According to leading economist Ann Pettifor, one of the few people to predict the 2008 financial crisis, money is not a commodity but a promise. This radical reconsideration of the power of money means that we can reimagine the way the economy works. The Production of Money also examines popular alternative debates on, and innovations in, money, such as "green QE" and "helicopter money." She sets out the possibility of linking the money in our pockets (or on our smartphones) to the improvements we want to see in the world around us.
