This document summarizes a study on the coffee distribution system in Addis Ababa, Ethiopia. The study examines three research questions: 1) Can traders be trusted regarding quality and weights? 2) Is quality control effective? 3) Do markets reward quality? The study finds that while traders can generally be trusted with weights, some cheat on unobservable quality indicators. Quality control is ineffective as an informal market has developed. Markets reward observable quality factors like washing and packaging but not origins. The implications are that controlling markets may not be useful given circumvention, and consumer protection is difficult in informal systems but may not be needed for observable quality factors.
