Riskless interest rates fell in the wake of the financial crisis and have remained low. We explore a simple explanation: This recession was perceived as an extremely unlikely event before 2007. Observing such an episode led all agents to re-assess macro risk, in particular, the probability of tail events. Since changes in beliefs endure long after the event itself has passed, perceived tail risk remains high, generates a demand for riskless, liquid assets, and continues to depress the riskless rate. We embed this mechanism in a simple production economy with liquidity constraints and use observable macro data, along with standard econometric tools, to discipline beliefs about the distribution of aggregate shocks. When agents observe an extreme, adverse realization, they re-estimate the dis...

The Great Recession was a deep downturn with long-lasting effects on credit markets, labor markets and output. While narratives about what caused the recession abound, the persistence of GDP below its pre-crisis trend is puzzling. We propose a simple persistence mechanism that can be easily quantified and combined with existing models, even complex ones. Our solution rests on the premise that no one knows the true distribution of shocks to the economy. If agents use observed macro data to estimate this distribution non-parametrically, then transitory events, especially extreme events, generate persistent changes in beliefs and thus in macro outcomes. We apply our tool to an existing model, designed to explain the onset of the great recession, and find that adding belief updating endogenous...
