The prior literature has established that the internationalization of corporate R&D is motivated by access to new markets and technological knowledge. However, the empirical literature has overlooked whether the market and technological characteristics of R&D host countries influence the firm-level productivity gains from international R&D. This study empirically examines whether international R&D activities affect the productivity of European multinational firms. Estimating an R&D augmented production function shows that the output elasticity of R&D depends positively on the share of international R&D activities. The analysis further shows that the improvements are associated only with offshore R&D in host countries that have experienced fast economic growth or that are technologically stronger than firms' home country.
