New evidence on the sources of EU countries’ productivity growth—industry growth differences from R&D and competition

Recent studies on productivity growth show how competition affects innovation and TFP growth in OECD countries, but do not explicitly account for sectoral parameter heterogeneity. This paper examines whether competition and innovation have a direct effect on labor productivity growth in EU goods-producing industries separated by three different industry types. The results show that the effect of R&D on labor productivity growth is not equal across industries, but rather depends on the innovation activities of sectors. The same is true for competition and labor productivity growth. The empirical evidence indicates that in unleveled industries (i.e. industries characterized by technologically unequal firms) like Specialized Goods Suppliers and Science-Based Innovators strong labor productivity growth originates with decreased competition and increased R&D, thereby supporting Schumpeterian arguments. The findings suggest Schumpeterian effects in Supplier-Dominated Goods-Producing Industries, but reveal decreasing labor productivity growth in these sectors when competition is strongly restricted.
