Sure. I'm familiar with Dominique's work. I think the issue there, as I understand it, is that it's just very difficult to know....
As I said, if you think about the process, the employer advertises a vacancy at a particular wage. If no one applies, or no one suitable applies, then they can approach the federal government for a temporary foreign worker. I think the issue is how we decide whether that wage is appropriate or not.
My understanding of Professor Gross's idea is that if we had better information, then we'd have a better estimate of what that local wage is for that particular occupation. I'm sure we could improve in that regard, but I think it's also a difficult thing to do.
