The last few years have witnessed important advances in our understanding of time preference and social discounting. In particular, several rationales for the use of time-varying social discount rates have emerged. These rationales range from the ad hoc to the formal, with some founded solely in...

Research into the social cost of carbon emissions — the marginal social damage from a ton of emitted carbon — has tended to focus on “best guess” scenarios. Such scenarios generally ignore the potential for low-probability, high-damage events, which are critically important to...

The paper sets out the credibility problem in carbon policy, provides a number of examples of non-credibility in recent energy policy, and identifies the costs of failing to address it. The time inconsistency of carbon policy--arising because of multiple objectives, the irreversibility of energy...

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 book sets out the building blocks of an economic approach to biodiversity, and in particular brings together conceptual and empirical work on valuation, international agreements, the policy instruments, and the institutions. The objective is to provide a comprehensive overview of the issues...

Conventional benefit-cost analysis incorporates the normally reasonable assumption that the policy or project under examination is marginal. In particular, it is assumed that the policy or project does not change the underlying growth rate of the economy. However, this assumption may be...

This article examines the issue of whether low-carbon growth might be in the self-interest of Brazil, India, and China. These countries are the largest member countries of the G20 emerging markets (GEMs), and are also members of the BRIC and BASIC grouping of countries. Individually, they are...

This article suggests that some or all G-20 Emerging Markets (GEMs = Argentina, Brazil, China, India, Indonesia, Korea, Mexico, South Africa, and Turkey) could seize the climate policy agenda and open up these broader opportunities with a coordinated, self-interested announcement to exploit the...
