AEA Data Editor @aeadata.bsky.social · 24/07/2026Recent case, re-run of the authors' code failed on a first-stage regression, blocked code from completing.

AEA Data Editor @aeadata.bsky.social · 14/07/2026From an anonymous replication package: the underlying ACS housing-unit microdata (~14 GB across 2006–2019) are **not** redistributed here because of their size. I understand that even back in 2006, 1.44MB floppy disks were going out of style... We draw the line at about 2TB, we have solutions! 080
AEA Data Editor @aeadata.bsky.social · 26/06/2026I just wanted to remind folks: Excel!

AEA Data Editor @aeadata.bsky.social · 25/06/2025I would like to re-emphasize that when data are "publicly available" (as authors frequently mention), the LICENSE matters. Most AEA replication packages are fully or partially under a #CC-BY license. You have ONE (only ONE) obligation, but you MUST fulfill that one obligation: CITE THE DATA! 2245
AEA Data Editor @aeadata.bsky.social · 25/06/2025#sole2025 coming up! I'll be there, hanging around the post-lunch Poster session (P01/2 Metropolitan East) on Friday, if you have questions! (My name tag will give me away). Or buttonhole me at the Cocktail reception on Saturday. 110
AEA Data Editor @aeadata.bsky.social · 29/05/2025It is always a pleasure, but also causes some trepidation 😰, when a bunch of motivated junior (and senior!) researchers get together at @i4replication.bsky.social replication games, and I get to observe how others work with the replication packages that we helped prepare! #Montreal 1346

AEA Data Editor @aeadata.bsky.social · 17/02/2025Short note on provision of "raw" data in replication packages. "Raw" are data files exactly as downloaded from original source. Not renamed, not converted, not made prettier. All that is important, and is the next step, for which you provide code (or instructions). But "raw" is as "raw as it gets". 26519

AEA Data Editor @aeadata.bsky.social · 22/10/2024We try to provide authors with much information on how best to prepare the packages. But ultimately, the key first step in preparing a package is... to run the code at least once again, top to bottom. This will regularly detect issues and differences.
