The first to apply the theory of imperfect competition to the buying side represented by agricultural processing industries vis-à-vis farmers. On the occasion, he devised several novel diagrammatical tools for duopoly and bilateral monopoly. Concentrating on cigarettes and meat-packing industries, he subjected the production and industrial organisation of agricultural industries to a detailed analysis.
In a first departure from the conventional production function, he included the working day among the ordinary variables of that function. As a member of the dissenting ‘Ames Group’, he wrote a prizewinning critical analysis of the United States farm policy and formulated economically efficient policy alternatives. At Vanderbilt he founded a school of thought characterised by an abiding interest in the economic development of the South with special reference to agriculture.
In the latter part of his career he shifted the focus of his research to agriculture in the world, with particular attention to agricultural development in lowincome countries. His model involving the ‘agricultural surplus’ has become a frequent tool of research. Instructor, Assistant Professor, Association Professor, Iowa State College, 1938-1944.
