In 2004 he became a Research Fellow of the Institute for the Study of Labor. According to the British Academy Keynes Lecture, delivered in September 2005, he argued "In what follows we shall, among other things, argue that there has not been a spending boom, the non-spending boom was not credit-fuelled and there has probably not been a house price bubble."

In June 2007, when interviewed on the state of the UK housing market he was quoted as saying, "It might settle back a little, or remain relatively flat for a bit, but I don't think there's any fundamental overvaluation. Over the next few years it might keep on edging upwards." In a February 2008Bloomberg News interview, he said: 'The actual size of the downturn is minute, how big is it going to be? I don't know, but it won't be very big.' The Bank of England estimated that by Q1 2009, due to declining house prices, 7% of owner-occupied mortgagors were in negative equity, equivalent to around 700,000 households.
