This paper documents the puzzling evidence that a substantial number of large public non-financial US firms follow a zero-debt policy. Over the 1962-2009 period, on average 10.2% of such firms have zero debt and almost 22% have less than 5% book leverage ratio. Neither industry nor size can...

We provide a model and empirical tests showing how an active acquisition market affects firm incentives to innovate and conduct R&D. Our model shows that small firms optimally may decide to innovate more when they can sell out to larger firms. Large firms may find it disadvantageous to engage in...

We examine how product differentiation influences mergers and acquisitions and the ability of firms to exploit product market synergies. Using novel text-based analysis of firm 10K product descriptions, we find three key results. (1) Firms are more likely to enter restructuring transactions when...
