What accounts for persistent racial differences in wealth ownership? Previous research has debated the role that differences in asset ownership play in creating and maintaining wealth inequality. I use survey data to model the ownership of seven assets and find that whites are indeed more likely than blacks to buy high-risk, high-return assets. I then use a simulation model to explore the effect that these differences have on the distribution of wealth. I separate the effects of asset ownership from the effects of racial differences in family wealth history, earnings, education, marital behavior, fertility, and other influences on wealth inequality. I find that removing racial differences in asset ownership reduced wealth inequality drastically, but not completely, and that racial differences in educational attainment account for much of the remaining difference. I estimate how changes in historical patterns of portfolio behavior and educational attainment would have reduced inequality, and I explore the implications of these findings for reducing wealth inequality in the future.
