The Canadian Economics Association is offering a three-day summer course on panel data, taught by Wooldridge and Imbens. You may have heard of these people. If not, suffice it so say they're at the top of the pyramid. It will be held just before the yearly conference in Toronto.
Anyway, I was about to register for it when I noticed the tuition refund is not made available to students studying outside of Canada, which increases the price by a factor of ten. Now I'm no longer sure it's worth it for me, but any other Canadian doctoral students who aren't that far removed from Toronto should check it out.
Oh, and if you'll be at the conference or the course, post!
