Description of the figure: AI intensity across European regions (left panel) and the cumulative change in the labour share between 2000 and 2017 (right panel). In regions with higher AI intensity, the labour income share tended to decrease during the overall time span. The swift rise of artificial intelligence is raising fundamental concerns about the future of work. This column uses data from 238 regions across 21 European countries to examine how AI-related innovation influences the distribution of income between labour and capital, and among different skill classes of labour. Regions with more intense AI patenting tend to experience a decline in the labour share of income, especially in areas with a strong industrial base, indicating that AI acts as a capital-biased innovation. Without appropriate policy intervention, this trend could exacerbate existing inequalities.

Antonio Minniti, Klaus Prettner, Francesco Venturini, & David Bloom find that European regions with more intense #AI patenting tend to experience a decline in the labour share of income, indicating that AI acts as a capital-biased innovation.

Plot with error bars of change in traffic fatalities versus day relative to album release

bar plot showing the number of traffic fatalities on "Non-album release days" and "Album release days"

US traffic fatalities increased 15% on the release days of the top 10 most-streamed albums. That's 18 more deaths per day

Based Bears proposed uses at AH, I estimate the value of the property assessment freeze to the Bears in HB2789 is worth about $2b over 30 years, or $67 million a year before PILOT. I low ball multiple things to create lower limit. I wouldn't be surprised to see the est closer to $3b at build out.

This is on a different planet when it comes to bad analysis.

We have a contender for the wrongest thing written on the internet this week. Economists will tell you *the exact opposite* of this.

Following a trip to the Second Circuit on an appeal by Defendants of the Court’s March 1, 2023, Order at Dkt. 76 (“March 1 Order”), which resulted in an appellate decision favorable to Plaintiffs, Plaintiffs filed a motion asking the Court to reconsider aspects of the Court’s March 1 Order that were adverse to Plaintiffs (and thus were not appealed by Defendants). Dkt. 153. Plaintiffs’ Motion is GRANTED. Defendants’ Motion to Compel Arbitration at Dkt. 47 is now DENIED in full. All of the claims of Plaintiffs Brian Flores, Steve Wilks, and Ray Horton against the NFL and various member teams may now proceed in this Court.

FOOTBALL & RACE 🧵
1/ Four years ago, Brian Flores sued the NFL alleging that the "Rooney Rule" requiring teams to interview minority candidates for head coaching vacancies is a sham.

Today, the judge ruled that ALL claims must be litigated, not arbitrated.

World Cup hosting expected to bring global attention, economic boost to Cobb MARIETTA — After a busy year of hosting major sporting events in 2025, Cobb and Atlanta’s hosting duties will catapult to the global level this year when the FIFA World

Why do these stories persist? Megaevents have been well-studied by economists and determined that the economic impacts are tiny. And any increase will barely ripple out to Cobb. Yet, this is the banner headline in today's MDJ.

We've got to start electing better people. There is zero legitimate policy justification for this. Oregon voters probably don't like this either. Vote these incompetent jerks out.

The Physician-Patient Match and Health Inequality Abstract. This study explores the impact of primary care physicians’ childhood socioeconomic status (SES) on their patients’ health and socio-economic inequality in health. We measure physicians’ SES by their parents’ education and find that SES concordance decreases low-SES patients’ mortality substantially, while high- SES patients’ mortality does not depend on their physicians’ family background, resulting in a reduction in the SES-mortality gradient of 25%. SES concordance improves low-SES patients’ health by increasing care at the intensive margin, increasing detection of chronic conditions, and improving adherence to treatment. SES concordance elevates communication, fosters empathy and trust between physicians and low-SES patients.

Your reminder that local elections matter, and we need to elect better people. This is *indefensible* public policy. There's no reasonable expectation that spending $250 million of taxpayer money to upgrade an NHL arena might promote community welfare. None.

Primary event study from Bressler and Cui (2025). The effect of the "701" Planning Assistance Program is a 13% reduction in new housing supply per decade .

Why are many U.S. cities building less? Why have they insisted on a "thicket" of regulations that make housing hard to build?

In a new #EconJMP with Beau Bressler (beaubressler.github.io), we study how much of the answer lies with a forgotten federal program that taught cities to restrict growth

It’s always fun to do papers on more unique sports. I’ve got some F1 papers, a billiards paper, and now a bull riding paper.

We build a hazard model of buckoffs using bull and rider characteristics. We find that more experienced riders and more difficult bulls affect buckoff likelihood. But both riders and bulls appear in multiple events. Riders who pair with familiar bulls are less likely to be bucked off. Cowboys learn

Many moons ago this was my JMP, so it’s cycled between being my pride and joy and my mortal nemesis, but I’m glad it’s finally published. A ton of people need to be thanked and acknowledged for getting this thing published

What’s the relationship between IPV and elections for the most recent elections? Why is this effect most prominent on Election Day and not the day after, when results are more likely to come in? Do these results hold for gubernatorial or congressional elections? Could we look at other crimes?
