measuring productivity

There was a recent Wall Street Journal (which I don’t subscribe to) article arguing that productivity has not really slowed down, that we are just not measuring it correctly. This Brookings paper argues against that idea.

After 2004, measured growth in labor productivity and total-factor productivity (TFP) slowed. We find little evidence that the slowdown arises from growing mismeasurement of the gains from innovation in IT-related goods and services. First, mismeasurement of IT hardware is significant prior to the slowdown. Because the domestic production of these products has fallen, the quantitative effect on productivity was larger in the 1995-2004 period than since, despite mismeasurement worsening for some types of IT—so our adjustments make the slowdown in labor productivity worse. The effect on TFP is more muted. Second, many of the tremendous consumer benefits from smartphones, Google searches, and Facebook are, conceptually, non-market: Consumers are more productive in using their nonmarket time to produce services they value. These benefits do not mean that market-sector production functions are shifting out more rapidly than measured, even if consumer welfare is rising. Moreover, gains in non-market production appear too small to compensate for the loss in overall wellbeing from slower market-sector productivity growth. Third, other measurement issues we can quantify (such as increasing globalization and fracking) are also quantitatively small relative to the slowdown. Finally, we suggest high-priority areas for future research.

“Non-market” eh? I think some of the twisted sentences in there are arguing that we may have reached a point in richer countries where we value things that are not measured in money. Bradford Delong kind of agrees with me, saying:

Isn’t “measuring consumer welfare” the point? We (a) arrange atoms (b) in forms we find pleasing and convenient, and then use them in combination with (c) information and (d) communication to accomplish our purposes. That our measures of economic growth are overwhelmingly “market” measures that capture the value of (a), much of the value of (b), and little of the value of (c) and (d) is an indictment of those measures, and not an excuse for laziness by shrugging them off as “non-market” and claiming that measuring the shifting-out of market-sector production functions is our proper business.

Finally, I got on this growth and productivity kick after reading this article in FiveThirtyEight, which links to a lot of the above sources.

None of this economic commentary ever talks about links to the physical world or ecosystem services. I will puzzle that out one day.
