I just wanted to remind folks: Excel! "In updating the replication package so that inputs for Figure 1 are produced by code... hard-coded input cell in the Excel workbook ... outdated reference" Luckily, caught, and change was minor. Please use code to produce tables, figures!

Also just a few spots available in VANCOUVER, with registration closing May 12, for #CEA2026 .

Last chance to sign up if you haven't already, we're kicking this off next Monday May 11. Venez tous et en grand nombre (unless you're a ⚡fan, I guess... )

I am firming up spring and summer conference planning, and if you are too, here are a few where I will be leading or contributing to training on reproducibility (for journals and for your own research) 🧵

🧵For authors preparing the replication packages that accompany their 2026 AEA Papers and Proceedings publication www.aeaweb.org/journals/pandp: Here are some notes on preparing your replication package (1/8)

For those who attended the Jan 3 and 4 sessions at #assa2026 and want a copy of the slides, or those who couldn't make it: Jan 3: Reproducibility from Day 1 larsvilhuber.github.io/day1-tutorial/

🪅DHS (not that one) Program website active again, and accepting requests for data access dhsprogram.com/Who-we-are/N... (via @ipums.bsky.social )

I 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!

#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.

It 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

Summer is approaching, and so are various conferences. As so often, I target being available at various conferences, including presenting and answering questions. Here is a list of places and times in the next two months.

Users of the Demographic and Health Surveys, please take the United Nations Statistics Division DHS impact survey (form.jotform.com/250913880478...) regarding recent cuts. Replies inform future planning and advocacy. All responses are confidential and presented only in aggregate.

Worthwhile to attend: rdapassociation.org/event-6142604

My apologies for not posting this earlier (there's other stuff happening), but for those wrapping up their AEA Papers and Proceedings replication packages, here is some guidance aeadataeditor.github.io/aea-de-guida...

Hopefully this is a useful tool: findlostdata.org

Short 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".

Some excellent guidance from MIT on step by step data preservation of secondary data: libraries.mit.edu/data-managem... (via Wendy Kozlowski orcid.org/0000-0001-65...)

Possible additional info for those seeking data: (no endorsement, just info) www.datarescueproject.org/current-effo...

We are seeing some impact on reproducibility efforts with the transition to the new US administration. For now, I suggest that you make backups of any data that required you to actively interact with the Federal government, as there may be a delay in response times.... #openscience

The AEA ad hoc Committee on the use of Social Media in Economics has released a report with details on their process, findings, and recommendations. We encourage you to read the report: www.aeaweb.org/about-aea/co...

I sometimes see researchers doing copy-pasting between output from Stata/R/MATLAB ➡️Excel, to create tables. This is a lot of work, source of many copy-paste errors & a bad 👿idea. I describe 1 way to avoid this, even when you don't want to invest in a new and better tool. Think "halfway house"...

Up on Saturday morning at #ASSA2025 : Day 2 of reproducibility tutorial by data editors. Any input to the topic? Answer our survey: cornell.yul1.qualtrics.com/jfe/form/SV_...

Last chance! #ASSA2025 to fill out the survey! See you all in an hour at the tutorial on reproducibility DAY 1!

#ASSA2025 If you want to influence (a bit) on what we present in our Tutorial on Reproducibility (DAY 1) FRIDAY 8:00 AM , do fill out this survey: cornell.yul1.qualtrics.com/jfe/form/SV_... . Results: live tomorrow morning!

Reposting this b/c of course it's #ASSA2025 !

As folks are planning for the #ASSA2024 meetings, if you have questions or want to learn about the best way to conduct reproducible research and (later) prepare replication packages, come to our two sessions, joint w/ Marie Connolly @CanJEcon , co-sponsored w/ @ecmaeditors.bsky.social

An oldy but goldy: friends don't let friends (with Windows computers) use "\". See aeadataeditor.github.io/posts/2021-0...

