Explanatory Power of BVPS and REPS Over Time
Following Collins et al. (1997) and King and Langli (1998), we examine changes
across time in the explanatory power of book value and residual earnings. The incremental
explanatory power of BVPS and REPS differ greatly over time and across countries. The time patterns revealed in the regressions are illustrated in Fig. 1. The time patterns show
that the overall explanatory power is increasing for Korea, the Philippines, and Taiwan,
and declining for Indonesia and Thailand and mixed for Malaysia. Similarly, the
incremental explanatory power of BVPS is increasing for Korea, the Philippines, and
Taiwan, decreasing for Indonesia and Thailand, and mixed for Malaysia. For the
incremental explanatory power of residual earnings, results show increases in the
Philippines, Taiwan, and Thailand, decreases for Korea, and mixed patterns for Indonesia
and Malaysia.
