The rapid transition to a decarbonized energy economy is widely believed to hinge on the rate of cost improvements for certain clean energy technologies, in particular renewable power and energy storage. This paper adopts the classical learning-by-doing framework of Wright (1936), which predicts...

This note shows that the assumptions about the abatement technology modify the impact of the environmental taxation (both the size and the “direction”) on the long-run growth driven by human capital accumulation à la Lucas (1988), when the source of pollution is private consumption and...

Most CO2 abatement policies reduce the demand for fossil fuels and therefore their price in international markets. If these policies are not global, this price decrease raises emissions in countries without CO2 abatement policies, generating "carbon leakage". On the other hand, if the countries...

The topic of this note is issues related to R&D expenditures leading to improved technologies for reducing environmentally harmful emissions. The focus is on he following questions: Will a market economy where environmental policies are restricted to taxes or quotas give the socially efficient...

This paper refines indicators to measure innovation in environment-related technologies, drawing on recent methodological advances that allow a more accurate assessment of environment-related innovation in a broader range of countries and covering a greater variety of the relevant technologies....
