Some investors are worried that fighting in the Middle East and the stalemate between Russia and the west could threaten the U.S. economy. This week on Money Talking, regular contributors Joe Nocera from the New York Times and Rana Foroohar from Time magazine discuss how these and other events happening abroad could affect U.S. economic growth. Plus, inversions. More U.S. corporations are rushing to "invert," or incorporate in another country with lower tax rates. Money Talking discusses whether this spate of inversions could inspire Congress to change the tax code.
