Belief Disagreement and Portfolio Choice
Published: 09/18/2022 | DOI: 10.1111/jofi.13179

Using proprietary financial data on millions of households, we show that likely‐Republicans increased the equity share and market beta of their portfolios following the 2016 presidential election, while likely‐Democrats rebalanced into safe assets. We provide evidence that this behavior was driven by investors interpreting public information based on different models of the world. We use detailed controls to rule out the main nonbelief‐based channels such as income hedging needs, preferences, and local economic exposures. These findings are driven by a small share of investors making big changes, and are stronger among investors who trade more ex ante.
Household Portfolios and Retirement Saving over the Life Cycle
Published: 08/12/2025 | DOI: 10.1111/jofi.13473

Using account‐level data on millions of U.S. middle‐class investors over 2006 to 2018, we characterize the share of investable wealth that they hold in the stock market over their working lives. Relative to the 1990s, this share has both risen by 10% and become age‐dependent. The Pension Protection Act (PPA)—which allowed target date funds (TDFs) to be default options in retirement plans—played an important role: younger (older) workers starting at a firm after TDFs became the default option post‐PPA invested more (less) in stocks, in line with the TDF glidepath. In contrast, contribution rates changed little following the PPA.
