Thank you.
Professor Dehejia, last time you were here, you had an exchange regarding the carbon tax. One of the members mentioned the open letter that many Canadian economists signed on to. You didn't have a chance at the time to respond to that comment in person.
I know that you did submit something in writing, but I think that since you're back and you're here in person, I'll give you a chance to let the committee know your thoughts on that open letter.
