For a small developing country that pursued trade openness policies over three decades, what are the effects of trade openness on technical efficiency in agriculture, a sector that contributes significantly to the economy through employment and GDP? The study estimated the technical efficiency of Ghana’s agriculture, investigated the existence of technical efficiency change and assessed the effect of trade openness on the estimated technical efficiency. Using a Cobb-Douglas production function preferred to translog and fitted to data over 1980 to 2010 with maximum likelihood procedure, there was positive technical efficiency change. That is, technical inefficiency decreased over time. Landholding promoted technical efficiency. Contrary to findings of several studies, this paper showed that trade openness negatively impacted technical efficiency in agriculture in Ghana.
