I’ve finally had a chance to look over a book published last year by the London-based Institute for Economic Affiars: The Profit Motive in Education–Continuing the Revolution. It turns out to be a great overview of current developments from all over the world, and has a particularly useful chapter by its editor James B. Stanfield, development director at the E. G. West Centre at the University of Newcastle, founded by James Tooley.
I highly recommend it to anyone interested in better understanding how genuine markets can and do work in elementary and secondary education. Delightfully, the whole thing is available on-line as a .pdf file (see link above). E-mail it to your Kindle!
