Hello Professor，
Last time I posted this post, I didn’t express myself clearly enough. I will send it again to seek your help.
The ① line in this figure serves as the benchmark analysis, indicating a positive standard deviation of the expected impact on housing prices throughout the entire process; The ② and ③ lines represent the author’s implementation of a positive standard deviation housing price expectation shock in the 1:5 period, and then a counterfactual analysis is conducted by changing the magnitude of the shock in the sixth period, using weak positive housing price expectation and a negative standard deviation housing price expectation to change the magnitude of the shock in sequence.
May I ask how to write the code for changing the size of the same impact in the sixth issue? The impact code for line ③ in my code is shown below, but it was prompted by dynare that the housing price expectation was raised twice and cannot be run. May I ask where the mistake is? How to write code that impacts this part?
