I am using 4.0.4, and I have a simple Dynare model that behaves as follows. When I do stoch_simul(order=1), everything works fine and I see four sets of impulse response graphs. However, when I do stoch_simul(order=2), Dynare appears to solve the model successfully, but no impulse response graphs appear. Has anyone run into this? Is it (possibly) a bug in 4.0.4? I am new to Dynare, so I may well be missing something.
More details: when I run Dynare on Villaverde's rbc.mod (from the 'examples' section of the website), the impulse response graphs appear both for first order and second order. However, for my model, they appear at first order only. I believe Dynare has solved my model successfully to second order, because I see nonzero coefficients on cross-product terms in the policy and transition functions table. Dynare also displays theoretical moments, variance decomposition, matrix of correlations and coefficients of autocorrelation. Just no impulse response graphs at second order. I can provide my mod file if that would help.
Any help greatly appreciated.
Thanks,
Dave
