Fentanyl

 The NY Times has the story:

Some Key Facts About Fentanyl. It’s lowering American life expectancy and influencing the nation’s politics. By Josh Katz, Margot Sanger-Katz and Eileen Sullivan

"Overdose deaths have been increasing in the United States for decades, but the introduction of fentanyls has led to a staggering rise, accounting for the vast majority of overdose deaths in recent years.


"Around 77,000 Americans died from overdoses involving synthetic opioids like fentanyl in the 12-month period ending in April of this year, according to provisional estimates from the Centers for Disease Control and Prevention. In 2022, the most recent year with complete data, this number was around 74,000. Those three wars  [Vietnam, Iraq and Afghanistan] killed a little over 65,000 Americans combined.

"For comparison, around 55,000 Americans died in 1972 from car crashes, the year with the most such deaths. Around 49,000 died from guns in 2021 (including suicide), the year with the most such deaths.

"Fentanyl alone has become a leading cause of U.S. deaths. It was responsible for a third of deaths among Americans 25 to 34 in 2022, according to a New York Times analysis of C.D.C. mortality data.

...

"Most of the fentanyl sold in the United States is coming from Mexico, where drug cartels synthesize the drugs from precursor chemicals believed to come from factories in China. Some fentanyls are also shipped directly from China into the United States."

Thinking locally about Hamas, and murderous antisemitism, on college campuses

 How should universities deal with controversy in the midst of horrors?

Both Harvard and Stanford are having troubles with talking about Israel and Hamas.  Below are two news articles, and a letter...

Here's the NY Times, on Harvard:

At Harvard, a Battle Over What Should Be Said About the Hamas Attacks. After a student group blamed Israel for the violence, Lawrence Summers, a former university president, condemned the leadership for not speaking up.  By Anemona Hartocollis, Stephanie Saul and Vimal Patel

#######

And here's the SF Chronicle on Stanford and Berkeley:

Stanford, UC Berkeley respond to Israel-Hamas war amid campus debates by Nanette Asimov

"Rather than condemn the brutal invasion by Hamas into Israel, some student groups at universities across the country are turning the message around, using posters, social media posts and statements in campus newspapers to criticize Israel for its historic hard line against Palestinians.

"And some prominent universities have let them.

"On Wednesday, dozens of faculty members, including three Nobel laureates, sent a letter to Stanford leaders condemning the university’s mild response to the crisis and to pro-invasion sentiments expressed on campus.

"The letter to interim President Richard Saller and Provost Jenny Martinez chastised Stanford not only for referring to the murder of at least 1,200 Israelis and more than 100 people taken hostage merely as the “Middle East conflict,” but also for failing to remove “extremely offensive banners” on campus calling for the abolition of Israel, and for standing by as Jewish students were targeted online after the invasion by Hamas.

“This situation calls for a clear condemnation of terrorism and a strong stance in support of basic human rights and dignity,” says the letter signed by faculty across many disciplines and by three Nobelists: Michael Levitt, who won for chemistry, and the economists Paul Milgrom and Alvin Roth.

##########

Here's the Stanford letter:

Dear President Saller and Provost Martinez,

 We, members of the Stanford community — faculty, staff, students, and alumni — feel the obligation to share our thoughts on the university's response to the recent events in Israel and Gaza. 

 Many members of the Israeli and Jewish communities on campus are experiencing the hardest, most stressful days of their lifetime. Many Stanford faculty members and students have been reaching out to their Jewish and Israeli friends and colleagues, to extend their sympathy and support. These past few days have been terrifying and incredibly painful for us all, and this acknowledgment is heartwarming and greatly appreciated.

 With that said, we must respectfully convey our concerns regarding the wording used in the messages sent by Stanford University as an institution, which, unintentionally, downplays the horrific gravity of the situation. Furthermore, over the last few days extremely offensive banners, calling to abolish Israel “by all means necessary”, have been on display in various spots on campus. Jewish, Israeli, and Zionist students at Stanford are being targeted both on campus and on Stanford-affiliated platforms. We are aware of some messages published by various University officials. However, the University has yet to take appropriate action against what is happening. 

 Since Saturday morning, Hamas has murdered more than 1,200 Israelis, many of them women, children, and elderly Holocaust survivors, in their homes and on the streets. Over one hundred more have been brutally kidnapped and taken hostage. These include young women paraded naked through the streets, toddlers ruthlessly snatched away from their parents, and elderly people in wheelchairs. The murdered and kidnapped are not just Israelis, they are also citizens of the United States, Brazil, Argentina, Nepal, Thailand, and Germany. These are not a result of “the Middle East conflict”, as stated in the University's message from earlier today. Rather, it is the result of a horrific, inhumane, terror attack by Hamas that has shaken the international and Jewish communities in a way we have not experienced since the darkest days of the previous century.

