Hiring former Supreme Court Clerks (is expensive)

 The Washington Post has the story:

Clerks for hire: The Supreme Court recruiting race. Supreme Court clerks are offered bonuses of up to $500,000 to join law firms  By Tobi Raji

"Only around three dozen law clerks work for the justices during each one-year term, which means these lawyers — and their unparalleled knowledge of the court — are in incredibly high demand. Jones Day, the leader in the race to recruit and hire as many clerks as possible, announced last month that it snagged 8 law clerks, all of whom worked for conservative justices during the term that began in October 2022.

...

"The recruitment is so competitive that signing bonuses for Supreme Court law clerks have reached a new high — $500,000, according to a spokeswoman for law firm Gibson, Dunn & Crutcher. Such a sum far exceeds the salaries paid to the justices — the clerks’ former bosses — who are paid slightly less than $300,000 a year.

"The bonuses — alongside annual starting salaries of more than $200,000, which alone are nearly triple Americans’ median household income — are the product of a decades-long competition among elite law firms seeking any advantage they can find in arguing high-profile cases before the Supreme Court. They view the clerks’ experience and knowledge of the court as profitable assets that attract clients in a highly specialized sector of the law, and they see clerkships as effective filtering devices in identifying promising hires, according to interviews with former Supreme Court clerks, lawyers and experts."

Refugees in the middle east, since 1949

 Al Jazeera provides some interesting statistics and graphics in a story about UNRWA, the United Nations Relief and Works Agency for Palestine Refugees in the Near East, which was founded in 1949 to provide aid to Palestinian refugees from the war that followed Israel's independence.  While Palestinians who left the middle east are of course no longer refugees (just as Jews who were refugees from Arab countries at that time are now citizens of the countries in which they settled) that's not the case for the Palestinians who fled to neighboring Arab countries, nor for their children or grandchildren. See the map below. 

Here's the Al Jazeera story:

Which countries have cut funding to UNRWA, and why?. The UN urges continued funding to UNRWA’s ‘lifesaving’ aid in Gaza, after several Western countries cut aid to the agency.  28 Jan 2024

"The United Nations agency for Palestinian refugees (UNRWA), considered a lifeline for two million people in the besieged enclave, has suffered funding cuts after several of its staff were accused by Israel of involvement in the October 7 Hamas attack."

"There are tradeoffs everywhere" Alfred Spector on artificial intelligence.

 Alfred Spector has written an article called : Gaining Benefit from AI and Data Science: A Three-Part Framework. Among other things, he argues that neither technologists alone, nor ethicists alone, will find themselves automatically well equipped to think about the tradeoffs involved in developing, deploying, and regulating artificial intelligence.  

Here's a short (5 min) video produced by the ACM in which he calls for a broad approach.

Experiments for organ allocation (an idea whose time may be coming)

 Experiments to improve how deceased donor organs are allocated to waiting patients seem like a good idea...

OPTN Task Force sets goal of achieving 60K transplants by 2026Jan 26, 2024 

“we need to move quicker, be more responsive, and deliver results for the patients we serve,” said Dianne LaPointe Rudow, DNP, president of the OPTN Board of Directors. “The reality is that while the number of transplants continues to grow, so does the non-use of available organs and allocations of organs out of the intended sequence of offers.

...

"The need is clear. In the case of kidneys, the most transplanted organ, the number of kidneys recovered from deceased donors increased by 56 percent between 2018 to 2023. Yet the number of kidney transplants only increased by 44 percent, meaning that approximately one quarter of kidneys recovered were not transplanted.

...

"Under a proposed variance for expedited placement, currently out for public comment, the task force intends to develop a series of rapid, small-scale tests of innovative organ placement approaches and assess their outcomes to evaluate whether they could be incorporated into future OPTN policies. The task force also has committed to prioritizing studies that evaluate potential frameworks for allocating hard-to-place organs to increase the number of transplants and lower non-use rates."

Open source intelligence purchases that would require a warrent to be collected directly

 The NYT has the story:

N.S.A. Buys Americans’ Internet Data Without Warrants, Letter Says By Charlie Savage, January 25

"The National Security Agency buys certain logs related to Americans’ domestic internet activities from commercial data brokers, according to an unclassified letter by the agency.*

...

