“…In this study, we build a partial equilibrium model and examine how banks adjust their asset portfolio, particularly by using MBS, in response to changes in monetary policy. The literature identifies two motivations for banks to securitize loans: relaxation of capital constraints (also known as demand for liquidity, Altunbas, Gambacorta, & Marques, 2009;Berger & Udell, 1993;Carlstrom & Samolyk, 1995;Cerasi & Rochet, 2014;DeMarzo & Duffie, 1999) and transferring portfolio risks to third parties in the financial market (Dahiya, Puri, & Saunders, 2003;Dell'Ariccia, Igan, & Laeven, 2012;Marsh, 2006). These two motivations are considered as benefits of issuing MBS, which we model explicitly.…”
