Disaster insurers: Laurie Taylor talks to Rebecca Bednarek, Senior Lecturer in Management at Birkbeck, University of London, about a study into a global re-insurance market in which 'Acts of God' provide formidable opportunities for financial markets. Also, amateur traders: why do they risk so much for so little? Alex Preda, Professor of Accounting, Accountability and Financial Management at King's College, London, explores how ordinary people take up financial trading in a world far removed from the glamour and wealth of investment bankers. They're joined by Dan Barnes, the business journalist.