"In [a different] letter, General Nakasone wrote that his agency had decided to reveal that it buys and uses various types of commercially available metadata for its foreign intelligence and cybersecurity missions, including netflow data “related to wholly domestic internet communications.”

"Netflow data generally means internet metadata that shows when computers or servers have connected but does not include the content of their interactions. Such records can be generated when people visit different websites or use smartphone apps, but the letter did not specify how detailed the data is that the agency buys."

...

"Law enforcement and intelligence agencies outside the Defense Department also purchase data about Americans in ways that have drawn mounting scrutiny. In September, the inspector general of the Department of Homeland Security faulted several of its units for buying and using smartphone location data in violation of privacy policies. Customs and Border Protection has also indicated that it would stop buying such data."

#######

*Here is the letter referred to above. It is not in fact a letter "by the agency," but is from a senator to the Director of National Intelligence.

"As you know, U.S. intelligence agencies are purchasing personal data about Americans that would require a court order if the government demanded it from communications companies.  

...

"The FTC notes in its complaint [against the data broker X-Mode Social] that the reason informed consent is required for location data is because it can be used to track people to sensitive locations, including medical facilities, places of religious worship, places that may be used to infer an LGBTQ+ identification, domestic abuse shelters, and welfare and homeless shelters. The FTC added  that the sale of  such data poses an unwarranted intrusion into the most private areas of consumers lives. While the FTC's -Mode social complaint and order are limited to location data, internet metadata can be equally sensitive. Such records can identify Americans who are seeking help from a suicide hotline or a hotline for survivors of sexual assault or domestic abuse, a visit to a telehealth provider focusing on specific healthcare need, such as those prescribing and delivering abortion  pills by mail, or reveal that someone likely suffers from a gambling addiction."

The DOJ on competition for workers

 A lot of market design is done by regulators, and some of that is done to enforce existing laws.  Here's a report from the Department of Justice, focusing on four cases involving payment to workers (including authors of books).

Athey, Susan, Mark Chicu, Malika Krishna, and Ioana Marinescu. "The Year in Review: Economics at the Antitrust Division, 2022–2023." Review of Industrial Organization (2024): 1-20.

"In this review article, we report on five enforcement matters that expanded the scope of enforcement by the Division. The first four enforcement matters highlight a number of the Division’s actions to protect labor market competition in criminal and civil merger and non-merger cases. These include: criminal enforcement against a provider of contract health care staffing services that allocated nurse employees through a no-poaching agreement and agreed to fix the wages of those nurses; civil enforcement to stop an e-Sports league from effectively imposing a salary cap on its players; civil enforcement to stop a conspiracy among poultry processors to share information about worker compensation; and the successful challenge of a merger between two of the largest book publishers in the U.S., which preserved competition for books that will benefit authors."

Guns and drugs on the U.S. Mexico border

 Here are two stories about some of the illegal traffic on the border between the U.S. and Mexico.

First, the war on drugs is fought with American guns on both sides:

The NY Times has the story:

Appeals Court Revives Mexico’s Lawsuit Against Gunmakers. The decision, which is likely to be appealed, is one of the most significant setbacks for the gun industry since passage of a federal law that provided immunity from some lawsuits.  By Glenn Thrush  Jan. 22, 2024

"A federal appeals panel in Boston ruled on Monday that a $10 billion lawsuit filed by Mexico against U.S. gun manufacturers whose weapons are used by drug cartels can proceed, reversing a lower court that had dismissed the case.

"The decision, which is likely to be appealed, is one of the most significant setbacks for gunmakers since passage of a federal law nearly two decades ago that has provided immunity from lawsuits brought by the families of people killed and injured by their weapons.

"Mexico, in an attempt to challenge the reach of that law, sued six manufacturers in 2021, including Smith & Wesson, Glock and Ruger. It contended that the companies should be held liable for the trafficking of a half-million guns across the border a year, some of which were used in murders.

...

" lawyers for Mexico, assisted by U.S. gun control groups, claimed that the companies “aided and abetted the knowingly unlawful downstream trafficking” of their guns into Mexico.

"Gun violence is rampant in Mexico despite its near-blanket prohibition of firearms ownership.

"About 70 to 90 percent of guns trafficked in Mexico originated in the United States, according to Everytown Law, the legal arm of the gun control group founded by the former mayor of New York Michael R. Bloomberg.

