Measuring the rise of wealth inequality, capital gains, and income inequality

Grant description:

Capital gains are one of the largest components of income at the top of the wealth distribution and play a key role in measuring wealth inequality. Yet capital gains are rarely included in estimates of the wealth distribution in economics, mainly because measurement requires detailed information on the distribution of wealth at the individual security level.

This project will construct a new dataset to directly measure the holdings of public equities and fixed-income assets for all individuals in the United States using internal IRS data from the 1099-DIV and 1099-INT forms, which have not previously been used by researchers. This improved data will allow for more accurate estimates of wealth inequality, including new estimates of top-end wealth inequality. It will also shed light on savings rates across the income distribution and bring to bear new evidence of whether the rich save more.
