The chair is pleased to announce that the publication by Prof. Dr. Jan Krämer, Prof. Dr. Karl-Martin Ehrhart (KIT) and Dr. Christian Feige entitled „Climate Negotiations in the Lab: A Threshold Public Goods Game with Heterogeneous Contributions Costs and Non-binding Voting“  has been accepted for publication in the journal Environmental and Resource Economics. The 2015 ISI Impact Factor for Environmental and Resource Economics is 1.667.

Abstract:
"We model the climate negotiations and the countries’ individual commitments to carbon dioxide reductions as a threshold public goods game with uncertain threshold value. We find that a non-binding unanimous voting procedure on contribution vectors leads to frequent agreement on an optimal total contribution and high rates of compliance, even in the case of heterogeneous marginal contribution costs. However, groups that do not reach agreement perform worse than the baseline treatments without a voting procedure. The contribution vectors chosen by the groups point to a predominant burden-sharing rule that equalizes individual contribution costs, even at the cost of the group’s total payoff."
