The Case for Competitive Government
What is missing is the political demand for tests of what really works. Too many policies on education, welfare and criminal justice are just so much homeopathy: cute-sounding stories about what works leaning more on faith than on evidence. Politicians and civil servants, faced with some fancy new idea, should get into the habit of asking for a proper randomised trial. And we, as citizens, should be equally demanding.
In fact, the political system is very ill-suited to trial and error learning. That is what markets are for. That is why I favor competitive government.
Thanks to Mark Thoma for the pointer.
