TL;DR: In this paper, the authors developed new indicators of accumulated academic science and tested their explanatory power on productivity data from manufacturing industries and found that knowledge is a major contributor to productivity growth.

TL;DR: In this article, the authors measured team size by the number of authors on a scientific paper and found that team size increases by 50 percent over a 19-year period, indicating a sudden decline in the cost of collaboration, perhaps due to improvements in telecommunications.

TL;DR: In this article, the authors explore recent trends in the size of scientific teams and in institutional collaborations and find that the trend towards more geographically dispersed scientific teams accelerates beginning with papers published at the start of the 1990s, which suggests a sharp decline in the cost of collaboration.

TL;DR: The authors found that the effects of parent firm RD that productivity appears to depend on RD and that spillovers from technologically related firms are significant but also depend on R&D intensity rather than on total industry R&DI.

TL;DR: In this article, the authors studied the localization of academic and industrial knowledge spillovers and found that academic spillovers are more localized than industrial spillovers, which reflect open science and the industry-university cooperative movement, which encourage firms to work with local universities, so that localization coincides with the public goods nature of science.
