Research on HIV infection and sexual behaviour in sub-Saharan Africa typically focuses on individuals aged 15–49 years, under the assumption that both become less relevant for older individuals. We test this assumption using data from rural Malawi to compare sexual behaviour and HIV infection...

There is an increasing demand for putting a shadow price on the environment to guide public policy and incentivise private behaviour. In practice, setting that price can be extremely difficult as uncertainties abound. There is often uncertainty not just about individual parameters but about the...

At present the USA is - in per capita terms - the top greenhouse gas polluter among the world’s major economies. This is mirrored by the high energy intensity of all sectors of the US economy including manufacturing industries. A potential explanation for the higher energy intensity is lower...

This paper considers how environmental policies should respond to macroeconomic downturns. It first explores the implications of the global economic downturn of 2008-09 for environmental policies, focusing in particular on the example of action against climate change. The arguments for and...

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...

Economic evaluation of climate policy traditionally treats uncertainty by appealing to expected utility theory. Yet our knowledge of the impacts of climate policy may not be of sufficient quality to justify probabilistic beliefs. In such circumstances, it has been argued that the axioms of...

Climate change is likely to lead to an increase in the frequency and/or intensity of certain types of natural hazards, if not globally, then at least in certain regions. All other things equal, this should lead to an increase in the economic toll from natural disasters over time. Yet, all other...

As the world becomes wealthier over time, inflation-adjusted insured damages from natural disasters go up as well. This article analyzes whether there is still a significant upward trend once insured natural disaster loss has been normalized. By scaling up loss from past disasters, normalization...

Deforestation and forest degradation are some of the main contributors to anthropogenic climate change. Accordingly, policies to arrest deforestation or increase forest areas are proposed as important forms of climate change policy. This paper summarizes current proposals for addressing the...
