David Chambers and Elroy Dimson have done a lot of nice work looking at how Keynes invested the endowment of King's College, Cambridge - click here for their working paper. David was interviewed for the BBC2 programme on Keynes which aired yesterday evening (click here). You can also listen to him talk about Keynes the investor in the video clip below.
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.
