This paper uses the WITCH model, a computable general equilibrium model with endogenous technological change, to explore the impact of various climate policies on energy technology choices and the costs of stabilising greenhouse gas concentrations. Current and future expected carbon prices...

We argue that the intrinsic inefficiency of proprietary software has historically created a space for alternative institutions that provide software as a public good. We discuss several sources of such inefficiency, focusing on one that has not been described in the literature: the...

'National Innovation Systems' theories are built upon the assumption that linkages among organisations matter to innovation. Specifically, proximity is a crucial factor in most of the explanations of regional innovation systems. Yet several thing, such as the rapid growth of the internet and...

This empirical paper investigates the impact of different sources of increasing returns on firm innovative behaviour in different regions of the UK. Of the different sources of increasing returns, the impact of intermediation and the emergence of specialised markets on the probability of...

The stabilisation of GHG atmospheric concentrations at levels expected to prevent dangerous climate change has become an important, global, long-term objective. It is therefore crucial to identify a cost-effective way to achieve this objective. In this paper we use WITCH, a hybrid...

As an introduction to a series of contributions about Internet economics, the present paper has three goals. We firstly recall several basic facts and principles characterizing the morphology of the Internet, its operating system, its regulation procedures, as well as its rapid success which...

While the cumulative nature of knowledge is recognized as central to economic growth, the microeconomic foundations of cumulativeness are less understood. This paper investigates the impact of a research-enhancing institution on cumulativeness, highlighting two effects. First, a selection effect...

This paper addresses two basic issues related to technological innovation and climate stabilisation objectives: i) Can innovation policies be effective in stabilising greenhouse gas concentrations? ii) To what extent can innovation policies complement carbon pricing (taxes or permit trading) and...

This paper presents an empirical analysis of the determinants of research cooperation between firms and Public Research Organisations (PROs) for a sample of innovating small and mediumsized enterprises. The econometric analysis is based on the results of the KNOW survey carried out in seven EU...
