Eric Crampton: NZ Initiative expert on whether we should pay blood donors

Record plasma donor numbers aren't enough to meet growing demand, and there's debate over whether compensation is needed to bring figures up. It's National Blood Donor Week, and the Blood Service is looking to recruit another 4000 over the next year.

NZ Initiative expert Eric Crampton joined the Afternoons team to weigh in. LISTEN ABOVESee omnystudio.com/listener for privacy information.
