I work with a DSGE model in which I have to see the reaction of the inflation targeting to differet shock but the problem that I donâ€™t have a special fonction of inflation targeting to write in matlab code but to have an idea about the write code of an RBC model or a DSGE model (see the example of user guide dynare) this is the right code of the example in the user guide:

var y c k i l y_l w r z ;

varexo e;

parameters beta psi delta alpha rho epsilon;

alpha = 0.33;

beta = 0.99;

delta = 0.023;

psi = 1.75;

rho = 0.95;

epsilon = 10;

model;

(1/c)= beta*(1/c(+1))*(1+r(+1)-delta);*

psic/(1-l) = w;

c+i = y;

y = (k(-1)^alpha)*(exp(z)**l)^(1-alpha);*

w = y((epsilon-1)/epsilon)(1-alpha)/l;

r = y*((epsilon-1)/epsilon)*alpha/k(-1);

i = k-(1-delta)*k(-1);*

y_l= y/l;

z = rhoz(-1)+e;

end;

initval;

k = 9;

c = 0.76;

l = 0.3;

w = 2.07;

r = 0.03;

z = 0;

e = 0;

end;

steady;

varobs y;
