指出当前教科书中的AS/AD模型存在逻辑不一致性,其组成部分源于不同且矛盾的模型,且伴随的非均衡调整故事与现实不符。作者提出替代模型,其中凯恩斯调整通过沿制度决定的价格水平向量移动AS/AD曲线实现。

Abstract

This paper explains that the AS/AD model as currently presented in the tests is seriously flawed. It does not fulfill the minimum requirement of a model: logical consistency. Its component parts are derived from models that reflect different, and inconsistent, models of the economy. Moreover, the appropriate disequilibrium adjustment story that appropriately accompanies it is inconsistent with observed reality. In this alternative model, Keynesian adjustment occurs through shifting AS/AD curves along institutionally determined price level vectors rather than through movements along the AS/AD curves.
