1. I coded civil wars as having had "negotiations" if factions held face-to-face talks and issues relevant to resolving the war were discussed. These qualifications eliminated scheduled talks that never took place, meetings where no substantive issues were deliberated, and talks that excluded key participants. I also attempted to apply a "good faith" proviso and exclude those meetings where one or both participants were obviously unwilling to yield on important issues. Although sometimes difficult to determine, certain actions did signal whether or not faction leaders honestly wished to cooperate. Their readiness to accept supervision, make public announcements of important concessions, discuss the details of a transfer of power, and participate in lengthy negotiations all generated costs to the groups involved and indicated more than a tactical interest in appearing to be cooperative. To say that a civil war experienced "negotiations," however, does not imply that groups would not willingly defect if they could benefit from cheating. "Negotiations" simply indicate that they were willing to consider an alternative to war.
2. Throughout this article, I treat both the government and the rebels as if leaders on each side represent a homogeneous group with unitary interests. In reality, the interests of a group are often diverse and transitory, and leaders frequently preside over fragile coalitions whose internal politics dictate behavior. Nonetheless, this assumption is justified because I argue that even if leaders are fortunate enough to preside over a group in complete agreement on behavior, they will still encounter difficult commitment problems. For an article that specifically addresses how the internal politics of a group can affect decisions to negotiate or fight, see Barbara F. Walter and Andrew Kydd, "Extremists, Uncertainty, and Commitments to Peace," unpublished paper, University of California, San Diego, or University of California, Riverside, September 1998.
