The lowest-hanging fruit is to simply legalize selling groceries in more of the city. The most egregious planning barrier is that grocery stores over 10,000 square feet are not generally allowed as-of-right in so-called “M” districts, which are the easiest places to find sites large enough to accommodate the large stores that national grocers are used to. Many of these districts are mapped in places that are not what people have in mind when they think “industrial” — mixed-use neighborhoods with lots of housing like stretches of Williamsburg’s Bedford Avenue and almost all of Gowanus, even post-rezoning, are in fact mapped as industrial districts.
To open a full-sized grocery store in these areas, a developer must seek a “special permit,” which requires the full City Council to get together and vote for an exception to the rules. This is a long, uncertain process, and has in the past even been an invitation to corruption.
Most famously, the City Council uses this power to keep out Walmart at the behest of unions and community groups. Thwarted in its plans to open a store in East New York — a low-income Brooklyn neighborhood that could desperately use more grocery options — the nation’s largest grocer instead serves New Yorkers with a store just beyond the Queens/Nassau line in Valley Stream, rumored to be the busiest Walmart in the country. New Yorkers with a car and the willingness to schlep beyond city limits — or pay the Instacart premium — get access to cheaper groceries; the rest get locked out.
When politicians are willing to approve a grocery store, the price can be high.

This is what I’m seeing: + 2.4 million rent-controlled apartments in a city with a massive housing shortage and 1.4% vacancy rate.
+ A huge % of these tenants are wealthy, white boomers using the units as pieds-a-terres while they spend their weekends and summers elsewhere.
+ Meanwhile, the government is using rent control to purposely drive down the value of multifamily housing, so that it can be purchased in a fire sale by the government.
+ The small-time landlords with big rent rolls of “stabilized” units are going under. Their portfolios end up in the arms of PE and foreign money (how are Progressives okay with this?) The banks will get hit by this too.
+ Because there is such a reduction in supply (~40% of units are price-controlled), leftover supply is ~33% more expensive + Because NYC gov is not friendly towards landlords, there is a lack of development –> even less supply
+ Rich and homeowners overwhelmingly support these laws b/c it drives up the value of their condos & co-ops (less supply –> higher prices for condos)
+ Big PE companies like these policies b/c they can buy buildings in fire sales and wait for rent control reform (5-10 years out)
+ Meanwhile – ~2.4 million units are rotting and won’t be brought up to code as tenants leave b/c the numbers don’t pencil –> 50k “ghost apartments” padlocked off market now, maybe 100k soon
+ Gen Z and the working class continue to vote for these policies, hoping they will be among the lucky few to win the lottery ticket of a rent-controlled apartment
+ Meanwhile, boomers hang onto their units and pass them to their children, family members, etc. –> NYC’s housing stock is rotting slowly, going offline, and becoming more expensive

2. Does AI mean the demands on labor go up?
3. This obituary has plenty of interesting information about South Africa’s nuclear program (NYT).
4. Mercatus 1991 fellowship on state-level Indian economic policy.

6. “I find that parental transfers account for 13 percentage points (27%) of young households’ homeownership…Finally, I show that children of wealthy parents strategically use the illiquidity of housing as a commitment device to encourage transfers, resulting in a preference for illiquidity.” Link here.

They exist in manufacturing too, and perhaps this should help you feel a little better about American problems:
A January 2024 report on China’s wind power sector by researchers at Tsinghua University found that it remained heavily dependent on imports for crucial parts — including 60 per cent of the bearings that support their rotors, 70 per cent of the transistor modules used to convert power into grid-compliant electric current, and 100 per cent of logic modules used to control turbines in real time…
Consider lithium, cobalt, and manganese, three minerals used heavily in electric car btteries. The Chinese shares of global refining for these materials is overwhelming…But far smaller amounts of the raw materials come from mines in China – just 22 per cent, 3 percent and 4 per cent, respectively.
That is from Simon Mundy at the FT.

In 2004 (!) I wrote:
Many people complain that medicine is too impersonal. I think it is not impersonal enough. I have nothing against my physician (a local magazine says he is one of the best in the area) but I would prefer to be diagnosed by a computer. A typical physician spends most of the day playing twenty questions. Where does it hurt? Do you have a cough? How high is the patient’s blood pressure? But an expert system can play twenty questions better than most people. An expert system can use the best knowledge in the field, it can stay current with the journals, and it never forgets.
It took longer than it should have, but we are finally here. Today, most people already use AI to help diagnose and manage medical conditions, and now:
Utah is letting artificial intelligence — not a doctor — renew certain medical prescriptions. No human involved.
It’s a pilot program for routine renewals but a welcome start. The AMA, of course, is not pleased.
In a statement, Dr. John Whyte, CEO and executive vice president at the American Medical Association, said: “While AI has limitless opportunity to transform medicine for the better, without physician input it also poses serious risks to patients and physicians alike.”
One concern is misuse or abuse, including the possibility that people struggling with addiction could try to game automated systems to obtain drugs inappropriately. Another concern is missing subtle clinical red flags or drug interactions that a doctor would catch.
It’s amazing that anyone can say these things with a straight face. As far as I know, AI has never run a pill mill, unlike human physicians. And the AI
“missing subtle clinical red flags or drug interactions that a doctor would catch.” Is this a joke?

Russia is preparing a new economics textbook for university students that aims to challenge what its authors call a “myth” that democracy drives economic growth and to revive the socialist economic theories of Soviet leader Josef Stalin, the head of a Kremlin-linked advisory body said.
Moscow has ramped up efforts to enforce its view of history and global politics in schools since launching its full-scale invasion of Ukraine in 2022, introducing mandatory patriotic classes and rewriting history curricula to align with the Kremlin’s wartime narratives.
Valery Fadeyev, chairman of Russia’s presidential human rights council, told the RBC news website that he is leading work on the textbook, which could be introduced as early as the next academic year for students of sociology, political science and history.
The 350-400-page book, tentatively titled “Essays on Economics and Economic Science,” is intended to present a broader view of economic development than mainstream liberal theory, Fadeyev said.
Here is the full story, via Frank W. The Kyiv School of Economics it ain’t…
