摘要：This paper investigates the components of farm-level total factor productivity (TFP) and examines the role of mix efficiency in integrated crop-livestock systems in Ghana. A FärePrimont productivity index is estimated and decomposed into various efficiency components. The result suggests that, mix inefficiency is consistently greater than technical and scale inefficiency. However, input-mix inefficiency was found to be higher than output mix inefficiency which suggests that crop-livestock farmers are relatively able to obtain gains in productivity from altering their output mixes more than altering input mixes. Future research and development efforts on mix efficiency in crop-livestock farming and agriculture in general need to take account of examining input-mix inefficiency. Strategies to improve productive efficiency in the Ghanaian agriculture should also emphasize improvements in mix efficiency such as policies that induce farmers to alter their input and output mixes.
