Hi Johannes, Le vendredi 01 mars 2013 à 16:14 -0500, Johannes Pfeifer a écrit :

the attached mod-file runs with the code:

//periods 4, 5, 6, 7, 8;

periods 4:8;

When I switch from the second to the first line, which should be equivalent, I get

ERROR: rbc_det3.mod:68.1-71.12: shocks/conditional_forecast_paths: variable EfficiencyInnovation: number of periods is different from number of shock values

This is not a bug but a desired behavior. The two different ways in which you wrote the `periods' statement have a different semantics. When you write a range, you mean that you want the same value for the shocks in all periods from 4 to 8, and therefore you should put only one value in the `values' statement. I understand that it is a bit counter-intuitive when you provide a vector in the `values' statement. But this is how things have always been in Dynare.
