Strategic patenting is widely believed to raise the costs of innovating, especially in industries characterised by cumulative innovation. This paper studies the effects of strategic patenting on R&D, patenting and market value in the computer software industry. We focus on two key aspects:...

We develop a model of two-stage cumulative research and development (R&D), in which one Research Unit (RU) with an innovative idea bargains to license her nonverifiable interim knowledge exclusively to one of two competing Development Units (DUs) via one of two alternative modes: an Open sale...

The paper examines recent evidence on the erosion of the German industrial relations model. Although its coverage has declined, much of this has occurred in smaller and newer establishments, and compared with Britain, it has remained solid in the areas of Germany's traditional industrial...

The erosion of a number of national systems of employment relations, and the evidence fromlarge scale workplace surveys has brought attention to the considerable diversity ofemployment systems within major economies. This essay applies the theory of evolutionarygames to explain the diffusion of...

The emergence of the so-called ‘network economy’ and the development of project-based work pose a fundamental challenge to established methods of regulating the employment relationship. There appears to be an unsatisfied demand for its greater use, especially among employers, and it is...

Cumulative innovation is central to economic growth. Do patent rights facilitate or impede such follow-on innovation? This paper studies the effect of removing patent protection through court invalidation on the subsequent research related to the focal patent, as measured by later citations. We...

This paper presents the first empirical analysis of programmes to fast-track ‘green’ patent applications in place in seven Intellectual Property offices around the world. We find that only a small share of green patent applications (between 1% and 20% depending on the patent office) request...
