The Macroeconomics of Imperfect Competition and Nonclearing Markets: A Dynamic General Equilibrium Approach
本书概述了Bénassy在将非瓦尔拉斯特征（如不完全竞争和名义刚性）融入动态宏观经济模型方面的贡献，这些模型基于理性预期和优化行为，旨在克服早期非均衡模型的缺陷。
Jean‐Pascal Bénassy is known as one of the pioneers of the so‐called ‘disequilibrium’ or ‘Neo‐Keynesian’ school of macroeconomics popular in the 1970s. This school’s approach was extremely useful in incorporating Keynesian inefficiencies and policy conclusions into macroeconomic models with rigorous microeconomic foundations, but has been the subject of criticism due to its lack of a foundation for price rigidity and price setting. These deficiencies made it impossible to integrate disequilibrium features into standard dynamic general equilibrium models such as those developed by Lucas, Kydland, Prescott, and others. Since the 1980s many economists, including Bénassy himself, have made substantial progress in overcoming the earlier weaknesses and in integrating disequilibrium elements into dynamic macroeconomic models that are fully based on rational expectations and optimising behaviour. This book provides an overview of several of Bénassy’s contributions to this field. The book’s central message is that non‐Walrasian features such as imperfect competition and nominal rigidities make dynamic macroeconomics a lot more interesting and can help to avoid many of the deficiencies of models that restrict themselves to Walrasian equilibrium states only.
