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...

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...

By the early 1990s, employee stock ownership plans (ESOPs) had become as prevalent in unionized firms as in nonunionized firms. However, little research has been devoted to examining the implications of ESOPs for collective bargaining or, more generally, for cross ownership. In this paper, we...

Spectrum auctions are used by governments to assign and price licenses for wireless communications. Effective auction design recognizes the importance of competition, not only in the auction, but in the downstream market for wireless communications. This paper examines several instruments...

A proposed auction design for incentive auctions is given. The two-sided auctions enable the exchange of spectrum from a low-value use, such as over-the-air TV broadcast, to a high-value use, such as mobile broadband. The approach is both simple and effective. The auction has three stages...

Spectrum auctions are used by governments to assign and price licenses for wireless communications. The standard approach is the simultaneous ascending auction, in which many related lots are auctioned simultaneously in a sequence of rounds. I analyze the strengths and weaknesses of the approach...

A central question in economics is understanding the difficulties that parties have in reaching mutually beneficial agreements. Informational differences provide an appealing explanation for bargaining inefficiencies. This chapter provides an overview of the theoretical and empirical literature...
