Central banks around the world have engaged in unconventional monetary over the past five years. Quantitative Easing (where central banks create money to buy long-dated governments bonds or even mortgage-backed securities) and forward guidance (where central banks commit to low interest rates until certain criteria are met) are the new tools in the central banking tool-kit. However, many commentators are concerned about the distributional consequences of these policies i.e., that they benefit Wall Street at the expense of Main Street. Indeed, in this WSJ article, the Fed's former main Quantitative Easer argues that Fed has been captured by Wall Street banks and is pursuing these unconventional policies at their behest. In other words, the Fed is no longer an independent central bank! Click here for an op-ed by Raghuram Rajan, the Governor of the Reserve Bank of India, on unconventional monetary policy.
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.
