I am having a problem with the steady state as follows, can anyone help me?
var x infl i;
varexo uis uas ui;
parameters alf bet lam rho pi1 pi2;
bet=0.99;
rho=-ln(bet);
model;
x = x(+1)-alf*(i-infl(+1)-rho)+uis;
infl = bet*infl(+1)+lam*x+uas;
i = rho +(1-rho)*(pi1*infl+pi2*x)+ui;
end;
varobs x infl i;
initval;
x=0;
infl=0;
i=rho;
end;
steady;
check;
estimated_params;
alf, normal_pdf, 1, 0.5;
lam, beta_pdf, 0.5, 0.18, 0,1;
pi1, gamma_pdf, 1.5, 0.25;
pi2, gamma_pdf, 0.5, 0.1;
stderr uis, inv_gamma_pdf, 2, inf;
stderr uas, inv_gamma_pdf, 2, inf;
stderr ui, inv_gamma_pdf, 2, inf;
end;
estimation (datafile=Vietnam,mh_replic=100000,prefilter=1, conf_sig=0.90) x infl i;
The error as follows:
Warning: Some of the parameters have no value (alf, lam, pi1, pi2) when using steady. If these parameters are not
initialized in a steadystate file, Dynare may not be able to solve the model...
