In this paper we compare two standard extensions to the New Keynesian model featuring financial frictions. The first model, originating from Kiyotaki and Moore (1997), is based on collateral constraints. The second, developed by Carlstrom and Fuerst (1997) and Bernanke et al. (1999), accentuates...
