How Does Accounting for Population Change Affect Estimates of the Effect of Immigration Policies on the Federal Budget?

We report estimates from the Penn Wharton Budget Model (PWBM) that exempting employment-based green cards from statutory limits for applicants (and their families) who have earned a doctoral or master’s degree in a STEM field---similar to Section 80303 in H.R. 4521---would reduce federal budget deficits by $129 billion from 2025 to 2034. In contrast, a conventional budget estimate, which would include projected increases in federal spending but not the effect of a larger population on federal tax revenues, shows an increase in federal deficits of $4 billion.

Explaining the Rise in Prime Age Women’s Employment

The economic costs of the COVID-19 pandemic were widely expected to fall disproportionally on women. Instead, the employment rate of prime age women recovered faster than men’s and rose to its highest point in U.S. history in 2023. We show that the resilience of women’s employment is driven by two long-term trends that predate the pandemic and continued through it: 1) the growing share of women who are college graduates, and 2) the rising labor force participation of college-educated mothers with young children.

Why are Changes to IRS Funding Always Scored as Increasing the Deficit?

The House of Representatives is considering legislation that would rescind $14.3 billion of IRS funding as a budgetary offset for a package that provides aid to Israel. CBO estimates that the decrease in IRS funding alone would reduce revenue by $26.8 billion over 10 years, increasing the deficit by $12.5 billion. Due to scoring conventions, CBO’s projected deficit increase could not be reversed for any future legislation that adds the $14.3 billion in funding back to the IRS.

Pillar Two and the U.S. A Policy Explainer for Navigating the Global Minimum Tax

The OECD expects countries to implement components of Pillar Two, its framework for a global minimum tax, starting in 2024. The US is likely to cede tax rights to foreign jurisdictions if it does not enact new tax law. Pillar Two will likely reshape the nature of tax competition between countries, incentivizing greater use of subsidies and refundable tax credits to counteract higher statutory rates.

Pillar Two and the U.S.: A Policy Explainer for Navigating the Global Minimum Tax

The OECD expects countries to implement components of Pillar Two, its framework for a global minimum tax, starting in 2024. This paper provides policymakers with a comprehensive resource for navigating the Pillar Two framework. We review key components of Pillar Two and related aspects of US tax policy, including: (i) how the global minimum tax is likely to expose portions of the current US corporate tax base to new foreign taxes; (ii) potential modifications to US tax law that would increase compliance and protect US tax rights; and, (iii) the extent to which Pillar Two is likely to succeed in its policy objectives of reducing corporate profit shifting and international tax competition. The US is likely to cede tax rights to foreign jurisdictions if it does not enact new tax law. Pillar Two will likely reshape the nature of tax competition between countries, incentivizing greater use of subsidies and refundable tax credits to counteract higher statutory rates.

When Does Federal Debt Reach Unsustainable Levels?

PWBM estimates that---even under myopic expectations---financial markets cannot sustain more than the next 20 years of accumulated deficits projected under current U.S. fiscal policy. Forward-looking financial markets are, therefore, effectively betting that future fiscal policy will provide substantial corrective measures ahead of time. If financial markets started to believe otherwise, debt dynamics would “unravel” and become unsustainable much sooner.
