Empirical evidence demonstrates that credit standards, including lending margins and collateral requirements, move in a countercyclical direction. In this study, we construct a small open economy model with financial frictions to generate the countercyclical movement in credit standards. Our...

In the last two decades a body of literature highlights the role of financial frictions for explaining the development of key macroeconomic variables. Moreover, the financial crisis 2007-2009 again sheds light on the importance of this topic. In this paper, we contribute to the literature by...

We present an estimated dynamic stochastic general equilibrium model of stock market bubbles and business cycles using Bayesian methods. Bubbles emerge through a positive feedback loop mechanism supported by self-fulfilling beliefs. We identify a sentiment shock that drives the movements of...

This paper studies the cyclical properties of real GDP, house prices, credit, and nominal liquid financial assets in 17 EU countries, by applying several methods to extract cycles. The estimates confirm earlier findings of large medium-term cycles in credit volumes and house prices. GDP appears...

This paper studies the impact of imperfect banking competition on aggregate fluctuations using a DSGE framework that features a Cournot banking sector. The paper highlights a new propagation mechanism of imperfect banking competition that operates via the dynamics of the expected marginal...

We examine, conditional on structural shocks, the macroeconomic performance of different countercyclical capital buffer (CCyB) rules in small open economy estimated medium scale DSGE. We find that rules based on the credit gap create a trade-off between the stabilization of fluctuations...

This paper investigates in a non-linear setting the impact on the real economy of frictions stemming from the financial sector. We develop a medium scale DSGE model with a banking sector where an occasionally binding constraint on banks' capital induces a relevant non-linearity. The model -...

Asymmetric information is crucial for understanding the disruption of the supply of credit. This paper studies a dynamic economy featuring asymmetric information and resulting adverse selection in credit markets. Entrepreneurs seek loans from banks for projects, but asymmetric information about...

Credit constraints that link a private agent's debt to market-determined prices create a systemic credit externality that drives a wedge between competitive and (constrained) socially optimal equilibria, which induces private agents to "overborrow". We quantify the effects of this externality in...

This paper studies how non-rational risk shocks affect the macroeconomy. Exploiting survey data on expectations of financial executives, belief distortions on financial markets identify a non-rational risk shock. Surprises in beliefs in credit spreads measure belief distortions, and are used as...
