This policy note investigates whether the current level of public support to environment-friendly technologies is sufficient to allow European countries to respond to the multiple challenges posed by climate change and other environmental concerns. We first lay out the justifications for...

The paper analyzes the relationship between CO2 mitigation policy and promotion policies designed to deploy renewable energy sources for electricity production (RES-E). If an emission cap is the only policy target, an optimal mix consisting of high and low carbon use of fossil fuels, deployment...

The industrial sector is responsible for roughly one quarter of global greenhouse-gas (GHG) emissions. To align sector pathway developments with overarching net-zero transition goals in different industries, governments are required to understand sectoral reduction potentials to efficiently...

Green innovation is essential for climate change mitigation, but not all innovative projects deliver equal social value. We consider innovator heterogeneity in a model where the policy maker cannot observe innovation quality and directly subsidize the socially most valuable green innovations. We...

We build a stylized model that captures the relationships between cross-border patenting, globalization, and development. Our theory delivers a gravity equation for cross-border patents. To test the model's predictions, we compile a new dataset that tracks patents within and between countries...

This paper studies the effect of structural change on the historical path of aggregate labor productivity growth for a large sample of European countries, and it builds a quantitative multi-sector growth model to analyze the potential impact that structural change may have on future productivity...

The US decision not to ratify the Kyoto Protocol and the recent outcomes of the Bonn and Marrakech Conferences of the Parties drastically reduces the effectiveness of the Kyoto Protocol in controlling GHG emissions. The reason is not only the reduced emission abatement in the US, but also the...

An increasing body of empirical evidence is documenting trends toward rising concentration, profits, and markups in many industries around the world since the 1980s. Two major criticisms of these studies is that concentration and market shares are poorly measured at the national industry level...
