patent quantity is driven by knowledge exchange rather than joint R&D. Firms engaged in joint R&D, on the other hand, receive … more forward citations per patent indicating that joint R&D enhances patent quality. In light of literature on strategic …&D Collaboration ; Knowledge Exchange ; Patents ; Innovation ; Count Data Models …

on the basis of patent data was conducted and a weighted bivariate probit model was estimated on the citation probability … of industry and science on the basis of a combined sample of citing and cited patent pairs and an equal number of control … patent pairs. The empirical results suggest that there are considerable differences in the citation probability. Cultural …

This paper analyzes externalities of patent box regimes in Europe. Tax reductions in foreign affiliates of a firm that … specific characteristics of patent box regimes, we show that patent box regimes without nexus requirements for tax …-efficient reallocation of patent profits induce positive spillovers within multinational groups.
