Al Roth is basically a computer scientist masquerading as an economist (or the other way around?) -- he does a lot of work on stable matching algorithms, including involvement in designing the medical residency match, kidney-donation match centers, and Boston public school assignments. If you haven't heard of him, you should definitely read a profile. Shapley also won--I don't know much about him, but I'm sure his theoretical contributions are the underpinning for all later work in the area, he's a giant of the field, etc. etc. etc.
