Is Europe falling behind the US on productivity? The Krugman vs Aghion–Bergeaud–Garicano debate hinges on one choice: current vs constant PPPs. A new note maps the gap behind it — all 27 EU states, two data sources — and what it does and doesn't settle. 🧵

Some recent new discussions about total factor productivity (TFP) numbers in @PennWorldTable, with the notably reductive post by @Noahpinion as a low point: nitter.gq/Noahpinion/status/2021… (1/)

📊 Data update: The @PennWorldTable is an extensive database that helps us understand long-run, global trends in economic growth, working hours, productivity, and living standards.
We’ve updated 17 of our charts using the latest release.
This data gives us a clearer picture of how countries compare today, and helps us understand how technology, innovation, and better use of resources have shaped economies and living standards over the last 70+ years.
The Penn World Table is maintained by researchers at the University of Groningen and the University of California, Davis. This year they celebrate their 50th anniversary!
This update was led by @parriagadap and @BerthaRohenkohl.
ALT A line chart showing productivity, defined as gross domestic product (GDP) per hour of work, for a selection of 10 countries from 1950 to 2023. The data is adjusted for inflation and differences in living costs between countries. At the top of the chart is Denmark, with a productivity of 88.7 $ per hour. At the bottom is Ethiopia, at 4.5 $ per hour. The data source is the Penn World Table (2025). The chart is licensed CC BY to Our World in Data.
On October 7, 8 and 9, Robert Feenstra, Robert Inklaar and Chad Jones will give lectures in the IEA Lecture Series on the 50th Anniversary of PWT. Robert Inklaar's will include a preview of PWT 11 numbers. For more info and registration, see: iea-world.org/pwt/
The recordings of the lectures have been posted here: iea-world.org/, under Latest Videos
Version 11.0 of the Penn World Table has just been released. You can download the data and documentation here: rug.nl/ggdc/productivity/pwt…. This new version covers 185 countries and the period 1950-2023
We can continue to track international income inequality with these new data and at tomorrow's IEA lecture (iea-world.org/pwt/), Robert Inklaar will discuss more results from PWT 11.0
This new version includes new data from ICP (worldbank.org/en/programs/ic…), through 2021 and new National Accounts data, through 2023. Most notable change in terms of data construction is that our (default) data for China are the official series
It is with deep sadness that we announce the passing of Alan Heston, Professor Emeritus of Economics at the University of Pennsylvania and one of the original architects of the Penn World Table. We honour his memory here: rug.nl/ggdc/blog/alan-heston…
Thanks for the shoutout @ATabarrok, couldn't agree more! mercatus.org/marginal-revolu….
From the GGDC, new Productivity Level Database with data for 84 countries, 12 sectors and 3 years (2005, 2011 and 2017). Plus new findings, see 👇
What sectors make lower-income countries so unproductive? Answering this question needs good new data and a fresh view on which sectors are tradable. A 🧵 thread on a new database and paper (rug.nl/ggdc/html_publication…) (1/8)
Our colleagues at the University of Queensland have released a new version of their database on comparative income levels: uqicd.economics.uq.edu.au/. Compared to PWT, this database has much information on within-country inequality and uses another approach to income comparisons.
We have released a minor update of the Penn World Table, version 10.01, see rug.nl/ggdc/productivity/pwt…. This update changes part of the calculation of investment prices and most notably impact capital growth.
Details of this change can be found here: dataverse.nl/api/access/data…, which also includes a discussion of the quantitative impact on the most-affected variables.

A recent post argues that the Maddison data on income levels in Haiti and Dominican Republic are wrong. That claim does not hold up well, see rug.nl/ggdc/blog/maddison-pr…
More so than usual, we received input from users puzzled by some of the outcomes in PWT 10.0. In many cases, we can provide satisfactory answers, but in several we had to reconsider our approach. We have thus released three updates already, see ggdc.net/pwt.
We realise that with every modification we make, there will be a need for people to download the data anew and there may be discrepancies in the versions different people use, even though these are all referred as PWT 10.0.
We hope this also demonstrates to you our commitment to providing a database that is as reliable, a development team that is responsive to your input and a source that is transparent about the choices made. As always, we welcome your reactions here or via [email protected].
