We investigate the effect of environmental policies on innovation under different levels of competition. Using information regarding renewable energy policies, competition and green patents for OECD countries since the late 1970s, we develop a pre-sample mean count-data econometric specification...

[fre] Cet article présente une méthode d'analyse statistique permettant d'étudier l'organisation des connaissances de la firme à partir de données de brevets. Nous partons de l'idée que les connaissances sont hétérogènes en ce qu'elles sont liées à des disciplines scientifiques et...

We investigate the effectiveness of policies in favor of innovation in renewable energy under different levels of competition. Using information regarding renewable energy policies, product market regulation and high-quality green patents for OECD countries since the late 1970s, we develop a...

We use comparable micro level panel data for 14 countries and a set of identically specified empirical models to investigate the relationship between exports and productivity. Our overall results are in line with the big picture that is by now familiar from the literature: Exporters are more...

We examine the relationship between the coherence of the knowledge base and the innovative performance of U.S. pharmaceutical firms during the 1990's. We develop measures of the coherence and scope of the firms' knowledge base. Count data regression models show a strong link between these two...

In this paper we intend to discuss the relationship between long term development trajectories, which in principle can be expected to affect the functioning of all economic systems, and the deviations which can be expected to occur at a local level in particular countries or regions. We will...

We develop a new methodology for evolutionary economic modelling, based upon the ‘micro-meso-macro’ analytical framework for dealing with behaviour in complex economic systems. This new methodology involves a combination of computational, historical and econometric methods. It is argued that...

This paper analyzes the effect of environmental policies on the direction of energy innovation across countries over the period 1990-2012. Our novelty is to use threshold regression models to allow for discontinuities in policy effectiveness depending on a country's relative competencies in...
