In this video, CNBC's Andrew Ross Sorkin and Lloyd Blankfein, Goldman Sachs chairman & CEO, discuss the global economic outlook. 

From the World Economic Forum:

Thomas J. Sargent and Christopher A. Sims Win the Nobel Prize for Economics

Rational Expectations and the Ability to Distinguish Cause and Effect Empirically

Macroeconomics has long been the theology of economics.  Sargent and Sims tried to take the common sense reality that it is what people expect in the future, not what we currently observe, that drives their decisions.  They developed a type of econometrics (the statistical modeling of economic reality) that would deal with expectations.  In the process they transformed macroeconomics, generally for the better.  This morning the Nobel Prize committee announced they won the Nobel Prize in Economics.

Today central bank credibility is central to economists' thinking about monetary policy.  Guess why.

One drawback of their revolution is that empirical and theoretical models became farther removed from what we can picture in our imagination.  The great oversimplification of the financial sector that Keynes introduced and Hicks the Younger systematized became more imbedded in economists mindset.  We need a revitalization of economists' imaginations to refertilize their mental pictures of the world.
