Who will end up without a rose on Valentine's Day?
Relative reliability for rose exporters in Kenya during post-election violence in 2008. Each point represents one buyer-seller relationship. Farms affected by violence (red points) seemed to prioritize middle-aged relationships at the expense of very new and very old relationships. The authors' hypothesis is that sellers felt their oldest relationships could better survive a one-time lapse.
