Nonlinearity and Steady-State Changes in DSGE models

在第一个关于对名义利率具有零下限约束的动态随机一般均衡（DSGE）模型的项目中，我研究了在忽略零下限存在的DSGE模型中参数估计如何以及在多大程度上有偏差。在第二个采用DSGE随机趋势模型的项目中，我提出了一种方法来识别经济主体预期的新闻冲击，并量化这种冲击在解释宏观经济波动中的重要性。

In the first project regarding dynamic stochastic general equilibrium (DSGE) models with the zero lower bound constraint on the nominal interest rate, I examine how and to what extent parameter estimates can be biased in a DSGE model that ignores the existence of the zero lower bound. In the second project that employs DSGE models with stochastic trends, I propose a method to identify news shocks, which are anticipated by economic agents, and quantify the importance of such shocks in explaining macroeconomic fluctuations.
