Free riding and coordination difficulties are held to be the primary causes of cooperation breakdown among nonrelatives. These thwarting effects are particularly severe in the absence of effective monitoring institutions capable of sanctioning deviant behavior. Unfortunately, solutions to global...

According to the Framework Convention on Climate Change, global collective action is needed to stabilize “greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous [our emphasis] anthropogenic interference with the climate system.” The Framework Convention thus...

Previous research shows that collective action to avoid a catastrophic threshold, such as a climate "tipping point," is unaffected by uncertainty about the impact of crossing the threshold but that collective action collapses if the location of the threshold is uncertain. Theory suggests that...

We experimentally test a theoretically promising amendment to the ratchet-up mechanism of the Paris Agreement. The ratchet-up mechanism prescribes that parties' commitments to the global response to climate change cannot decrease over time and our results confirm that its effect is detrimental....
