We analyze the effect of a firm's innovation activities on its likelihood to be acquired and the takeover premium using a large sample of M&A transactions. We show that firms with larger innovation outputs and R&D investments are more likely to be acquired, receive unsolicited bids, and receive multiple bids. The takeover premium increases with the target firm's innovation output, and this positive relation is stronger when there are more competing bidders, when acquiring firms’ product markets are competitive, and when technological proximity is lower in the acquiring firms’ industry. Both the acquirer's cumulative abnormal return around the announcement date and post-acquisition operating performance are positively related to the target firm's innovation output and R&D spending.

This paper shows that hedge fund activism is associated with a decrease in mergers and acquisitions (M&A) and offer premiums and an increase in stock and operating performance. Activist hedge funds improve target firms’ M&A performance by reducing poor M&A, diversifying M&A, and the M&A of firms with multiple business segments. Activist hedge funds improve target firms’ M&A decisions by influencing their governance practices. We show that our results are unlikely driven by selection bias. Overall, activist hedge funds play an important role in the market for corporate control by increasing the efficiency of target firms’ M&A activities through interventions.

We study the disciplinary role of short-maturity debt in cash-rich firms. We report evidence that such debt mitigates cash-rich firms' overinvestment in acquisitions. The disciplinary role is mostly concentrated among cash-rich firms that are weakly governed and have limited access to the public debt market and is also more pronounced for cash-rich firms that operate in less competitive industries. Furthermore, for cash-rich acquirers, high levels of short-maturity debt are associated with higher acquisition announcement returns and better post-acquisition operating performance. Overall, our results highlight the effective role of short-maturity debt in reducing agency cost.
