This paper studies the impact of cross-border Mergers and Acquisitions (M&As) on Carbon Dioxide emissions. Carbon Dioxide is the main anthropogenic greenhouse gas. A global problem that requires a multilateral solution. To take this into account we introduce an institutional variable, which...

This paper offers a new methodology to identify R&D and innovation clusters, on the basis of a regional analysis of innovation support systems in Portugal. Using a web-based inventory of R&D and innovation agencies, an extensive data base is created. This data set is next analyzed by means of...

This discussion paper resulted in a publication in 'Industry and Innovation', 2011, 18(3), 317-334.<P> This article presents a model of sequential decisions about investments in environmentally dirty and clean technologies, which extends the path-dependence framework of Arthur (1989). This allows...</p>

This survey reviews the empirical literature on the impact of environmental policy instruments on the rate and direction of technological change. The survey is explicitly focused on the empirical identification of the hypothesis to expect a stronger impact from market-based incentives than from...

We address the notion of dynamic, endogenous diversity and its role in theories of investment and technological innovation. We develop a formal model of an innovation arising from the combination of two existing modules with the objective to optimize the net benefits of diversity. The model...

This article presents a model of sequential decisions about investments in environmentally dirty and clean technologies, which extends the path-dependence framework of Arthur (1989). This allows us to evaluate if and how an economy locked into a dirty technology can be unlocked and move towards...

We argue that expectations about future energy use affect the transition from fossil fuels to renewable substitutes, because of an interaction between innovation and resource scarcity. The paper presents a model of directed technical change to study this interaction. We find that resource-saving...
