Abstract
We conducted an event study on the concealment of the blending ratio of waste paper with virgin pulp in Japan. By investigating 10 companies in the paper industry between May 30, 2007 and January 18, 2008, we clearly show that stock prices of the relevant companies were affected by the news on the concealment of the blending ratio of waste paper. In addition, the impact of the second event was found to be greater than that of the first event. Therefore, the concealment of major companies negatively affects the stock prices of non-major companies, which did not conceal information during this period. Thus, bad news is negatively assessed by the market, and this influence has spread in the paper industry in general.
