Today the BLS reported productivity -- that is, real output per hour worked -- for Q4.
It continues to grow, as shown in Figure 6 below (these are figures from my paper "What Caused the Recession of 2008? Hints from Labor Productivity"). Interestingly, the more severe recession of 1981-82 had productivity falling, as did the Great Depression (not shown).
The conventional wisdom ignores the comparison with previous recessions, and says that productivity falls merely because labor hours are falling. That is incorrect. I prove this by calculating a "productivity residual" -- the amount of the productivity growth that cannot be explained by the fact that labor fell. The productivity residual has been rising in this recession -- much like it does during non-recession times.
Productivity residuals are shown in Figures 5 and 7 (productivity residuals are measured in the quantity dimension so that they can be compared with changes in the amount of labor). The 1981-82 recession had the productivity residual falling (that is, given that jobs were lost in that recession, productivity should have risen but in fact it fell -- so the productivity residual must be falling). So did the Great Depression.
