Nicholas Crafts has just posted a piece on Vox, which examines policy lessons from past severe recessions (click here). In particular, he looks at the recessions of 1930-32 and 1979-81. Among other things, he advocates stimulating private house-building as the stock of houses is estimated to be three million below the long-run equilibrium. Tim Besley and Tim Leunig have some radical suggestions as to how this can be achieved - click here. Of course, the impact of this policy will be to drive down house prices, and, in the process, raise defaults on mortgages, further damaging bank balance sheets.
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.
