The paper empirically analyses the effect of R&D activities, human resource and knowledge management, and the organisation of knowledge sharing within a firm on the absorptive capacity of innovative firms for three different types of knowledge, namely absorptive capacity to use knowledge from a...

This paper presents the stylized facts of open source software innovation and provides empirical evidence on the impact of increased competition by OSS on the innovative activity in the software industry. Furthermore, we introduce a simple formal model that captures the innovation impact of OSS...

The production of health does not only depend on the medical services supplied by the physi-cian but is also influenced by the patient’s compliance. A model of medical treatment is pre-sented in which both the actions of physician and patient are modeled as a productive input. The analysis...

We analyse economic welfare in R&D intensive industries under varying assumptions on the spillover process. The focus lies on spillover processes with complementary R&D investments such as those modelling absorptive capacity. There spillovers give rise to both negative and positive...

With the expiry of the Pharmaceutical Industry Investment Program (PIIP) in 2004, the Commission was asked to conduct an evaluation of the program’s rationale, effectiveness and efficiency. The study commenced in August 2002. The Commission found that this assistance scheme had significant...

What determines the speed of the technology diffusion? What are the consequences of diffusion? This paper presents a model to address these questions. Skilled machine-users adopt a new technology first, while unskilled users wait until machines become more reliable and accessible. The quality...

Empirically R&D expenditure moves pro-cyclically, but the pro- cyclicality is a puzzle from the Schumpeterian point of view. The paper examines the cyclical property of R&D expenditure in the context of endogenous growth, and concludes that (i) substitutability between investing in physical...

This paper presents a dynamic partial equilibrium model that endogenizes firms' investment decision on innovation: product innovation causes horizontal expansion growth, and process innovation causes vertical expansion growth. Market structure in different markets emerges as a consequence of...

This paper formulates dynamic R\&D investment decisions of private firms as an optimal stochastic control problem. It derives explicitly R\&D investment decision rule and the cross equations parameter restrictions imposed by the rational expectations hypothesis, using the Riccati equations only...

This paper analyzes the incentives for governments to impose export subsidies when firms invest in a cost saving technology before market competition. Governments first impose an export subsidy or a tax. After observing export policy, firms invest in cost reducing R&D and subsequently compete in...
