Abstract
In the United States, periods of low household wealth have also been periods of high macroeconomic volatility. Our candidate explanation is that low wealth opens the door to self-fulfilling fluctuations. If wealth poor households expect high unemployment, they have a strong precautionary incentive to cut spending, making the expectation of high unemployment a reality. We first document that poor U.S. households cut spending during the Great Recession much more sharply than richer households, consistent with a precautionary interpretation. We then develop a macroeconomic model featuring unemployment risk, and study the link between asset values and the volatility and persistence of precaution-driven fluctuations.
