| 内容提要 | 在传统的Ramsey模型中，代表性个体的效用函数是时间可分的，这类效用函数由于其简洁性而广泛应用。但后续的研究发现，时间可分效用函数框架下得到的结论与现实经济差别很大。为此，经济学者通过拓展和完善Ramsey模型关于效用函数的设定，进而使得理论模型更好的拟合现实经济。20世纪80年代以来，经济学家在传统Ramsey模型的基础上通过引入习惯形成来解释现实经济问题，从而对很多宏观经济现象有了更加深刻的认识。本文首先介绍了习惯形成的含义以及习惯形成的基本分析框架，而后从消费储蓄理论、经济周期理论、经济增长理论、宏观经济政策以及资产定价理论几个维度考察了习惯形成对宏观经济学发展的影响。在此基础上，本文指出了习惯形成模型存在的不足以及未来发展方向。 |
| Abstract | The utility function in the Ramsey model is time separable, and it is widely used in macroeconomics for its simplicity. However, some empirical works find that the results derived in the Ramsey model could not be reconciled with the stylized fact of the economy. Therefore, Economists try to improve the Ramsey model by correcting the utility function. Habit formation is introduced in the Ramsey model in 1980s, and its introduction has deepened our understanding of the reality. This paper gives the definition of habit formation, and then we introduce the major framework of habit formation. The emphasis of this paper is to discuss the application of habit formation in the theory of consumption, saving, business cycle, economic growth, macro policy and asset pricing. Lastly, we point out the shortcomings of habit formation model and discuss its future development. |
