This paper provides a rationale for subsidizing green (renewable) energy production. Within a multi-country model where energy is produced with mobile capital in green and dirty production, we investigate the countries' decentralized choice of emissions taxes and green energy subsidies. Without...

Within a two-country model, this paper identifies a novel emission leakage channel that is caused by moral behavior of (atomistic) consumers. In a non-cooperative emission tax game between the countries, the leakage effect lowers the governments’ marginal benefit of emission taxation, so...

This paper analyzes the optimal level of public debt when taxes are used not only for funding public expenditures but also for correcting externalities from climate change. Taking into account externalities implies that the optimal policy deviates from tax smoothing. Provided cumulative marginal...

This note corrects an error in the analysis of Goering/Boyce (1999) and extends their results. In this way, it refutes the claim that the durability of rented products plays a decisive role for the second-best emission taxation under imperfect competition.
