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.
In this working paper, the author examines the economic effects of enacting a proposal by the Biden administration to tax long term capital gains at ordinary income tax rates for those with taxable income above $1 million and tax unrealized gains at the time of death for single (joint) filers with more than $1 million ($2 million) in unrealized gains.
A similar version of the report was prepared with the financial support of the Center for Freedom and Prosperity Foundation.
In this background document, the authors provide some information on the choices of key parameter values used in the Diamond-Zodrow model. They focus on parameters involving labor supply, saving, international capital flows and substitution among factors of production.
Given that policymakers will eventually need to decide how to resolve the social security program’s projected shortfall, this paper presents a simulation-based approach to evaluating the conventional alternatives of adjustments to benefits or taxes.
The authors analyze the carbon emission, energy market and economic implications of carbon tax proposal introduced by U.S. Rep. Carlos Corbels (R-Florida). The working paper was released as part of a collaboration between Columbia University’s Center on Global Energy Policy, the Rhodium Group and the Baker Institute.
Since the progressivity of the sales tax is difficult to directly measure, this paper introduces an indirect approach combining simulated household income with realizations of consumption behavior from survey data.
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.
