We study social learning and innovation in an overlapping generations model, emphasizing the trade-off between marginal innovation (combining existing technologies) and radical innovation (breaking new ground). We characterize both short-term and long-term dynamics of innovation, and the...

By including the effects of learning over time on both the production of components and their integration into complete products, we develop an engineering-based model of outsourcing. This model provides an alternative explanation for much of what other outsourcing theories predict, as well as...

In this paper I propose a novel abstract mechanism for the creation and diffusion of knowledge and use an agent based modelling approach to explore it. The mechanism takes into account the relation between the phenomena that agents attempt to explain and the stocks of knowledge available in a...

I study the impact of capital market imperfections on the exercise of a real option. An entrepreneur has private information about a venture for which she seeks outside funding. An initial investment gives access to a continuous flow of information about the project. The duration of that...

This study identifies information accessibility as a determinant of corporate innovation. Using the sudden termination of Google's search services in China, we find a persistently large negative effect on the intensity and quality of innovation among firms relying on foreign technology. The...

We develop a framework in which: (i) a firm can have a new product tested publicly before launch; and (ii) tests vary in toughness, holding expertise fixed. Price flexibility boosts the strong positive impact on consumer beliefs of passing a tough test and mitigates the strong negative impact of...
