Empirical evidence suggests consumers rely on their shopping experiences to form beliefs about inflation. In other words, they "learn by shopping". I introduce this empirical observation as an informational friction in the New Keynesian model and use it to study its consequences for the...

This paper estimates a series of shocks to hit the US economy during the Great Depression, using a New Keynesian model with unemployment and bargaining frictions. Shocks to long-run inflation expectations appear to account for much of the cyclical behavior of employment, while an increase in...

Survey data on inflation expectations show that: (i) private sector forecasts and central bank forecasts are not fully aligned and (ii) private sector forecasters disagree about inflation expectations. To reconcile these two facts we introduce dispersed information in a New Keynesian model,...

Extending and modifying the canonical New Keynesian (NK) model, this study provides a novel approach to examine the impact of anticipated shocks called "news shocks" on business cycles. The analysis shows that news shocks are less stressful for an economy than commonly assumed. The main results...

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...

We introduce endogenous growth in an otherwise standard NK model with staggered prices and wages. Some results follow: (i) monetary volatility negatively affects long-run growth; (ii) the relation between nominal volatility and growth depends on the persistence of the nominal shocks and on the...

Consumer credit spreads significantly impact consumption and asset dynamics, affecting indebted households' spending behavior and the income sensitivity of consumption. Analyzing Danish data, we find that elevated credit spreads reduce consumption of indebted households. Our results suggest that...

Using federal funds futures data, we show the importance of surprise communication as a component of monetary policy for U.S. macro variables, both before and after 2008. While Gürkaynak et al. (2005) stress the importance of monetary policy communication for asset prices, much of the...
