Since its intellectual inception in the 1930s and its political emergence in the 1970s, neo-liberalism has sought to disenchant politics by replacing it with economics. This agenda-setting text examines the efforts and failures of economic experts to make government and public life amenable to measurement, and to re-model society and state in terms of competition. In particular, it explores the practical use of economic techniques and conventions by policy-makers, politicians, regulators and judges and how these practices are being adapted to the perceived failings of the neoliberal model.
