Richard Thaler and Cass Sunstein's book Nudge (see yesterday's post) has had a substantial impact on the current British government. Apparently, the entire cabinet was given it as a summer reading assignment. The idea behind Nudge is that public policy should nudge people to make socially-optimal decisions by thinking cleverly about the choice architecture facing citizens. The UK government now has a Behavioural Insights Team (or Nudge Unit) which apply the insights from behavioural economics to public policy in the UK. Their blog is available here and a recent critique of the unit is here.
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.