"Gun control advocates hailed the decision on Monday by a three-judge panel, describing it as a milestone in holding the gun industry accountable."

***********

As for drugs, it turns out that harm reduction drugs are highly controlled in Mexico, so illegal drugs also flow both ways.

Here's that story, from the Guardian:

Carriers sneak life-saving drugs over border as Mexico battles opioid deaths  People forced to bring overdose-reversal drug naloxone from US, as critics accuse Mexican government of creating shortage. by Thomas Graham in Tijuana, Tue 23 Jan 2024 

"Every day, people cross the US-Mexico border with drugs – but not all of them are going north. Some head in the opposite direction with a hidden cargo of naloxone, a life-saving medicine that can reverse an opioid overdose but is so restricted as to be practically inaccessible in Mexico.

"This humanitarian contraband is necessary because Mexico’s border cities have their own problems with opioid use – problems that activists and researchers say are being made more deadly by government policy.

“Mexico has long seen itself as a production and transit country, but not a place of consumption,” said Cecilia Farfán Méndez, a researcher at the University of California at San Diego. “And a lot of the conversation is still around that being a US problem – not a Mexican one.”

...

"The situation has been exacerbated by a government policy that, aside from cutting budgets for harm reduction services like PrevenCasa, has also created shortages of life-saving medicines for opioid users.

"In response to the fentanyl crisis, authorities in the US made naloxone available without a prescription. Naloxone vending machines have proliferated across the country.

"But in Mexico naloxone remains strictly controlled – despite the efforts of some senators from Andrés Manuel López Obrador’s own party, Morena, who proposed a law to declassify it.

"The president, popularly known as Amlo, has criticised naloxone, asking whether it did any more than “prolong the agony” of addicts, and questioning who stood to profit from its sale."

The war on drugs is a war

The war on drugs doesn't begin at U.S. borders.

Here's a dispatch from Ecuador, in the WSJ:

Ecuador Is at War With Drug Gangs, President Says. Troops patrolled the country’s largest city a day after a series of attacks against the new government  By Kejal Vyas and Ryan Dubé

"Ecuador is at war with drug gangs, President Daniel Noboa said Wednesday, as troops patrolled the country’s largest city, Guayaquil, a day after gunmen took over a TV studio and launched a series of attacks against the Andean nation’s new government.

“We are in a noninternational armed conflict,” Noboa said in a radio interview. “We are in a state of war. We cannot give in to those terrorist groups.”

"The armed forces and national police scrambled to bring order to Guayaquil, and shops and schools were closed after a series of coordinated attacks Tuesday on shopping centers, hospitals and a university left at least 11 people dead.

"Drug-trafficking gangs in recent years have turned Ecuador into one of the world’s most violence-plagued nations as they battled over the cocaine trade.
...
" Once relatively peaceful, Ecuador has seen the homicide rate shoot up from less than six per 100,000 in 2018 to more than 40 in 2023, said police."
###########

And here's one from Belgium, in the Washington Post:

Belgian customs officers seized three times as much cocaine in the port of Antwerp last year as U.S. customs and border officials seized in all of the United States.  By Gerrit De Vynck

"The head of Belgium’s customs service said in an interview that especially big seizures in the fall appeared to have prompted a violent backlash, along with a new issue: Authorities haven’t always been able to destroy what they’ve confiscated before drug gangs try to steal it back.

“Attacking the police, attacking the customs, this is not something you see in Europe,” said Kristian Vanderwaeren, director general of Belgium’s customs agency. “I was really afraid that my people would be killed if this would continue.”
...
"“The criminal organization was not afraid to come to a facility and capture their cocaine, even if it meant they would kill a customs officer,” Vanderwaeren said.
...
"According to Europol, the European Union’s law enforcement agency, Ecuador and its main port of Guayaquil have been the biggest sources of cocaine destined for Europe, reflecting how Mexican and Albanian gangs have infiltrated the country. This month, the president of Ecuador declared a “state of war” against drug gangs, after a series of assassinations, prison breaks and bombings there."

