EconEats — AI restaurant recommendations
From Josh Knox:
The search tool I’ve always wanted – I trained a custom GPT to recommend restaurants based on the rules from [Tyler Cowen’s] An Economist Gets Lunch.

It’s sort of a retroactive EconGoat project:)
I wrote about the experience on my blog.

Strategic CEO Activism in Polarized Markets
CEOs are increasingly making public statements on contentious social issues. In this paper, we examine what motivates CEOs to engage in social activism. We show that CEO social activism is a strategic choice and not necessarily an expression of the CEO’s own political views. Republican-donor CEOs are three-times more likely to make social statements with a liberal-slant. They are also more likely to make social statements when their firm’s operating environment is politically polarized, and when their employees are Democrat-leaning. Such statements are associated with a 3% increase in consumer visits to a firm’s stores in Democrat counties without significantly reducing them in Republican counties. CEO activism is also associated with a 0.12% gain in firm value, increased quarterly sales turnover, and a reduced likelihood of shareholder activism on social issues. Our results suggest that corporate actions that appear to be stakeholder-driven can be motivated by economic concerns.

Weird anecdotes about philosophers connected to Oxford
Here is one:
McTaggart wore his eccentricities with pride. He rode a tricycle. He walked “with a curious shuffle, back to the wall, as if expecting a sudden kick from behind,” a fact that may or may not be explained by his having been bullied at boarding school. He saluted every cat he met. His dissertation for a fellowship at Trinity, later published as Studies in the Hegelian Dialectic; had elicited from that older Apostle, Henry Sidgwick, the remark; “I can see that this is nonsense, but what I want to know is whether it is the right kind of nonsense.” Apparently, it was.
That is from Nikhil Krishnan, A Terribly Serious Adventure: Philosophy and War at Oxford 1900-1960. Another recent book dealing with both philosophy and war at Oxford is M.W. Rowe’s very thorough J.L. Austin: Philosopher & D-Day Intelligence Officer. Here is that book’s best weird philosopher anecdote:
Robert Paul Wolff noted Quine’s frequent lack of small talk, and his tactics for brushing off unwanted questioners, but his deeper doubts were crystallized by an incident some years later:
“Quine obviously had a sensual side to his nature to complement his intellect, as his attractive second wife and his love of food and jazz attested. But I always thought there was some element of humanity missing from his makeup that gave him a rather cold aura. Quine had just returned from a trip to Germany — this was not fifteen years after the war remember — and he was describing a tour he had taken of SS torture chambers. He exhibited an eerie fascination with the technical efficiency of the facility that struck me as devoid of any real human appreciation of its demonic purpose.”
But at Oxford, Quine was perfectly charming, and his erudition and accomplishments — besides logic and jazz, he was an expert on maps, widely travelled, and said to speak eight languages — ensured considerable social success…
As for the broader book, I had not known the extent to which Austin was a significant and highly successful intelligence officer. It is a very good book if you are interested in hundreds of pages on this topic.
The Effect of Public Science on Corporate R&D
We study the relationships between corporate R&D and three components of public science: knowledge, human capital, and invention. We identify the relationships through firm-specific exposure to changes in federal agency R\&D budgets that are driven by the political composition of congressional appropriations subcommittees. Our results indicate that R&D by established firms, which account for more than three-quarters of business R&D, is affected by scientific knowledge produced by universities only when the latter is embodied in inventions or PhD scientists. Human capital trained by universities fosters innovation in firms. However, inventions from universities and public research institutes substitute for corporate inventions and reduce the demand for internal research by corporations, perhaps reflecting downstream competition from startups that commercialize university inventions. Moreover, abstract knowledge advances per se elicit little or no response. Our findings question the belief that public science represents a non-rival public good that feeds into corporate R&D through knowledge spillovers.

We use this tool to construct a detailed assessment of U.S. zoning regulations. We estimate the correlation of these housing regulations with housing costs and construction. Our work highlights the efficacy and reliability of LLMs in measuring and interpreting complex regulatory datasets.” Link here.

MR commentator “Sure” on YIMBY
People talk about YIMBY as though it will mean more high rise apartments. And maybe it would in New York or San Francisco, though I have my doubts.
But what people want from their housing is overwhelmingly a short commute and low density.
Currently, the neighborhoods that offer the best tradeoff for these are the priciest in most metropolitan areas. Georgetown, Arlington, Falls Church, Chevy Chase, Great Falls, McLean … all of them offer shorter commutes into DC (or other key job locations like the Pentagon).
And what have YIMBY’s won? Well in Arlington and Alexandria they can now build multifamily housing in places that were once reserved for SFH.
Suppose they do, who is going to move in? The guys who are buying in Chantilly because they want space? Or the guys crowded into a apartment building in NE DC who work in Foggy Bottom?
I submit it will be the latter.
End of the day, Americans want to live in the burbs and the country. If we liberalize zoning everywhere (i.e. the YIMBY dream) then we should expect a net movement from the areas where people say they don’t want to live to the areas where they say they want to live.
And on net that means out of the urban core and into something less dense. Most likely that means leaving the high rises and moving into low rises or multiplexes. End of the day, it will be moving from high density to lower density.
And this will create tensions between maintaining SFH in burbs as opposed to multiplexing them or building low rises.
I have no idea if the price will be the thing that gives – it may rise because the land has suddenly gotten more valuable for a teardown to low rise conversion. This would bring down “housing” prices, but quite possibly increase the cost of detached single family homes as the supply of that specific housing class diminishes. Possibly, the low rises will reduce demand for SFH more than teardowns and foregone SFH developments.
But if that does happen, it means that a lot of suburban areas are going to have a bunch of new residents and voters who are not keen to live the SFH lifestyle. And that is all but certainly going to mean disamenity for the SFH lifers. That may be new local politics, investment in public transportation at the expense of road maintenance, or declining school quality.
But end of the day, if YIMBYism allows people to live as they want because the market can better match demand, then the net flow has to be out of the oversubscribed cities. And the big reason people say they live urban when they would prefer otherwise is to be close to the jobs. This strongly suggests that YIMBY will end up resulting less in skyscrapering the cities and more in multiplexing the burbs.
Outside of a handful of cities with extremely harsh geographic constraints (e.g. NYC, SF), upzoning the burbs will likely eat into the city cores more than new folks will move to the city cores.
Of course there is always the immigration question. With enough immigration, even the cities will fill (i.e. both NYC and SF are already more than a third foreign born), but if we confine ourselves to current residents they want out and they want a short commute.