 While there may be an instinct to chalk this up to just another skirmish in the Israel-Palestinian conflict, it is imperative that all of us are able to understand the gravity of these acts and call out terrorism. Phrasing these acts as “the Middle East conflict” inadvertently suggests a moral equivalence between the actions of terrorists and of those trying to protect innocent lives.

 We believe that in an academic institution like Stanford, where critical thinking and accurate representation of events are paramount, it is essential to be mindful of the language we use. This situation calls for a clear condemnation of terrorism and a strong stance in support of basic human rights and dignity. Let us be clear, we are not demanding support of the Israeli government's policies vis a vis Gaza or the occupation, and in fact, many of us are ardent activists against these policies. Rather, as a bastion of critical and nuanced thinking, Stanford should be able to hold any and all of these positions while also unequivocally calling out unequivocal evil, as President Biden did earlier today. The Israel-Palestine conflict is complex and nuanced. Condemnation of the murder, rape, and kidnapping of innocent civilians should not be.

     We believe that Stanford should immediately take action: it must voice its unambiguous condemnation of the horrifying actions taken by Hamas these past days. It must reach out to Israeli and Jewish students on campus and voice a clear message of support in these dire times. The university must act, firmly and immediately, to prevent hate speech, including antisemitic voices on campus, which, unfortunately, has already seen troubling instances of antisemitism in recent years. The university must ensure the safety of our Stanford community, which includes our Jewish and Israeli members. The lack of appropriate response is deeply troubling to us, as faculty, staff, students, and alumni of this university. Stanford’s failure to act appropriately is unacceptable.

 Thank you for your attention to this matter, as well as for reaching out and offering us your support. We hope we can continue to engage in thoughtful dialogue. 

 Sincerely,

*********

The great thing about prizes and other recognitions is that they celebrate the accomplishments of the accomplished.  The complicated thing about them is that they inevitably leave out many whose accomplishments are deserving of similar celebration.

What makes the Econometric Society Fellows such an interesting recognition is that its procedures are transparent: it's a nomination process followed by an election, and the electorate is the collection of existing Fellows.  I participate each year by nominating several Fellows, and then voting for quite a few more. 

One flaw in such a system could be that the existing fellows, who initiate many of the nominations, might find it easier to think of people close to them in some sense than to think of equally deserving candidates who aren't so close.  The Fellows Nominating Committee (FNC) is an attempt to address this: their job includes nominating deserving candidates  who seem likely to have been overlooked, perhaps because they are from parts of the world that seem underrepresented among the existing Fellows.

Each year the number of nominees is a multiple of the number of elected Fellows (if memory serves only around a fifth of the nominees have been elected in recent years). The rules of the election since 2020 are that the threshold to get elected is to be included in 25% of the votes cast (and a single "vote"  if I understand correctly is a list submitted by a Fellow that can contain as many of the nominated candidates as he or she wishes to vote for).  I say "since 2020" because it is the sense of many of the past and present officers of the Society that we elect too few Fellows each year, and so the threshold has been dropping in an effort to elect more fellows.  But the equilibrium response of the voters seems to be to vote for a smaller proportion of the nominees, so that the number of new fellows doesn't seem to be increasing at the hoped for rate.

I don't know of a good model to explain all this, but it might  include some notion that the value of being a Fellow (or of receiving other recognition) is a non-monotone function of its scarcity.  If we elect too many new Fellows, this might eventually diminish the value (to existing Fellows) of being a Fellow.  But (less obviously), if we elect too few Fellows the same thing could happen, if being a Fellow stops being something that people aspire to or even have heard of.  

My sense is that being a member of the National Academies is less important among economists than in many sciences precisely because too few economists are elected, so that it comes to seem like a random recognition rather than one that recognizes success as economists define it. One of the reasons that the economics Nobel, awarded yesterday with much fanfare to Claudia Goldin, is so widely applauded, not just in the disciplines in which Nobels are awarded but among the general public as well,  is that Nobels are awarded every year in several disciplines, so that they manage to be both a scarce distinction and a familiar one. (Exceptions that test this rule are the Clark medal, awarded each year by the American Economic Association to an economist younger than 40, which has high prestige among American economists even though so few are well recognized enough at that age to be serious contenders, and the Fields medals of the International Mathematical Union, also awarded to up to four scholars under 40, every four years.)

