Many studies investigate the relationship between R&D expenditures as an input and patents as an intermediate product or output of a knowledge production function. We suggest that the productivity of research in patent production functions has been underestimated in the literature, as scholars...

The models of Lucas (1993), Krugman (1987), Stokey (1988, 1991) and Young (1991) predict that productivity growth is associated with the production of increasingly sophisticated products, and that high-end goods should exhibit more productivity growth than low-end goods. This paper investigates...

Radical innovations require risk-taking. However, it is hard to find an objective measure for innovation investments that would take riskiness into account. In this paper, we investigate how a simple measure of firms’ innovation investments, namely the employee share of managers and...

The aim of this study is to investigate the relationship between a firm's R&D activities and its productivity using a unique micro data panel dataset and looking at sectoral peculiarities which may emerge; more specifically, we used an unbalanced longitudinal database consisting of 532 top...

This study presents new estimates of business R&D capital stocks for 22 countries at the aggregate and industry levels. At 9 percent of GDP, the EU business R&D capital stock falls short of its US and Japanese counterparts. Within the EU, R&D capital stocks are much lower in the southern and the...

What factors underlie industry differences in research intensity and productivity growth? We develop a multi-sector endogenous growth model allowing for industry specific parameters in the production functions for output and knowledge, and in consumer preferences. We find that long run industry...

We examine the links between innovation investment, innovation output and productivity in service enterprises. For this purpose, we use micro data from the Community Innovation Surveys 2006-2008 in Germany, Ireland, and the United Kingdom and estimate an augmented structural model which links...

Although non-R&D innovation activities account for a significant portion of innovation efforts carried out across very heterogeneous economies in Europe, how to incorporate them in to economic models is not always straightforward. For instance, the traditional macro approach to estimating the...
