This article reviews evidence on the changing structure of the US innovation ecosystem and then develops a simple model of the rise and fall of the large corporate lab. We suggest that the growth of American universities allowed at first the formation of large corporate labs by training scientists to work in industrial labs. Subsequently, however, start-up invention spurred by university research provided an increasingly attractive alternative to internal research, leading to the demise of the l...

We study how the inventive capability of a firm conditions its participation in a division of innovative labor. Capable firms are, by definition, able to invent; for them, external inventions substitute for their own R&D. However, external knowledge is an input into internal invention, and thus, more valuable to firms with inventive capability. Using a simple model of innovation and imitation, we explore how inventive capability affects a firm’s R&D investments, and thus whether and how it innov...

The bio-pharmaceutical industry has been an important empirical setting for strategy research since the 1970s, when it was noted to outperform other industries due to its firms’ diversification strategies and to barriers to entry that arise from regulatory requirements and other characteristics of the industry. Since then, scholars have examined multiple issues of strategy and performance in the sector, with the bio-pharma industry continuing to be a popular empirical context for testing theoret...

Spillover of knowledge is considered to be an important cause of agglomeration of inventive activity. Many studies argue that knowledge spillovers are localized based on the observation that patents tend to cite nearby patents disproportionately. Specifically, patent citations are typically interpreted as marking the transmission of knowledge from the cited invention to the citing invention. The localization of patent citations is therefore taken as evidence that such knowledge transmission is a...

Most technology startups are set up for exit through acquisition by large corporations. In choosing when to sell, startups face a tradeoff. Early acquisition reduces execution errors but later acquisition improves the likelihood of finding a better match since in the early market, there are fewer buyers because early acquisition requires costly absorptive capacity. Moreover, the buyer’s decision to invest in absorptive capacity is related to the startup’s decision about the timing of the exit sa...

The present paper is concerned with reflection and transmission of a plane, elastic, inhomogeneous wave striking obliquely at some discontinuity inside a porous medium composed of two distinct solids and saturated by two immiscible fluids. It is found that four P and two SV -waves are reflected, while four P and two SV -waves are transmitted at the interface. All reflected and transmitted waves are inhomogeneous in nature and specified with different directions of propagation and attenuation vec...

Research summary: In this article, we document a shift away from science by large corporations between 1980 and 2006. We find that publications by company scientists have declined over time in a range of industries. We also find that the value attributable to scientific research has dropped, whereas the value attributable to technical knowledge (as measured by patents) has remained stable. These trends are unlikely to be driven principally by changes in publication practices. Furthermore, scienc...
