Contributor(s): Ruchir Sharma | In this talk Ruchir Sharma will discuss his new book, Breakout Nations. After a decade of rapid growth, the world's most celebrated emerging markets are poised to slow down. Which countries will rise to challenge them? To identify the economic stars of the future we should abandon the habit of extrapolating from the recent past and lumping wildly diverse countries together. We need to remember that sustained economic success is a rare phenomenon. Ruchir Sharma is the head of emerging markets at Morgan Stanley and a longtime columnist for Newsweek, the Wall Street Journal, and the Economic Times of India. He lives in New York City.
