The Surprising Science of Cease-Fires: Even Failures Can Help Peace -1New York Times


No one expects the current ceasefire in Syria to last very long or provide a long-term solution to the conflict. However this article suggests that ceasefires agreements like the present one are still important:

  • “One of the best predictors of a peace agreement’s success is simply whether the parties had prior agreements, even if those earlier cease-fires failed. Not even a war’s duration or its intensity can so reliably predict a peace deal’s outcome. Neither does the poverty or ethnic diversity of the combatants.”

Ceasefires, even if they don’t last can create what the article refers to as “virtuous cycles”, wherein the parties build a degree of trust by making reciprocal concessions. If transgressions are also punished, they also learn that cheating on agreements is counter-productive. Together, these two dynamics shape the preferences of the parties making a lasting settlement more likely.

Of course, if handled poorly, the opposite lessons may be learned. If defection is widespread and inconsistently punished, then the parties learn that cooperation does not pay and cheating may actually pay-off. This result can be thought of as a “vicious cycle”.

Two points come to my while reading this article. First, the logic is very consistent with rational choice/game theory. The parties are rational actors responding to the contingencies in their environment and playing iterated games is extremely important. Second, There may be some issues with causality here. Perhaps settlements are not more likely because there are more ceasefire agreements, but instead ceasefire agreements are more likely because the conflict is winding down. If this argument is true, then it is the wider conditions in the conflict that are driving events, including the number of ceasefires and whether or not they create virtuous cycles or viscous cycles.
