One of the great problems for these countries is that efforts to predict the consequences of agricultural policies are often confounded by the complex behavior patterns characteristic of households in semi-commercialized, rural economies. That is to say, most households in agricultural areas produce partly for sale and partly for their own consumption. They also purchase some of their inputs and provide some from their own resources. Any change in the policies governing agricultural activities will therefore affect not only production but also consumption and labor supply. These relations are what analysts attempt to capture in their efforts to model the behavior of agricultural households."
