving and testing several predictions based on it.
