United States Tax Rates and Economic Growth

Abstract

American politicians aim to create economic activity that will expand the economy and provide opportunities for citizens. Today (in 2022), President Joseph Biden presents an ambitious tax plan to grow the economy and provide for more equal opportunities. With Biden’s aim for a tax increase, this research examines the impacts of tax and other economic variables on economic wellbeing. In turn, this research provides a timely update on contributing factors to economic growth. Previous academic research shows the impacts of tax rates and common economic variables related to U.S. economic growth. We gather data from 1960 to 2020 to explore U.S. real gross domestic product (GDP) per capita. Through a series of multiple regression models, we find that increases in the highest statutory corporate and personal income tax rates reduce real GDP per capita. Growth in net exports of goods and services, M2 money supply, multifactor productivity and cost, collectively increase real GDP per capita, while, the personal savings rate, and the market value of gross federal debt decrease real GDP per capita. We recommend that if Congress elects to raise tax rates, it should start with the personal income tax rate.
