I run the tutorial available in the dynare website (dynare.org/documentation-and … t/tutorial) and the standard deviation of the level version (example1) is different from the standar desviation of the log version (example2) but the steady state results are the same. I am working with a model similar to the small open economy of Schmitt-Grohe and Uribe, when I run the models in level or in log, the steady state and correlations results are the same but the standard deviation are different. I want to know if someone know the reason of this and which variance is more appropriate?

Thanks
