A comparative analysis of layoff announcements and stock price reactions in the United States and Japan
比较1990-1994年间美日企业裁员公告对股价的影响，发现两国均出现负回报，但美国企业异常回报为-1.78%，日本为-0.56%，并探讨了治理结构差异。
Downsizing and layoffs are an important mechanism for U.S. firms to cope with their strategic and economic environment. In contrast, the Japanese tradition of lifetime employment limits the ability of firms to employ layoffs as a strategic measure, relegating its use to conditions of financial distress. This paper provides the first comparison of layoffs in Japan and the United States and examines stock price reactions to layoff announcements in each country from 1990 to 1994. Agency theory and Aoki's cooperative game theory are employed to discuss differences in the governance structures of U.S. and Japanese firms and their implication for stock price reactions. Results show that layoff announcements trigger negative returns for both U.S. and Japanese firms. Specifically, layoff announcements of U.S. firms are associated with a negative 1.78 percent abnormal return, while layoff announcements for Japanese firms are associated with a negative 0.56 percent abnormal return. To better understand the impact of layoffs, this study examines the relationships between stock price reactions and various layoff characteristics (such as whether the layoff is proactive or reactive or whether the layoff is the first in the industry). Implications of the findings are discussed. © 1997 John Wiley & Sons, Ltd.
