A study by the University of Pennsylvania’s Wharton School, using the Penn Wharton Budget Model (PWBM), finds that three modeled versions of the plan would raise deficits by up to $3.5 trillion over 10 years and as much as $12.2 trillion by 2040. The lowest-cost plan modeled in the study — a version that would tax corporate income at 25 percent instead of the GOP’s proposed 20 percent and pass-through income at 28 percent instead of 25 percent, among a host of other assumptions and tweaks — would lose $1.5 trillion over 10 years, or $1 trillion after accounting for economic feedback effects. (The budget adopted by Republicans last week allows for up to $1.5 trillion to the added to the deficit.) The study also found that workers’ wages would increase by about 1.4 percent over a decade, far shy of the estimated benefits being claimed by the White House.
