讲座简介：

We examine whether and how firms mimic peer disclosures in corporate earnings calls, integrating theories of informational cascades, herding behavior, and institutional isomorphism within a Bayesian disclosure framework. We use a state-of-the-art semantic similarity measure based on large language models to capture subtle similarities in earnings call language. By taking advantage of the staggered timing of earnings calls, we find that firms tend to adopt disclosure language resembling that of peers whose earlier earnings calls elicited positive investor reactions, particularly in forward-looking statements, where managerial discretion is highest. While this strategic mimicry yields immediate benefits – generating more positive short-term market responses around the mimicking firms’ own earnings calls – it predicts weaker subsequent operating performance and has no robust association with capital investments. Our findings highlight an underappreciated strategic dimension of corporate communication: firms closely monitor competitors’ successful narratives, actively updating their disclosure strategies to influence short-term investor perceptions, with important implications for market efficiency.
