We estimate the magnitude of spillovers generated by 112 academic quot;superstarsquot; who died pre- maturely and unexpectedly, thus providing an exogenous source of variation in the structure of their collaborators' coauthorship networks. Following the death of a superstar, we find that...

We analyse whether research funding contests promote co-authorship. Our analysis combines Scopus publication records with data on applications to the Marsden Fund, the premiere source of funding for basic research in New Zealand. On average, and after controlling for observable and unobservable...

This article measures scientific influence by means of citations to academic papers. The data source is the Institute for Scientific Information (ISI); the scientific institutions included are the top 110 U.S. research universities; the 12 main fields that classify the data cover nearly all of...

Prior work suggests that more valuable patents are cited more. Using novel revenue data for tens of thousands of patents held by non-practicing entities (NPEs), we find that the relationship between citations and value forms an inverted-U, with fewer citations at the high end of value than in...

Research Joint Ventures (RJVs) are projects that combine the research resources of different firms. A sample of RJVs supported by the U.S. Advanced Technology Program shows that the projects yield revenues that are far less than costs. Related to this point, the RJVs are subject to...

The establishment and growth of industrial research laboratories is one of the key organizational innovations affecting technological progress in the United States in the 20th century. In this paper, we investigate the rise of industrial research laboratories in the U.S. pharmaceutical industry...

This paper explores recent trends in the size of scientific teams and in institutional collaborations. The data derive from 2.4 million scientific papers written in 110 leading U.S. research universities over the period 1981-1999. We measure team size by the number of authors on a scientific...

This article examines the involvement of agricultural and life science faculty at U.S. land grant universities in two types of university-industry relations: academic engagement (sponsored research, industry collaborations, and presentations), academic commercialization (patenting, licensing,...

An inventor's own knowledge is a key input in the innovation process. This knowledge can be built by interacting with and learning from others. This paper uses a new large-scale panel dataset on European inventors matched to their employers and patents. We document key empirical facts on...

In this paper, we develop a theoretical model of university licensing to explain why university license contracts often include payment types that differ from the fixed fees and royalties typically examined by economists. Our findings suggest that milestone payments and annual payments are...
