Hope you are keeping well. I run a DSGE model with real money reserve (m) and all run well. But I find the steady state value of m negative !! What is this means? I hope you can help me, always thank you, professor. book1EmM2.mod (1.3 KB)

That indeed does not make sense. A money stock cannot be negative. Your equation for m contains the term /(1-(1/1+r)), which is negative. Are you sure it is correct?
