Research Abstract

We study earnings management and the market performance of Japanese firms in stock-for-stock mergers.
We find (1) consistent with previous studies such as Erickson and Wang [1999], acquiring firms especially for group reorganization manage earnings upward preceding a stock swap announcement in order to lower the merger cost ; (2) the effect of merger on acquiring firms' stock prices is totally positive around a stock merger announcement ; (3) the merger for group reorganization has smaller effect on acquiring firms' stock prices than the merger for others ; (4) preceding stock-for-stock mergers, the market does not react to the earnings management of the acquiring firms for group reorganization ; and (5) around a stock merger announcement, the market reacts negatively to the earnings management on the latest two-interim periods prior to the announcement and discounts the stock price.
