Can principles-based tax and spending reforms cut deficits and raise GDP?
Core argument: The authors estimate that 13 illustrative tax and spending reforms would cut federal budget deficits by 38% over 30 years relative to current law, while growing the capital stock by 31%, GDP by 21%, and wages by almost 7%.
Expanding federal debt presents an opportunity to rethink U.S. federal fiscal policy while growing the economy and enhancing social insurance. We present illustrative fundamental reforms of federal tax and spending programs consistent with standard design principles that have emerged over time in the field of public economics. Specifically, we analyze 13 major tax and spending reforms that include a full accounting of their budgetary and economic interactions, arguably one of the most ambitious computational public finance experiments performed to date. Over the next 30 years, relative to current law, these reforms: (i) reduce federal budget deficits by 38%; (ii) grow the capital stock by 31%, GDP by 21%, and wages by almost 7%; (iii) reduce health insurance premiums by 27%; (iv) produce almost universal health insurance enrollment along with improvements in average health and productivity; (v) reduce old-age poverty; and (vi) reduce carbon emissions, relative to current law. These changes improve the welfare of many current and all future generations.
