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...

Global cap and trade equalizes the price of emissions and leads to efficient abatement across countries, but sets the abatement level inefficiently low. It is set too low, because the global cap is the sum of individual country targets set on the basis of self-interest. The efficiency of a...

The international game of cap and trade begins when countries choose their quantity targets, which are largely selected according to self interest. The analogous public-goods game, in which countries choose their abatement levels, has an uncooperative outcome. Compared to that, the Nash...

Developing countries justifiably reject meaningful emission targets. This prevents the Kyoto Protocol from establishing a global price for greenhouse gas emissions, and leaves almost all new emissions unpriced. This paper proposes a new pair of commitments—a commitment to a binding...

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...

A forward reliability market is presented. The market coordinates new entry through the forward procurement of reliability options—physical capacity bundled with a financial option to supply energy above a strike price. The market assures adequate generating resources and prices capacity from...

Wholesale electricity markets are commonly organized around a spot energy market. Buyers and suppliers submit bids and offers for each hour and the market is cleared at the price that balances supply and demand. Buyers with bids above the clearing price pay that price, and suppliers with offers...

We argue that a capacity market is needed in most restructured electricity markets, and present a design that avoids the many problems found in the early capacity markets. The proposed locational capacity market pays suppliers based on their demonstrated ability to supply energy or reserves in...

A firm energy market for Colombia is presented. Firm energy—the ability to provide energy in a dry period—is the product needed for reliability in Colombia’s hydro-dominated electricity market. The firm energy market coordinates investment in new resources to assure that sufficient firm...
