Raghuram G. Rajan hired by India's government

In August, Mr. Singh, who has frequently sought Mr. Rajan’s advice, called and asked him to take a leave from his job as a professor at the University of Chicago to return to India, where he was born, to help revive the country’s flagging economy. Within weeks, he was at work as the chief economic adviser in the Finance Ministry.... 

Mr. Rajan, 49, became famous in the economics profession for his prescience in warning about the growing risks in the financial system at a Federal Reserve conference in 2005, three years before the failure of Lehman Brothers. He argued that innovations and deregulation appeared to have made the global financial system riskier, rather than safer and more stable as many economists and top policy makers like Alan Greenspan then believed. 

The son of an Indian diplomat, Mr. Rajan grew up around the world and in New Delhi, earning degrees from prestigious Indian universities before studying economics at the Massachusetts Institute of Technology. His first big policy job came when he was appointed the chief economist of the International Monetary Fund. Since 2008, he has been an external adviser to Mr. Singh, who is his highest-placed champion in India and who also asked him to lead a committee to propose changes to the country’s financial system.
