I think you guys should add a course (yes a whole course) on Health Economics.
It is a huge topic but also a very important/applicable one. Most economics schools that I've seen have a whole class to study Health Economics. Usually it is taught as an upper-level course but so are Developmental Economics and International Finance and you already have courses on those. It is a very highly debated topic - often argued by people who have no idea what they're talking about and could use some education!
