The Natural Rate of Interest Through a Hall of Mirrors
Prevailing explanations of persistently low interest rates appeal to a secular decline in the natural interest rate, or r-star, due to factors outside monetary policy's control. We propose informational feedback via learning as an alternative explanation for persistently low rates, where monetary policy plays a crucial role. We extend the canonical New Keynesian model to an incomplete information setting where the central bank and the private sector learn about r-star and infer each other's information from observed macroeconomic outcomes. An informational feedback loop emerges when each side ...

Attention and Fluctuations in Macroeconomic Uncertainty
This paper studies a dispersed information economy in which agents can exert costly attention to learn about an unknown aggregate state of the economy. Under certain conditions, attention and four measures of uncertainty are countercyclical: Agents pay more attention when they expect the economy to be in a bad state, and their reaction generates higher (i) aggregate output volatility, (ii) cross-sectional output dispersion, (iii) forecast dispersion about aggregate output, and (iv) subjective uncertainty about aggregate output faced by each agent. All these phenomena are prominent features of ...

The Role of Dispersed Information in Pricing Default: Evidence from the Great Recession
The recent Global Games literature makes important predictions on how financial crises unfold. We test the empirical relevance of these theories by analyzing how dispersed information affects banks' default risk. We find evidence that precise information acts as a coordination device which reduces creditors' willingness to roll over debt to a bank, thus increasing both its default risk and its vulnerability to changes in expectations. We establish two new results. First, given an unfavorable median forecast, less dispersed beliefs greatly increase default risk; this is consistent with ...

Attention and Fluctuations in Macroeconomic Uncertainty
I show that economic agents’ attention to macroeconomic events can increase macroeconomic uncertainty during recessions. Agents face uncertainty about the aggregate state of the economy, receive dispersed information about it, and can pay attention to acquire more information. When the economy is in a bad state, agents choose to pay more attention, and their collective response increases three common measures of uncertainty: (i) aggregate output volatility, (ii) forecast dispersion about output, and (iii) subjective uncertainty about output. Uncertainty driven by agents’ attention implies ...
