The title is from a new paper by Aaron Chatterji, Edward Glaeser, William Kerr, available here, about local entrepreneurship (disclosure: the Kauffman Foundation supported the conference at which this paper was presented). When I talk to entrepreneurs about policy, they comment that they wish they knew more about what to do at the local level. Successful entrepreneurs will frequently be tapped by local policy makers for their input or to give a speech, and they sometimes feel overwhelmed or at a loss for words when it comes to talking about local government policy.
This paper reviews the literature on this subject and plainly stated it is excellent. I recommend it to a wider audience because it is not only good, but written in plain english, unlike many academic papers. I will read this multiple times, as it serves to refresh my memory on some papers and inform me about new literature I'm not familiar with yet.
Hat tip to Robert Strom for pointing this paper out.