But nothing is perfect. Congratulations again to the new Fellows, who have received the carefully considered and frugally awarded applause of their peers.

Claudia Goldin wins the 2023 Nobel Prize in Economics

 The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel 2023 was awarded  today to the indefatigable

Claudia Goldin "for having advanced our understanding of women’s labour market outcomes"

Here's her latest NBER working paper, which appeared yesterday:

Why Women Won

Claudia Goldin

WORKING PAPER 31762, DOI 10.3386/w31762, October 2023

Abstract: How, when, and why did women in the US obtain legal rights equal to men’s regarding the workplace, marriage, family, Social Security, criminal justice, credit markets, and other parts of the economy and society, decades after they gained the right to vote? The story begins with the civil rights movement and the somewhat fortuitous nature of the early and key women’s rights legislation. The women’s movement formed and pressed for further rights. Of the 155 critical moments in women’s rights history I’ve compiled from 1905 to 2023, 45% occurred between 1963 and 1973. The greatly increased employment of women, the formation of women’s rights associations, the belief that women’s votes mattered, and the unstinting efforts of various members of Congress were behind the advances. But women soon became splintered by marital status, employment, region, and religion far more than men. A substantial group of women emerged in the 1970s to oppose various rights for women, just as they did during the suffrage movement. They remain a potent force today.

 Here's the concluding paragraph:

"Women won some of their most important workplace rights in the 1960s because of a set of fortuitous events. They continued to win in the early 1970s because of a movement that gave them influence. They won yet more because groups that were supportive of their cause—college graduates, single women, Black women—expanded relative to others. They won when they had the political clout to get men, especially those in Congress and the White House, to see that women’s rights were as valid as civil rights. Yet, women’s rights had setbacks when, in light of many gains, women abandoned the movement. Women’s rights has had a truly “strange career.”

Dead or alive? Debates about defining brain death and circulatory death in the medical literature

Before the invention of ventilator technology, circulatory death ('cardiorespiratory death') and brain death ('neurological death') were essentially the same thing, because one inevitably caused the other, very quickly.  But now that circulation can be maintained after the brain has gone irreversibly/permanently silent, we can make distinctions.  And some of those distinctions depend on the distinction between irreversibly and permanently.  This post starts with a position statement, but then features the underlying debate, and in fact two of the dueling papers take opposite stands on 'irreversible' and 'permanent.'. (The difference is that e.g. heart stoppage might be possibly reversible, but a 'do not resuscitate' order would mean that it was nevertheless permanent.) 

But before the debate, here's a position paper

Standards and Ethics Issues in the Determination of Death: A Position Paper From the American College of Physicians by  DeCamp, Matthew, Kenneth Prager, and American College of Physicians Ethics, Professionalism and Human Rights Committee, Annals of Internal Medicine (2023).

"Abstract: The determination of a patient’s death is of considerable medical and ethical significance. Death is a biological concept with social implications. Acting with honesty, transparency, respect, and integrity is critical to trust in the patient–physician relationship, and the profession, in life and in death. Over time, cases about the determination of death have raised questions that need to be addressed. This American College of Physicians position paper addresses current controversies and supports a clarification to the Uniform Determination of Death Act; maintaining the 2 current independent standards of determining death, cardiorespiratory and neurologic; retaining the whole brain death standard; aligning medical testing with the standards; keeping issues about the determination of death separate from organ transplantation; reaffirming the importance and role of the dead donor rule; and engaging in educational efforts for health professionals, patients, and the public on these issues. Physicians should advocate for policies and practices on the determination of death that are consistent with the profession’s fundamental and timeless commitment to individual patients and the public."

...

"Scientific advances motivate revisiting foundational concepts, including those around death and dying. Decades ago, advanced cardiorespiratory support—because of its ability to maintain cardiac and respiratory functions in individuals whose brain function was thought to have ceased—contributed to the development of brain death as a concept. Studies now show restoration of cellular and molecular activity in whole pig brains (without restoration of brain functions) 4 hours postmortem using an ex vivo perfusion system called “BrainEx” (15, 16). Today, a controversial protocol known as thoracoabdominal normothermic regional perfusion with controlled donation after circulatory determination of death can result in the resuscitation of the asystolic heart to restore circulation after what was a determination of circulatory death—to increase organ availability for transplant—but this invalidates the determination of death and breaches ethical boundaries (17, 18). Moreover, there has been ongoing advancement in ancillary tests, such as electroencephalograms, magnetic resonance angiography, single-photon emission computed tomography, hypothalamic testing (19), computed tomography angiography, computed tomography perfusion (20), and others. Results of these methods of testing can raise questions about the accuracy of clinical determinations of death.

