This study employed a stochastic frontier translog cost and production functions to measure the level of
allocative efficiency and it’s determinants in small-holder cocoyam production in Anambra state, Nigeria.
A multi-stage random sampling technique was used to select 120 cocoyam farmers in the state in 2005
from whom input-output data and their prices were obtained using the cost-route approach. The parameters
of the stochastic frontier cost function were estimated using the maximum likelihood method. The result of
the analysis shows that individual farm level allocative efficiency was about 65%. The study found age and
education to be negatively and significantly related to allocative efficiency at 1.0%. Farm size coefficient
also had a negative relationship with allocative efficiency and was significant at 5.0%. Fertilizer use and
credit access was significant and directly related to allocative efficiency at 5.0% as well as farm experience
at 10.0% level of probability. No significant relationship was found between allocative efficiency and
extension visit, family size and membership of cooperative societies.
