The graph is a line chart titled "US Business Sector Output and Labor Productivity Gaps, 2005–19." The y-axis, which ranges from -10 percent to 5 percent, plots the four-quarter moving average change in the deviation from trend (gap) for both US business sector output and labor productivity. The x-axis spans the years 2005 to 2019. The NBER-dated 2007–09 recession is also shaded. The change in the output gap varies roughly between 2 and -2 percent from 2005 to the end of 2007. The change in the productivity gap varies roughly between 0.5 and -2 percent over the same period. The change in the output gap bottoms out at -8.4 percent in 2009 Q1, and does not turn positive again until 2010 Q1. The change in the productivity gap peaks at 4.1 percent in 2019 Q4. From the end of 2010 to the end of the decade, there is comovement between the variables and they collectively vary between -2 to 3.5 percent, approximately.
