Abstract

This paper uses cost function analysis to examine the nature of technological change in sorghum production between improved technology and traditional technology. We also estimate the returns to scale in sorghum production in Eastern Uganda. Results indicate that the production function has not yet undergone structural change between traditional and improved technologies contrary to the results of the cost function. The production function exhibited constant returns to scale contrary to increasing returns to scale exhibited by the cost function results for the two technologies. The implication is that the dual approach is not appropriate for sorghum production in Eastern Uganda.
