Summers, Lawrence H. "Have We Entered An Age Of Secular Stagnation?" IMF Economic Review 63.1 (May 2015): 277-280.

Abstract

Since the depths of the financial crisis in 2008-2009, most financial indicators have stabilized. However, the real parts of the economies in the industrialized world continue to lag. In this 2013 speech, I suggested that an older idea of 'secular stagnation' may help explain the disappointing recent economic performance.
