PWBM Projections In-Line with Official Government Estimates

In the Congressional Research Service’s report on the economic effects of the 2017 tax bill, Senior Specialist in Economic Policy Jane Gravelle and Specialist in Public Finance Donald Marples analyzed the effects of the Tax Cuts and Jobs Act (TCJA) on output and growth.

Federal Debt Still Matters

Lower interest rates since 2008 have reduced the cost of federal debt per dollar relative to the period before 2008. However, PWBM projects that the sheer size of federal debt will reach 190 percent of GDP by 2050 under present law. Even with low borrowing rates, stabilizing the debt-to-GDP level at its current value could increase GDP in 2050 by one to three times more than the projections we previously provided for the 2017 Tax Cuts and Jobs Act.

Tariff’s Projected to Raise Prices for Americans

The New York Times’ Jim Tankersley cites PWBM in an explanation of how Trump's tariffs erase the benefits of the current tax cuts. In particular, Tankersley finds that the benefits of Trump's tax cuts to the lower and middle classes will likely unwind as a result of his tariffs on goods from China, Mexico, and Europe.

Seven U.S. Economic Models Project Rapid Growth of Federal Debt

At the National Tax Association Spring Symposium, PWBM participated in a roundtable with other economic modelers. All modelers showed the results of cutting Social Security benefits by one-third in 2031. All models found that even with a benefit cut, by mid-century the U.S. still has a sizable debt-to-GDP ratio.

Annual Data is Better than Monthly for Understanding Tax Revenues

FactCheck.org’s Eugene Kiely explored how to think about the impact of 2017’s Tax Cuts and Jobs Act (TCJA) on tax revenue through official measures of tax receipts. Treasury reports show that in 2018 tax receipts were slightly lower than in 2017. However, tax receipts in February 2019 were 10% higher than in February 2018. Kiely asked PWBM’s Alexander Arnon what these figures mean for future tax receipts.

Meanwhile, policy analysts continue to debate the details.

Growth in Business Investments Tied to Oil Prices, Not Tax Cuts

The New York Times reported Tuesday that the Trump Administration’s “rosy” outlook on the U.S. economy is “increasingly diverging” from economists’ forecasts. The White House predicted that the economy will continue to grow at 3 percent through 2024 (adjusted for inflation), while the Congressional Budget Office (CBO) released their forecasts standing at 2.3 percent for 2019, slowing to 1.7 percent in 2020. Meanwhile, the Federal Reserve’s forecast also predicts 2.3 percent growth in 2019, and Goldman Sachs suggested a more conservative 2.1 percent growth this year based on consumer confidence figures and regional business surveys.

The Hidden Revenue Cost of a 70% Top Marginal Rate

In a recent interview on 60 Minutes, Congresswoman Alexandria Ocasio-Cortez presented the idea of instituting a 70 percent marginal tax rate on income over $10 million. Many commentators have weighed in on this proposal, both with op-eds supporting and criticizing this type of policy.

A conventional revenue estimate of the new tax rate would incorporate a traditional elasticity of taxable income. However, a second factor is very important for high-income taxpayers: a significant share of income above $10 million is earned by owners of pass-through businesses. We project that a significant amount of pass-through business owners will respond to this tax by reorganizing as C corporations to minimize their tax liability. This shift could cause the new 70% tax rate to lose as much as 43 percent of revenue that would otherwise be raised.

The Price of Oil is Now a Key Driver of Business Investment

US production of crude oil has more than doubled since 2008. Starting in the mid-2000s, the application of horizontal drilling and hydraulic fracturing to tight oil formations led to a surge in US supply known as the shale boom. In this post, I discuss the shale boom’s impact on the relationship between business investment and the price of oil. I then estimate the effect of the recent rise in oil prices on investment in 2018. I find that oil prices might even account for most of the increase in the growth rate of investment in 2018.

A Response to the White House’s Recent Critique of PWBM’s Tax Analysis

This past Friday, Dr. Kevin Hassett, Chairman of the Council of Economic Advisers, critiqued Penn Wharton Budget Model’s analysis of the “Tax Cuts and Jobs Act” (TCJA), signed into law by President Trump in December 2017. Dr. Hassett delivered his remarks at the 2019 American Economic Association meeting. The AEA meeting is the largest annual event of academic and government economists, held this year in Atlanta, Georgia.

Marriage Matters for the Gender Pay Gap Among Self-Employed

The rise of the ‘gig economy’ means that understanding patterns of self-employment is more important than ever for designing tax benefits and subsidies that affect business activities. In fact, self-employment represents as many as 1 in 5 jobs.

We find that gender differences in self-employment patterns are mostly driven by the differences across marital status. Married women are more likely to be self-employed than single women. On average, self-employed married women work fewer hours than men and single women, regardless of employment type, and married women who are employer-employed. These differences carry over to earnings.
