A cross-country index of intellectual property rights in pharmaceutical inventions
Liu, Ming; La Croix, Sumner - In: Research Policy 44 (2015) 1, pp. 206-216
Building on the seminal work of Ginarte and Park (1997. Research Policy. 26, 283–301), we develop an index of property rights in pharmaceutical inventions, the Pharmaceutical Intellectual Property Protection (PIPP) Index, for 154 countries spanning 1960 to 2005. It incorporates five types of...

Credit where credit is due? The impact of project contributions and social factors on authorship and inventorship
Haeussler, Carolin; Sauermann, Henry - In: Research Policy 42 (2013) 3, pp. 688-703
We examine the extent to which different types of substantive project contributions as well as social factors predict whether a scientist is named as author on a paper and inventor on a patent resulting from the same project. Using unique survey data from over 2000 life scientists, we find that...
