Larry Solum has a great post entitled Game Theory & the Prisoner's Dilemma. As Larry explains:
One of the most useful tools in analyzing legal rules and the policy problems to which they apply is game theory. The basic idea of game theory is simple. Many human interactions can be modeled as games. To use game theory, we build a simple model of a real world situations as a game. Thus, we might model civil litigation as a game played by plaintiffs against defendants. Or we might model the confirmation of federal judges by the Senate as a game played by Democrats and Republicans. This week's installment of the Legal Theory Lexicon discusses one important example of game theory, the prisoner's dilemma.I used the prisoner's dilemma to model the behavior of sovereign debtors vis-a-vis creditors in my article Comity and Sovereign Debt Litigation: A Bankruptcy Analogy:
Abstract: On repeated occasions in the post-war period, the cumulative effects of policy mistakes, recessions, inflation, and other economic problems have made it difficult for sovereign debtors to service their external debt. Unlike a domestic U.S. private debtor, who may resort to formal bankruptcy procedures in the event of insolvency, a defaulting sovereign debtor has no formal mechanism for triggering a restructuring of its debt.
In some cases, sovereign debtors have resorted to a moratorium on debt payments. This article argues that U.S. courts ought to give effect to such moratoria under the international law principle of comity. Using standard game theory methodology (the so-called "creditors dilemma" variant of the famous "prisoners dilemma"), the article argues that creditors of such debtors would agree in advance to give effect to such a moratorium provided it neither repudiated the sovereign's debts not gave preference to certain creditors. A legal test for granting comity to sovereign debt moratoria is therefore proposed.
