]]> Worth seeing, and I enjoyed it — but a few observations I haven’t seen elsewhere.

For all the praise of IMAX and 70mm’s supposed clarity, several scenes are out of focus on the actor. Pulling focus is harder with a large-format negative. The problem is compounded by Nolan’s fondness for darkness: too many scenes are dark enough to squander much of what the format offers. The sound was earth-shaking in the way we have come to expect from Nolan but there is no song.

The “woke casting” controversy is a non-issue — barely noticeable in practice. The film is obviously conservative in temperament. Helen gets some of the best lines, and Nolan’s slight disfigurement of her traditional arc is exactly right. The Circe scene is the best in the film.

Tyler is entirely wrong about Calypso. Odysseus’s seven years with her were among his most enjoyable. I have no doubt about this.

The deeper flaws are structural. Nolan loves to play with time, and the resulting flashbacks and memories ironically shortchange the odyssey itself — making the journey feel shorter and less arduous than it should. This is very much in the mode of Interstellar: a sequence of set-piece locations strung together. One planet/one monster/one scene–on to the next. But Odysseus as a character on an odyssey never quite coheres.

We are told repeatedly that Odysseus is smart but we shouldn’t need to be reminded. Odysseus is both beloved and resented by gods, a man whose men will follow him to the ends of the earth and then betray him but Mat Damon just doesn’t bring it. Things happen to him; he responds stoically. What we needed was the equivalent of Kirk defeating the Kobayashi Maru — a moment that makes the audience understand, viscerally, that this man bends the rules and contends with the gods by the sheer force of his wit and will. Of courses the Trojan horse is this but Nolan treats this as something of which Odysseus is ashamed and the other clever bits are downplayed. Damon never gets his Kobayashi Meru. The odyssey is a slog, rather than an adventure. Could have used a bit more Sinbad, a bit less Dark Knight. The dialogue, as Tyler noted, is lame. 

Not Nolan’s best film but still better than most films and for scale, ambition, and grand themes well worth the 3-hour investment.

We estimate the causal impacts of GLP-1 treatment on labor market outcomes using linked Danish administrative data and a matched stacked difference-in-differences design. We compare patients who initiate GLP-1 treatment during the first two years of Semaglutide availability to observably similar patients who initiate four years later. We find that GLP-1 treatment reduces long-term sickness leave by 17.3%. We estimate total fiscal benefits of GLP-1 initiation of approximately 1.3–1.5% of annual labor income per employed individual. We do not detect statistically significant or economically meaningful impacts on income, labor force participation, or employment over four years.

That is from a new NBER working paper by N. Meltem Daysal, Camille JH. Fredrickson, Ida L. Kristiansen, Mircea Trandafir & Jonathan Zhang.

]]> Any time you hear claims about American government, a sanity-inducing response is to ask whether they also are true of state and local governments.  Here is an excerpt from my latest piece at The Free Press:

First, in people’s daily lives, they typically interact with their state and local governments more than with the feds. And if you look at what state and local governments do, most of it is driven by voter demand, and I do not mean billionaire or oligarchic voters.

Most state and local government spending goes toward schools, roads, and increasingly, Medicaid. None of those reflect the agendas of most billionaires. For example, Medicaid dollars flow particularly to lower-income recipients. Hospitals and doctors receive income from this program, but reimbursement rates are relatively low, and many of the best doctors do not accept Medicaid patients and don’t make a living from the program.

Somehow the oligarchy saw fit to leave these expenditures alone.  Looking at the state and local level also suggests that America — with some notable exceptions — is better governed than before.

The strategy for China is obvious: commoditize your complements. Note that Xi explicitly ties openness to AI “moving from the digital world into the physical world”; the physical world is the world dominated by China, and the country’s lead in areas like robotics is going to massively benefit from widely available AI models.

Along the same lines, China does not want the U.S. to gain an asymmetric advantage in AI; to the extent that China can weaken the U.S. frontier labs while strengthening any and all potential U.S. adversaries so much the better, and it can benefit from the innovation that will attach itself to an open ecosystem.

And in sum:

The better course is clear: first, loosen Fable and Sol restrictions on cybersecurity, and second, ensure that U.S. open weight model makers are on an equal playing field with China. Yes, the frontier labs will kick and scream about this, but the Administration should realize that listening to their histrionics has led the U.S. to a position where U.S. companies are dependent on China for their defenses. Let the frontier labs win by being better; don’t let them define safety or security, or pull up the ladder of humanity’s collective knowledge. China is already hard enough to compete with; letting them carry the standard for openness and innovation is simply giving away our biggest advantage.

That is from Ben Thompson’s Stratechery (gated, but ungated link here).

Was everyone happier and better off back then?  Did they have deeper understandings of the world?  Did they treat each other like heartless beasts?  Would you eschew one of their parties and stay at home and scroll Twitter?  You can watch this film and ponder those questions to your heart’s content.  Alternatively, you could go to a debutante ball, which it turns out still exists.  Which of those has been your choice?

