by Ugo Albertazzi and Lucia Esposito September 2017

The model developed in this paper extends the framework of self-fulfilling credit market freezes proposed by Bebchuk and Goldstein (2011) by endogenizing firms' investments decisions.

Because of the resulting strategic complementarities between firms and banks, low credit demand expectations reduce credit supply and viceversa. This two-way feedback loop explains why a severe slump in aggregate demand may be associated with a disruption in lending caused by a financial crisis. Replies to the euro area Bank Lending Survey by individual Italian banks provide support to the model's conclusions.
