- 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!

- 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....
- Reposted by avnershlain🚨 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?
- New working paper, "Goals, Expectations, and Performance," from @avnershlain.bsky.social (Chicago Booth) and Alexandra Steiny Wellsjo. ow.ly/pYSf50UUm9X
- What goals do people choose? Participants typically set goals they expect to hit ~78% of the time. Few choose goals they think are less than 50% likely to be achieved.
- Do goals shape expectations? We find that expectations drive goal-setting. Manipulating expectations changes goals, but tweaking goal difficulty doesn't significantly affect expectations.

View full threadIn summary: - Higher expectations increase goals (A) and performance (C). - Goals reflect expectations but do not affect them (!B). - Having a goal improves performance (D) but the level does not matter (!E).

- The end of online experiments?
- 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
- @aleximas.bsky.social referred me to Nightshade (nightshade.cs.uchicago.edu/whatis.html). Basically, if we find a good-for-its-time way to hide the instructions from AI, such as Nightshade, then can proceed.
- As @joshtdean.bsky.social figured out — Nighshade is of no help here.
- 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:
- My friend’s mom always puts lottery scratch cards in their family xmas stockings. One year his dad found some prank cards. You scratch and for a few short minutes think you won $10K. People got very excited and then very upset. And they were more upset than happy! Losses loom larger than gains.
- This is an anecdote of course, we actually have a lot of evidence consistent with PT and others. But the point is that these theories are good descriptive theories because they capture and distill something we all know is true. And same goes for complexity - we know we get stumped. We need both.
