This study revisits this hypothesis using OECD data for the period 1980-2000. It extends the literature in three ways: it develops new R&D price deflators to account for R&D price inflation; it employs two complementary indicators of patent quality, and applies dynamic panel data estimation techniques. When corrections are made for cross-sectional dependence, two major findings emerge: international inventor collaboration is an important indicator of patent quality, and there is strong support for the maintained hypothesis. 2005-08 published Victoria University 27 56166 2 2385675 dark_document 56166 Messinis George.pdf application/pdf 576c3b019f5e6112a1449002bfeadfc3 MD5 75089 2020-07-21 01:57:27 109 3 3 application/pdf text Submission & Permission Form en staffonly
