Greenhouse gas abatement is a public good, so climate policy is a public-goods game and suffers from the free-rider incentives that make the outcome of such games notoriously uncooperative. Adopting an international agreement can change the nature of the game, reducing or exacerbating the...

Developing countries reject meaningful emission targets (recent intensity caps are no exception), while many industrialized countries insist that developing countries accept them. This impasse has prevented the Kyoto Protocol from establishing a global price for greenhouse gas emissions. This...

The Kyoto summit initiated an international game of cap and trade. Unlike a national policy, the essence of this game is the self-selection of national emission targets. This differs from the standard global public-goods game because targets are met in the context of a global carbon market. This...

Displacing gasoline with a new source of biofuel, as California’s low-carbon fuel standard proposes to do, will reduce the global demand for oil. This will reduce the world oil price, which will cause an increase in oil use outside of California - the global rebound effect. Conventional wisdom...

This paper solves the global cap-and-trade game exactly as the public-goods game is normally solved and finds a problematic outcome. Abatement of greenhouse gas emissions is a global public good, and supplying a public good is a game with strong incentives to free ride. Adding a cap-and-trade...
