In this paper we investigate the effects of uncertainty shocks on economic activity in the euro area by using a Dynamic Stochastic General Equilibrium (DSGE) model with heterogenous agents and a stylized banking sector. We show that frictions in credit supply amplify the effects of uncertainty...

We introduce frictional financial intermediation into a HANK model. Households are subject to idiosyncratic and aggregate risk and smooth consumption through savings and consumer loans intermediated by banks. The banking friction introduces an endogenous countercyclical spread between the...

How should monetary policy respond to changes in financial conditions? In this paper we consider a simple model where firms are subject to idiosyncratic shocks which may force them to default on their debt. Firms' assets and liabilities are denominated in nominal terms and predetermined when...

I add a moral hazard problem between banks and depositors as in Gertler and Karadi (2009) to a DSGE model with a costly state verification problem between entrepreneurs and banks as in Bernanke et al. (1999) (BGG). This modification amplifies the response of the external finance premium and the...

This paper provides empirical evidence on the role played by loan supply shocks over the business cycle in the Euro Area, the United Kingdom and the United States from 1980 to 2010 by applying a time-varying parameters VAR model with stochastic volatility and identifying these shocks with sign...

How do prices react to large aggregate shocks? Our new micro-data evidence on value-added tax changes shows that prices react (i) flexibly and (ii) asymmetrically to large positive and negative shocks. We use it to quantitatively evaluate the performance of prominent pricing models. We show that...

This paper evaluates whether macroeconomic uncertainty changes the impact of oil shocks on the oil price. Using a structural threshold VAR model, we endogenously identify different regimes of uncertainty in which we estimate the effects of oil demand and supply shocks. The results show that...

We study what makes government bonds a safe asset. Building on a sample of monthly changes in government bond yields in 40 advanced and emerging countries, we analyse the sensitivity of yields to country specific fundamentals interacted with changes in global risk (VIX). We find that inertia...