Happening today #2024appam @appam.bsky.social room National Harbor 1 at 1:00pm

Thx to GtownU & Amy O'Hara, we have a space for Friday Nov 22: 125 E Street NW, 9th floor Convening Space Meet w/ me @larsvil.bsky.social Joan Llull ECTA & Farasat Bokhari WEAI to learn&ask about best practices in preparing replication packages for publications in Economics #2024APPAM #2024SEA

#AMA #dataeditortips If you missed us so far, @larsvil.bsky.social will be at #2024APPAM on Saturday Nov 23 for a Q&A session. Happy to answer all sorts of questions, just drop in, ask, listen. #WashingtonDC

We (@larsvil.bsky.social Joan Llull ECTA, Farasat Bokhari EI), are preparing a small 1 hour workshop (short presentation + Q&A/AMA) in Washington DC on Nov 22. Day before SEA, middle day of APPAM, available to all economists in DC area. Can I get 👍on how many #econsky folks would show up?

We 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. Two small "case studies". 1/3

Highlighting what other academic societies do for reproducibility: see what the premier statistical society (in 🌎) does here: doi.org/10.1080/0162...

Here's a soapbox post #dataeditortips : Copy code once, fine, don’t do it again. Copy 2x, stop, and create a function. Copy 3x: don’t even go there!😠 We often see researchers doing lots of copies. Not a great practice. FWIW, some tips: aeadataeditor.github.io/posts/2024-0...

@cornell students only: We are hiring again for the Fall Semester, see www.ilr.cornell.edu/labor-dynami.... Deadline for applications is August 20, in-person training will be August 24.

Coming up! 👇 #reproducibility #econsky #seattle #weai

If you missed us so far, @larsvil.bsky.social will be at #weai2024 #weai99 in #seattle on Mon Jul 1, 2024 | 8:15 AM  -  10:00 AM. Happy to answer questions afterwards as well. weai.org/conferences/... #dataeditortips

Forgot to mention - not an #AMA but a tutorial/workshop on reproducibility (from day 1, and overall) at CEA annual conference #CEA2024 #toronto - come by Saturday morning June 1 8:30 AM (with Marie Connolly CJE #dataeditor )

We strongly encourage you to always be very clear about how, where, and when you collect your data. Data provenance is important, even if the actual data collection is not itself reproducible. #dataeditortips www.wired.com/video/watch/...

On the use and redistribution of data - or why researchers get confused... (hint: it's not JUST their fault...) aeadataeditor.github.io/posts/2024-0... #dataeditortips #openscience

#DataEditorTip In the AMA's, we talked about many things. No transcript, but here's a raw dump of the various websites that were used. To start, of course: AEA Data and Code Availability Policy: www.aeaweb.org/journals/dat..., and if revising a package, www.aeaweb.org/journals/dat...

Despite 🌧️🌨️💨in Boston, AMA will happen! 💪☔See any interested folks either at 2PM at BU, 4PM at MIT!

❗️👇 AMA alert - I will be in Cambridge and Boston April 4-6. Two #AMA (ask me anything...) coming up #econsky

❗️👇 AMA + tutorial ❗️March 23, 2024 MEA meetings in Chicago, IL mea.sites.grinnell.edu Marie Connolly (Data Editor, 🇨🇦) Sofia Encarnación (AEA, pre-doc) & I present on "Don't Worry, Be (Reproducibly) Happy! Reproducibility from Day 1 and Day X" virtual.oxfordabstracts.com#/event/4777/... #MEA2024

❗️👇 AMA alert - I will be at the BITSS meeting. If you have questions to ask of the Data Editor, come and find me at the meeting in a break! Send me an email - we don't check DMs on this platform very frequently. www.bitss.org/event-types/...

As Data Editors, we cannot always peek behind the veil of what researchers do before submitting the final replication package. We certainly hear both positive and negative feedback, and are acutely aware that reproducibility is not an easy task. Here I convey a few of the more positive feedback: 1/n

It was fun visiting Joan Llull (Data Editor for ECTA) in Barcelona earlier this week! Data Editors @aeadata.bsky.social working late into the night! twitter.com/JoanLlull_ec...

We are seeking to hire a pre-doc as @larsvil.bsky.social assistant starting July 1, 2024. Application at cornell.wd1.myworkdayjobs.com/en-US/Cornel... Also listed at predoc.org/opportunities

We are doing everything to preserve for the long term your digital artifacts (data, code) to supplement the papers you publish in the @aeajournals . www.youtube.com/watch?v=fzI9...

Continuing with the "ask me anything" (related to reproducibility, transparency, data access, etc.), I'll be at UMichigan on Monday, January 29, 2024 at 5-6.00pm in the Econ Department. Bring questions, the department is providing ☕🫖🍪. If you did not get the invite, reach out to the Econ DGS.
