The Clash of Economic Ideas interweaves the economic history of the last hundred years with the history of economic doctrines to understand how contrasting economic ideas have originated and developed over time to take their present forms. It traces the connections running from historical events to debates among economists, and from the ideas of academic writers to major experiments in economic policy. The treatment offers fresh perspectives on laissez faire, socialism and fascism; the Roaring Twenties, business cycle theories and the (...) Great Depression; Institutionalism and the New Deal; the Keynesian Revolution; and war, nationalization and central planning. After 1945, the work explores the postwar revival of invisible-hand ideas; economic development and growth, with special attention to contrasting policies and thought in Germany and India; the gold standard, the interwar gold-exchange standard, the postwar Bretton Woods system and the Great Inflation; public goods and public choice; free trade versus protectionism; and finally fiscal policy and public debt.

The standard allocative efficiency criteria used by economists (Pareto efficiency and Kaldor-Hicks efficiency) are fundamentally unable to rank a slave-labor system against a free-labor system. Given either set of initial property rights assignments the market can reach (or fail to reach) allocative efficiency (that is, allocate resources to their highest-valued uses), but welfare economics provides no meta-framework for ranking initial assignments. This finding underscores the limits to the usefulness of efficiency criteria: they cannot settle all questions, and unfortunately are least (...) decisive just where the stakes are greatest (namely, where wealth effects of alternative assignments are greatest). Explicitly ethical criteria are needed to make the ranking. Key Words: Pareto efficiency • Kaldor-Hicks efficiency • property rights • welfare economics. (shrink)

Israel Kirzner cautions us that, because commodity price arbitrage as such does not operate outside commodity markets, the logic of Pareto-improving entrepreneurship does not provide a “copybook example” for explaining the evolution of social institutions in general. He characterizes Menger’s theory of the emergence of money as non-entrepreneurial; by implication, while it assures us that some monetary standard will emerge, it does not assure us that a superior monetary standard will spontaneously emerge. I argue that entrepreneurial opportunities for private gain (...) do in fact drive the Mengerian evolution from barter to money, and systematically promote the emergence of superior monetary standards, though not necessarily the best conceivable standards. In choosing among potential exchange media to accept and offer, a pre-monetary trader has a private incentive to choose commodities that have whatever properties other traders prefer in their exchange media.Israel Kirzner nous met en garde sur le fait que parce que l’arbitrage des prix des marchandises en soi n’opère pas hors des marchés des produits, la logique de l’amélioration de l’esprit d’entreprise ne procure pas un “exemple classique” pour expliquer l’évolution des institutions sociales en général. Il caractérise la théorie mengerienne de l’émergence de la monnaie comme étant non entrepreneuriale; l’implication en est que si cette théorie nous assure qu’un certain étalon monétaire va émerger, elle ne peut affirmer avec certitude que cet étalon monétaire spontané sera supérieur.L’article suggère que des opportunités entrepreneuriales de gains privés orientent en effet l’évoluti- on décrite par Menger d’une situation de troc vers une économie monétaire et promeuvent systéma- tiquement l’émergence d’étalons monétaires supérieurs, bien que pas nécessairement les meilleurs étalons concevables. En choisissant parmi les intermédiaires d’échange potentiels lequel accepter ou offrir, un négociant d’avant l’ère monétaire a une insitation privée à choisir les marchandises dotées de propriétés que les autres négociants préfèrent dans le cadre de leurs échanges.
