Doug Hall, director of the liberal Economic Policy Institute, estimates that raising the minimum wage to $9 would pump $21 billion into the economy and lead to the creation of 120,000 jobs.
But Randel Johnson, vice president at the U.S. Chamber of Commerce for labor issues, said the increase would come "on the backs of employers" who would hire fewer people and cut overtime.
"You don't put new burdens on employers when they are trying to recover in a tough recessionary time," he said.
Johnson also warned against tying wage increases to inflation.
"Employer profits are not magically indexed somehow to always go up," Johnson said. "Congress needs to look at the validity of raising the minimum wage in the context of the economic times in which it's being proposed."
That concern is expected to drive Republican opposition in Congress. Florida Sen. Marco Rubio, who delivered the GOP response to Obama's State of the Union address, said Wednesday that boosting the minimum wage is the wrong way to help workers increase wages.
"I don't think a minimum wage works," Rubio said on "CBS This Morning. "I want people to make more than $9 dollars an hour. The problem is, you can't mandate that."
Boehner, the House speaker, told reporters Wednesday: "When you raise the price of employment, guess what happens? You get less of it."
The White House is pointing to companies such as Costco, Wal-Mart and Stride Rite that have supported past increases in the minimum wage, saying high wages help build a strong work force and lower turnover helps improve profitability over the long run.
