Dr Peter Warburton is one of the UK’s leading independent economists and author of an insightful and prescient book Debt and Delusion, first published in 1999, which argued that policymakers and investors alike were becoming complacent about the systematic buildup of debt across the global economy - a deepening problem that finally erupted with devastating consequences in the global financial crisis of 2008. Now eight years on from that crisis, he has revised and updated his research and in an exclusive interview discusses his latest findings.
