The Polluter Pays, Then Receives (PPTR) principle claims that, had an agent innocently benefited from climate change, it owes moral obligations to the polluters who contributed to a warmer globe. This critical review assesses the evidence, the externalities argument, and the luck egalitarian...

We introduce the concept of negative extremal transfers (NETs), which are transfers from the poorest individuals to the richest individuals. This family of transfers alone is rich enough to describe the entire space of income distributions: our first result is that any income distribution can be...

Arctic oil extraction is inconsistent with the 2°C target. We study unilateral strategies by climate-concerned Arctic countries to deter extraction by others. Contradicting common theoretical assumptions about climate-change mitigation, our setting is one where countries may fundamentally...

We envision the creation of a climate liability market to address climate change. Each period, countries would be made liable for their past responsibility in current climate damage. We show that this yields the same first-best incentives to reduce emissions as a Pigovian tax. Also, because...

The management of natural commons is typically subject to threshold effects: past a certain agregate consumption level, the benefits of the commons will be lost for everybody. As dealing with the global climate illustrates, moreover, it is often impossible to locate an actual threshold with...
