We distinguish between local problems of biodiversity loss and global ones, where international cooperation is required. Global biodiversity regulation involves choosing the optimal stopping rule regarding global land conversions, in order to ensure that some areas of unconverted natural...

While the global economy continues to grow, ecosystem services tend to stagnate or decline. Economic theory has shown how such shifts in relative scarcities can be reflected in project appraisal and accounting, but empirical evidence has been sparse to put theory into practice. To estimate...

We assess how changes in the scientific consensus around equilibrium climate sensitivity (ECS), as captured by the IPCC’s Fifth (AR5) and Sixth (AR6) Assessment Reports, impact policymakers’ willingness to take climate action. Taking the IPCC’s reports at face value, the ECS estimates in...

We exploit a unique panel of 75 metro areas (‘cities') across the globe and employ a city-fixed effects model to identify the determinants of within-city changes in air pollution concentration between 2005 and 2011. Increasing car and population densities significantly reduce air pollution...

In many developing countries, decentralization programmes for natural resource management aim to induce incentives for sustainable resource management at the local level. The effectiveness of such programmes has, however, suffered from weak property rights to the resource and by the presence of...
