| Summary: | 碩士 === 國立臺灣大學 === 會計學研究所 === 91 === The objective of this thesis is to test the market efficiency of financial forecasts. Precedent researches on financial forecasts mostly focused on the study of information content, but their empirical results are inconsistent.

1. The market is under-reaction to earnings-to-price ratios based on forecasted earnings per share.
2. The market is under-reaction to Ohlson model based on financial forecasts.
