Gen. Martin Dempsey took a cautious approach to U.S. involvement in Afghanistan and Syria. He did not approve of the way Gen.

Under his command the U.S. limited its role in Afghanistan and Iraq and handed more responsibility to local forces. Gen. Dunford who succeeded Dempsey as chairman Joint Chiefs of Staff for the U.S. follows the cautious approach set by Dempsey. Dempsey's approach extends to what he believes is an Heisenberg effect in physics where when you you observe or touch something it changes the way it functions and operates.

Spain's central bank was lauded for macroprudential supervision before the housing bubble burst. Will China's central bank and financial authorites which have managed the housing bubble upto this point face similiar problems?

Chinese buyers invest in homes because low interest rates on savings accounts cannot keep up with inflation. Real estate investment was 13% of GDP in 2011. Home ownership is a recent development in China, only since 1990, Chinese have never experienced large price declines. Household debt as a percentage of disposable income has increased significantly in recent years, up to 53.6% in 2011 from 31.3% in 2008, according to Lardy.
