R. Hicks quien explicó que el origen del dispositivo SI/LL es una adaptación de su análisis de intercambio de mercados a la Teoría general de J. M. Keynes. Si bien parcialmente esto es verdad, el modelo SI/LL atañe otra textura muy distinta de la que reconocemos porque su origen está relacionado a ideas desarrolladas por R. F. Harrod y J. E Meade, quienes llevaban más tiempo intentando extraer el modelo algebraico de Keynes. De manera parecida a la aportación de J. E. Meade, la introducción de las expectativas estáticas en la eficiencia marginal del capital de la estructura lógica del modelo SI/LL de Hicks, nos conduce al resultado de Keynes, a saber, una economía de precios flexibles no siempre converge a un equilibrio con pleno empleo.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract In this article we study the logical structure of J. R. Hicks' SI/LL model. He explained that the origin of the SI/LL device lies in an adaptation of the analysis of the exchange of markets to the General Theory of J. M. Keynes. Although this is partially true, the SI/LL model concerns a texture that is very different from the one we are familiar with, since its origin is related to ideas that were deve­loped by R. F. Harrod and J. E. Meade, who took more time trying to extract the algebraic model of Keynes. Similar to the contribution of J. E. Meade, Hicks' SI/LL model's introduction of the static expectations in the marginal efficiency of the capital of the logical structure, leads us to Keynes' result: an economy of flexible prices doesn't always converge with an equilibrium with full employment.]]></p></abstract>
