提出了一个基于垄断竞争的一般均衡宏观经济模型。该模型在短期内表现出传统的乘数，但由于自由进入，乘数在长期内消失。所有的代理人都是完全理性的。凯恩斯主义的结果是垄断竞争假设的结果，这造成了最优私人行为和最优社会行为之间的分歧。
A general equilibrium macroeconomic model based on monopolistic competition is presented. The model exhibits a traditional multiplier in the short run, but due to free entry, the multiplier disappears in the long run. By construction all agents are fully rational. The Keynesian results are a consequence of the assumption of monopolistic competition, which creates a divergence between optimal private behavior and optimal social behavior.
