The document discusses a study on trust in agricultural traders in Ethiopia's coffee market. The study examined whether traders cheat on quality and weights (Question 1) and whether regulation is effective (Question 2). It also compared traditional and modern retail practices (Question 3). The study found that traditional traders can generally be trusted for weights but cheat on hard-to-observe quality indicators. Regulation is ineffective as an illegal market flourishes. Modern markets deliver higher quality at higher prices but are not more trustworthy, cheating also on hard-to-observe quality. The implications are that markets cannot be fully trusted without adapted institutions, liberalization may be considered but not completely, and modern markets show heterogeneity.
