In Bangladesh, where resources are scarce and opportunities for new technologies are lacking, efficiency studies will be able to show that it is possible to raise productivity by improving efficiency without new investment or developing new technology. It is generally assumed that in Bangladesh farmers are inefficient at producing wheat and there are significant efficiency differences among regions, among farm groups and also among crops. After the measurement of efficiency differences, proper measures can be undertaken to reduce them. It is equally important to identify farm specific factors, which influence inefficiency effects or efficiency. However, the accuracy of the identification of the impact of different factors on the inefficiency effects or efficiencies depends on factors including the functional form of the production technology, the nature of the random error component the distribution of the inefficiency component and the nature of the production function. After the measurement of efficiencies on various dimensions, different components of agricultural policy can be adopted.

This study reveals that production of wheat in Bangladesh is profitable and small farmers earned significantly higher yield and net returns per hectare than other farm groups. Technical efficiency scores estimated from different Cobb-Douglass and Translog models vary from 46 percent to 99 percent and 70 to 99 percent respectively and the maximum efficiency attained at the levels 90-100 percent. Average gross technical efficiency estimated from Cobb-Douglas frontiers varies from 86 to 89 percent whereas average net technical efficiency varies from 90 to 92 percent. This study also reveals that wheat output can be increased in the range 8-11 percent by using the existing resources and technology. Average gross technical efficiency estimated from Translog models is 93 percent whereas average net technical efficiency is 94 percent, which reveals that wheat output can be increased in the range 6-7 percent by using the existing resources and technology. It is obvious that environmental factors have positive impact on both production and technical efficiency. The development of advanced technology is the only option to increase wheat production in the long-run.