We estimate the extent of workplace political segregation in the United States by merging data covering over 45 million workers. We present four main findings. First, partisans are segregated by workplace. The average Democrat’s coworkers are 11.7 percentage points (pp; 95% confidence interval (CI) [10.6, 12.8]) more Democratic than the average Republican’s. After controlling for geography, industry and occupation, segregation is 2.9 pp [2.7, 3.1], comparable to analogously estimated gender segregation (2.8 pp [2.6, 3.0]). Second, segregation is largest among the politically active (political donors: 14.8 pp [13.2, 16.4] versus non-donors: 11.6 pp [10.5, 12.7]) and those with more market power (senior executives: 14.7 pp [13.4, 16.1]). Third, Republicans experience higher exposure to Democrats than vice versa: the average Republican’s coworkers are 50% Democratic versus 32% Republican for the average Democrat. Fourth, political segregation has changed little over time (2012: 11.1 pp [10.0, 12.2] versus 2024: 11.0 pp [10.0, 12.0]).

That is from a recent paper by Justin Frake, Reuben Hurst, and Max Kagan.  Via the excellent Kevin Lewis.

Peter Brook‘s five-hour-plus film adaptation of “The Mahabharata” is set for a BFI Blu-ray release on Aug. 10, presented in high definition from a new 4K restoration of the 1989 production.

The release centres on the triptych version of the film, running 332 minutes, which sits between Brook’s three-hour cinema cut and the six-hour television version he shot concurrently. Based on the ancient Hindu epic, the film was originally produced by Brook with screenwriters Jean-Claude Carrière and Marie-Hélène Estienne, and features an international cast drawn from 16 nationalities.

Here is the Variety article, but will there be a version suitable for U.S. players?  The work is highly recommended, real genius.  For the pointer I thank Sam Mendelsohn.

…high-end developments unlock long housing chains. As higher-income households move into newly built units, they free up older properties, raising supply and slashing prices for middle- and lower-end housing through a process known as filtering. Numerous international studies underscore this positive ripple effect.

One published last year tracked households that moved into a newly built 512-unit condominium tower in Honolulu, Hawaii. It found that the building created at least 557 vacancies in older and cheaper apartments across the city in just three years, with market-rate units more likely to release the largest chains.

Filtering can also be widespread. A 2021 study in Helsinki using geo-coded population data found that every 100 new market-rate units in the city centre led to around 60 units becoming available in the city’s bottom half of neighbourhoods by income. An analysis across all homes in Sweden over several decades concluded that “new homes, even those initially primarily inhabited by rich people, lead to substantial trickle-down effects that also benefit the poor”.

Other US studies highlight how market-rate developments benefit less well-to-do local residents by lowering housing costs. In San Francisco, a 2021 paper found new developments lowered the risk of eviction notices for residents in rent-stabilised housing. Even “luxury” developments in New York City — which Mamdani has criticised — have been shown to contribute to lower local rents and sales prices.

Recently in a private conversation I suggested that Nabeel Qureshi be cast as the next James Bond.  He has a British accent, was born in (northern!) England, is tall and is good-looking.  He does not remind anyone of Roger Moore.  He is old enough where you could believe he has some experience as a spy, and at the baccarat table, but young enough where he could do those stunts without it seeming ridiculous.

I recall the talk of a black Bond, a notion which likely would end up dull and cliched.  But a Bond of Pakistani ethnic origin?  Now that would occasion some debate.

I am not saying it always works.  I likely would object to a remake of Zulu with an all-Chinese cast.  Or there can be major cultural mistakes which are not cross-ethnic, such as casting a Liverpudlian in the role of a London elite.  Everyone in The Sopranos should at least be pretending to fit their roles, and indeed Tony himself grew up in New Jersey.  I would have done fine in a cameo role.

]]> I would not trust the results of this (or any) paper on this topic very much, but it is good to see some inquiry along different dimensions than the usual:

Past research explored the beneficial and harmful effects of social media (SM), but no study has investigated how SM might change people’s identities. Authors suggest that SM is a catalyst for a shift in two individual values, achievement and conformity, transforming the fabric of our societies. A difference-in-differences analysis found that countries with higher SM adoption compared to their culturally similar country show an increase in achievement and conformity orientation. Next, authors manipulated SM use and established a causal link between SM use and the activation of achievement and conformity values in Facebook users. These findings were replicated with objective SM usage data, and the pertinent mechanism was explored: people’s SM use increases achievement and conformity orientation through an increased need for approval, particularly for those who self-ruminate. Findings suggest that SM use contributes to the emergence of a societal culture that places an emphasis on achievement-seeking and conformity.

That is by Ertugrul Uysal, Sascha Alavi, and Valéry Bezençon. Via the excellent Kevin Lewis.
