Artificial intelligence and the future of Wikipedia

 Jimmy Wales, interviewed in the Guardian:

‘People thought I was a communist doing this as a non-profit’: is Wikipedia’s Jimmy Wales the last decent tech baron?  by David Shariatmadari 

"Musk’s hostility aside, does Wales see artificial intelligence in general as a threat? If people are increasingly relying on AI summaries, might Wikipedia’s dominance turn out to have been a blip? “I don’t think so,” he says, “but, I mean, that’s obviously on a lot of people’s minds these days.” It would be ironic, given that the site’s free licensing model means it can be used by anyone for anything – including as training data for large language models. “There are definitely threats to the web, but they’re not necessarily coming from AI,” he says. “I think the bigger threat is the rise of authoritarianism, governments, regulations, which make it harder to have a truly open global web where people are free to share ideas.” It’s true that Wikipedia is blocked in China, and faces sporadic censorship in Russia and elsewhere. Wales’s stance on this is not to give an inch – he has said: “We have a very firm policy, never breached, to never cooperate with government censorship in any region of the world.”

Physicians are now more likely employed than in private practice, and AMA membership has correspondingly declined

 Medpage Today has the story:

Medical Societies Are Facing an Existential Crisis
— It's time to adapt to the employed physician era

by Hemant Kalia MD, MPH, Mark Adams, MD, MBA, and David Jakubowicz, MD 

 

"According to the American Medical Association (AMA), 2020 marked the first time that fewer than half (49.1%) of physicians worked in doctor-owned practices since their tracking began. By 2022, that number had fallen further to 46.7%, down from 60% a decade earlier. Meanwhile, the share of physicians employed by hospitals and health systems has expanded sharply -- from about 29% of physicians in 2012 to more than 40% in 2022. Private equity ownership, virtually absent in previous decades, now accounts for roughly 5% of physician employment. 

...

" this employment transformation has disrupted the very institutions meant to represent physicians. Nationally, AMA membership has plunged from about 75% of U.S. physicians in the 1950s to just 15% today. State and county medical societies mirror this pattern, facing shrinking memberships, aging leadership, and limited engagement among younger doctors.

"Specialty societies have filled much of that vacuum. Groups like the American College of Physicians, the American College of Surgeons, and the American Academy of Family Physicians have seen significant growth over the past few decades.

The Union of Concerned Scientists celebrates the NSF

 The Union of Concerned Scientists reminds us of some of many things government support of science has contributed to:

What Do Duolingo, The Magic School Bus, and James Bond Have in Common? The US National Science Foundation 

"Its story begins with President Franklin D. Roosevelt, who during World War II recognized the decisive role that scientific research played in national success. As the war ended, Roosevelt envisioned a way to carry that same scientific energy into peacetime; to support knowledge not just for defense, but for discovery. This vision became law under President Harry S. Truman in 1950 with the National Science Foundation Act , establishing a federal agency devoted to “promoting the progress of science” and “advancing the national health, prosperity, and welfare.” 

"Today, NSF accounts for only 0.1% of federal spending but supports roughly a quarter of all federally funded basic research at US colleges and universities. And that research underpins many of the everyday technologies we rely on. 

"75 Years of benefits for the American public 
Ever watch The Magic School Bus or Bill Nye the Science Guy? Those Millennial science classics were funded by NSF. When your local meteorologist points to a Doppler radar image tracking storms or hurricanes, that technology too has NSF roots. If you’ve ever undergone an MRI scan, used American Sign Language (ASL) resources, or benefited from a kidney exchange program, NSF funding helped make those possible."

Nikhil Agarwal Wins Infosys Prize 2025

 From Inomics:

Nikhil Agarwal (MIT) Wins Infosys Prize 2025 for Groundbreaking Work in Market Design 

Recognising innovation in the field of economics, the Infosys Science Foundation (ISF) has awarded the prestigious Infosys Prize 2025 in Economics to Nikhil Agarwal, the Paul A. Samuelson Professor of Economics at the Massachusetts Institute of Technology. 

Nikhil Agarwal's pioneering contributions to market design have set new standards in empirical studies for allocation mechanisms, affecting critical areas such as school choice, medical residency, and kidney exchanges, and make him a worthy winner of the 2025 Infosys Prize in Economics.

