Diverging TFP performance 1995-2007
• TOP DOWN PERSPECTIVE
• U.S. Exceptional 1995-2003
• Technology slowed
• Not mismeasurement
• France/Germany Structural
rigidities
• Italy, Spain Capital flows
fueled misallocation
• U.K. Mismeasurement post-
2008?

Accounting for U.S. growth: Varying rates of normal

Slow U.S. TFP growth since 2003

Rise and fall of TFP growth in IT-intensive market services

Post-2004 slowdown
not in “bubble

construction,
mining/ag…)

“The things at which Google and its peers excel, from Internet search to mobile
software, are changing how we work, play and communicate, yet have had little
discernible macroeconomic impact. …Transformative innovation really is happening
on the Internet. It’s just not happening elsewhere.”
Greg Ip, Wall Street Journal, August 12, 2015
Productivity paradox 2.0
-
“Today’s information age is full of sound and fury signifying little.”
Martin Wolf, Financial Times, Oct 2, 2012

-
A productivity problem or measurement problem?
• Goldman Sachs, Google, and others point to specialized equipment, software,
and free digital goods
– Quality-adjustment is hard—maybe national accounts are behind curve?
– Facebook, Google, etc. are free (to users)
-
Growing mismeasurement doesn’t explain all

-
Why did continental Europe diverge?
-
No. Ideas flow across borders but have to be implemented locally
Timing of “intangible investments” (e.g., reorganizations associated with IT) can differ
Theory: Basu, Fernald, Oulton, Srinivasan (2003)
Evidence: Corrado, Haskel, Jona-Lasinio, Iommi (2012)
Should the same IT story apply equally everywhere?
20
-
“Reallocations” and reorganizations that didn’t happen because of
regulatory barriers E.g., van Reenen et al (2010), Bourlès, Cette, Lopez, Mairesse, and Nicoletti (2013), Cette,
Lopez, and Mairess (2013)…
Institutions hold back technology in continental Europe
21
-
Reis (2013), Gopinath et al (2015), model it as effect of capital inflows
interacting with financial frictions
Underdeveloped financial sector channels funds to less productive projects
Increasing misallocation
Macro implication: Exogenous decline in real interest rates leads to low
productivity growth
Channel: Low-productivity firms get financed. Average productivity of firms falls.
Why did TFP in peripheral Europe collapse relative to frontier?

=>VAR with labor productivity (or TFP growth) and real interest rates
Choleski identification with real interest rate last

-
Real interest rate “shock” raises labor productivity (Euro area)
24
-
25
Historical decomposition: “Explains” some low periphery LP growth
-
What about the United Kingdom?
26
-
An incredible coincidence?
27
-
Coincidence…until the Great Recession
28
-
TFP growth in many advanced economies slowed prior to Global
Financial Crisis
Story involves technology, structural rigidities, and capital flows
Slowing technology growth at the frontier, reallocations that didn’t happen because of
rigidities…and misallocation that did happen
As OECD (Future of Productivity) emphasizes, “diffusion” that isn’t happening is key
U.K. remains a puzzle: Could import/export deflators be misleading?

Typically slower productivity growth after 1995…
and even slower 2004-07
