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

⛽ 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.

🚨 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?

The end of online experiments?

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:

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.

Look at this cute little angle

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).

CALL FOR PAPERS 📈📉 The Behavioral IO and Marketing Symposium (biomsymposium.org) will be held on 5/15-16 at UMichigan. This is an opportunity for IO and Quantitative Marketing researchers working on behavioral economics topics to interact. Submit to [email protected] by *December 15, 2024*.

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.

IDF special forces and Shin Beit release one Israeli hostage held in Gaza.

This is real. It is a terrible day for the Cornell community.

What? Anti-Israeli sentiment leads to antisemitic violence? I’m shocked. Shocked! Who would’ve thought?

www.youtube.com/watch?v=B8YY... Those who know the region and understand what's happening also know who's responsible for the suffering in Gaza. I recommend taking a few minutes to listen to what Mosab Hassan Yousef has to say.

Please stop equating Gazans and Hamas, especially if you don't know how Hamas came to control Gaza. Please stop referring to Hamas as a Palestinian freedom movement, especially if you don't know how Hamas came to control Gaza.

If you want to free Gaza you need to free it from Hamas. Reminder (or news): Israel left Gaza in 2005. Hamas took over in 2006 and since then did everything in its power to harm Israelis and Gazans alike. It is not fighting for freedom. It’s fighting only for the annihilation of Israel.

Bring them back

Each empty seat is a hostage. Each one pain, and fear, and praying for their safety, and the resolve to bring them back. Kids, babies, elders, teenagers, friends, cousins, brothers, sisters, nieces, nephews, grandmas, grandpas, parents. The pain is beyond comprehension. A dark hole in the soul.

Happy 3rd birthday to the goodest Bo

Wouldn’t matter for those who blame Israel for everything anyway, and doesn’t reduce the suffering of those affected, but good to get corroboration from the National Security Council.

Listening to Rona Kenan while reading the news: “Give me a reason to believe That the sorrow has an end.” Amen 🙏🏼 spotify.link/tjgl0h1HYDb

I posted yesterday a call to reach out to friends who are suffering due to the situation in Israel and Gaza. Relatively many people liked that message. Hypothesis: Had I not mentioned Palestinian suffering fewer would have. Why? Because they’d assume acknowledging Jewish suffer is taking a side :(

199 hostages! 199 kidnapped! And that’s not even the final number. stories.bringthemhomenow.net

PSA: many of your Israeli, Palestinian, and Jewish friends and colleagues are experiencing trauma and grief right now. Reach out to show you care about them. One human being to another. Politics aside. I’m not okay but I gain much strength and comfort from all of you who did so. Thank you.

Was video chatting with my mom and an ambulance drove outside our window. The look on her face until I reassured her it’s coming from here and not a siren :(

This is like someone saying “my grandmother just died. I’m grieving.” To which another answers “How dare you only think of your grandma right now, you monster, other people died today too.”

Ending the occupation and “freeing Palestine” requires the removal of Hamas. There can be no safety to Israelis, and definitely no peace, otherwise. Do you want to free Palestine? Hamas is your enemy, not Israel.
