The markets responded positively to the news last week of a euro zone deal to try and turn around their two-year financial crisis. Marcus Mabry, editor-at-large of the International Herald Tribune, which is the international edition of The New York Times, tells us how he expects the markets to continue to go this week and to be on the lookout at Italy, which could be the next euro zone country to be in financial trouble. Charlie Herman, business and economics editor for WNYC and The Takeaway, looks at the upcoming G20 Summit in France this week, and if they can come up with a framework to deal with Europe’s economic troubles. Markets will turn their attention to the U.S. as a number of key economic events are set to happen, including unemployment figures for October, a policy meeting by the Federal Reserve and Fed Chairman Ben Bernanke’s quarterly news conference. Also on the agenda, the U.N. will officially announce today that the world population has reached 7 billion people. How will this affect the world’s energy and environmental challenges?
