In this paper we study two closely related issues. First, the role of technology heterogeneity and diffusion in the convergence of GDP per worker observed across the European regions, in the absence of data on regional TFP. Second, the spatial pattern of the observed regional heterogeneity in...

The aim of this paper is to estimate the effect of research externalities across space, in generating innovation. We do so by using R&D and patent data for eighty-six European Regions in the 1977-1995 period. We find that spillovers exist for regions within a distance of 300 Km from each other....

Carbon Capture Utilization and Storage (CCUS) stands as a pivotal technology crucial for achieving the most ambitious climate objectives. Despite its prominent inclusion in energy mix projections, its current deployment falls short of the requisite level. Additionally, uncertainties surrounding...

We determine the core characteristics of a climate coalition's optimal policies in a dynamic two country directed technical change framework. Unilateral policies alter the structure of production and thereby innovation incentives across countries. Whenever feasible, optimal policies implement...
