Given the news today that Spirit Airlines is shuttering and thousands of people are losing their jobs, I think we should honestly assess whether the Garland DoJ stopping the JetBlue merger with Spirit Airlines was the right call. Perhaps it was but any analysis must consider as part of the equation the loss to so many families ro decide.

@SinaiLawFirm @JoeFernandez It’s the combination. Low property taxes make it easy to just hang onto, and inability to evict tenants make people not want to rent it out.

One thing I see in my neighborhood in LA with Prop 13 is that there are at least 8 houses in a 2 block radius that have been empty for 5+ years. People who owned them have passed and it's so cheap for their kids just to leave it sitting. Bad for the neighborhood and city

@rohindhar Yeah, you’d much rather have 80s or 90s electrical vs. 40s and 50s.

In the San Francisco real estate market, one of the best deals is homes that were updated in the 1990s or 2000s and are now for sale and look dated On homes like this the infrastructure behind the walls is already updated, so as a buyer you typically don’t have to spend money on new electrical, foundation, plumbing, structural elements, etc. These items are terribly expensive and mostly behind walls so you never even see them. Instead, if you want to update it, can focus on cosmetic elements which are both fun and less expensive. But for the most part, buyers really don’t like homes that don’t show well so the 1990s remodel home gets dismissed quickly often for a less expensive “blank slate” fixer, that ends up being much more expensive when you “fix it” This dynamic is true at all price points, but particularly common at the higher end where buyers prefer a perfect home (which rarely comes to market) so end up opting for a fixer (which ends up taking 4 years to complete)

@mattyglesias I think a lot of people buy the car seats that work from infant to 7 years old, which are indeed huge.

Good post on study design Using Lyft data, they compared drivers traveling at same speeds, on the same roads, at the same times. Disappointing result: Minority drivers 24–33% more likely to be cited and paid 23–34% higher fines, not explained by differences in accident risk.
John A. List@Econ_4_Everyone

The most likely interaction any of us will have with the police is a traffic stop. That simple fact accentuates the import of the following question: when an officer decides to pull someone over, does race play a role? It sounds like a straightforward question. It is not. And the reason comes down to a measurement problem that has haunted this literature, and many others, for decades. What do you need to properly explore this question? Three numbers: i) how many minority drivers were stopped, ii) how many minority drivers were on the road, and iii) how many minority drivers were actually speeding. Knowing all of these is a tall task, especially knowing who was speeding among those who were never pulled over. I call this the denominator problem and measuring discrimination critically relies on solving it. Prior research has a bunch of creative: veil-of-darkness designs, daytime versus nighttime comparisons, benchmark approaches using census data. All clever. Yet, they do require certain assumptions that everyone is not comfortable making. A paper that I just talked about at our student visitation day this past Friday (and I will talk about this week in my Economics for Everyone course) solves it differently. When I was back at Lyft, we leveraged records on the GPS location of every driver every few seconds. That gives us actual driving behavior — speed, location, time — for over 200,000 drivers before any police interaction occurs. We matched those records to official Florida speeding citations secured through a Freedom of Information Act request (kudos to Florida, still the only state to adhere to our FOIA). As far as I know, this is one of those rare occurrences where we have solved the denominator problem: who was on the road and exactly how fast are they driving? Guess what we found? You can find out here (it is depressing so I am not going to recount it): ideas.repec.org/p/feb/natura/0… But the broader lesson I want to make with my students is that the denominator problem is not unique to discrimination research. It shows up everywhere in social science. Hiring discrimination studies rarely observe the full applicant pool and almost never observe underlying qualifications. Health disparities research cannot see who never sought care. Criminal justice research fights this at every turn. The general insight is this: selection into measurement is itself the phenomenon you are trying to study. In certain cases, partnerships with organizations can help to solve that key issue.

It’s so frustrating to me that “Order of Operations” used to be considered such a common concept understood by most middle schoolers. Now, it’s entirely unknown to many people, so bait accounts can endlessly post this slop & have people fight over 2 answers that are both wrong.

Today on a flight, there was a baby crying for about an hour and a half straight. That happens. You expect it. But in this case it was crying because the mother refused to allow her to fall asleep. The dad tried to get the mom to let her sleep, with no success. “If she sleeps now, she won’t go to sleep tonight… and we’ll be up late.” She would rather have 150 people sit there listening to her baby cry for an hour and a half… …than deal with an extra hour and a half later tonight herself. Incredible.

A major reason I don't trust Claude to do its own statistical analyses yet is because sometimes you can just ask it 'Is that right? Seems wrong.' and then everything it's written so far changes. It's not very thorough and will tell you and update to obviously erroneous things.

Gavin Newsom doubled spending on California food stamps. Romanian fraud rings immediately started stealing millions from the program. Instead of cracking down, however, State Democrats want to reduce the penalties—effectively legalizing welfare fraud.

@DarwinBondGraha The old fare gates were ridiculously easy to bypass. Every single time I took Bart I saw someone evading fares.

There have always been fare gates. Throughout its 50+ year history, BART has been one of the most successful and self-sustaining transit agencies in America. Its current problems are rooted mostly in economic changes affecting all metro areas.
Noah Smith 🐇🇺🇸🇺🇦🇹🇼@Noahpinion

Instead of a dying service that needs constant bailouts because it lets junkies and creeps ride for free, BART should install fare gates everywhere and be a thriving public transit system that working class people can use to get around without a car.

@kane I think we should pay our politicians more to attract better people (as opposed to the independently wealthy, crazies, and grifters). But agree that the optics here are pretty bad.

The number of people I encounter who can’t explain their (generally “good”) jobs and/or what their spouses do is staggering. I’d love to see people try to describe what they actually do for a living in a single 280 character tweet in a way that the average person can understand.

There’s like maybe a maximum of 8 jobs where I understand what the job is. Shopkeeper. Farmer. Teacher of some kind. Priest. Novelist. Journalist. Private detective. Chef. That’s it. What is a data engineer. I don’t know.

@bubba371 @shipwreckedcrew I don’t follow. Aren’t you removing the cheap seats? The premium seats just move to the new sidelines. And everyone recalibrates from there?

@shipwreckedcrew Making the court wider won't happen in any professional league, because it would require removing premium seats. Even though both the NHL and the NBA have fields that are clearly too narrow

It should acknowledge the advance of time and development of the modern athlete. Soccer and baseball use smaller fields/goals for younger players. Basketball should make the court 30 feet longer and 12 feet wider, raise the hoop to 12 feet for college and pros, move the 3 pt line back 4 feet, make the free thrown 18 feet, and make the lane 4 feet wider. High school and NBA courts are basically the same size -- NBA is 10 feet longer but same width. Football needs to do the same thing -- 120 x 70 yard fields. Defensive players are so big and fast that the size of the field become an extra defender. Room in the middle of the field has simply evaporated.
David Marcus@BlueBoxDave

I think the NBA should eliminate the 3 pointer. It would be a vastly more attractive sport.

This is also why Zohran’s free bus scheme is bad. It’s not about the revenue, it’s that you want some friction to keep anti-social behavior out of the system.
meatball times@meatballtimes

wait this graph is crazy BART installed anti-fare-hopping gates and the amount of station maintenance and cleanup they had to do went to basically zero strong evidence that the poor condition of public transit is fairly easy to fix + caused by a very small group of people
