GDP drives our economies. Stock market indices flood our media and national debates. Statistical calculations define how we deal with climate change, poverty and sustainability. But what is behind these numbers? In this book, Lorenzo Fioramonti sets out to show how numbers have been used as a means to reinforce the grip of markets on our social and political life, curtailing public participation and rational debate. Stuart Astill finds it to be a well written book, blending together knowledge from different fields into a coherent and readable whole. Of interest to economists, statisticians and especially those studying all aspects of power and politics.
