We analyse how the joint adoption of ICT practices and environmental innovation affect the labour productivity of firms. We study complementarity in innovation adoption, with respect to the specific research hypotheses that the higher thediffusion and radicalness of ICT and EI, the higher might...

The adoption and diffusion of environmental innovations (EIs) is crucial to greening the economy and achieving win-win environmental-economic gains. A large and increasing literature has focused on the levers underlying EIs that are external to the firm, such as stakeholders' pressure and policy...

The paper investigates the effectiveness and efficiency of energy-environmental policy interactions in Italy, adopting a broad optimality perspective that includes policy feasibility and dynamic efficiency. The analysis highlights that though some complementarity among different policies exists,...

This paper revisits the Porter hypothesis by pursuing two new directions. First, we compare the results obtained with two complementary approaches: parametric stochastic frontier analysis and conditional nonparametric frontier analysis. They presents relative advantages and drawbacks. Secondly,...

This paper provides an econometric examination of geographic R&D spillovers among countries by focusing on the issue of cross-sectional dependence, and in particular on the different ways – weak and strong – it may affect the model. A preliminary analysis based on the estimation of the...

We study long run carbon dioxide emissions-economic development relationships for advanced countries grouped in policy relevant groups: North America and Oceania, South Europe, North Europe. By relying on recent advances on Generalized Additive Mixed Models (GAMMs) and adopting interaction...

By adopting a semiparametric approach, the 'traditional' regional knowledge production function is developed in three complementary directions. First, the model is augmented with region-specic time trends in order to account for endogeneity due to selection on unobservables. Second, the...
