Anybody can help? I did not understand why dynare tell me there are one mixed variable in the model after running the model file since oo_.dr.nboth=1?

It seems that there are no mixed variables in the model.

mixed variables are those that appear at current, past and future period in the model (i.e. at t, t+1 and t-1). The number of such variables is stored in oo_.dr.nboth.

[code]var c k lab z;

varexo e;

parameters bet the del alp tau rho s;

bet = 0.987;

the = 0.357;

del = 0.012;

alp = 0.4;

tau = 2;

rho = 0.95;

s = 0.007;

model;

(c^the*(1-lab)^(1-the))^(1-tau)/c=bet*((c(+1)^the*(1-lab(+1))^(1-the))^(1-tau)/c(+1))*(1+alp*exp(z(+1))*k^(alp-1) lab(+1)^(1-alp)-del);*e;

c=the/(1-the)(1-alp)exp(z)k(-1)^alplab^(-alp)(1-lab);

k=exp(z)k(-1)^alplab^(1-alp)-c+(1-del)k(-1);

z=rhoz(-1)+s

end;

initval;

k = 1;

c = 1;

lab = 0.3;

z = 0;

e = 0;

end;

shocks;

var e;

stderr 1;

end;

steady;
