Our analysis is based on contemporaneous cross-sectional regressions of accounting book values and residual earnings on stock prices (dependent variable). We analyze both the relative and the incremental explanatory power of book value and residual earnings using an approach applied previously in accounting by Biddle et al. (1995) and Collins et al. (1997). Empirical specification of the residual earnings model requires estimates of book value, residual earnings, and the horizon for residual earnings. For residual earnings estimated to terminate at time T, the model would be:
