Licensing occupations: Ensuring quality or restricting competition?

"Morris Kleiner has produced the most thorough evaluation of the effects of occupational licensing in years, perhaps ever. In a rational world, this book would provoke interest by policymakers and the public in reconsidering where occupational licensing is beneficial for society, and where it is beneficial for those lucky enough to be granted licenses but not for society as a whole." -Alan B. Krueger, Princeton University.
