Traders and finance: Daniel Beunza - Associate Professor in the Cass Business School at City, University of London, talks to Laurie Taylor about his study of a Wall Street derivatives-trading room. In particular, he explores how the extensive use of financial models and trading technologies over recent decades has exerted a far-ranging influence on Wall Street , one which should alert us to the risks of moral disengagement caused by a dependence on ‘models’. Also, Anastasia Nesvetailova, Director of City Political Economy Research Centre at City, University of London , argues that financial malpractice is not an anomaly, but part of a business model of finance which involves the sabotaging of competitors, clients and even the state.
