The Keynes Society hosted its most logistically demanding meeting ever. The title of the event was 'No More Business as Usual: How to Avoid Another Financial Crash'. In front of a packed crowded of 550, including 30 visiting schools, Ha-Joon Chang, Ann Pettifor, Paul Ormerod and Crispin Odey debated the causes of the 2008 crash, the lessons that have been learnt and how future crashes can be avoided. The 2008 crisis marked a sea-change point. It was a failure on three counts: (1) a failure of regulation, (2) a failure of modelling and (3) a failure of ideology. Underpinning the crisis was the fundamentally flawed neoliberal ideologue which has dominated mainstream economic thinking.
