Writing good exam questions is hard. If done correctly, the student should have no idea the lengths you went through to write a good set of questions. But maybe they should know just how difficult it really is. This semester I tried an experiment: allow my masters students a chance to write their own midterm exam (with some pretty specific guidelines). We’ll see how it turns out, but so far I have been impressed with how much they have taken to the idea.
I recently had the pleasure of writing a blog post for the London School of Economic’s US Centre Blog. It covers a recent publication in State and Local Government Review on the implications of overlapping local governments on local public employment in the US. You can find more information about this piece here. See below for the full text of the post as well as a link to the original.
