Economists often regard broad-based carbon pricing (whether in the form of a carbon tax or cap and trade) as the most efficient policy to reduce carbon dioxide emissions. Relative to a narrower policy that exempts some emissions sources, a broader policy is often favored because it can exploit...

We critically review the Kyoto Protocol and thirteen alternative policy architectures for addressing the threat of global climate change. We employ six criteria to evaluate the policy proposals: environmental outcome, dynamic efficiency, cost effectiveness, equity, flexibility in the presence of...

That climate policies are costly is evident and therefore often creates major fears. But the alternative (no action) also has a cost. Mitigation costs and damages incurred depend on what the climate policies are; moreover, they are substitutes. This brings climate policies naturally in the realm...

This paper uses analytical and numerical general equilibrium models to study the costs of achieving pollution reductions under a range of environmental policy instruments in a second-best setting with pre-existing factor taxes. We compare the costs and efficiency impacts of emissions taxes,...

This paper examines the optimal setting of environmental taxes in economies where other, distortionary taxes are present. We employ analytical and numerical models to explore the degree to which, in a second best economy, optimal environmental tax rates differ from the rates implied by the...
