The Slow Recovery in Output after 2009. James Stock, 2017, Paper, “The U.S. economy has been expanding slowly since the recession trough in 2009. Though unemployment has declined at about the same rate as in previous recoveries, output has grown much more slowly than in the past. We explore explanations for the shortfall in output growth, using a quantitative decomposition based on growth economics. Two components of the decomposition stand out: slow growth in productivity, and a growing shortfall of labor-force participation relative to its demographic determinants. The slow growth in both components predated the recession. Our analysis gives a full treatment to cyclical effects.Link
