With infinite horizon, optimal rules for sequential search from a known distribution feature a constant reservation value that is independent of whether recall of past options is possible. We extend this result to the the case when there are multiple distributions to choose from: it is optimal...

This paper provides a theory of strategic innovation project choice by incumbents and start-ups. We show that prohibiting killer acquisitions strictly reduces the variety of innovation projects. By contrast, we find that prohibiting other acquisitions only has a weakly negative innovation...

This paper provides a theory of strategic innovation project choice by incumbents and start-ups. We apply this theory to identify the effects of prohibiting start-up acquisitions. We differentiate between killer acquisitions (when the incumbent does not commercialize the acquired start-up's...

This paper provides a novel theory of research joint ventures for financially constrained firms. When firms choose R&D portfolios, an RJV can help to coordinate research efforts, reducing investments in duplicate projects. This can free up resources, increase the variety of pursued projects and...

This paper provides a theory of strategic innovation project choice by incumbents and start-ups which serves as a foundation for the analysis of acquisition policy. We show that prohibiting acquisitions has a weakly negative innovation effect. We provide conditions determining the size of the...

This paper considers the optimal design of dynamic research tournaments when the buyer can set time-dependent prizes. We derive the buyer-optimal tournament and show that it entails an increasing prize schedule. Remarkably, this allows the buyer to implement a global stopping rule. In...
