If a coalition of countries implements climate policies, nonparticipants tend to consume more, pollute more, and invest too little in renewable energy sources. In response, the coalition's equilibrium policy distorts trade and is not time-consistent. This paper derives conditions for when...

Free trade often leads to resource depletion, such as deforestation in the tropics. This paper first presents a dynamic model whereby the South (S) depletes to export the extracted units (lumber) or the produce (beef) from land available after depletion. Because of the damages, the North...

Every government that controls an exhaustible resource must decide whether to exploit it or to conserve and thereby let the subsequent government decide whether to exploit or conserve. This paper develops a theory of this situation and shows when a small probability that some future government...

Real-world negotiations differ fundamentally from existing bargaining theory. Inspired by the Paris Agreement on climate change, this paper develops a novel bargaining game in which each party quanti.es its own contribution (to a public good, for example), before the set of pledges must be...
