We demonstrate the advantages of a climate treaty based solely on rules for international permit markets when there is uncertainty about abatement costs and environmental damages. Such a ‘Rules Treaty’ comprises a scaling factor and a refunding rule. Each signatory can freely choose the...

In this paper we show that both climate models and economic models studying the effects of climate change are characterized by high uncertainty. Hence, far reaching policy implications such as the net zero goal lack a definite scientific foundation. Neverthelss, it cannot be excluded that the...

The general equilibrium model developed by Golosov et al. (2014), GHKT for short, is modified to allow for additional negative impacts of global warming on utility and productivity growth, mean reversion in the ratio of climate damages to production, labour-augmenting technical progress, and...

The IPCC Special Report finds that current policies are not sufficient to limit global warming to well below 1.5°C, and that the gap between the actions on the ground and the required changes in order to meet the global goal is widening rapidly. One reason is that scientific assessments based...

The European Union's Emissions Trading System is the largest system in the world for trade in greenhouse gases. It used to be a cap-and-trade scheme with a fixed supply of permits. However, a recent reform of the system "punctures the waterbed" by making the supply of permits endogenous. The...
