The book itself has not yet come to my pile, though perhaps it still will. This one is self-recommending, so here is the basic information, it is due out June 2:
Alvin Roth, Who Gets What — and Why: The New Economics of Matchmaking and Market Design.
If you do not know why this is self-recommending, here are previous MR posts on Alvin Roth. And here is the book’s home page.
