Do governments do better than markets? Obviously, it depends. For example, when it comes to charter schools, which is a form of quasi-privatization of schooling, the evidence shows that they are not better than public schools, e.g. https://www.nber.org/papers/w22502  #mssp668 https://twitter.com/chelseayish/status/1318403988232957952

On the other hand, introducing competition within the National Health Service system in the UK improved management practices and hospital performance: https://academic.oup.com/restud/article-abstract/82/2/457/1585860 by @johnvanreenen & co-authors. This is not privatization but here aspects of market competition work.

#EconTwitter, in your view, what is the best example of privatization of public services that improved outcomes? @wwwojtekk @Noahpinion @johnvanreenen?

@ne0liberal the above is also a good question for you!
