Rebuilding Haiti: Mangos, Tourism and Garment Factories

The massive earthquake that struck Haiti nearly three weeks ago has left development economists and international aid workers scrambling for the best way to rebuild the country. Some want the United States to take the lead in a Marshall Plan-type recovery program, while others advocate leaving Haiti alone as much as possible. We find out how Haiti might best rebuild — and how the international community can help. Paul Collier is a professor of economics and director of the Center for the Study of African Economies at Oxford University and the author of "The Bottom Billion: Why the Poorest Countries Are Failing and What Can Be Done About It." He was a special adviser on Haiti to the United Nations secretary general in 2009.
