One of the best minimum wage papers to date, leveraging IRS tax data on businesses, matched to individual survey data, and a clean difference-in-difference design using 19 sizable increases in the 2010-2019 period. Sheds light on jobs, revenue, reallocation effects.

Okay. One more comment. Earlier I distinguished A/B testing from price discrimination. The A/B testing would be to learn about your demand curve for the market. There is another possibility for prices hopping around: strategic randomization. The intuition is this: if you
Let me say a bit more about different shoppers seeing different prices on Instacart for the same products. The framing treats this as alarming evidence that "the notion of a single price is breaking down." The article involves at least three distinct concepts that economists

To be clear, they don’t find evidence of price discrimination (as much as I wish they would). Companies are randomizing prices. That’s the story?

If you're going to plot means and CIs to show your results, they should be 83% CIs (not 95% CIs). Why? Because then when people look at whether they overlap, the implicit statistical test has the correct size.

I decided to let AI help edit a brief comment for me to post with this link on Facebook.

It is so obvious, and also makes it hard to give credit for good ideas (e.g., students in course discussion boards). I think a lot of people use AI to edit, and it takes their ideas and makes it look like AI.

If only they were robotic! Instead, chatbots have developed a distinctive — and grating — voice.

This is a very cool paper. It first shows that first-gen college students don't realize a lot of unwritten rules that lead to success (the value of internships, student clubs, letters from professors). But giving them access to an LLM for guidance significantly closes the gap.
My student Michael Cuna is on the econ job market this year. He has an excellent paper showing the impact of the hidden curriculum on educational outcomes, particularly in the case of first-gen students. The paper also demonstrates the potential for AI tools to close these gaps.

True fact: The optimal amount of bad things is almost never zero! (This unpopular opinion is a fun conversation starter at parties.)
One of my core lessons in my business ethics class to MBAs is that the socially optimal level of ground insect matter in coffee pods is not 0%.

Very excited that my former advisee @melissa_newham has a paper in AEJ Micro showing that common ownership reduces competition in pharmaceuticals. When generic firms share investors with brand-name producers, they are significantly less likely to enter after patent expiry.

Once during a job interview, the interviewer said the best part of the job was that he could go home early and watch Oprah. I didn’t take the job. Turns out that my reaction is common—people aiming for top positions read easy questions as a sign of low competence and poor fit.
🚨1/N Really excited to announce a new working paper, “Interviews” 🚨 We demonstrate that interviews allow workers to screen firms and preview whether the job is a good match for them—using ~500k Glassdoor reports + a randomized field experiment. 🧵

Being doxxed as a member of the Ku Klux Klan had "no statistically significant effect on any outcomes of interest". Can't wait to read this JMP

[1/3] Men's testosterone levels did not plummet over the past decade like many wellness podcasts would have you believe... we just switched the measurement assay from immunoassay to mass spectrometry When we switched assays, we observed a ~100% increase in self-reported healthy

I think this is kind of neat and I don't think anyone else has noticed it (I can't find anyone who has)

Accidentally said "endogenous" instead of "pluasibly exogenous" and they kicked me out of econ.
Accidentally said "hard" instead of "non-trivial" and they kicked me out of SF

Will I get a good income out of doing a PhD? Of course not. But will I at least also find a stable job that allows me to pursue my research? Also no. But will I at least be happy doing what I like? Hahaha also no. Sounds terrible. Where do one sign up?
These results suggest that getting a PhD causally worsens mental health, or at least receiving psychiatric medicines. The reversal post PhD degree is particularly convincing. But the up trend among the control group is intriguing. The highly educated are in distress.

I also had AI make a song to go with it. Course materials with a soundtrack.
Using generative AI to massively edit the readings for my undergraduate class. I liked it before, but hopefully this is a lot easier to understand for students.
