Modigliani Meets Minsky: Inequality, Debt, and Financial Fragility in America, 1950-2016
This paper studies the secular increase in U.S. household debt and its relation to growing income inequality and financial fragility. We exploit a new household-level data set that covers the joint distributions of debt, income, and wealth in the United States over the past seven decades. The data show that increased borrowing by middle-class families with low income growth played a central role in rising indebtedness. Debt-to-income ratios have risen most dramatically for households between the 50th and 90th percentiles of the income distribution. While their income growth was low, ...

Income and Wealth Inequality in America, 1949-2016
This paper introduces a new long-run dataset based on archival data from historical waves of the Survey of Consumer Finances. The household-level data allow us to study the joint distributions of household income and wealth since 1949. We expose the central importance of portfolio composition and asset prices for wealth dynamics in postwar America. Asset prices shift the wealth distribution because the composition and leverage of household portfolios differ systematically along the wealth distribution. Middle-class portfolios are dominated by housing, while rich households predominantly own ...

To Have or Not to Have: Understanding Wealth Inequality
Differences in household saving rates are a key driver of wealth inequality. But what determines these differences in saving rates and wealth accumulation? We provide a new answer to this longstanding question based on new empirical evidence and a new modeling framework. In the data, we decompose U.S. household wealth into its main portfolio components to document two new empirical facts. First, the variation in wealth by income is mainly driven by differences in participation in asset markets rather than by the amounts invested. Wealth differences are a matter of to have or not to have. ...
