This paper assesses the role of financial variables in real economic fluctuations, in view of analysing the link between financial cycles and business cycles at the global level. A Global VAR modelling approach, which has been proved suitable for modelling country or regional linkages, is used...

After the recent banking crisis in 2008, financial market conditions have turned out to be a relevant factor for economic fluctuations. This paper provides a quantitative assessment of the impact of financial frictions on the U.S. business cycle. The analysis compares the original Smets and...

This paper analyzes the boom–bust cycle driven by rational bubbles in an overlapping generations economy that is subject to borrowing constraints. At the heart of the analysis is the interplay among savings, investment, and the interest rate. Bubbles are more likely to crowd investment in, the...

This paper builds models of nonlinear dynamics in the aggregate investment and borrower net worth to study the causes and nature of endogenous credit cycles. The basic model has two types of projects: the Good and the Bad. The Good projects rely on the inputs supplied by others who could...

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...

In this paper, we aim to compare the anatomy of the impact of the COVID-19 outbreak and the Great Financial Crisis (GFC) in the context of an emerging market economy. To this end, we develop a small open economy DSGE model with the Bernanke-Gertler-Gilchrist financial accelerator that features...

This paper develops a Dynamic Stochastic General Equilibrium (DSGE) model to study how the instability of the banking sector can amplify and propagate business cycles. The model builds on Bernanke, Gertler and Gilchrist (BGG) (1999), who consider credit demand friction due to agency cost, but it...
