International capital flows can create significant financial instability in emerging economies because of pecuniary externalities associated with exchange rate movements. Does this make it optimal to impose capital controls or should policymakers rely on domestic macroprudential regulation? This...

We investigate the role of macroprudential policies in mitigating liquidity traps driven by deleveraging, using a simple Keynesian model. When constrained agents engage in deleveraging, the interest rate needs to fall to induce unconstrained agents to pick up the decline in aggregate demand....

We challenge the widely held belief that New-Keynesian models cannot predict optimal positive inflation rates. In fact these are justified by the Phelps argument that monetary financing can alleviate the burden of distortionary taxation. We obtain this result because, in contrast with previous...

We build a business cycle model characterized by endogenous firm dynamics, where banks may prefer debt renegotiation, i.e. non-performing exposures, to outright borrowers' default. Debt renegotiations per se do not have adverse effects in the event of financial crisis episodes, but a large share...

Financial regulation is often framed as a question of economic efficiency. This paper, by contrast, puts the distributive implications of financial regulation center stage. We develop a model in which the financial sector benefits from risk-taking by earning greater expected returns. However,...

We build up and estimate a two-region DSGE model of the Euro area, investigating the interactions between the peripheral countries (PIIGS) and the rest of EMU. Our main focus is on the 2008-2009 financial crisis and on the subsequent 2010-sovereign bond crisis. One striking result is that the...

Can a DSGE model replicate the financial crisis effects without assuming unprecedented and implausibly large shocks? Starting from the assumption that the subprime crisis triggered the financial crisis, we introduce balance-sheet effects for housing market borrowers and for commercial banks in...

This paper investigates the response of the shadow economy to banking crises. Our empirical analysis, based on a large sample of countries, suggests that the informal sector is a powerful buffer, which expands at times of banking crises and absorbs a large proportion of the fall in official...

Following a seminal contribution by Bilbiie (2008), the Limited Asset Market Participation hypothesis has triggered a debate on DSGE models determinacy when the central bank implements a standard Taylor rule. We reconsider the issue here in the context of an exogenous money supply rule,...