...

"Position 1

ACP supports revising the Uniform Determination of Death Act (UDDA) to replace the word “irreversible” with “permanent” in the first clause to read, “An individual who has sustained either (1) permanent cessation of circulatory and respiratory functions, or (2) irreversible cessation of all functions of the entire brain, including the brain stem, is dead. A determination of death must be made in accordance with accepted medical standards.”


"The UDDA (21) currently states, “An individual who has sustained either (1) irreversible cessation of circulatory and respiratory functions, or (2) irreversible cessation of all functions of the entire brain, including the brain stem, is dead. A determination of death must be made in accordance with accepted medical standards.”

Nicotine in New Zealand, banned for the future generation.

 In New Zealand, the incidence of smoking is down, but not so much among the Maori. And now there's a law that cuts nicotine content of cigarettes, and (get this) "bans the next generation of New Zealanders — anyone born after 2008 or currently 14 years old or younger — from ever buying cigarettes in the country. " (That's going to be a complicated age restriction to administer in, say, 10 years from now...)

NPR has the story:

It's one of the world's toughest anti-smoking laws. The Māori see a major flaw  by Simar Bajaj

"In 2011, New Zealand set one of the most audacious public health targets in the world: to slash its cigarette smoking rate to 5% by 2025.

"The rate was 18% at the time. Fast forwarding over a decade later, the country seems on track to reach this goal ahead of the 2025 target — but only for its European and Asian populations. Māori, on the other hand, had the country's highest smoking rate at 20% in 2021, and they are expected to reach the 5% goal only 40 years later in 2061 per government modeling.

...

"Every year, 4,000 Māori die in New Zealand, and cigarettes are responsible for nearly a quarter of these deaths, according to an estimate in The New Zealand Medical Journal. The study also found that smoking explains a third of the seven-year life expectancy gap between Māori and other New Zealanders.

...

"Last December, in an all-hands-on-deck effort to get Māori across the 2025 finish line, New Zealand passed one of the strongest anti-tobacco laws in global history.

"Specifically, the legislation limits the amount of nicotine in cigarettes to non-addictive levels and reduces the number of retailers allowed to sell cigarettes from 600 currently to 60 by July 2024.

"Most remarkably, the law bans the next generation of New Zealanders — anyone born after 2008 or currently 14 years old or younger — from ever buying cigarettes in the country. "The denicotinization and retail reduction are important for us to get to the lower than 5% smoking rate," says New Zealand's Health Minister Ayesha Verrall, "and then the smoke-free generation policy is to keep us there."

...

"Fears that the crackdown on smoking will backfire

"Tobacco regulation is like a game of whack-a-mole: Knock a product out of one market, and it'll usually pop up in another possibly illegal transaction. In 2019, illicit tobacco represented almost 12% of New Zealand's consumption, and this new legislation may further relegate tobacco to the black market, according to Māori physician and Parliament member Shane Reti, who has tribal affiliations to Ngā Puhi, Ngāti Wai, Ngāti Hine and Ngāti Kura. What he's particularly concerned about is that, given high rates of tobacco addiction in his community, this expanded black market will disproportionately impact Māori via more dangerous cigarettes and police crackdowns.

...

"The risk of such smuggled tobacco, Reti points out, is that it would exist wholly outside New Zealand's safety regulations. As such, he posits that these cigarettes would be more addictive and toxic for Māori who continue to smoke, with higher levels of nicotine and heavy metals like lead. (It is presently illegal to import tobacco into New Zealand without a permit.)

"On the supplier side, organized crime syndicates, which are responsible for large-scale cigarette smuggling, may also surge. "We have some of the highest cost of living and the highest inflation we've had in decades in New Zealand," Reti says, "and what we know is that vulnerable groups who are desperate turn to crime." Given New Zealand's incarceration rates — over half of prisoners are Māori despite representing only 17% of the country — Reti worries that an invigorated black market will lead to a disproportionate crackdown in his community and an even higher percentage of Māori prisoners.

...

"Reti is also concerned about the economic impact on New Zealand's dairies because the anti-tobacco legislation reduces the number allowed to sell cigarettes by 90%. (Dairy is the term New Zealanders use for neighborhood convenience stores.) That might be problematic because tobacco makes up a substantial proportion of dairies' revenue, with estimates ranging from 14% to 47%. If dairies can't find other ways to increase sales, this policy "will almost decimate the small retailers, those small corner dairies," says Reti.

...

