Perspectives on the Pulp and Paper Industry

Obwona (2000) estimated a trans log production function to determine technical efficiency differentials between small- and medium-scale tobacco farmers in Uganda using a stochastic frontier approach. The estimated efficiencies were explained by socioeconomic and demographic factors. The results showed that, credit accessibility extension services and farm assets contribute positively towards the improvement of efficiency. One major drawback of this study is the inability of the author to show in clear terms whether there is any differential in efficiency between the two groups of farmers. Most of the earlier studies cited concentrated on aggregate data and employed relatively simple statistical tools. More importantly, there were no efforts made to quantify...
