| Research Abstract |
By analyzing the Japanese firm data, we investigated the theoretical measures that were firm values calculated by inputting the accounting figures into the Ohlson model. First, in the viewpoint of difference of posited assumptions, extant empirical models based on the Ohlson model were surveyed, and we presented a new empirical model incorporating 'the residual income dynamics' additionally. Next, we calculated several theoretical measures of every sample firm by using surveyed empirical models, and examined. (1) Value relevance analysis and (2) Investment performance analysis about those measures.
(1) We examined the correlation between the theoretical values and stock prices. Book value of net assets was relatively higher correlation than the theoretical measures in both cases of consolidated accounting data and parent-only accounting data, that was different from the result by Frankel and Lee (1998 and 1999, henceforth FL). The theoretical measures using analysts' earnings forecasts had higher value relevance than those using actual earnings, and we found incorporating 'the residual income dynamics' into the Ohlson model improved the value relevance.
(2) The ability of the theoretical measure to predict future stock returns was analyzed. Our result showed that the ability of the theoretical measures was worse than Book to Market ratio for overall period. This result was not the same as FL, and we found only the result for the 1994-1995 sub-period was consistent with FL. Our sample periods included the bubble and post-bubble period, therefore we thought the results may be strongly effected by economic conditions.
