The Power to Create Money out of Thin Air is a review of Geoffrey Ingham’s book, Capitalism (Polity Press, first published 2008). However, like all the best reviews, it has become a hook on which to hang discussion of the author’s contemporary pet themes. Here, these include primarily, capitalism’s ‘elastic production of money’. However, Pettifor also takes the opportunity to explain why misunderstanding about the creation of money is so widespread, and why orthodox economists are mainly responsible for the confusion.
