Researchers from Europe, North America, Taiwan, and Brazil present six papers from a symposium on the historical epistemology of economics, along with an essay on the “value paradox” in art economics and a classic essay on Augustin Cournot and the bargaining problem. Symposium essays discuss the scientific understanding of the 18th-century French physiocrats, Stanley Jevons’ and Alfred Marshall’s diagrammatical methods, how US military administrators of postwar Germany reconfigured the institutional context to generate policy-relevant economic statistics and reports, Gérard Debreu’s personal values and their influences on his theorizing about economic value, and the French tradition of historical epistemology.
