Earnings Call Slide Deck
研究了上市公司盈利电话幻灯片的特点及其使用决定因素，发现幻灯片虽未提供增量信息，但通过图表、关键信息总结和提前发布三种机制显著减少用户信息处理时间。
In recent years, earnings call slide decks (hereafter, earnings decks) have become increasingly common in the earnings announcements of public firms. In this paper, I examine the characteristics of earnings decks and the determinants of firms’ use of them. More importantly, I study their capital market roles. While I fail to find evidence that earnings decks on average offer information incremental to traditional disclosures, such as press releases and conference calls, they significantly reduce users’ information processing time. My analyses reveal three mechanisms that contribute to this acceleration: inclusion of visuals (e.g., charts and tables), summarization of key information, and release prior to earnings calls. Overall, this study documents a novel aspect of earnings announcements and highlights the role of multimedia elements in reducing information processing costs of corporate disclosures.
