I look forward to catching up with folks at the Columbia Economics #ASSA2026 reception on Saturday evening in Marriott Downtown, Room 407. www.aeaweb.org/conference/2...

Expanding on this. The rise of LLMs push the role of data scientists closer to systems engineers and away from coders. Systems engineering is about turning competing stakeholder demands into consensus criteria for judging a solution and coming up with ways to verify whether criteria have been met.

A large UK field experiment—110,000 drivers, 60 percent of public chargers—found that cutting prices by 40 percent increased charging by 117 percent. Consumers respond fast, large grid benefits, from Bernard, Hackett, @rmetcalfe.bsky.social, Panzone, and Schein www.nber.org/papers/w34600

New @nberpubs: "The Impact of Dynamic Prices on Electric Vehicle Public Charging Demand: Evidence from a Nationwide Natural Field Experiment" www.nber.org/papers/w34600 "Our findings suggest that dynamic pricing for public EV charging generated large consumer welfare gains."

Hannah's work shows that, when the minimum wage increases, schedule unpredictability goes up too. Perhaps not surprising (but very hard to show)--as the wage goes up, workers pay in other ways. She is on the market and has a number of very cool and important papers! hannahfarkas.github.io

Super excited to see Hannah's JMP in the Economist this week! She uses detailed data to show how firms pass the risk of weather-driven shift changes on to workers in food & bev / retail, & that minimum wages actual *worsen* that effect! #econsky #climsky #climate #jmp #jmc #susdev

1. Schedule unpredictability means you don't work full time, but can't fill the other hours. Avg hours worked per year in hospitality is 26, compared to 35-40 in most other industries. But workers can't fill the spare hours with another job as they don't know when they'll be scheduled to work.

Hannah also finds a tradeoff between schedule unpredictability and wages: when the minimum wage is increased, scheduling unpredictability increases too. Suggests another margin that firms are able to cut costs on when minimum wages increase. (parallels with our work on workplace injuries).

2. Firms pass demand risk onto workers: Hannah shows that on bad-weather days (when fewer people come to buy things from these retail & hospitality businesses), there are more last-minute shift cancellations. In most jobs, the firm bears the risk of demand shocks unless extreme (-> layoffs).

This is a fascinating paper. It's the first (afaik) to actually document food&drink&retail scheduling unpredictability using actual firm data. It illustrates v clearly why unpredictable scheduling makes these jobs so difficult:

Excited to see my JMP cited in the Economist—it highlights the tradeoffs workers could face with a higher minimum wage and suggests more worker protections like Fair Workweek laws could be important alongside minimum wage increases www.economist.com/finance-and-...

Wow, this is a really interesting #EconJMP

Super cool #EconJMP by Hayeon on policy intensity and loopholes. Check out the paper and her other work at: sites.google.com/view/hayeonj...

I've seen Hannah present and she does great stuff. Check out the thread.

Check out Hannah’s awesome #EconJMP with really cool/unique data that allows for insights into an understudied but important aspect of labor markets.

I’m on the #EconJobMarket! I study labor, extreme weather adaptation, and inequality. My JMP addresses an under-studied aspect of the labor market: schedule unpredictability among hourly workers in the service sector. 🧵👇

I'm happy to share my #JMP on the relationship between policy intensity and effectiveness! It challenges the idea that stricter policies are always more effective by showing that policy avoidance rises with stringency during the early period of implementation. 🧵👇 #Econsky #EconJobMarket #EconJMP

Now that is a cool paper, on how labour markets with hourly workers/zero hour contracts push unpredictability and slow business days onto workers. (She exploits weather and minimum wage variations.)

Meet our outstanding 2025–26 economics job market candidates from @columbiasipa.bsky.social. We have two exceptional scholars on this year’s AP market — both bring awesome and policy-relevant research agendas to the market. www.sipa.columbia.edu/sipa-educati...

Two intense and inspiring months at @columbiasipa.bsky.social have come to an end! It has been an incredibly enriching experience to immerse myself in this thriving academic community — and the kind, curious, and passionate researchers at SIPA made it easy to enjoy every day of my research stay.

Just a reminder to submit your papers to SoLE!!! It will be a great conference, with not-to-be-missed keynotes by Janet Currie, Kerwin Charles, and Jeff Smith! Avoid FOMO and submit! 🥳

This recent working paper by @rmetcalfe.bsky.social e.a. for @centrefornetzero.bsky.social shows how effective automated EV smart charging is: "42% reduction in household electricity demand during peak hours, with 100% of this demand shifted to low-cost, low-emission off-peak periods."

I remember it like it was yesterday.

Very happy to release this working paper today showing the value of AI in helping shape energy demand.

I don’t think I have ever publicly criticized any Presidential nominee before. But E.J. Antoni is completely unqualified to be BLS Commissioner. He is an extreme partisan and does not have any relevant expertise. He would be a break from decades of nonpartisan technocrats.

EJ Antoni has never worked in statistics collection. He is 5 years out of his PhD. He's only ever written one economics paper. His explicit, only qualifications are that he works in ultra-conservative think tanks & believes Trump's conspiracies about the BLS. Grim stuff.
