According to the Phase IV (2021-2030) rules of the EU ETS, the total amount of emissions permits allocated to firms is not fixed but endogenous. This implies that a national climate policy that overlaps with the emission trading system can have an impact on total aggregate emissions. Roughly...

We study the impact of a one-off exogenous fiscal windfall on local public finances in the canton of Zurich in Switzerland. The windfall was due to the IPO of Glencore on the London Stock Exchange in 2011. As a result, its CEO paid an extraordinary tax bill of approximately CHF 360 million....

A two-tier climate club exploits the comparative advantage of large countries to mete out punishments through trade, while taking their capacity to resist punishment as a constraint. Countries outside the coalition price carbon at a fixed fraction of the average carbon price adopted within the...

This paper studies the implications of energy prices today for energy efficiency and climate policy in the future. If adjustment costs mediate manufacturing plants’ responses to increases in energy prices, incumbents may be limited in their ability to re-optimize energy-inefficient production...

People who anticipate the introduction of a policy can adapt their behavior, perhaps in ways that make the policy ineffective and exacerbate the problem to be addressed. This paper develops a political economy model to study strategic behavior related to the introduction of congestion policies,...

Linkage of cap-and-trade systems is typically advocated by economists on a general analogy with the beneficial linking of free-trade areas and on the specific grounds that linkage will ensure cost effectiveness among the linked jurisdictions. An appropriate and widely accepted specification for...

This paper presents a novel benefit of linking emission permit markets. We let countries issue permits non-cooperatively, and with endogenous technology we show there are gains from permit trade even if countries are identical. Linking the permit markets of different countries will turn permit...

“Prices versus quantities” (Weitzman 1974), a hugely influential paper, is widely cited (and taught) in current debates about the best policy to reduce greenhouse gas emissions. The paper’s criterion for ranking policies suggests that technological uncertainty favors taxes over cap and...

The general equilibrium model developed by Golosov et al. (2014), GHKT for short, is modified to allow for additional negative impacts of global warming on utility and productivity growth, mean reversion in the ratio of climate damages to production, labour-augmenting technical progress, and...

We analyse optimal abatement and carbon pricing strategies under a variety of economic, temperature and damage risks. Economic growth, convex damages and temperature-dependent risks of climatic tipping points lead to higher growth rates of carbon prices, but gradual resolution of uncertainty...
