On the one hand, recently a number of theoretical models have highlighted the role of credit market frictions in propagating and amplifying macroeconomic shocks. On the other hand, it still seems an open question whether this role is quantitatively significant. Our paper tries to fill this gap....

We describe how to adapt a first-order perturbation approach and apply it in a piecewise fashion to handle occasionally binding constraints in dynamic models. Our examples include a real business cycle model with a constraint on the level of investment and a New Keynesian model subject to the...

Occasionally binding credit constraints (OBC) have recently been explored as a promising way of modeling financial frictions. However, given their highly non-linear nature, most of the literature has concentrated on small models that can be solved using global methods. In this paper, we...

This paper proposes a macroeconomic model with financial intermediaries (banks), in which banks face occasionally binding leverage constraints and may endogenously affect the strength of their balance sheets by issuing new equity. The model can account for occasional financial crises as a result...