Reporting and misreporting from Organ Procurement Organizations (OPOs)

 Because there are shortages of organs for transplant, it is important to measure how successful Organ Procurement Organizations (OPOs) are at recovering and transplanting organs.  But sometimes definitions can get in the way, and this was the case in islet transplants from deceased donors, into patients with diabetes.  Pancreatic islets are the cells that produce insulin, and it was (and I think still is) regarded as an experimental procedure to transplant islets from a deceased donor's pancreas, rather than the whole pancreas.  So islet transplantation was classified as a research activity.

To encourage this use of deceased donor pancreases, recovery of a pancreas "for research" was counted as a transplant. But some OPO's have heavily gamed this, reporting that they recovered a pancreas when the "research" wasn't connected to transplantation.  That loophole is now being closed.

Here's a January 18 memo from HHS, CMS, Center for Clinical Standards and Quality

Organ Procurement Organization (OPO) Conditions for Coverage – Definition Clarification 



"Background:

"The OPO CfCs are intended to drive improvements in organ procurement and transplantation through, among other provisions, the donor and transplantation outcome measures. OPOs are required to report data related to pancreata procured for research, and this data is incorporated into calculations used to assess compliance with the donor and transplant outcome measures and are used for re-certification purposes. To facilitate accurate reporting of data related to pancreata donors, the term “donor” is defined in CMS regulation to specify that, among other requirements, an individual would be considered a donor even if only the pancreas is procured and is used for research or islet cell transplantation.

"CMS has noted a significant increase in the number of pancreata procured since this definitionwas revised in 2020, raising questions about the interpretation of this definition by OPOs and how this definition is applied to reporting data related to donors of pancreata used for islet cell research. There is a concern that the increase in pancreata procured may not reflect a meaningful increase in pancreata being actually used for islet cell research, and instead may reflect pancreata procured for other purposes. This memo is clarifying that the pancreata must be used for islet cell research. 

...

"In summary, this memo is clarifying that consistent with the Pancreatic Islet Cell Transplantation Act of 2004, only pancreata procured by an OPO and used for islet cell transplantation or research shall be counted"

Legislative proposals to help living kidney donors

 Martha Gershun brings us up to date on various proposed pieces of legislation to help organ donors and increase access to transplants.

Legislative Efforts to Support Living Kidney Donors,  by Martha Gershun, Guest Blogger

"As a member of the Expert Advisory Panel to the Kidney Transplant Collaborative, I have been honored to provide input during the development of the organization’s priority legislation, the Living Organ Volunteer Engagement (LOVE) Act.  This legislation would help build a comprehensive national living organ donor infrastructure that would support a national donor education program, create a donor navigator system, ensure appropriate donor cost reimbursement, collect essential data, and improve all aspects of living organ donation across the country, substantially reducing barriers that limit participation today.

Key provisions of the LOVE Act would:

  • Provide reimbursement for all direct and indirect costs for living donation, including lost wages up to $2,500 per week.
  • Provide life and disability insurance for any necessary care directly caused by donation.
  • Modify NLDAC rules so neither the recipient’s income nor the donor’s income would be considered for eligibility.
  • Provide for new public education program on the importance and safety of living organ donation.
  • Provide for new mechanisms to collect and analyze data about living organ donation to enable evidence-based continuous process improvement.

Numerous other federal proposals are also currently vying for support to address barriers to living donation on a national level.  They include:

Living Donor Protection Act (H.R. 2923, S. 1384)

  • Prohibits insurance carriers from denying, canceling, or imposing conditions on policies for life insurance, disability insurance, or long-term care insurance based on an individual’s status as a living organ donor.
  • Specifies that recovery from organ donation surgery constitutes a serious health condition that entitles eligible employees to job-protected medical leave under the Family and Medical Leave Act.

Organ Donor Clarification Act (H.R. 4343)

  • Clarifies that reimbursement to living organ donation is not “valuable consideration” (I.e., payment), which is prohibited under the National Organ Transplant Act (NOTA)
  • Allows pilot programs to test non-cash compensation to living organ donors.
  • Modifies NLDAC rules so the recipient’s income would no longer be considered for eligibility.

Living Organ Donor Tax Credit Act (H.R. 6171)

  • Provides a $5,000 federal refundable tax credit to offset living donor expenses.

Honor Our Living Donor (HOLD) Act (H.R. 6020)

  • Modifies NLDAC rules so the recipient’s income would no longer be considered for eligibility.
  • Requires public release of annual NLDAC report.

