Eine Fehlinterpretation des Keynesianischen Modells


  • Felderer, Bernhard
  • Homburg, Stefan


In our paper we have shown that, avoiding logical inconsistencies, one cannot interpret the IS-curve as an equilibrium locus for the goods market. In the neoclassical synthesis the goods market is depicted by the AD/AS-diagram and, therefore, it cannot be represented by the IS-curve simultaneously. Concerning the pure IS/LM-model, only the point of intersection of the IS and LM curves defines an equilibrium in the goods market, not the IS-curve itself. Beyond that, this is an equilibrium only on the condition that prices are fixed. These inconsistencies are avoided by interpreting the IS-curve as an equilibrium locus for the capital market.