The selection of Agarwal comes as part of the ISF's initiative to promote early-career researchers by honoring individuals under 40 years of age. This shift, introduced in 2024, underscores the foundation's commitment to recognizing and nurturing talent that shapes the future of scholarship and innovation. 

Agarwal's research addresses complex "matching problems," scenarios where traditional market principles fall short. His work elucidates how individuals seeking vital resources—like patients in need of kidney transplants or students aiming for college admission—can be systematically matched through innovative market design techniques. By anchoring his theories in empirical data, Agarwal provides profound insights that have the potential to influence policy design and enhance societal welfare. 

The Infosys Prize is renowned for being one of the most significant awards in India, which not only honors excellence but also fosters a scientific culture that drives innovation across multiple disciplines. Each laureate receives a gold medal, a citation, and a prize purse of USD 100,000, along with international recognition, often leading to further prestigious awards.

Are transplants too scarce, or not scarce enough? A surprising debate about India

 India, now the most populous country in the world, does the third highest number of kidney transplants in the world (although their rate of transplantation per million population is quite low).  So transplants are nevertheless very scarce in India compared to the need, which is the situation worldwide.

Earlier this year, however, a paper by three veteran (non-Indian) transplant professionals who have headed large organizations expressed repugnance for the volume of transplants in India, and the fact that it depends mostly on living donor transplantation (LDT), suggesting it can be viewed as "both alarming and reprehensible."  Their paper's title makes it clear how they view it. 

Domínguez-Gil, Beatriz, Francis L. Delmonico, and Jeremy R. Chapman. "Organ transplantation in India: NOT for the common good." Transplantation 109, no. 2, February, 2025: 240-242. 

"The field of organ transplantation has evolved very differently across the world under the influence of different national healthcare financing systems. Healthcare is, in most countries, financed by taxation and thus through governmental budgets, in combination with private funds, mostly through contributory health insurance systems (eg, Australia, Canada, Europe, New Zealand, South America, and the United States). But across much of Asia, tertiary healthcare services, such as transplantation, are almost entirely dependent on the private finances of individuals. The impressive growth in Indian organ transplantation has been accomplished in for-profit hospitals, which have expanded Indian transplantation into 807 facilities, mostly associated with the major corporate hospital chains.6 Organ transplantation, in a part of the world where one-fifth of all people live, is thus largely not for the common good, but a treatment available for those with ample monetary resources." 

########## 

 This was followed by a firm rebuttal by distinguished Indian transplant professionals.  Their title makes their view equally clear:

Rela, Mohamed, Ashwin Rammohan, Vivek Kute, Manish R. Balwani, and Arpita Ray Chaudhury. "Organ Transplantation in India: INDEED, for the Common Good!." Transplantation 109, no. 6 (2025): e340-e342. 

 "We were deeply concerned by the article “Organ Transplantation in India: NOT for the Common Good” by Domínguez-Gil et al,  which we felt provided an unfairly critical view of the current state of organ transplantation in India. We aim to provide a point-by-point rebuttal based on actual figures and ground-reality rather than tabloid-press articles as cited by the authors.
 

"It is true that in the past 5 y, there has been an extraordinary growth in the number of transplantations in India (more than those achieved over several decades by European countries). While it is natural to be wary of this astronomical increase in transplant numbers, the authors’ assumption that this growth is likely nefarious reflects an outdated western mindset, rather than a true understanding of over 2 decades of massively coordinated effort by the Government of India, transplant professionals and all other stakeholders in the country. 

...

" The development of LDT has been presented with a negative connotation. This shows a scant understanding of the geo-socio-political idiosyncrasies prevalent in the Asian region, and unlike the west, its conventional dependence on LDT.

 ...

"The authors have further confused LDT and deceased donor transplantation with regards to foreigners having access to organs in India. The authors’ accusation of deceased donor organs being preferentially allocated to foreigner is presumptuous at best. The current organ allocation system under the aegis of the Government of India and state-wise organ transplant governing bodies is a very transparent process—and is reserved for Indian nationals.

