Unscheduled stock options to target CEOs are a non-trivial phenomenon during private merger negotiations. In 920 acquisition bids during 1999-2007, over 13% of targets grant them. These options substitute for golden parachutes and compensate target CEOs for benefits they forfeit because of the...

We examine the causal effects of terrorism on inventor productivity and mobility. During the five-year window after terrorist attacks, inventors close to the strikes are more likely to move to distant companies. While the inventors that continue working for firms near the attacks exhibit a...

Acquirer CEOs with experience in the target's industry supply chain (‘supply chain CEOs') are associated with wealth effects of first-order importance: they earn 1% higher merger announcement returns. Conversely, their targets get a lower share of the merger gains. Acquisitions by supply chain...

We contrast the investment strategies of hedge funds and mutual funds around M&A transactions. We find that hedge funds increase their holdings of soon-to-be takeover targets by 7.5% during the quarter before M&A announcements. Conversely, mutual funds reduce their equity holdings in impending...

We analyze 7.7 million patents via textual analysis to develop a novel patent-to-patent measure of innovation similarity among firms. With this measure, we investigate whether stock price movements reveal information about firms' technological connectedness. We find that investors impound...

Firms exhibit a US$106MM average market capitalization decline when a lawsuit against their joint venture partner is announced. Following their partner's lawsuit, the probability of facing similar litigation increases for other firms in the venture, and such legal action is 2.3 times more likely...

In this paper we show that when bidders are in the Samp;P 500 Index, risk arbitrage portfolio returns are 85 percent larger than when they are not. We also show that acquisitions by Samp;P 500 buyers are more likely to be completed, and take less time to complete, than are deals by different...
