I got tuition remission and a 19.2K assistantship for four years. I'm told the assistantships are officially teaching assistantships "which can involve anything from grading, to running discussion sections to (in 3rd or 4th years, but only if the student wants to do this) teaching their own classes," and that sometimes profs use TAs as RAs too. I'm managing my expectations about the other schools - not super optimistic. But I'm very happy for this great deal with American. Teaching in the third and fourth year? Maybe I'm being naive, but it seems like it would be a great advantage in the job market to have that. There are a few summer fellowships and some dissertation funding I'm looking into as well, but that'll be something to worry about in a little while - not now.
Still crossing my fingers on the others, but I think American University would be very good environment - lots of good history of thought, lots of good economic history, and still a place I can do the macro, labor, and monetary work I'm interested in.
