Prior research provides ambiguous results regarding the performance of international acquisitions. Drawing on a survey of 248 acquisitions, we find that acquirers enhance their capabilities when they buy a target with a multinational geographic scope. A financial event study uses a subsample of...

We contribute a novel approach to the existing literature on the effects of restructuring on Ramp;D investment by focussing on a single industry, chemicals. The chemical industry is very research intensive and has experienced thorough restructuring since the early 1980s. By focussing on a single...

This study investigates how national institutions influence innovation in a science-based industry. The context is the biotechnology industry in the United States and France, two countries with strong scientific and financial resources, but very different experiences in innovating from...

Researchers studying innovation increasingly use indicators based on patent citations. However, it is well known that not all citations originate from applicants--patent examiners contribute to citations listed in issued patents--and that this could complicate interpretation of findings in this...

Analysis of patent citations is a core methodology in the study of knowledge diffusion. However, citations made by patent examiners have not been separately reported, adding unknown noise to the data. We leverage a recent change in the reporting of patent data showing citations added by...

Prior art patent citations have become a popular measure of patent quality and knowledge flow between firms. Interpreting these measurements is complicated, in some cases, because prior art citations are added by patent examiners as well as by patent applicants. The U.S. Patent and Trademark...

This study looks at the United States biotechnology industry as a community of practice caught between two evolutionary logics by which valuable scientific knowledge and valuable innovations are selected. We analyze the publications and patents of 116 biotechnology firms during the period...