"But just as he isn't concerned about the black market, Waa thinks these economic arguments are similarly overblown. "This is my conspiracy hat on, but we suspect that a lot of these arguments are put up by the tobacco industry" to keep their product in stores. Waa points to how dairy owners submitted some 1,000 complaints to the government, all of them following a single template. In any case, Waa has little sympathy for retailers insisting on selling tobacco "because they're making money out of my people dying."

Correcting science faster by making replication easier and more fun, by Brodeur, Dreber, Hoces de la Guardia & Miguel

If imitation is the sincerest form of flattery, we need to think of replication as one of the sincerest forms of inquiry in social science. (I'm more optimistic about the potential role of replication than I am about pre-registration.)

Here's a Comment in Nature that points out that we're not going to get lots of replications unless we can make them easier and more fun than they have been traditionally.

Replication games: how to make reproducibility research more systematic.  In some areas of social science, around half of studies can’t be replicated. A new test-fast, fail-fast initiative aims to show what research is hot — and what’s not.  by Abel Brodeur, Anna Dreber, Fernando Hoces de la Guardia & Edward Miguel

"we decided to try to make replication efforts in our fields of economics and political science more systematic. Our virtual, non-profit organization, the Institute for Replication, now holds one-day workshops — called replication games — to validate studies.

"Since October 2022, we’ve hosted 12 workshops across Europe, North America and Australia, with 3 more scheduled this year. Each workshop has typically involved around 65 researchers in teams of 3–5 people, re-analysing about 15 papers. The teams either try to replicate papers, by generating new data and testing hypotheses afresh, or attempt to reproduce them, by testing whether the results hold if the published data are re-analysed. For many papers in our fields of study, in which the reproduction of results often involves re-running computer codes, it’s possible to do much of this work in a single day (see ‘A typical replication games project’). Each team’s findings are released as a preprint report, and these reports will be collated and published each year as a meta-paper. 

...

"To assess large numbers of papers, collaborating with research centres and universities is essential. For example, our current goal is to reproduce and replicate studies in journals that have a high impact factor — specifically, 25% of empirical studies published from 2022 onwards in 8 leading economics journals and 3 leading political science journals, totalling about 350 papers per year. Then we plan to expand into other areas of the social sciences.

...

"Broader partnerships can expand replication efforts beyond academic papers. Earlier this year, we were invited to run replication games with the International Monetary Fund (IMF) and the World Bank, to assess economics and finance papers from the two organizations. We aim to keep running these games annually, validating not only scholarly studies but also policy-oriented reports.

"Establishing these relationships need not be time consuming. We’ve found that simply tweeting about our project and speaking about it at conferences can garner interest. That, along with word of mouth after the Oslo workshop, has been sufficient to make our project well known among economists. As a result, all the organizations that we partnered with originally contacted us — rather than the other way round — asking to get involved.

"Other researchers following in our footsteps should be aware that care is needed to avoid conflicts of interest. We receive no money from the collaborations we’re involved in, because taking payment could be viewed as unethical. At the IMF and World Bank games — where people were reproducing and replicating the work of co-workers — we decided to randomly assign participants to a study, allowed them to remain anonymous and prevented participants from assessing studies authored by direct supervisors or friends.

"It is crucial to protect researchers who check papers from career threats — particularly when an effort uncovers major errors. We recommend that an organization or institute mediates communication between the original study’s authors and the replicators, allowing the latter to remain anonymous if they wish. One of us, acting as a representative for the Institute for Replication, serves in this capacity after each replication game.

"We know that receiving an e-mail to say that someone is checking your work can be stressful. So we contact the original authors only after replicators have written up their reports, to avoid causing researchers undue worry while they wait for an effort’s results. Rather than treating the discovery of errors as a ‘gotcha’ moment, which can put authors on the defensive, we acknowledge in our correspondence that all researchers make mistakes. To help make the process collegial, we allow authors to suggest edits to the report, and ask replicators to suggest changes to the authors’ responses.

...

"We think that efforts such as ours that normalize replication will ultimately put pressure on funders and journals to play their part. We are excited to see replication efforts in our fields — and others — continue to expand. Systematic replication has the potential to make correcting science faster. Let the games begin."

Pakistan police bust organ trafficking ring --transplants were carried out in private homes

 Outlawing compensation for donors doesn't end black markets for kidneys from living donors, but may succeed in driving them out of hospitals, and making them increasingly dangerous and black.

The BBC has the story:

Pakistan police bust organ trafficking ring that took kidneys from hundreds By Rachel Russell

"Eight members of an organ trafficking ring in north-east Pakistan have been arrested, police say.

"The ring's alleged leader, Fawad Mukhtar, is accused of extracting the kidneys of more than 300 people and transplanting them into rich clients.

