Capital income inequality is large and growing fast, accounting for a significant portion of total income inequality. We study its growth in a general equilibrium portfolio choice model with endogenous information acquisition and heterogeneity across household sophistication and asset riskiness....

What contributes to the growing income inequality across U.S. households? We develop an information- based general equilibrium model that links capital income derived from financial assets to a level of investor sophistication. Our model implies income inequality between sophisticated and...

We show that capital income inequality is large and growing fast, accounting for a significant portion of total income inequality. We study its determinants in a general equilibrium portfolio choice model with endogenous information acquisition and heterogeneity across household sophistication...
