Some but not all of the rapid dynamic response in these cases can be explained by the coercion of colonialists, or by the development of infra- structure facilities by the colonial power or by a crop's promotion by "chartered companies" and cartel-type agency houses. More recently, the idea of an economically inert peasantry has been subjected to serious challenge. First, there are those economists led by Professor Jones [1960] and Professor T. W. Schultz [1964], who find ample evidence that subsistence farmers are economic men who do maximize in the utilization of their available economic resources given the available technology. Such farmers may be operating at low absolute levels of production but none-the- less they are optimizing at the ceiling of the available technological possibilities. This group argues that what is fundamentally lacking is improved technology. The obvious solution under such circumstances is to give first priority to the development of new technology to alter the production possibilities available to the subsistence farmer. Sizeable investment in new technology, if successful, would enable the subsistence farmer to apply his economizing skills at a higher absolute level of production. Second, a large number of economists have been conducting rigorous empirical research to determine whether or not such farmers respond to economic incentives.
