President Barack Obama's plan to raise the minimum wage to $9 a hour from $7.25 would help the economy, one of his former top economic advisors says.
"I think our country will do a lot better if we have more shared prosperity," Princeton economist Alan Krueger told CNBC's "Closing Bell" on Tuesday.

However, James Pethokoukis, a columnist and blogger for pro-business think tank American Enterprise Institute, holds a different view.
"While hiking the minimum wage might not cost current jobs, there is evidence it hurts future hiring," Pethokoukis said in an email to CNBC.com. "Most economist think wage subsidies would work better and be less distortive to labor markets, but politicians prefer minimum wage laws because business rather than taxpayers foot the bill—at least directly."
