TY: JOUR T1 - R&D, structural change and productivity: the role of high and medium-high technology industries A1 - Varum, C.A. A1 - Cibrão, B. A1 - Morgado, A. A1 - Costa, J. N2 - This paper investigates the potential impact of increased R&D efforts and structural change in Portugal on labour productivity. Based on existing literature on the relation between R&D expenditures, structural change and productivity, we evaluate the contribution of R&D and hightech industries to productivity over the last 30 years. Our results confirm the importance of business R&D in the medium to high-tech sectors and of public R&D, as they stimulate productivity growth. However, we cannot support the hypothosis that productivity growth was primarily rooted in the development of medium-high technology industries.
