In 2007, the World Bank was in crisis. Some saw conflicts over its leadership. Others blamed the institution itself. When the International Bank for Reconstruction and Development, the cornerstone of what became the World Bank Group, was founded in 1944, poor and war-torn countries had little access to private capital.

"The time when middle-income countries depended on official assistance is thus past," Jessica Einhorn, a former managing director of the World Bank wrote in these pages in 2006, "and the IBRD seems to be a dying institution." In roundtable discussions and op-ed pages, the question was the same: Do we still need the World Bank?
