A Financial Times report published today reveals the high level of equity withdrawal in the run up to the credit crunch in the summer of 2007. It is particularly worrying that equity withdrawal was highest in some of the poorest regions of the UK. Northern Ireland comes out top of the bunch - 74% of those re-mortgaging their properties in the province in 2007 withdrew equity. As a result, those who extracted large amounts of equity may owe more on their mortgage than the actual value of their property even though they bought their home well before the bubble began.
My colleague and former PhD student Gareth Campbell has created a website about the British Railway Mania - click here . This episode has been described by the Economist as probably the greatest bubble in human history. Gareth's website provides background on the Mania and posits some explanations for the 'bubble'. In his explanation of why the bubble happened, Gareth places a lot of emphasis on investor myopia regarding future dividends and uncalled capital. His study of investors during the episode does not support the view that this episode was fuelled by naive and irrational investors.
