When Israeli supermarkets were forced to adjust prices under a reform, firms learned new strategies and improved—but still priced inefficiently. Research by Avner Strulov-Shlain 🎗️ shows how firms learn from experience. https://ow.ly/IPYm50XjOT1

Firms Have Partial Knowledge: Evidence from a Reform | Becker Friedman Institute

Economists typically assume that firms are sophisticated and make optimal decisions. Yet, in practice, firms often make mistakes. This study asks why: Do firms know the right action but fail to implement, or do they lack knowledge of the optimal action? To explore this question, Strulov-Shlain examines a 2014 Israeli reform that banned prices ending Read more...

⛽ For an academic study, we (@akraft.bsky.social and I) wish to interview US Gas Station owners to learn more about their business practices. Please share or send anyone you know to Andreas or me. Thanks!

We'll be back at Jimmy's on Tuesday 3/25 and EVERY LAST TUESDAY OF THE MONTH! Come once and you'll come again. @abionsky.bsky.social @williamhjhubbard.bsky.social @avnershlain.bsky.social @dfordon.bsky.social @elderserpiente.bsky.social

I am very happy to share that I am being promoted to Associate Professor of Marketing at The University of Chicago Booth School of Business. I am incredibly grateful for my family, and for my friends, coauthors, mentors, and colleagues who made it all possible. Excited for the years ahead!

No wonder retailers ignore left digit bias. Indoctrination against it starts in school! Cc: @justinsydnor.bsky.social @nicolacetera.bsky.social

An instant hit paper claimed that "Decisions under Risk Are Decisions under Complexity". Re-analysis shows no evidence in support of the claim, and perhaps even the opposite: - The experimental design causes noise to generate the results. - For non-confused participants risk != complexity.

A new working paper with Daniel Banki, @urisohn.bsky.social and Robert Walatka, just submitted to SSRN. The paper is comment on Ryan Oprea's recent AER paper. The paper is processing, but you, my friends, get early entry. papers.ssrn.com/sol3/papers....

🚨 Oprea (2024 AER) argued that prospect theory choice anomalies were not due to risk, but due to complexity-driven mistakes. But this new analysis convinces me that Oprea (2024) is substantially wrong. In my opinion, the paper should be retracted.

In this new working paper we use a real-effort experiment to study the relationship between self-set goals and expectations, and how they affect performance. Do goals affect or reflect expectations? Do goals affect performance, conditional on expectations?

Just used Gemini Live to participate in a beh. experiment without even reading the instructions or speaking the language. LLMs acting as participants on platforms like Prolific could pollute data meant to study humans. With OpenAI’s operator model, this issue is growing. 🎥👇 youtu.be/NujyGZSA7Hg

in Hebrew we say you are in a state of “emotions storm” or even just “stormed” when having lots of emotions. I am stormed with hope, relief, anxiety, dread, regret, gratitude, anger (to name a few). Welcome back Romi, Emily, and Doron ❤️‍🩹 twitter.com/haaretznewsv...

A road-trip inspired research idea, free disposal: Estimate the effect of speed limits on accidents by using interstate roads and difference in states limits. E.g, the I-55 is up to 75mph in AK, 70 in MO and 65 crossing to IL. With good enough data can be quite credible IMO.

Hotels, venues must disclose “junk fees” to consumers in initial search results Good legislation. The only downside I can think of for consumers is that you can no longer tell yourself (or your spouse) that “it is only $200 a night” when in reality it is $350.

#econsky Economists: If you ever wondered what is “quantitative marketing” about, @avigoldfarb.bsky.social’s syllabus is a great place to fill in the gap. If you never wondered about it - you can learn about it nonetheless.

#econsky I agree that PT is descriptive, and complexity is important in driving choice patterns. But I think that the success of PT and behavioral econ is due to more than just explanatory power. These theories resonate. They are not surprising. The intuition brought the theory and evidence. Story:

Alex Imas@aleximas.bsky.social · 2y ago

Phenomenal paper, one of my absolute favs! 2 points: 1) prospect theory is a *descriptive* model of choice. Choice still there, new work is getting us closer to understanding mechanism. 2) not clear whether choices are response to risk, and people apply same heuristic to similar non-risk contexts

We're looking to hire a Postdoctoral Principal Researcher/Chief Scientist to work with @chicagobooth.bsky.social faculty in the Roman Family Center for Decision Research! Please pass along!

I’m curious — how many of your Spotify end of the year top5 artists would you get right? If you haven’t checked your summary yet even better - guess first and then check and please let us know!

Folks! Our excellent BFI institute at UChicago is on here, give them a follow. They do an excellent podcast (the PIE) and host great conferences/workshops with open call-for-papers.

I suggested that the average American might not be angry about asking federal workers to work from the office. I got dog piled. No one looking for an actual discussion. Just name calling. Over 100 messages like this. After a week long experiment, I don't think I can stay here any longer.

1983 Jerry Seinfeld tells Judd Apatow his vehicle for more exposure is doing quality work. He also says that doing quality work is for his own sake. This is the correct advice for PhD students (and beyond).

I didn't log in for a year or so, and suddenly things are happening here! So, new folks - below is a short intro to some of my papers. Since I wrote this thread some of these have been accepted for revisions or publication, and one may be submitted before I become a grandparent. Hard to tell.
