We study how exploration versus exploitation innovations impact economic growth through a tractable endogenous growth framework that contains multiple innovation sizes, multi-product firms, and entry/exit. Firms invest in exploration R&D to acquire new product lines and exploitation R&D to...

This paper considers the role of Rosenbergian uncertainty (i.e., economic uncertainties that arise after successful invention) in shaping appropriability for start-up innovators. Rather than assuming that the appropriability regime surrounding an innovation is exogenous, we focus on the...

When startup innovation involves a potentially disruptive technology - initially lagging in the predominant performance metric, but with a potentially favorable trajectory of improvement - incumbents may be wary of engaging in cooperative commercialization with the startup. While the prevailing...

Innovation is important for firm performance and broader economic growth. But breakthrough innovations necessarily require greater risk-taking than more incremental approaches. To understand how managers respond to uncertainty when making research and development decisions, we conducted three...

A central premise of research in the strategic management of innovation is that start-ups are able to leverage emerging technological trajectories as a source of competitive advantage. But, if the potential for a technology is given by the fundamental character of a given technological...

How does firm entry affect innovation incentives and productivity growth in incumbent firms? Micro-data suggests that there is heterogeneity across industries--incumbents in technologically advanced industries react positively to foreign firm entry, but not in laggard industries. To explain this...

We examine how executives' behavior outside the workplace, as measured by their ownership of luxury goods (low "frugality") and prior legal infractions, is related to financial reporting risk. We predict and find that CEOs and CFOs with a legal record are more likely to perpetrate fraud. In...

We present a model in which managers are risk-averse and firms compete for scarce managerial talent ("alpha"). When managers are not mobile across firms, firms provide efficient compensation, which allows for learning about managerial talent and for insurance of low-quality managers. When...

We identify the impact of local firm concentration on incumbent performance with a quasi natural experiment. When Germany was divided after World War II, many firms in the machine tool industry fled the Soviet occupied zone to prevent expropriation. We show that the regional location decisions...

This paper documents the role of angel funding for the growth, survival, and access to follow-on funding of high-growth start-up firms. We use a regression discontinuity approach to control for unobserved heterogeneity between firms that obtain funding and those that do not. This technique...
