Two reasons to be concerned about climate change are its unjust distributional impact and its negative aggregate effect on economic growth and welfare. Although our knowledge of the impact of climate change is incomplete and uncertain, economic valuation is difficult and controversial, and the...

Water problems are typically studied at the farm-level, the river–catchment-level or the country-level. About 70% of irrigation water is used for agriculture, and agricultural products are traded internationally. A full understanding of water use is impossible without understanding the...

Tol (2003) found evidence that the uncertainty that surrounds estimates of the marginal damage of climate change may be infinite even if total damages are finite and questioned the applicability of expected cost-benefit analysis to global mitigation policy. Yohe (2003) suggested that this...

Terrestrial sinks have entered the Kyoto Protocol as offsets for carbon sequestration, but ocean sinks have escaped attention. Ocean sinks are as unexplored and uncertain as were the terrestrial sinks at the time of negotiation. It is not unlikely that certain countries will advocate the...

Using a simple model designed for transparency but nonetheless calibrated to support the much-quoted damage estimates of the Stern Review of the Economics of Climate Change, we demonstrate significant sensitivity of those results to assumptions about the pure rate of time preference, the...

We present the Canberra-Hamburg Integrated Model for Population (CHIMP), a new global population model for long-term projections. Distinguishing features of this model, compared to other model for secular population projections, are that (a) mortality, fertility, and migration are partly driven...

Global Warming Potentials (GWPs) are evaluated as proxies of the historical temperature by applying them to convert historical CH4 and N2O emissions to equivalent CO2 emissions. Our GWP analysis is based on the historical Earth system evolution obtained from the inverse calculation for the...

This paper studies the economic implications of climate-change-induced variations in tourism demand, using a world CGE model. The model is first re-calibrated at some future years, obtaining hypothetical benchmark equilibria, which are subsequently perturbed by shocks, simulating the effects of...

We analyse the destination choice of Chinese tourists in China and abroad. Abroad, Chinese tourists prefer to travel to large and rich countries, and are little deterred by distance. Climate, coast, culture and political stability are irrelevant. Chinese tourists travel disproportionally to...
