This paper formalizes the geopolitical externality of climate policy and estimates its plausible magnitudes. Specifically, domestic reductions in fossil fuel demand depress global prices, thereby lowering export revenues for resource-rich autocracies - many of which allocate substantial...

Carbon tariffs are one prominently discussed climate policy. The proponents stress the carbon tariffs' ability to restore competitiveness, avoid carbon leakage, and reduce world carbon emissions. We analyze the effects of carbon tariffs on trade, welfare, and carbon emissions in a structural...

Unilateral climate policy suffers from carbon leakage, i.e. the (partial) offset of the initial emission reduction by increases in other countries. Different than most typically discussed climate policies, degrowth not only aims at reducing the fossil fuel use in an economy, but rather at a...

The European Union (EU) is implementing a Carbon Border Adjustment Mechanism (CBAM) at its borders, which will require exporters of basic materials to surrender emission permits when exporting to the EU market. Since it makes foreign producers compete under a carbon price, the EU CBAM may...

Carbon tariffs are one prominently discussed environmental policy. The proponents stress the carbon tariffs' ability to mitigate the potential negative effect of environmental-friendly production on competitiveness, to avoid carbon leakage and to reduce world carbon emissions. We analyze the...

In this paper we investigate the introduction of an export tax on steam coal levied by an individual country (Australia), or a group of major exporting countries. The policy motivation would be twofold: generating tax revenues against the background of improved terms-of-trade, while CO2...
