I am working on a DSGE model with baseline as the Gali 2015 (by Johannes) with additions of CBDC and deposit fee.

As for the parameters and calibration of the parameters, I have questions:

Can I use the same parameters as used in the Gali 2015 mod 3? Because;:

I am going to test for Financial crisis. What happened (by running simulation with the baseline model without our adjustments) and then run simulation with our adjusted model and compare how fast we would come out of a recession in our economy.

If not, how can I calibrate them in dynare?

Also, for the parameters we have added, how can we do calibration on them? They are not so far applied in any models we have seen:

: eta_cbdc = 1.5; % Semi-elasticity of CBDC demand
eta_paper = 0.5; % Semi-elasticity of paper currency demand
alpha_cbdc = 0.7; % Weight of CBDC in total money demand
gamma = 0.05; % Sensitivity of deposit fee
gamma_zero = 0; % No deposit fee when interest rate high

Nobody can make that decision for you. The Gali model is very stylized and not targeted towards a particular country or time period. It’s more about stylized facts. Given the round numbers you picked for the additional parameters, that may be all you need.

No that is true. I have never calibrated parameters until this model. Therefore I wanted to know if there are certain ways to estimate them if not found in other research papers. I want to identify a number that makes sense.
So I wished to learn more about ways to calibrate the parameters or maybe there is some topic about this, but from my search i could not find more than a few comments about it.
If there are any pages here I can check to understand and learn more, especially since these parameters are not used before not in the most places at least.,
