We identify an inflationary technology news shock as the leading source of business cycle variations for the postwar U.S. economy. This shock acts like a demand shock: it induces strong positive comovement in real quantities - GDP, consumption, investment - and weak positive comovement between...

We study the transmission of monetary policy shocks in a model in which realistic heterogeneity in price rigidity interacts with heterogeneity in sectoral size and input-output linkages, and derive conditions under which these heterogeneities generate large real effects. Empirically,...

I develop a New Keynesian model with preferences over safe assets (POSA) calibrated using evidence on the wedge between household discount rates and market interest rates. POSA attenuate intertemporal consumption smoothing and thus the household's responsiveness to future interest rates, the...

Central bank announcements move financial markets. The response of inflation and growth expectations, on the other hand, is often small or even counterintuitive. Based on tick-by-tick futures prices on bonds and stock prices, I confirm these seemingly puzzling results for the euro area and...

Why is an inverted yield-curve slope such a powerful predictor of future recessions? We show that a decomposition of the yield curve slope into its expectations and risk premia components helps disentangle the channels that connect fluctuations in Treasury rates and the future state of the...

New Keynesian theory identifies a set of principles central to the design and implementation of monetary policy. These principles rely on the ability of a central bank to manage expectations precisely, with policy prescriptions typically derived under the assumption of perfect information and...

In this paper we analyze a hybrid small-scale New-Keynesian model with an arbitrary frequency of the agents’ synchronized decision making. We study the impact of various demand and supply shocks on the dynamics of the model variables. We show that the corresponding impulse-response functions...

We show that actively stabilizing economic activity plays a more prominent role in the conduct of monetary policy when potential output is subject to hysteresis. We augment a basic NewKeynesian model by hysteresis in potential output and contrast simulation outcomes of this extended model to the...

In this paper we investigate the effects of uncertainty shocks on economic activity 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 shocks on economic...