...

"At least three people died from having their organs harvested in this way, authorities said.

...

"The transplants were carried out in private homes - often without the patient knowing, the chief minister of Punjab province Mohsin Naqvi said.

"A car mechanic is said to have worked as Mr Mukhtar's surgical assistant and helped lure vulnerable patients from hospitals.

"The kidneys were then sold for up to 10 million rupees (£99,000; $120,000) each, Mr Naqvi added.

...

"The commercial trade of human organs was made illegal in Pakistan in 2010.

"The punishment for those caught includes a decade-long jail term and huge fines in the hope that this will stop sales to overseas clients by exploitative doctors, middlemen, recipients and donors.

"However, there has been a rise in organ trafficking in the country as people struggle with low wages and a poor enforcement of the law."

Immigration, immigration law, and illegal immigrants in legal limbo. Should we have a statute of limitations after which immigrants become legal?

We're seeing so much illegal immigration, maybe we should change some of our laws, at least to regularize the status of immigrants who have successfully built productive lives here.  One suggestion is to have a statute of limitation on the crime of illegal immigration, That could work like common law marriage, after a long enough time, the status quo becomes legal.

The NY Times has the story:

Why Can’t We Stop Unauthorized Immigration? Because It Works. Our broken immigration system is still the best option for many migrants — and U.S. employers. By Marcela Valdes

"The three most recent presidents have tried and failed to fix the problem of mass unauthorized migration into the United States. President Obama tried to balance empathy with enforcement, deferring the deportation of those who arrived as minors and instructing immigration officers to prioritize the arrest of serious criminals, even as he connected every jail in the nation to Immigration and Customs Enforcement (ICE). President Trump emphasized enforcement at all costs: revoking deferred action for minors, declaring the arrest of every undocumented person a priority, separating migrant families and trying to terminate temporary protected status for about 400,000 people — though Trump also extended deferred action to about 200,000 Venezuelans during his last full day in office.

"So far, President Biden has revived the empathy-and-enforcement strategy: resuming deferred action for minors and helping Venezuelans while also making it more difficult to qualify for asylum.

"But these variations in policy have had almost no effect on the number of migrants trying to enter the United States through the Southern border. Obama and Trump chose mostly opposing strategies, but each prioritized the arrest of unauthorized migrants in the Rio Grande Valley. Yet in 2019, before the pandemic gave Trump legal standing to force asylum seekers back into Mexico, Customs and Border Protection (C.B.P.) arrested about 82,000 more migrants there than they had at the peak of migrations in the Obama years.

...

"Until the 1920s, America received migrants with an almost open border. Our policies emphasized regulation, not restriction. A few general categories were barred from entry — polygamists and convicted criminals, for example — but almost everyone else was permitted to enter the United States and reside indefinitely. The move toward restriction began in 1882 with laws that targeted the Chinese then evolved to exclude almost every other national group as well.

"Legal immigration today is close to impossible for most people. David J. Bier of the Cato Institute recently estimated that around 3 percent of the people who tried to move permanently to the United States were able to do so legally. “Legal immigration is less like waiting in line and more like winning the lottery: It happens, but it is so rare that it is irrational to expect it in any individual case,” he wrote in a comprehensive review of the current regulations. He concludes that “trying the legal immigration system as an alternative to immigrating illegally is like playing Powerball as an alternative to saving for retirement.”

"In other words, illegal immigration is the natural consequence of the conflict between America’s thirst for foreign labor and its strict immigration laws. The world’s increasing connectedness and fluidity have just supercharged this dynamic. There are now more than 11 million undocumented immigrants inside the United States, three times the number that lived here in 1990. And during the last fiscal year, the number of C.B.P. arrests in the Rio Grande Valley hit a record: more than half a million.

...

"Among academics, another idea keeps resurfacing: a deadline for deportations. Most crimes in America have a statute of limitations, Mae Ngai, a professor of history at Columbia University, noted in an opinion column for The Washington Post.  The statute of limitations for noncapital terrorism offenses, for example, is eight years. Before the 1924 Immigration Act, Ngai wrote in her book about the history of immigration policy, the statute of limitations for deportations was at most five years. Returning to this general principle, at least for migrants who have no significant criminal record, would allow ICE officers and immigration judges to focus on the recent influx of unauthorized migrants. A deadline could also improve labor conditions for all Americans because, as Ngai wrote, “it would go a long way toward stemming the accretion of a caste population that is easily exploitable and lives forever outside the polity.”

