Not my usual beat, but I've had leadership on the brain lately, thanks to the new Work of Leaders author events that we recently added to the calendar.
Anyway, I just stumbled across a really nice post by Daron Acemoglu and James Robinson over at Why Nations Fail. They summarize two new research articles about leadership, one at the nation-state level and the other at the corporate/CEO level.
I won't give away the punchline, but it's a good piece. Go read it.
