In What Went Wrong? An Agenda for the G20, leading financial analyst Miles Saltiel, argues that many common explanations for the economic crisis are wrong, stemming from prejudice rather than evidence. He identifies five key culprits that the G20 should focus on instead: (1) loose monetary policy; (2) hubristic social engineering in housing policy; (3) the failure of the Basel protocols on core capital; (4) banks that were 'too big to fail'; and (5) the effects of oligopoly on auditors and ratings agencies.
