Higher wages lead to the use of larger sprayers which may be animal- or tractor-drawn. Assessment. The selective use of new power sources (particularly tractors) for power-intensive operations has often been viewed as a sign of inefficiency. Since a farmer makes a huge investment in a tractor, why not use it for all operations? U.S. studies carried out in the 1920s and 1930s show clearly that there is nothing inefficient in the selective use of tractors for power-intensive operations.Mechanical rice milling has been controversial in Indonesia (Timmer 1974, Collier 1974) and is now penetrating Bangladesh. It reduces the demand for women workers, who-because of social customs-have few employment options. On efficiency grounds, milling machines are clearly warranted; on equity grounds, their effects may be harmful.
