This week's Economist has a really nice section on the growth of inequality (click here). Many parts of the developed (and emergent) world have experienced growing wealth and income inequality over the past three decades. My own work on Ireland shows that wealth in the 19th century was concentrated in the hands of the top 1% of the population, but from 1900 onwards wealth became less concentrated. However, since the 1980s, wealth has become much more concentrated. The big questions arising from this for economists and other social scientists are why has this happened and what can we do about it?
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.
