This article analyzes the manifold situations in which the efficient-market hypothesis (EMH) has influenced — or has failed to influence — federal securities regulation and state corporate law, and the prospective roles for the EMH in these contexts. In federal securities regulation, the EMH...

While takeover targets earn significant abnormal returns, studies tend to find no abnormal returns from investing in predicted takeover targets. In this study, we show that the difficulty of correctly identifying targets ex ante does not fully explain the below-expected returns to target...

Managers frequently project high synergistic gains when announcing M&As. This paper analyzes when promised synergies are value-relevant. Using text analytical methods, we only find a positive relationship between synergy projections and announcement returns when promised numerical projections...
