The Sonnenschein–Mantel–Debreu theorem is an important result in general equilibrium economics, proved by Gérard Debreu, , and Hugo F. Sonnenschein in the 1970s. It states that the excess demand curve for an exchange economy populated with utility-maximizing rational agents can take the shape of any function that is continuous, has homogeneity degree zero, and is in accordance with Walras's law. This implies that the excess demand function does not take a well-behaved form even if each agent has a well-behaved utility function. Market processes will not necessarily reach a unique and stable equilibrium point.

  • Als Sonnenschein-Mantel-Debreu-Theorem bezeichnet man in der Mikroökonomik und dort speziell in der Theorie des allgemeinen Gleichgewichts einen auf Hugo F. Sonnenschein, und Gérard Debreu zurückgehenden Satz. Er besagt vereinfacht, dass die aggregierten Überschussnachfragefunktionen, die zu einem mit gängigen Annahmen konstruierten Modell des allgemeinen Gleichgewichts gehören, nur über einige bestimmte, allgemeine Eigenschaften verfügen, ansonsten aber keine konkreten Aussagen über ihre Gestalt möglich sind.

  • El teorema económico formulado en primer lugar por Hugo F. Sonnenschein en 1972 y 1973​​ (y complementado en 1974 por Rolf Mantel​ y Gérard Debreu​) evidencia que las funciones de demanda y oferta resultantes del modelo de equilibrio general de Arrow-Debreu pueden asumir cualquier forma, lo cual refuta las conclusiones de unicidad y estabilidad del equilibrio general. Este teorema, es por tanto un resultado fundamental para la teoría general de equilibrio económico.​ (es)
  • Le théorème de Sonnenschein, établi entre 1972 et 1974 dans une série d'articles par Hugo F. Sonnenschein, et Gérard Debreu, d'où le fait qu'on l'appelle aussi théorème de Sonnenschein-Mantel-Debreu, montre que les fonctions de demande nette du modèle de Kenneth Arrow et Gérard Debreu de l'équilibre général peuvent avoir une forme quelconque, ce qui empêche de tirer de ce modèle des résultats (unicité, stabilité, "lois" de statique comparative) autres que l'existence d'au moins un équilibre général.

This implies that the excess demand function does not take a well-behaved form even if each agent has a well-behaved utility function. Market processes will not necessarily reach a unique and stable equilibrium point. More recently, Jordi Andreu, Pierre-André Chiappori, and Ivar Ekeland extended this result to market demand curves, both for individual commodities and for the aggregate demand of an economy as a whole. This means that demand curves may take on highly irregular shapes, even if all individual agents in the market are perfectly rational. In contrast with usual assumptions, the quantity demanded of a commodity may not decrease when the price increases. Frank Hahn regarded the theorem as a dangerous critique of mainstream neoclassical economics. (en)
  • O teorema de Sonnenschein–Mantel–Debreu (nomeado após Gérard Debreu, [es], e Hugo F. Sonnenschein) é um resultado em economia de equilíbrio geral. Ele afirma que a função excesso de demanda para uma economia não é restringida pelas usuais restrições de racionalidade sobre demandas individuais na economia. Assim, premissas de racionalidade microeconômicas não tem implicações macroeconômicas equivalentes. As principais implicações do teorema são que, com muitos mercados interdependentes dentro da economia, pode não existir um único ponto de equilíbrio. considerou o teorema como a crítica mais perigosa contra economia ortodoxa micro-fundamentada.
