我们对日本废纸与原浆混合比例的隐瞒进行了事件研究。通过对2007年5月30日至2008年1月18日造纸行业10家公司的调查，我们清楚地看到，相关公司的股价受到隐瞒废纸掺混比例消息的影响。此外，发现第二个事件的影响比第一个事件的影响更大。因此，主要公司的隐瞒会对在此期间没有隐瞒信息的非主要公司的股价产生负面影响。因此，利空消息受到市场的负面评价，这种影响已在整个造纸行业蔓延。
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.
