People and policymakers in many developed countries are concerned that domestic firms appear to be increasingly locating their research and development activities abroad and may at the same time erode the national scientific capabilities. However, according to Jaana Rahko’s doctoral dissertation this worry seems to be exaggerated. Her dissertation on the field of Economics presents research results showing that international research and development (R&D) activities increase the patenting and productivity of firms. She will defend her thesis at the University of Vaasa.