The University presidents
Here is three and a half minutes of their testimony before Congress. Worth a watch, if you haven’t already. I have viewed some other segments as well, none of them impressive. I can’t bring myself to sit through the whole thing.
I don’t doubt that I would find their actual views on world affairs highly objectionable, but that is not why I am here today. Here are a few other points:
1. Their entire testimony is ruled by their lawyers, by their fear that their universities might be sued, and their need to placate internal interest groups. That is a major problem, in addition to their unwillingness to condemn various forms of rhetoric for violating their codes of conduct. As Katherine Boyle stated: “This is Rule by HR Department and it gets dark very fast.”
How do you think that affects the quality of their other decisions? The perceptions and incentives of their subordinates?
2. They are all in a defensive crouch. None of them are good on TV. None of them are good in front of Congress. They have ended up disgracing their universities, in front of massive audiences (the largest they ever will have?), simply for the end goal of maintaining a kind of (illusory?) maximum defensibility for their positions within their universities. At that they are too skilled.
How do you think that affects the quality of their other decisions? The perceptions and incentives of their subordinates?
What do you think about the mechanisms that led these particular individuals to be selected for top leadership positions?
3. Not one came close to admitting how hypocritical private university policies are on free speech. You can call for Intifada but cannot express say various opinions about trans individuals. Not de facto. Whether you think they should or not, none of these universities comes close to enforcing “First Amendment standards” for speech, even off-campus speech for their faculty, students, and affiliates.
What do you think that says about the quality and forthrightness of their other decisions? Of the subsequent perceptions and incentives of their subordinates?
What do you think about the mechanisms that led this particular equilibrium to evolve?
Overall this was a dark day for American higher education. I want you to keep in mind that the incentives you saw on display rule so many other parts of the system, albeit usually invisibly. Don’t forget that. These university presidents have solved for what they think is the equilibrium, and it ain’t pretty.
Gun Buybacks and the Elasticity of Supply
Can gun buybacks work? Some simple economics suggests, no! The first of our videos on the elasticity of supply, Why Housing is Unaffordable, illustrated inelastic supply. Today’s video on gun buybacks illustrates elastic supply. Our gun buyback video hits the sweet spot for MRU videos—solid economics leading to surprising conclusions illustrated in an entertaining and accurate way.
Of course, both of these videos draw upon and pair great with our textbook, Modern Principles of Economics.
Differential fertility makes society more conservative on family values
“Family values” conservatives in the United States have more children and more siblings than their compatriots. These patterns reflect the tendency of the more religious and less educated to have larger families and more conservative views on the family. Among Protestants, denominational differences play a role, with fundamentalist groups exhibiting larger families, less education, and greater conservatism. The causal pathways are unclear, but the patterns reshape society: Traditional-family conservatism is more prevalent than it would have been if each person had the same population share as his or her parents. This demographic phenomenon raises opposition to same-sex marriage and abortion by 3 to 4 percentage points. It accounts for 7.9 million of the nation’s 54.8 million opponents to same-sex marriage.

European inflation was more painful for the elderly
That is the topic of my latest Bloomberg column, here is one bit:
As recent research indicates, the recent inflation has been very costly. The 2021-2022 inflation cost more than 3% of national income in France, Germany and Spain, and about 8% of national income in Italy, higher costs than what a typical recession would bring.
It is striking how much those costs fall on the elderly, which is one reason that lowering inflation rates has been such a priority. The elderly usually have the most accumulated savings, and less time to make up for inflationary losses by subsequent compounding. Older people are also more likely to own homes, so face higher home heating bills when energy prices rise. Overall, in the last several years, a low-income retired household in Italy might have taken income cuts of up to 20%, while a middle-aged household in the euro area might have seen a typical income cut of 5%.
…Not everyone lost from the inflation. Young households in Spain, for instance, gained more than 5% in income. The simplest way a household might gain from inflation is that its debt liabilities decline in real, inflation-adjusted value. On average, the young are more likely to be in debt than the elderly, and own fewer assets. Inflation also tends to lower the value of tenured jobs, such as in academia, and younger people are less likely to hold such posts. The young also tend to have more time in their lives to adjust to negative economic shocks, by for instance geographic or career migration.
Overall, an estimated 30% of the households in the euro area gained from the inflationary shock. Almost half of 25- to 44-year-olds benefited.
On net, the inflation remains a clear negative. But how many other eurozone policies manage to favor the young?

The Swiss convexify the choice set
Could you really go for exactly one McDonald’s Chicken McNugget right about now? Well then, hop over to Switzerland and chow down!
Working with TBWA, local McD’s are tapping into a mathematics-themed meme by offering a single-McNugget selection to celebrate the menu staple’s 40th birthday.
Fans love to indulge in jokey theorems about the breaded bites of bliss. There’s also intense competition over who gets the final McNugget.
This campaign goofs on the whole numerical bit. Plus, per press materials, “Everyone gets the last nugget.”
…Each special Nug sells for 1.20 Swiss francs while supplies last. A regular box of four costs 4.80.
