Thank you to both of you for being here today.
Dr. Dawson, I wanted to ask you about the border tax suggestion that's been made by some American policy-makers. You have said of the border tax that it “makes no logical or economic sense. It's complicated and may not deliver what [the U.S.] wants, and may result in retaliatory tariffs of up to $100-billion from trading partners.” Furthermore, you've made the point that those who would be hit hardest are low-income Americans. I wonder if you could expand on these points.
