Jonathan Gruber was one of the Obama administration's key advisers during the health-care reform debate. As the economist who conceived the ideas at the heart of the Massachusetts health-care law, he is arguably the intellectual godfather of the Affordable Care Act. All of which would make him a natural fit for the Independent Payment Advisory Board, the new, 15-member panel that has the authority to reduce Medicare doctors' reimbursements and pilot new ways to deliver high quality care for less. There's just one tiny problem: Gruber has absolutely no interest in serving on the panel. "No way," he says without pause. "Maybe if it was a part-time gig. But full time? I can't see it."
