World Bank Changes, Understanding Unemployment  Glenn Loury,
professor of social sciences and economics at Brown University,
and Farai Chideya break down the week's economic headlines. This
week, a look at the World Bank leadership change will mean for
African and developing nations, as well as the long-term trends
underlying the U.S. Department of Labor's most recent
unemployment numbers.    And our final headline is economic. The
head of the World Bank, Paul Wolfowitz, is leaving at the end of
next month. He gave his girlfriend a pay raise and the bank
staff called for him to leave. Now the rumor mill is buzzing
over who will succeed him.  The U.S. usually gets to choose the
president of this powerful group. One possible forthcoming
choice, British Prime Minister Tony Blair, who's stepping down
from his post. Now, fortunately Glenn Loury is not in the
running because we need his help making sense of this and our
other economic news. Glenn is a professor of social sciences and
economics at Brown's University
