New in @theslingutah.bsky.social, @halsinger.bsky.social and Jacob Linger examines how antitrust enforcers and courts will think about market definition in the pending Netflix-Warner Brothers merger. www.thesling.org/the-netflix-...

I have a new piece on The Sling explaining how algorithms on Amazon work to "raise prices 24/7". Key point: repricers "wait their turn" to get the Buy Box, then hike prices while matching each other. Who loses? Consumers. www.thesling.org/how-algorith...

In his latest, @halsinger.bsky.social explores how Airbnb provides homeshares a common pricing algorithm, called “Smart Pricing,” that serves to coordinate pricing of rental units on its platform. Check it out! www.thesling.org/the-antitrus...

This @nytimes.com article adds useful context to the trend I discussed in @theslingutah.bsky.social . Well worth a read. www.nytimes.com/2025/12/08/t...

In our latest Slingshot, @halsinger.bsky.social and Darren Bush interview @superwuster.bsky.social about his new book, The Age of Extraction, and Tim’s recent NY Times opinion piece on the Facebook-Instagram decision. Go give it a listen—and then go read his book! www.thesling.org/video/slings...

“[W]ith each unprofessional, craven political stunt Chair Ferguson pulls with the FTC…Chair Ferguson burns the FTC’s credibility.” I wrote in @theslingutah.bsky.social about the FTC’s recent comments about Judge Boasberg. www.thesling.org/the-attack-o...

Ted Tatos has a new piece in @theslingutah.bsky.social explaining why a 50-year mortgage, the new proposal from the White House, doesn't create more home owners, just maybe more mortgages and more interest payments. Check it out! www.thesling.org/a-50-year-mo...

Advocates will pounce on a Nobel prize in economics to promote their policy agenda. They find a strand of the work by the winners, spin it into their narrative, and voila, their pet theory is proven right. My latest on the meaning of this year’s Nobel prize. www.thesling.org/deciphering-...

In a new piece, Peter Carstensen, Emeritus U. of Wisconsin Law Professor, explains that if the Union Pacific-Norfolk Southern merger is allowed, there should be separation between ownership of the tracks and operation of the freight services on those tracks. www.thesling.org/to-preserve-...

The latest Slingshot features Erik Peinert, professor of political science at BU and author of the new book, Monopoly Politics. We discussed whether antitrust enforcement will go dormant again, or whether anti-monopoly politics are here to stay. Enjoy! www.thesling.org/video/slings...

No, progressives aren't pushing degrowth. Read our @dylangyauchl.bsky.social's latest in @theslingutah.bsky.social! www.thesling.org/the-hollowne...

I am on a mission to get the business press to stop blaming consumers for industrywide price hikes, and instead look at the companies actually setting prices. Or in the case of Vegas hotels, companies turning over their pricing decisions to a common pricing agent. www.thesling.org/why-did-hote...

New on The Sling: Seth Frotman writes about the common interest of small business, workers, and consumers: Fighting corporate abuse. Check it out! www.thesling.org/standing-wit...

"Letting Google keep right on engaging in most of its harmful conduct entails real costs for consumers and society at large. This remedies opinion consciously chooses to inflict those costs based on a “hope” of good things happening in the future" 🙈

DDC Judge Sooknanan rightfully blocked the FTC’s CID to @mmfa.bsky.social as unconstitutional. The opinion is worth a read ecf.dcd.uscourts.gov/cgi-bin/show...

www.thesling.org/major-league... My latest for The Sling is a classic story! Nearly 20 years ago, we argued in The Wages of Wins that baseball doesn't need salary controls because money can't buy happiness. And here we are again! Good to be playing the old favorites! @halsinger.bsky.social

Warning: To prebut arguments from defenders of price-discrimination, I used figures and basic welfare concepts. Apologies in advance. Delta’s execs told us this month that the AI-based strategy is *increasing* unit revenues. That really should end the debate on output effects.

If Delta were implementing AI-based personalized pricing on its own, that would be bad for travelers. That Delta is using a common algorithm from an GenAI airline pricing consultant makes it even worse. My latest here: www.thesling.org/deltas-ai-ba...

I have a new piece up at @theslingutah.bsky.social, co-authored with Gavin Sicard, that examines whether Big Tech and Microsoft in particular has shared any of the AI-based productivity gains with its workers in the form of higher wages. Lots of cool graphs. www.thesling.org/microsoft-sa...

Calls to deregulate permitting can’t be divorced from the energy-intensive data center boom being fueled by AI and crypto. By our @kennystancil.bsky.social in @theslingutah.bsky.social www.thesling.org/why-big-oil-...

New piece by @halsinger.bsky.social: the next Democratic campaign should focus on the replacement of lost government jobs and the creation of new government jobs, not government spending. Check it out! www.thesling.org/skip-the-spe...

In @theslingutah.bsky.social, I argue Chair Ferguson has sacrificed the FTC's credibility and independence by pursuing Musk's vendetta against @mmfa.bsky.social. I am deeply disappointed in the agency where I began my career. www.thesling.org/the-ftc-shou...

As Musk and Trump dismantle the federal government, corporate power is going unchecked. But all is not lost. In my latest op-ed in @TheSlingUtah, I lay out how states still have powerful tools to fight oligarchy—and protect democracy. Here's what they must do 🧵

The One Agency Act is a good first step. But it does not go far enough, argues Darren Bush. Let's create the Zero Agency Act and make antitrust enforcement efficient. #Antitrust #Econtwitter www.thesling.org/the-zero-age...

www.thesling.org/the-wnba-lab... I wrote an article for @theslingutah.bsky.social on the labor dispute that appears to be coming to the WNBA. A brief thread on why this dispute is all about the choices the NBA is making. ht @halsinger.bsky.social
