question:
Current Governor of the Reserve Bank of India Raghuram Rajan had predicted the crisis in 2005 when he became chief economist at the International Monetary Fund.In 2005, at a celebration honouring Alan Greenspan, who was about to retire as chairman of the US Federal Reserve, Rajan delivered a controversial paper that was critical of the financial sector. In that paper, "Has Financial Development Made the World Riskier?", Rajan "argued that disaster might loom." Rajan argued that financial sector managers were encouraged to "take risks that generate severe adverse consequences with small probability but, in return, offer generous compensation the rest of the time. These risks are known as tail risks. But perhaps the most important concern is whether banks will be able to provide liquidity to financial markets so that if the tail risk does materialise, financial positions can be unwound and losses allocated so that the consequences to the real economy are minimised."
answer:
Who was the current Governor of the Reserve Bank of India that predicted the crisis in 2005?
