楼主,你好!!线性化DSGE模型在校准后要求求解出稳定的解,并将该解的状态空间形式用于估计。请问:求出 ...
I shall reply u in english, the computer i am using has no chinese input. i'll answer u the
first question later on. But the second can be explained here.
There are more than two methods of solving linear rational expectation model, most of them are developed based on understand of linear dynamic system, such as differential equation system. The industrial standard of solving LRE is Blanchard Kahn method, and there are other prominent methods: Binder-Pesaran method, Uhlig's, Klein's, Sims', etc. The Dynare use Anderson-Moore algorithm to solve LRE, which is based on Klein's. And this method do not need to differentiate endogenous variables and jump variables, that's why you do not need to specify jump variables in Dynare. I did not study Juillard's and Uribe's. Thus I can't tell you the difference yet. But I think they won't be very different from each other.
