Conventional cost-benefit analysis incorporates the normally reasonable assumption that the policy or project under examination is marginal in the sense that it will not significantly change relative prices. In particular, it is assumed that the policy or project does not change the underlying...

Putting a price on carbon is critical for climate change policy. Increasingly, policymakers combine multiple policy tools to achieve this, for example by complementing cap-and-trade schemes with a carbon tax, or with a feed-in tariff. Often, the motivation for doing so is to limit undesirable...

This paper analyses the design of carbon markets in space (i.e., geographically). It is part of a twin set of papers that, starting from first principles, ask what an optimal global carbon market would look like by around 2030. Our focus is on firm-level cap-and-trade systems, although much of...

This paper analyses the design of carbon markets in time (i.e., intertemporally). It is part of a twin set of papers that ask, starting from first principles, what an optimal global carbon market would look like by around 2030. Our focus is on firm-level cap-and-trade systems, although much of...

Schelling (1995) stressed the importance of correctly disaggregating the impacts of climate change to understand how individual interests differ across space and time. This paper considers equity implications at a level of disaggregation which we consider insightful, but which is non-standard in...

This paper analyses the design of carbon markets in time (intertemporally) and space (geographically) from first principles, starting initially with a relatively clean slate and asking what an optimal global carbon market would look like by around 2030. Our focus is on firmlevel trading systems,...
