Build Back Better Would Make It Harder to Fight Inflation

President Joe Biden’s Build Back Better plan is stalled, and the next steps are unclear. Some Democrats are talking about the need for new pandemic-relief measures, even as the White House is reportedly looking at a stripped-down version of the original proposal. Meanwhile, most analysts are giving short shrift to an issue that deserves more thought: how Build Back Better would make it harder to fight inflation.

True, some of the same economists who (presciently, as it turns out) warned last year that the $1.9 trillion American Rescue Plan Act would increase inflation remain worried about inflation. But economists such as Larry Summers and Jason Furman also support Build Back Better.

That’s because the stimulus in Build Back Better is not that big. According to the Penn Wharton Budget Model, a project at the University of Pennsylvania that analyzes the fiscal impact of public policy, it would increase spending by around $250 billion in 2022, mainly due to the big single-year expansion of the child tax credit and the lifting of the cap on the state and local tax deduction. Revenues would rise by around $50 billion, thanks to higher taxes on firms and rich households. This would add a bit less than 1% of GDP to the budget deficit this year, for a total of less than 6% of GDP, compared with a deficit of roughly 15% in 2020 and 13% in 2021.

With reasonable assumptions about how much of this 1% would feed through to demand, and how that increase in demand would divide between output and prices, the modelers conclude that Build Back Better would increase inflation by between 0.1 and 0.2 percentage points this year and next. If the tax and spending changes were made permanent instead of being phased out, as they are in the current bill, the boost to inflation would be a bit bigger.
