Exploiting exogenous variations in corporate ratings due to sovereign credit downgrades and sovereign ceiling policies, we assess how firms respond to a reduction in credit ratings. We find that firms bounded by the sovereign ceiling significantly increase information production in response to a sovereign downgrade. The effects are stronger for firms relying more heavily on external finance and operating in a more opaque environment. Enhanced information production, in turn, affects firms’ subsequent access to bond markets. These findings suggest that firms actively manage information environments to maintain access to public debt markets.

Inducing firms to make specialized investments through bilateral contracts can be challenging because of potential hold- up problems. Such contracting difficulties have long been argued to be an important reason for acquisitions. To evaluate the extent to which this motivation leads to mergers, we perform a textual analysis of the patents filed by the same lead inventors of the target firms before and after the mergers. We find that patents of inventors from target firms become 28.9% to 46.8% more specific to those of acquirers’ inventors following completed mergers, benchmarked against patents filed by targets and a group of counterfactual acquirers. This pattern is stronger for vertical mergers that are likely to require specialized investments. There is no change in the specificity of patents for mergers that are announced but not consummated. Overall, we provide empirical evidence that contracting issues in motivating specialized investment can be a motive for acquisitions.

Many M&A deal announcements are accompanied with a conference call to discuss deal details and address market participants’ demand for information. We find that calls are associated with positive market reactions and a higher likelihood of deal completion. Using a topic modelling approach, we uncover 20 highly interpretable topics from the call transcripts. Market reactions are more (less) positive when the call communicates more “hard” (“soft”) information, revealing different disclosure strategies depending on deal quality. Governance-related issues, although not significantly correlated with stock returns, are prominently discussed and related to the latent motivation for holding calls.
