- Ok, yes. I see. It is indeed that case that if the growth adjusted real interest rate R/(pi*g) is smaller than 1, then you can only have a steady state if beta is bigger than 1. But then again, there is the question of beta being growth adjusted.
- But the growth adjustment is only relevant if you are not having log utility. With log utility, there is no adjustment for beta. Regarding a reference, Romer’s textbook covers this in continuous time in section 2.2. I have just sent you my own lecture slides where this relationship is derived.
