Dynare forums

Hello,
I am trying to replicate "Adolfson,M. ,S. Laseen, J. Linde, and M. Villani 2007(Bayesian Estimation of an open Economy DSGE model)" with Thailand data and I adopt the baseline code from MMB (http://www.macromodelbase.com/home)

Since I am new Dynare user, I got stuck and I have no idea how wrong it is. Please,help me for some suggestions.


Thank for your suggestions

The code

I found this problem but I don't know what it means.

You cannot estimate the model with that mod-file. You are neglecting parameter dependence. After running estimation, Dynare will update the estimated parameters but not take any dependence into account that you did not specify. Rather, your calibration only once updates the other parameters depending on the estimated one. That’s why you should use model-local variables (the ones with the pound operator). See Remark 4 (Parameter dependence and the use of model-local variables) in Pfeifer(2013): "A Guide to Specifying Observation Equations for the Estimation of DSGE Models" https://sites.google.com/site/pfeiferecon/Pfeifer_2013_Observation_Equations.pdf.
This will solve your problem.

Dear Prof. Dr. Johannes Pfeifer

Thank so much for your suggestions. I am trying to follow your suggestions.

Dear Prof. Dr. Johannes Pfeifer

It is me again. I tried to adopt your advice ,but it is still not work. I am not sure whether my code correct or not.
I found these problems. I have no idea how to solve.

Could please correct my code?

You still have parameter dependences:

Code: Select all

%Steady state para
b_w=(lambda_w*sigma_L-(1-lambda_w))/((1-beta*xi_w)*(1-xi_w));
eta_0=b_w*xi_w;
eta_1=sigma_L*lambda_w-b_w*(1+beta*xi_w^2);
eta_2=b_w*beta*xi_w;
eta_3=-b_w*xi_w;
eta_4=b_w*beta*xi_w;
eta_5=b_w*xi_w*kappa_w;
eta_6=-b_w*beta*xi_w*kappa_w;
eta_7=1-lambda_w;
eta_8=-(1-lambda_w)*sigma_L;
eta_9=-(1-lambda_w)*tau_y/(1-tau_y);
eta_10=-(1-lambda_w)*tau_w/(1+tau_w);
eta_11=-(1-lambda_w);

pi=mu/mu_z; %A.3
R=(pi*mu_z-tau_k*beta)/((1-tau_k)*beta);%A.2
R_f=nu*R+1-nu; %A.17
eta_mc=lambda_mc/(lambda_mc-1); %Substitution elasticity among imported consumption goods
eta_mi=lambda_mi/(lambda_mi-1);%Substitution elasticity among imported investment goods

gamma_id=((1-omega_i)+omega_i*(eta_mi/(eta_mi-1))^(1-eta_i))^(1/(1-eta_i)); %A.11
gamma_cd=((1-omega_c)+omega_c*(eta_mc/(eta_mc-1))^(1-eta_c))^(1/(1-eta_c)); %A.9
gamma_dc=1/gamma_cd;
gamma_cmc=((1-omega_c)*((eta_mc-1)/eta_mc)^(1-eta_c)+omega_c)^(1/(1-eta_c)); %A.10
gamma_mcc=1/gamma_cmc;
gamma_imi=((1-omega_i)*((eta_mi-1)/eta_mi)^(1-eta_i)+omega_i)^(1/(1-eta_i)); %A.12
gamma_mii=1/gamma_imi;


Here, b_w depends on xi_w, which has not been defined yet.