Matching Mechanisms for Refugee Resettlement By Delacrétaz, Kominers, and Teytelboym

Learning how better to resettle refugees is not going to go out of style anytime soon.  Here's a recent AER paper:

Matching Mechanisms for Refugee Resettlement By David Delacrétaz, Scott Duke Kominers, and Alexander Teytelboym, American Economic Review 2023, 113(10): 2689–2717 https://doi.org/10.1257/aer.20210096

Abstract: "Current refugee resettlement processes account for neither the preferences of refugees nor the priorities of hosting communities. We introduce a new framework for matching with multidimensional knapsack constraints that captures the (possibly multidimensional) sizes of refugee families and the capacities of communities. We propose four refugee resettlement mechanisms and two solution concepts that can be used in refugee resettlement matching under various institutional and informational constraints. Our theoretical results and simulations using refugee resettlement data suggest that preference-based  matching mechanisms can improve match efficiency, respect priorities of communities, and incentivize refugees to report where they would prefer to settle."

The growing role of kidney exchange in the U.S.

 Here's a paper accepted for publication in the American Journal of Transplantation, tracing the growing role of kidney exchange in the U.S. (But much remains to be done...)

Temporal Trends in Kidney Paired Donation in the United States: 2006 – 2021 UNOS/OPTN Database Analysis  by Neetika Garg, MD, Carrie Thiessen, MD, PhD, Peter P. Reese, MD, PhD, Matthew Cooper, MD, Ruthanne Leishman, RN, MPH, John Friedewald, MD, Asif A. Sharfuddin, MD, Angie G. Nishio Lucar, MD, Darshana M. Dadhania, MD, MS, Vineeta Kumar, MD, Amy D. Waterman, PhD, Didier A. Mandelbrot, MD  PII: S1600-6135(23)00694-9 DOI: https://doi.org/10.1016/j.ajt.2023.09.006 To appear in: American Journal of Transplantation

Abstract:  Kidney paired donation (KPD) is a major innovation that is changing the landscape of kidney transplantation in the United States. We used the 2006 - 2021 United Network for Organ Sharing data to examine trends over time. KPD is increasing, with one in 5 living donor kidney transplants (LDKT) in 2021 facilitated by KPD. The proportion of LDKT performed via KPD was comparable for non-Whites and Whites. An increasing proportion of KPD transplants is going to non-Whites. End-chain recipients are not identified in the database. To what extent these trends reflect how end-chain kidneys are allocated, as opposed to increase in living donation among minorities, remains unclear. Half the LDKT in 2021 in sensitized (PRA ≥80%) and highly sensitized (PRA ≥98%) groups occurred via KPD. Yet, the proportion of KPD transplants performed in sensitized recipients has declined since 2013, likely due to changes in the deceased donor allocation policies and newer KPD strategies such as compatible KPD. In 2021, 40% of the programs reported not performing any KPD transplants. Our study highlights the need for understanding barriers to pursuing and expanding KPD at the center level, and the need for more detailed and accurate data collection at the national level.

Facial recognition software and autocracy

 Here's a somewhat chilling recent NBER paper:

Exporting the Surveillance State via Trade in AI  by Martin Beraja, Andrew Kao, David Y. Yang & Noam Yuchtman  WORKING PAPER 31676   DOI 10.3386/w31676  September 2023

We document three facts about the global diffusion of surveillance AI technology, and in particular, the role played by China. First, China has a comparative advantage in this technology. It is substantially more likely to export surveillance AI than other countries, and particularly so as compared to other frontier technologies. Second, autocracies and weak democracies are more likely to import surveillance AI from China. This bias is not observed in AI imports from the US or in imports of other frontier technologies from China. Third, autocracies and weak democracies are especially more likely to import China’s surveillance AI in years of domestic unrest. Such imports coincide with declines in domestic institutional quality more broadly. To the extent that China may be exporting its surveillance state via trade in AI, this can enhance and beget more autocracies abroad. This possibility challenges the view that economic integration is necessarily associated with the diffusion of liberal institutions.

The EU considers tightening bans on compensating donors of Substances of Human Origin (SoHO)

 Peter Jaworski considers an  EU proposal this month to harmonize across the EU bans on paying donors for Substances of Human Origin (SoHO).  Presently Germany, Austria and Chechia allow payment to plasma donors.

The E.U. Doesn't Want People To Sell Their Plasma, and It Doesn't Care How Many Patients That Hurts. The United States currently supplies about 70 percent of the plasma used to manufacture therapies for the entire world.  by PETER JAWORSKI 

"The European Union looks like it might take the foolish step of banning financial incentives for a variety of substances of human origin, including blood, blood plasma, sperm, and breast milk. The legislation on the safety and quality of Substances of Human Origin includes an approved amendment that says donors can only be compensated for "quantifiable losses" and that such donations are to be "financially neutral." This legislation is supposed to harmonize the rules across the 27 member countries, promote safety, with the ban on financial incentives intended to avoid commodification and the exploitation of the poor. 

