Deposit withdrawals in Greece have been substantial over the past two years. However, the failure of Greece's politicians to form a coalition government has resulted in deposit withdrawals accelerating - click here and here for more on this. Depositors are rightly concerned about the exit of Greece from the euro and the subsequent devaluation of their deposits. The puzzle for me and many others is why are there so many deposits still remaining in the Greek banking system. One reason is that the Greek banking system is being kept alive by massive injections of money from the ECB. Will the ECB continue to support the Greek banking system in the face of a mass withdrawal of deposits? I doubt that there is the political will in Germany for this as the Bundesbank already has a huge exposure to Greece (as well as Spain and Italy) through the ECB's internal Target 2 system.
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.
