We build a New Keynesian business-cycle model with rich household heterogeneity. A central feature is that matching frictions render labor-market risk countercyclical and endogenous to monetary policy. Our main result is that a majority of households prefer substantial stabilization of...

The strongest predictor of changes in the Fed Funds rate in the period 1982–2008 was the layoff rate. That fact is puzzling from the perspective of representative-agent models of the economy, which imply that the welfare gains of stabilizing employment fluctuations are small. This paper...

This paper analyses the monetary and fiscal policy implications of output gap estimates in times of crisis. The widening of output gaps observed in major OECD economies in the wake of the recent crisis has been mainly due to total factor productivity gaps, except in the United States where it...

We explore the effects of forward guidance at the zero lower bound when there is uncertainty over the lift-off date arising from: (i) the imperfect credibility of time-inconsistent forward-guidance promises; (ii) incomplete communication. We use a simple New Keynesian model to demonstrate that a...

We study whether the source of uncertainty shocks matters for optimal monetary policy, focusing on productivity and cost-push uncertainty shocks. Although both shocks deliver similar macroeconomic dynamics under an empirical Taylor rule, they generate very different dynamics under optimal...

We develop a simple model of defaultable debt and rational bubbles in the price of an asset, which can be pledged as collateral in a competitive credit pool. When the asset pledgeability is low, the down payment is high, and bubble investment is unleveraged, as in a standard rational bubble...

Households are subject to substantial tail risk in individual labor income, and the amount of income risk fluctuates over the business cycle. This paper proposes a New Keynesian production-based asset pricing model where idiosyncratic labor income risk is a key source of priced risk in equity...

This paper shows how uninsurable unemployment risk is crucial to qualitatively and quantitatively match macro responses to uncertainty shocks. Empirically, uncertainty shocks i) generate deflationary pressure; ii) have considerably negative consequences on economic activity; iii) produce a drop...

This article analyzes the effect of valuations-based capital requirements and concentration risk provisions on the risk-shifting response of the banking sector to monetary easing. It provides a closed economy DSGE model for the Euro zone with costly bank capital and two heterogeneous borrowers....
