This paper looks into the economic analysis of coffee certification scheme in Ethiopia.rnThe study examines and compares per hectare productivity difference betweenrnfarmers growing organic/ fair trade certified coffee and conventional coffee.rnHousehold survey data, conducted in four kebeles at Bullie Horra district targetingrnKillenso Mokkonisa coffee farmers' cooperative, are reported and analyzed usingrninstrumental variables (two-stage least squares) regression and standard linearrndifference-in-difference econometric model. In the analysis we find that, controllingrnfor a range of factors, there likely are positive productivity effects per hectare for therntreatment group but not for the control group owing to the scheme of coffee certification. rnThis study will have policy implications on how best to design programs to link coffee rnfarmers with the international markets
