International climate negotiations have so far failed to produce ambitious climate cooperation. We combine laboratory experiments with simulations to investigate the performance of two negotiation design features to address this failure: The Paris Agreement's ratchet-up mechanism, which requires...

The EU steps up its efforts to curb its territorial CO2-emissions. It is planning to introduce a carbon border adjustment mechanism (CBAM) to level the playing field and to raise own resources. However, unilateral European climate policy action, whether shored up with a CBAM or not, can only...

International cooperation on the reduction of greenhouse gas emissions, disarmament, or free trade needs to be negotiated. The success of such negotiations depends on how they are designed. In the context of international climate change policy, it has been proposed [e.g., Weitzman J of the...

A sustainable socio-economic development requires the global reduction of CO2 emissions. We utilize an incentivized experiment to map the preferences of ‘policymakers’ over climate actions of ‘decision-makers’. Importantly, our design guarantees that these preferences are unaffected by...
