This course surveys the development of economic analysis from the mid-nineteenthcentury up to 1960. The early part of this period was marked by a shift fromthe classical-Marxian focus on objective, or materialist, explanations of valueand distribution to the neoclassical emphasis on subjective factors. The theoretica ltraditions associated with Marshall, Walras and the Austrians will be comparedwith a view to understanding how these distinct traditions emerged, contended with one another, and shaped the discipline. Due attention will be paid to institutionalist economics, to the socialist calculation debates, and to the impact of the economists who emigrated from Europe during the political crises of the 1930s.The course concludes with an assessment of the challenge to mainstreameconomics posed by postwar writings of the circle of economists centered at theUniversity of Cambridge, including Joan Robinson and Piero Sraffa.
