Abstract:     
We incorporate revisions in expected future earnings to better represent concepts underlying the Basu (1997) discussion of conservatism and to disaggregate Basu’s asymmetric timeliness (AT) coefficient into two components that reflect conservatism by capturing asymmetry between bad and good news relating to: (i) the variance of unexpected earnings, and (ii) the covariance between unexpected earnings and revisions in expected future earnings and discount rates. We find bias in the AT measure as well as its two components, because they comove strongly with placebos that are unrelated to conservatism. Because this bias reflects asymmetries in the conditional distributions of stock prices and returns, future research should deemphasize specifications affected by such asymmetries. We also investigate a debate regarding the source of upward bias that arises when the AT measure is implemented using observed rather than unexpected earnings and returns. Our results support Patatoukas and Thomas (2011) but contradict Ball et al. (2013b).