...

" Transplant tourism being equated with organ commerce is erroneous, the authors’ fail to understand that many poor countries find India a more financially viable destination to get a transplant than countries in the west. Even affordable Governments in the middle east are moving to the east for transplantation, where the ministries have a direct tie-up with transplant units. 

"While it should be conceded that transplantation in India may not be available to all, true social upliftment necessitates broader initiatives beyond just immediate transplant availability: that of addressing poverty. Nonetheless, access to transplants for the underprivileged has greatly improved over the past decade. There are several public sector hospitals in the country that routinely provide transplantation services. In 2023, in the state of Tamil Nadu, 35.1% of all deceased donor renal transplants were performed for free in public sector hospitals (Table 1). 5 While traditionally, the private pay-from-pocket healthcare has been only for those with the resources, the central and several state governments (Tamil Nadu, Andhra Pradesh, Gujarat, etc) sponsor an all-inclusive healthcare state insurance for the poor, which includes transplantation at any approved private hospital in the state; which includes LDT.

####### 

I'm on my way to a conference in Cairo that is motivated in part by concern that healthcare in low and middle income countries has been impeded by some of the international healthcare organizations' lack of understanding or empathy for their situations.

School choice and performance gaps in England: a report by Burgess, Cantillon, Greaves and Cavallo

 Estelle Cantillon writes to tell me about her new report with Simon Burgess, Ellen Greaves, and  Mariagrazia Cavallo  on changing the priority criteria in secondary school admissions in England.

"Our starting point was the equity of access to effective schools in England and the role of priority criteria in this regard. England is special in that secondary schools can choose their own priority criteria (within guidelines). Many schools choose geographical criteria or tie-breaking rules, and we show that this is reducing the set of effective schools that disadvantaged pupils have access to. We explore three potential policy reforms: a quota for free-school-meal (FSM) pupils, a lottery for a quota of seats and banding. We find that the FSM quota is not only more effective at increasing access for disadvantaged but does so with less disruption (distance travelled, change in school intakes). Another special feature of our study is that our policy simulations cover all 150+ school districts (called Local Authorities) in England. So no need to worry about: would the effect you find in city X also apply in city Y.  
 
The full report is here: Modifying school choice for more equitable access in England

 Here's a blog post:  Access to highly effective schools: The case for reform
Posted on November 6, 2025 by Ffion Lindsay 

 "How do we address the gap in attainment between the most advantaged and disadvantaged students in the UK? Pioneering research, led by the University of Bristol, reveals the reforms most likely to equalise our education system.
Lead author Simon Burgess, Professor of Economics, explains how the team’s findings could lead to much-needed changes in how school places are allocated.

"There is much to applaud about the school system in England, but also deep problems. Chief among these is the wide and persistent gap in educational attainment between disadvantaged children and pupils from more affluent families.

"For example, in 2019, around 30% of pupils eligible for Free School Meals (FSM) achieved the benchmark performance in GCSEs, compared to double that among more affluent pupils. This gap has barely changed for at least 20 years.

"Part of this gap arises from differences in the effectiveness of the schools these children attend. Richer pupils are much more likely to be assigned to effective secondary schools.

"In fact, richer pupils are over 40% more likely to attend a highly effective secondary school (in the top 25% of value-added, in England called Progress 8). Not only might this be considered unfair for the current generation, it can also perpetuate income inequality through the generations.

 "The geography problem
Differences in the effectiveness of schools attended might simply be the result of families’ preferences for schools. Our research, however, shows that admissions arrangements play an important role in explaining the observed unequal attendance at effective secondary schools.

"Specifically, most English secondary schools explicitly prioritise pupils according to where they live – either through defined catchment areas or by ranking applicants by straight-line distance between home and school.

"This is not neutral: desirable schools generate substantial house price premiums in their catchment areas, effectively pricing out lower-income families. School choice through residential location appears not to be an option for poorer families. We show that richer pupils disproportionately move into the catchment areas of popular schools during their primary school years."

