We analyse the effects of a price floor on price wars in the retail market for gasoline. Our theoretical model assumes a Bertrand oligopoly supergame in which firms initially collude by charging the monopolistic price. Once firms detect a deviation from this strategy, they switch to a lower...

We argue for the creation of a carbon liabilities market to address climate change. Each period, countries would be made liable for their share of responsibility in current climate damage. Because liabilities could be traded like financial debt, robustness to strategic manipulations and...

Due to meteorological factors, the distribution of the environmental damage due to climate change bears no relationship to that of global emissions. We argue in favor of offsetting this discrepancy, and propose a global insurance scheme to be financed according to countries' responsibility for...

We observe that a Pigovian climate policy need not exact full payment of the social cost of carbon upon emission to yield optimal incentives. Following this insight, we propose the creation of a carbon liabilities market to address climate change. Each period, countries would be made liable for...
