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...

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,...

A popular argument in favour of price stability is that the inflation-tax burden would disproportionately fall on the poor because wealth is unevenly distributed and portfolio composition of poorer households is skewed towards a larger share of money holdings. We reconsider the issue in a DSGE...

In the workhorse DSGE model, the optimal steady state in flation rate is near to zero or slightly negative and infl ation is almost completely stabilized along the business cycle (Schmitt-Grohè and Uribe, 2011). We reconsider the issue, allowing for agent heterogeneity in the access to the...
