Abstract
This paper quantifies the rates of return of different agricultural inputs, and studies whether labour and fertilizers are substitutes or complements. The study uses detailed farm level data based on the survey conducted by the International Food Policy Research Institute and Bangladesh Institute of Development Studies, covering sixteen villages in 1981-82. Different definitions of substitutes and complements are used. We find that the use of a price definition for classifying inputs and substitutes and complements is not possible when some of the inputs are not purchased in a market place. On the basis of a quantity definition, (Fisher's), fertilizer and labour are complements.
