Contributing to interdisciplinary debates in cultural economy and the social studies of finance, and grounded in extensive empirical research, this book offers an innovative analysis of how the contemporary global financial crisis was governed. The focus is on the US and UK between 2007 and 2011 If you wonder, like everyone does, why the most severe financial crisis in living memory has not produced a fundamental change in the way we regulate economies and understand the role of banks, read this book. Drawing on an original reading of Deleuzes notions of modulation and mitigation, Langley shows in an empirically detailed manner how crisis response was driven by ad-hoc initiatives, minor modulations and sometimes conflicting approaches that were largely oriented toward rebuilding affective atmospheres of trust. Steering away from grand conceptions of neoliberalism, Langleys attentiveness to the situated contingency of crisis management brings the politics back into our understanding of financial regulation.
