We investigate the role of accrual accounting in the asymmetrically timely recognition (incorporation in reported earnings) of gains and losses. Timely recognition requires accruals when it precedes complete realization of the gains and losses in cash. We show that nonlinear accruals models incorporating the asymmetry in gain and loss recognition (timelier loss recognition, or conditional conservatism) offer a substantial specification improvement, explaining substantially more variation in accruals than equivalent linear specifications. Conversely, conventional linear accruals models, by omitting the loss recognition asymmetry, exhibit substantial attenuation bias and offer a comparatively poor specification of the accounting accrual process. Linear specifications also understate the ability of current earnings to predict future cash flows. These findings have implications for our understanding of accrual accounting and conservatism, as well as for researchers estimating discretionary accruals, earnings management, and earnings quality.

This paper examines whether earnings momentum and price momentum are related. Both in time-series as well as in cross-sectional asset pricing tests, we find that price momentum is captured by the systematic component of earnings momentum. The predictive power of past returns is subsumed by a zero-investment portfolio that is long on stocks with high earnings surprises and short on stocks with low earnings surprises. Further, returns to the earnings-based zero-investment portfolio are significantly related to future macroeconomic activities, including growth in GDP, industrial production, consumption, labor income, inflation, and T-bill returns.
