How much can demographic changes account for trends in the U.S. economy? This paper shows that a heterogeneous-agent, overlapping-generations model with historical demographic flows can generate several features of the U.S. economy over the past several decades, including a secular decline in economic growth, a rise in savings relative to GDP, a corresponding decline in real interest rates, and, in part, changes in wealth inequality.

Analysis of Federal Reserve survey data released in September 2020 shows that U.S. wealth inequality has declined for the first time in 30 years.

In an economy with heterogeneous firms and heterogeneous consumers, the authors describe a general equilibrium where firm equity is priced by a supply and demand process. With a model robust to arbitrary, nonlinear tax functions, they investigate the efficiency of replacing the current U.S. tax regime with a policy of no corporate taxes and taxation of capital distributions to the household at progressive personal income tax rates.
