We study supply and demand shocks in a disaggregated model with multiple sectors, factors, input-output linkages, downward nominal wage rigidities, credit-constraints, zero lower bound. use the to understand how COVID-19 crisis, an omnibus shock, affects output, unemployment, inflation, leads coexistence of tight slack labor markets. show that negative sectoral are stagflationary, whereas defla...

We start from a natural extension of the classical model, assuming less than perfect risk perceptions. We propose first and second welfare theorems, by means of which we describe efficiencyenhancing policies. Notions of weak and strong adverse selection are promising for interpreti...

This paper estimates and compares four versions of the sticky price New Keynesian model for the Euro area, using a Bayesian approach as described in Rabanal and Rubio-Ramírez (2003). We find that the average duration of price contracts is between four and eight quarters, similar to the one estimated in the United States, while price indexation is found to be smaller. On the other hand, average ...
