James Buchanan, the Nobel-prize winning economist, died yesterday at the age of 93. Buchanan is most famous for pioneering public choice theory, which advocates the application of economic analysis to public policy and political science. You can read obits here and here. A free primer on public choice theory is available here and a very good encyclopedia entry is here. One of the key insights of public choice is that we should be concerned more about the institutional framework of our political systems rather than the personalities of our politicians.
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.
