作为宏观经济教学与实践的核心工具,IS-LM模型历时久远。虽然在模型产生之初,关于模型设定中,①缺乏微观基础、②假定价格黏性、③忽视预期影响、④将复杂经济体简单化为几个总量(I,C,G,NX)之间的关系,成了众口之矢,但不可否认的是,其作为指导师生及政策制定者深入理解宏观经济波动的权威框架,地位依旧不可撼动。 As a core tool for macroeconomic teaching and practice, the IS-LM model lasted far away. Although in the beginning of the model, in the model setting, ① lack of micro-foundation, ② assumed price stickiness, ③ ignore the expected impact, ④ simplify the complex economy into several aggregates (I, C, G, NX) However, it is undeniable that as a guide to instructing teachers, students and policy makers in deepening understanding of the authoritative framework of macroeconomic fluctuations, its position remains unshakable.
