This study investigates whether listed companies change accounting methods primarily to smooth reported earnings and income taxes, and how the informations of accounting changes affect stock prices. The information of accounting changes includes tax savings, income smoothing, and tax smoothing. The results show that accounting changes are used as an income or tax smoothing instrument(device) in the listed companies which changed their accounting methods from 1991 to 1996. Also, those have a tendency to smooth income and tax simultaneously by accounting changes. Tax savings, income smoothing, and tax smoothing variables by accounting changes are irrelevant to stock prices. Income smoothing variable has a positive association with stock returns in the periods that the abnormal returns cumulated over four months. But tax smoothing variable has a negative association with stock returns in the same periods. More studies on the firms' accounting changes are needed to get a definitive conclusion.
