Review of Agriculture, September 28, 1985 Interaction between Trading Capital and Productive Capital in Agriculture under Uncertainty Ajit K Chaudhury Kalyan K Sanyal The authors have recently developed a theoretical framework to analyse the interaction between productive and sterile activities in an underdeveloped, dualistic agrarian economy (EPW, Review of Political Economy, August 1984). In particular, they discussed the case where the sterile activity grows at the cost of the productive activity The discussion, however, was based on a deterministic model where the uncertainty associated with the prices of agricultural commodities was assumed away This paper tries to examine how the results obtained earlier are affected when uncertainty is explicitly introduced into the model.
