The event study or event study method (ESM) is an empirical technique for capturing investors’ reaction to an event affecting one or more publicly traded firms. The ESM has been little employed in international business (IB) research despite its frequency in accounting, economics, and finance; for example, only two percent of the empirical articles in JIBS over 1970–2019 include an event study. While this scarcity could indicate a lack of demand, we argue that the field of IB studies offers many interesting and important research opportunities for an event study. We believe that the challenges arise primarily from the supply side, because conducting an event study involves overcoming a variety of data and analytical hurdles. We examine these methodological challenges and offer practical solutions designed to encourage adoption of the ESM. An online appendix with coding and examples provides additional resources.

事件研究或事件研究方法(ESM) 是一种经验技术，用于捕捉投资者对影响一个或多个上市公司的事件的反应。尽管 ESM 在会计、经济和金融领域的应用频率很高，但它在国际商务 (IB) 研究中的应用却很少；例如，JIBS中只有 2% 的实证文章1970-2019 年包括一项事件研究。虽然这种稀缺性可能表明需求不足，但我们认为 IB 研究领域为事件研究提供了许多有趣且重要的研究机会。我们认为挑战主要来自供应方面，因为进行事件研究涉及克服各种数据和分析障碍。我们研究了这些方法上的挑战，并提供了旨在鼓励采用 ESM 的实用解决方案。带有编码和示例的在线附录提供了额外的资源。
