I've just begun learning dynare, and i'dont exactly understand the difference between histval and initval in the case of deterministic modells.
For example, i'd like to simulate the basic acceletar-multiplicator modell of Samuelson, here is the code:
- Code: Select all
var y c i;
varexo g;
parameters c_a gamma psi;
c_a=1;
gamma=0.5;
psi=1;
model;
c=c_a+gamma*y(-1);
i=gamma*psi*(c-c(-1));
y=i+c+g;
end;
check;
histval;
y(0)=1;
c(0)=0.8;
end;
shocks;
var g;
periods 4:9;
values 5.1;
end;
simul(periods=100);
But it wont work, and i think it needs histval-s too. Please help!
Thanks!
