Do real stakes/incentives matter in experiments? Recent studies say they don’t. My new paper shows that these studies’ results — and those of most hypothetical bias experiments — are uninformative when we care about experimental treatment effects. 1/x

@jayvanbavel But can the exact output of gpts always be reproduced?

The lawsuit against Data Colada includes interesting evidence. This table summarizes it.

A new blog on AccountingExperiments called: "The Fall of Constantinople for Amazon's Mechanical Turks?" by Christian Peters (@cphpeters) Read it now: https://t.co/VbauSdy7xF #research #mturk #experiments #accotwitter

@Heraa_nera @RyanGuggenmos @aaahq Interesting study showing MTurk (specifically) may now really be beyond saving... https://t.co/1eM9BLvJQ0

[Victor van Pelt @victorvanpelt]

Great overview slide of Mturk-oriented research (in accounting) by @RyanGuggenmos at the @aaahq MAS Midyear Meeting. Thanks for sharing!

[Victor van Pelt @victorvanpelt]

@mdmahlendorf This is great! Congrats!

@Musa_alGharbi Same experience for a year or so. The quality has decreased steadily over the past years for different kinds of studies. The pool is now unusable for me.

350+ coauthors study reproducibility in economics https://t.co/AWfXh1wHbj

We always run fun meme-creation mini-assignments in accounting courses. This one really cracked me up this time 🤣😂. All the credit goes to the student.

[John V. Kane @UptonOrwell]

Ever need to make bar graphs of means in @Stata? Ever wish you could add confidence intervals?

If so, I made a new guide in the #StataGallery on @Medium on how to do it using -cibar- and/or -coefplot-. Lots of examples, tricks & all of the code. 😎

New publication on the relation between cognitive abilities and risk preference:

This relation critically depends on the risk elicitation method and the choice architecture within behavioral measures.

With J. Rieskamp & R. Hertwig.

It may not be a surprise, but a series of experiments show that deadlines are very effective in motivating action, and also shed light on why: we have limited memory & attention, so deadlines focus us on tasks before we forget about them. Shorter deadlines are more effective.

[Jan Feld @EconFeld]

Is better writing rewarded in peer review?

Our newly published suggests the answer is “Yes”!

The AI revolution’s first year: has anything changed? https://t.co/vaofxTyFdf

[Victor van Pelt @victorvanpelt]

Pleased that @WHU_edu just featured a short piece on my recent study in @CAR_RCC_Journal. It reveals that it is more challenging for people to relinquish control than take it. Big thank you to two anonymous reviewers and the Editor, Khim Kelly. https://t.co/PfXk5Lzqz8

[Victor van Pelt @victorvanpelt]

There is a lot that accounting experiments can do in that regard. Even the optimists: https://t.co/N5xeY3SH0C

Pre-registration, transparency, and large samples boost behavioral studies’ replication rate from 50% to nearly 90% https://t.co/EBMeHWP4u4

[Victor van Pelt @victorvanpelt]

@econ_martens gave a great workshop @WHU_edu last Friday about his working paper "Do Firms Listen to Social Media Analysts? Evidence from Seeking Alpha." We gave him some weaponry to fight off our tough questions. It shoots foam bullets. So, no one got hurt, just their dignity.

[Victor van Pelt @victorvanpelt]

@gr0ssmann is this some version of independence of irrelevant alternatives? Decoy?

[Victor van Pelt @victorvanpelt]

@gr0ssmann Sounds interesting :-). Is there more info anywhere?