########

Reading this from the U.S., I'm struck by how our problem of sending poor children to poor schools is similar across the pond.  In the US we often attribute this in part to the fact that US schools are funded by municipal  real estate taxes, so schools in richer towns are better funded. But it appears that this problem can be reproduced in England simply by admitting students preferentially based on their nearness to schools, when better schools are located near more expensive houses. (This happens in US cities, too.) The between-country comparisons might help to disentangle peer effects from funding effects in what leads to school effectiveness.

Xenotransplants go to (clinical) trial

 Yesterday's post was about a man who received a pig kidney as an exceptional "compassionate use" case. But now some formal clinical trials of xenotransplantation are beginning. 

 Medpage Today has the story:

First Clinical Trial of Pig Kidney Transplants Gets Underway
— Study's initial transplant was performed successfully

by Associated Press, November 4, 2025  

"The first clinical trial is getting underway to see if transplanting pig kidneys into people might really save lives.

"United Therapeutics, a producer of gene-edited pig kidneys, announced Monday that the study's initial transplant was performed successfully at NYU Langone Health in New York City.

"It's the latest step in the quest for animal-to-human transplants. A second U.S. company, eGenesis, is preparing to begin its own pig kidney clinical trial in the coming months. These are the first known clinical trials of what is called xenotransplantation in the world. 

...

"Robert Montgomery, MD, PhD, of NYU, who led the transplant team, told the Associated Press his hospital has a list of other patients interested in joining the small trial, which will initially include six people. If all goes well, it could be expanded to up to 50 as additional transplant centers join.

"The FDA is allowing the rigorous studies after a series of so-called "compassionate use" experiments, with mixed results. The first two gene-edited pig kidney transplants were short-lived.

"Then doctors began working with patients who badly needed a kidney but weren't as sick as prior recipients. At NYU, an Alabama woman's pig kidney lasted 130 days before she had to return to dialysis. The latest record, 271 days, was set by a New Hampshire man transplanted at Massachusetts General Hospital (MGH) in Boston; he also is back on dialysis after the pig organ began declining and was removed last month. Others known to be living with a pig kidney are another MGH patient and a woman in China. "

Xenotransplant of a pig kidney lasted nine months before failing (a new record)

 No xenotransplant has lasted a year yet, but that's a target that now seems to be within reach for kidneys. (Kidneys are a more forgiving test of xenotransplants than, say, hearts, since after graft failure the patient can remain alive on dialysis once again.)

The NYT has the story:

Pig Kidney Removed From Transplant Patient After Nine Months
Tim Andrews, 67, lived with a genetically modified organ longer than any other recipient. 
By Emily Anthes

"Surgeons removed a genetically modified pig kidney from a 67-year-old man last week, nearly nine months after he received the pioneering procedure at Massachusetts General Hospital in Boston, officials said on Monday. The kidney was removed “after a period of decreasing kidney function,” according to a statement from the hospital.

"The patient, Tim Andrews, lived with the pig kidney for a record-setting 271 days. He was the fourth person in the United States to receive a genetically modified pig kidney. The first two patients died shortly after their transplants; the third had her kidney removed after 130 days, when her body rejected the organ.

“Tim set a new bar in xenotransplantation,” the Mass General Brigham statement said, referring to the process of transplanting organs from one species into another.

"Mr. Andrews “will now resume dialysis and remain on the list for a human donor kidney,” the hospital added
."

Surrogacy, and escrow accounts

 Surrogacy contracts involve a long term relationship, focused on a nine month pregnancy.  So commercial surrogacy depends on secure financial arrangements, which generally require funds to be held in escrow.  The WSJ article below documents that these escrow accounts are insufficiently regulated in some states, which can cause serious problems for surrogates and intended parents when the account holders are dishonest or careless.

Surrogacy Is a Multibillion-Dollar Business. Sometimes the Money Goes Missing.  "The growing industry has little regulation and many cases of financial abuse; escrow funds taken to pay gambling debts, buy bitcoin." By Ben Foldy
 

"Escrow companies, used in the majority of surrogacies, can handle millions of client dollars with almost no oversight, according to a Wall Street Journal review of court filings and interviews with parents and surrogates.

...

