Dynare forums

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: Select all

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);
    c=the/(1-the)*(1-alp)*exp(z)*k(-1)^alp*lab^(-alp)*(1-lab);
    k=exp(z)*k(-1)^alp*lab^(1-alp)-c+(1-del)*k(-1);
    z=rho*z(-1)+s*e;
end;

lab = 0.3;
z   = 0;
e   = 0;
end;
