This paper explores how and why collaboration with different types of partners and the position within a research network can affect firms' innovative performance in terms of product innovations. A detailed empirical analysis is carried out in the biotechnology and pharmaceutical industry. This...

We relate innovation to sales growth for incumbent firms in high-tech sectors. A firm, on average, experiences only modest growth and may grow for a number of reasons that may or may not be related to innovativeness. However, given that the returns to innovation are highly skewed and that growth...

This paper discusses the impact of a firm's technology portfolio on its market value. Two concepts are used to characterize a firm's portfolio: the number of technological fields and the degree of relatedness within the portfolio characterized by the amount of joint occurrences of patents in...

We relate innovation to sales growth for incumbent firms in high-tech sectors. A firm, on average, experiences only modest growth and may grow for a number of reasons that may or may not be related to "innovativeness". However, given that the returns to innovation are highly skewed and that...

We build a new concordance between the NBER Patent Data and US Census micro-data, and use it to examine what happens when firms patent. We find strong evidence that increases in patent stock are associated with increases in firm size and scope as well as with changes in factor intensity. We find...

While explaining cluster internal impacts on cluster development, cluster life cycle theory fails to explain the influence of cluster external factors. Based on a multiscalar approach, this study investigates factors causing change within an agritech cluster applying a qualitative approach. Main...
