AI Summary. Euro-area income per person falls behind the US when measured in constant 2021 prices but gains on the US when measured using each year's prices, suggesting Europe is holding its own in applying technology. The author argues Europe's real risk is being cut off from strategically important technologies.

In 2021 prices, per capita GDP in the Euro area is falling relative to that of the US, but the opposite is true if one takes into account the benefits to Europe from falling tech prices. “The big benefits of IT come from applying it, [not] creating it.”

Does Europe's income gap with the US depend on price measurement?

Core argument: Euro-area GDP per capita relative to the US declines over the past 25 years when measured in constant 2021 prices, as the World Bank does, but rises when measured at each year's prices (PPP).

Let’s start by looking at GDP per capita in Europe (actually the euro area) as a percentage of GDP per capita in the US. If we do this using constant prices — the World Bank uses 2021 prices — we get the line in Chart 1 labeled “2021 prices.” This line shows Europe falling behind over the past 25 years. If, however, we simply use prices in each given year, we get the line labeled “PPP,” which shows Europe gaining on the US. We get a similar picture if we look at GDP per worker-hour, where the black line is calculated using 2021 prices and the blue line is calculated using PPP. IT progress is passed on to all consumers via lower prices. The big benefits of IT come from applying it, rather than creating it. And as I’ve tried to show, the data show Europe holding its own in the relative value of the goods it produces, indicating that European economies are doing fine when it comes to applying technological advances. What should worry Europe, instead, are the geopolitical implications of US/Chinese leadership in advanced technology. The risk of being cut off from strategically important technologies, once minimal, is now very real. And that risk, rather than misleading numbers about trends in real GDP per worker hour, is what should concern European policymakers.

Takeaways by Macro Roundup® AI

  1. Euro-area GDP per capita relative to the US declines over the past 25 years when measured in constant 2021 prices, as the World Bank does, but rises when measured at each year's prices (PPP).
  2. The same divergence appears in GDP per worker-hour, where the constant-2021-price series and the PPP series point in opposite directions for Europe relative to the US.
  3. The author argues that Europe is holding its own in the relative value of the goods it produces and in applying technological advances, and that the real concern is the risk of being cut off from strategically important technologies amid US and Chinese leadership.

  • Europe v America: Who’s Really Winning? — Real GDP data show the US economy growing substantially faster than the European Union's, yet on a purchasing-power basis adjusting for price levels, the EU economy remains only slightly smaller than the US, as it was earlier. The author argues US dominance in information technology, where productivity growth is rapid and passed on as lower prices, reconciles the two measures.
  • Europe’s Tech Lag: Does It Matter? — If technology producers face competition, faster measured productivity growth in a tech-specialized country is passed to consumers in both countries through lower prices rather than higher relative living standards. Real GDP per worker over 1998-2024 diverged more between California and the rest of the US than between the US and Europe, largely reflecting industry composition.
  • From IT to AI: What Explains US Productivity Outperformance? — Larger information-technology quality adjustments and hours-worked measurement distortions explain about 30% of the average annual US-Euro area total factor productivity growth gap since 1995, leaving an adjusted gap near 0.25pp. The authors estimate greater US intangible investment spillovers contribute about 0.1pp, more efficient resource allocation about 0.1pp, and better management and larger firms about 0.05pp.
