Steady state ratios in log-linearized equation

Hi Professor,

I would like to know in a log-linearized model such as Smets wouters, if we use calibrate the steady-state ratios using the averaged ratios based on the actual data. Should we use ratios based on log(data), or ratios of actual data?

The steady state ratios pretty much always refer to the actual data. The log only shows for the log-deviations from the steady state.
