Universities are a key institution in the US innovation system and an important aspect of their involvement is the role they play in Private-Public Partnering activities. This study seeks to gain a better understanding of the performance of university-industry research partnerships using a...

This paper examines the patenting behavior of firms in an industry characterized by rapid technological change and cumulative innovation. Recent survey evidence suggests that semiconductor firms do not rely heavily on patents to appropriate the returns to R&D, despite the strengthening of US...

This paper studies a game of strategic experimentation with two-armed bandits whose risky arm might yield a payoff only after some exponentially distributed random time. Because of free-riding, there is an inefficiently low level of experimentation in any equilibrium where the players use...

Fingold and Soskice (1988) argue that Britain is trapped in a "low-skills" equilibrium. In Redding (1996), this notion is formalized in a dynamic model which relies on strategic complementarities between firms' investments in R&D and workers' investments in human capital. In this paper, we...

Using novel data on European firms, this paper examines the effect of business group affiliation on innovation. We find that business groups foster the scale and novelty of corporate innovation. Group affiliation is particularly important in industries that rely more on external finance and have...

We analyze the incentives to disclose intermediate research results. We find that despite the help that disclosure can give to a rival, the leading innovator sometimes chooses to disclose. Disclosure signals commitment to the research project, which may induce a rival to exit. With weak product...

This paper builds a dynamic stochastic general equilibrium (DSGE) model of endogenous growth that is capable of generating substantial degrees of endogenous persistence in productivity.  When products go out of patent protection, the rush of entry into their production destroys incentives for...

The causes of the USA's exceptional economic performance are investigated by comparing American wages and prices with wages and prices in Great Britain, Egypt, and India.  Habakkuk's views on the causes of American industrial pre-eminence are reassessed.  While the USA had abundant natural...

This paper considers a model of endogenous growth with two sectors. It shows that it may be desirable to concentrate research in one sector, and so have unbalanced growth, but that the pressure of competition in research may cause the private sector to spread research too widely, and so have...

This introductory article reviews the main themes relating to the development of new knowledge-based economies. After placing their emergence in historical perspective and proposing a theoretical framework which distinguishes knowledge from information, the authors characterize the specific...
