Peace agreement design and public support for peace: Evidence from Colombia

Conflict negotiations are often met with backlash in the public sphere. A substantial literature has explored why civilians support or oppose peace agreements in general. Yet, the terms underlying peace agreements are often absent in this literature, even though (a) settlement negotiators must craft agreement provisions covering a host of issues that are complex, multidimensional, and vary across conflicts, and (b) civilian support is likely to vary depending on what peace agreements look like. As a result, we know much less about how settlement design molds overall public response, which settlement provisions are more or less controversial, or what citizens prioritize in conflict termination. In this article, I identify four key types of peace agreement provisions and derive expectations for how they might shape civilian attitudes toward conflict termination. Using novel conjoint experiments fielded during the Colombian peace process, I find evidence that citizens evaluate agreements based primarily on how provisions mete out justice to out-group combatants, and further that transitional justice provisions produced sharp divisions among urban voters in the 2016 referendum. Additional analysis suggests that material, distributive concerns were particularly salient for rural citizens. The results have implications for understanding the challenge of generating public buy-in for conflict termination and sheds light on the polarizing Colombian peace process.
