How do non-practicing entities (“Patent Trolls”) impact innovation and technological progress? We employ unprecedented access to NPE-derived patent and financial data and a novel model to answer this question. We find that NPEs tend to acquire litigation-prone patents from small firms and...

Technological progress builds upon itself, with the expansion of invention in one domain propelling future work in linked fields. Our analysis uses 1.8 million U.S. patents and their citation properties to map the innovation network and its strength. Past innovation network structures are...

This paper examines the diversity of the types of links of firms to science and their effect on innovation performance for a sample of Belgian firms. While at the industry level links to science are highly related to the R&D intensity of the sector, we show that there exists considerable...

This paper discusses the diversity of mechanisms which firms can deploy to link to science and how science links are associated with their innovation performance. Using a sample of Flemish firms, we show that there exists considerable heterogeneity in the type of links to science at the firm...

In this paper, we review the literature on declining business dynamism and its implications in the United States and propose a unifying theory to analyze the symptoms and the potential causes of this decline. We first highlight 10 pronounced stylized facts related to declining business dynamism...