"The lack of regulation means that parents and surrogates frequently have little legal recourse and dim hopes of recovering lost funds. Already-pregnant surrogates must carry through with labor that they know they may not be paid for, while potentially being on the hook for medical bills they may not be able to afford. Parents face the prospect of messy litigation from unpaid surrogates. One couple whose surrogacy funds disappeared due to fraud before they were able to successfully transfer an embryo said they gave up hope for a pregnancy.

“Holding other people’s money is usually such a highly regulated industry,” said Andrew Bluebond, an attorney in Texas who helped Gallozzi look into what happened at SEAM. The surrogacy community’s relatively small size and intimate domain, Bluebond said, fostered a false sense of financial security.

“Rather than using the safeguards other industries use, they let their trust betray them,” he said. 

...

"Surrogacy has exploded into a multibillion-dollar industry, driven by increasing rates of infertility, expanded insurance coverage, the growing prevalence of LGBTQ families and an influx of couples from countries where the practice is illegal, including China. Last week, President Trump announced a deal aimed at lowering the price of medications used in IVF. 

There were around 10,850 transfers of embryos to surrogates in the U.S. in 2023 involving clinics reporting to the Society for Assisted Reproductive Technology, which says it represents clinics that perform around 95% of all procedures. That was up from 8,461 in 2021. The group’s data and other analyses expect an annual growth rate of about 15% over the coming years. About half of those embryo transfers resulted in successful deliveries.

Despite the growth, there are no federal laws regulating the financial or other aspects of surrogate pregnancies, and the practice is subject to a patchwork of state regulations. In Louisiana, for example, compensating surrogates is outlawed entirely. In a handful of other states, the contracts that often accompany surrogacy arrangements are legally unenforceable. 

...

"Last month, the nonprofit Society for Ethics in Egg Donation and Surrogacy, which functions as a kind of industry best-practices group in lieu of regulation, passed new guidelines for escrow accounts, although they have no binding power. The suggestions recommend escrow providers have relevant credentials, are subject to audits by certified accountants and have more than $10 million in bond coverage. "

Experimental economics at the University of Pittsburgh

 I recently had the opportunity to visit my old haunts at the University of Pittsburgh, and took part in a reopening and re-dedication of the famous experimental economics lab there. Here's the announcement:

 PEEL is officially back open after renovations

The Pittsburgh Experimental Economics Laboratory (PEEL) celebrated its grand reopening last week following substantial renovation. Led by PEEL Director Lise Vesterlund, the renovations allow Pitt to continue to lead as one of the preeminent experimental economics research universities in the country.

Alvin Roth, winner of the 2012 Nobel Memorial Prize in Economics, was on site to celebrate the event. Roth, who was the Andrew W. Mellon Professor of Economics at Pitt through the 1980s and 90s and is now a professor at Stanford University, founded the lab in 1988 alongside then-Pitt Professor John Kagel.  His original research at PEEL led to his Nobel Prize for market design and to his design of the National Residency Matching Program (NRMP) and the New England Program for Kidney Exchange.  

“Experiments are very powerful, and I think this [lab] is a huge advantage,” Roth said. “For a long time, economists thought of data as something that governments collected […] but when you do experiments, you can carefully control for what you think are relevant differences and understand causes much better.” 

 

 Vesterlund, who has held the Mellon chair in economics since 2007, has conducted countless experiments in the lab. Particularly influential has been her research assessing the impact of work assignment on gender differences in advancement, research that lead to her award-winning co-authored book The No Club: Putting a Stop to Women's Dead-End Work.  

Vesterlund says a well-functioning lab is the foundation for Pitt’s strong economics department. “PEEL is a world-renowned experimental economics laboratory.  It has been the home to countless seminal research findings. Findings that seeded fields in the profession and improved the way we design markets and organizations. Few institutions can maintain a well-functioning lab, and PEEL has been essential in drawing an exceptionally strong group of scholars to Pitt. The renovation will ensure that the University of Pittsburgh continues to be the center for cutting-edge research in experimental economics.” 

The ceremony included opening remarks from Dean Adam Leibovich before Vesterlund and Roth cut the ribbon, formally re-opening the lab. The renovated lab comprises 40 computer kiosks, where participants can engage with state-of-the-art research software and make choices that inform us about human decision-making.
