【摘要】 在对理性预期宏观经济学的前提条件与基本假设细致分析的基础上,对其中的市场持续出清的假设提出了不同的看法。它是基于劳动力市场上随处可见的长期契约存在的事实之上的,即由于议定工资的长期合同存在,工资的变动呈现出一定的粘性。运用这个观点证前了即使预期的形成是理性的,政府旨在影响实际产出与就业率的货币政策也将是有效的。这不同于理性预期学派的“政策无效论”的观点。更多还原

【Abstract】 Based on a detail analysis on the basic assumption of macroeconomics on rational expectations,the paper proposes a different view about the assumption of continuous of market clear in the light of common existing faots of long-run contract in labour market,which reveal a certain stickiness of the wage variation.

It differs from "the theory of policy invalidation" from the school of rational expectations.更多还原
