A two-tier climate club exploits the comparative advantage of large countries to mete out punishments through trade, while taking their capacity to resist punishment as a constraint. Countries outside the coalition price carbon at a fixed fraction of the average carbon price adopted within the...

The paper proposes an agreement structure that extends Nordhaus's (2015) climate club by adding a second tier. Countries outside the coalition are required to price carbon at a fixed fraction of the average carbon price adopted within the coalition, or face tariffs. Coalition countries abate...

Slowing global warming requires countries to reduce carbon emissions, which imposes costs on their economies. To be effective, most countries must agree collectively to participate (e.g., the Paris Agreement, COP26). However, every country has an incentive not to comply and still reap the...

We explore a global carbon pricing framework to inform the potential coordination of carbon pricing and equivalent policies. The framework has three main features aligning with the current multilateral system for climate action. First, the carbon price is determined by a global average carbon...

This paper studies a dynamic stochastic general equilibrium model involving climate change. Our model allows for damages on economic growth resulting from global warming. In the calibration, we capture effects from climate change and feedback effects on the temperature dynamics. We solve for the...

This paper studies a dynamic stochastic general equilibrium model involving climate change. Our frame- work allows for feedback effects on the temperature dynamics. We are able to match estimates of future temperature distributions provided in the fifth assessment report of the IPCC (2014). We...

The Nationally Determined Contributions (NDCs) under the Paris Agreement fall short of the abatement needed to reach the 2°C target. Emissions trading could be a "costless" means to reduce the ambition gap if countries used their gains from trade for additional abatement. However, this requires...

The present paper analyzes the impact of a climate coalition's border carbon adjustment on emissions from commodity production, welfare and the coalition size. The coalition implements border carbon adjustment to reduce carbon leakage and to improve its terms of trade, while the fringe abstains...

Global public goods pose great risks, especially when the lack of these goods may have devastating consequences. Climate protection is such a good and it faces a triple dilemma: the so-called Westphalian dilemma of sovereign nation states, a weakest-link dilemma as the success of climate...