...

"Already the E.U. is dependent on plasma collected in the United States for around 40 percent of the needs of its 300,000 rare disease patients. They're not as dependent as Canada because Germany, Austria, Hungary, and the Czech Republic allow a flat-fee donor compensation model and so are able to have surplus collections that contribute 56 percent of the E.U. total. The remaining 23 countries, each of which runs a plasma collection deficit, manage just 44 percent. 

"So what is likely to happen if the new rules make this flat-fee donor compensation model illegal? Will safety improve and commodification and exploitation be avoided? No, the E.U. will just become even more dependent on the United States."

Smart toilets and data privacy

 Something to sit and think about:

Smart toilets could leak your medical data, warn security experts. by Matthew Sparkes New Scientist, Volume 259, Issue 3456, 2023, Page 14, ISSN 0262-4079, https://doi.org/10.1016/S0262-4079(23)01720-7. 

"A range of start-ups and research projects have developed smart toilets to monitor everything from heart rate to the consistency of stools and the presence of certain proteins in urine that indicate disease. One device even features an “anus camera” that takes a photo from below for identification, something that has been described as the “polar opposite of facial recognition”.*

...

"One concern was the privacy of people other than the owner: are visitors consenting to have photographs or measurements taken? There were also worries about the risk of losing sensitive data to hackers, as well as the possibility of companies selling the data on. And if smart toilets were installed in public areas or workplaces, there would be questions about who has access to that data, it was argued.The group of experts concluded that smart toilets shouldn't be sold as consumer devices, but instead as medical devices that have to meet high regulatory standards for privacy and safety (arXiv, doi.org/ksx5).

"Chase Moyle at smart toilet start-up Coprata says he set out to build a consumer device because creating a medical device under US Food and Drug Administration regulations would raise the price by a factor of 10. It would also mean that, in the US, insurance companies would only offer it to people with diagnosed conditions.

...

"Alan Woodward at the University of Surrey, UK, says so-called internet of things (IoT) devices, such as heart rate monitors and CCTV cameras, have often been found to have security flaws, including a smart toilet with a computer-controlled bidet. He fears the same could be true for medical-focused smart toilets. “With a lot of IoT devices, security has never been uppermost in the mind and yet something like a smart toilet is collecting some very personal data,” he says. “They're making these weird devices because they can, but nobody's thought through ‘should we?’”

‘Smart toilet’ monitors for signs of disease. A disease-detecting “precision health” toilet can sense multiple signs of illness through automated urine and stool analysis, a new Stanford study reports.  April 6, 2020 - By Hanae Armitage, Stanford Medicine News

"One of the most important aspects of the smart toilet may well be one of the most surprising — and perhaps unnerving: It has a built-in identification system. “The whole point is to provide precise, individualized health feedback, so we needed to make sure the toilet could discern between users,” Gambhir said. “To do so, we made a flush lever that reads fingerprints.” The team realized, however, that fingerprints aren’t quite foolproof. What if one person uses the toilet, but someone else flushes it? Or what if the toilet is of the auto-flush variety?

"They added a small scanner that images a rather camera-shy part of the body. You might call it the polar opposite of facial recognition. In other words, to fully reap the benefits of the smart toilet, users must make their peace with a camera that scans their anus.

“We know it seems weird, but as it turns out, your anal print is unique,” Gambhir said. The scans — both finger and nonfinger — are used purely as a recognition system to match users to their specific data. No one, not you or your doctor, will see the scans."

Nobel Symposium on Social Networks Lund, Sweden, August, 2023

A Nobel Symposium on Social Networks was held in Lund last month.The papers don't appear to be online, but it ended with a round table discussion:
"You can join in online when the symposium ends with an open “round table discussion” with a panel of leading scientists on August 24 at 14:00. The discussion will be introduced by Tommy Andersson, Professor in Economics at LUSEM and Member of the Committee for the Prize in Economic Sciences in Memory of Alfred Nobel.

The panelists are Prof. Matthew Jackson, Prof. Albert-Laszlo Barbasi, Prof. Kathleen M. Carley, Prof. Damon Centola, Prof. Vittoria Colizza, and Prof. David Lazer."

Stanford was well represented. Aside from my colleague Matt Jackson, Mark Granovetter joined the symposium itself by Zoom (which I guess is a weak link).