Helping End the Renal Organ Shortage (HEROS) Act

  • Provides a $50,000 refundable federal tax credit over a period of five years for non-directed living kidney donors.

And here's one more, from the Coalition to Modify NOTA

AEA's lockbox: recording allegations while reserving the right to report them

The American Economic Association has announced that they have initiated a Reporting Lockbox – Now Available to Members, meant to allow members to record transgressions such as sexual harassment while reserving and preserving the right to report them later, if the same individual is named as an offender by someone else. The idea is to allow repeat offenders to be identified, even if each offense might be too ambiguous to justify an immediate complaint.

"The Reporting Lockbox enables AEA members who are not yet ready to file a formal complaint to log circumstances or conduct by other members that may violate the AEA’s policy against harassment, discrimination, and retaliation. If two or more AEA members log alleged incidents of harassment, discrimination, or retaliation perpetrated by the same person by making entries in this digital archive and indicating a willingness to communicate with other alleged victims, each member who logged an incident will be contacted separately to determine if each would consider communicating with the other members, or to otherwise keep the submission active or withdraw it. A mutual decision to contact the other members who logged an incident about the same alleged perpetrator could lead to their filing a formal complaint with the AEA Ethics Committee or pursuing other options outside of the AEA.

"The AEA will not have access to the Reporting Lockbox, and therefore will not know the identities of members or persons of interest unless action is taken by the members through the filing of a formal complaint to the AEA. Users of the Lockbox can edit or remove entries at any time."

Incentives and mis-incentives in science (Freakonomics part II)

 Freakonomics has a second post on fraud in science, and you can listen or read the transcript here:

Can Academic Fraud Be Stopped?

Two quotes stood out for me:

1. VAZIRE: Oh, I don’t mind being wrong. I think journals should publish things that turn out to be wrong. It would be a bad thing to approach journal editing by saying we’re only going to publish true things or things that we’re 100 percent sure are true. The important thing is that the things that are more likely to be wrong are presented in a more uncertain way. And sometimes we’ll make mistakes even there. Sometimes we’ll present things with certainty that we shouldn’t have. What I would like to be involved in and what I plan to do is to encourage more post-publication critique and correction, reward the whistleblowers who identify errors that are valid and that need to be acted upon, and create more incentives for people to do that, and do that well.

...

2. BAZERMAN: Undoubtedly, I was naive. You know, not only did I trust my colleagues on the signing-first paper, but I think I’ve trusted my colleagues for decades, and hopefully with a good basis for trusting them. I do want to highlight that there are so many benefits of trust. So, the world has done a lot better because we trust science. And the fact that there’s an occasional scientist who we shouldn’t trust should not keep us from gaining the benefit that science creates. And so one of the harms created by the fraudsters is that they give credibility to the science-deniers who are so often keeping us from making progress in society.

It's a dominant strategy for deferred acceptance proposers to state true preferences in the marriage problem: simple proof

This post is not entirely self-contained, it is in some sense a continuation of and addition to my talk last year at the Simons Institute, which you can see at this link: 

Simple Proofs of Important Results in Market Design-- (video of my talk at Berkeley's Simons Institute)

In that talk (based on work I'm doing with Mike Ostrovsky) I defined the marriage model of Gale and Shapley, gave necessary definitions,  and following the style of their original article, I showed simple, verbal proofs of a number of results, including the constant employment ("lone wolf") theorem:

Constant employment theorem: In a "marriage market"(M,W, P) with strict preferences, the set of people who are single is the same for all stable matchings.

Now based on that theorem, here's a simple proof of the dominant strategy theorem, inspired by a  very short proof (with attributions to Alex Teytelboym and Ravi Jagadeesan) in Nick Arnosti's recent blog post A Short Proof of the Truthfulness of DA by Nick Arnosti 2023/10/01 

Here's the theorem to be proved:

Dominant Strategy Theorem (Dubins and Freedman, Roth): In the M-optimal stable mechanism for the marriage problem (e.g. when the man-proposing deferred acceptance algorithm is used, which produces the most favorable stable matching for every man) it is a dominant strategy for each man i to state a preference list corresponding to his true preferences ≻.


Notation: for any preference ≻′ of player i, an outcome is ≻′-stable if it is stable when i reports ≻′ and everyone else's preferences remain constant.

Proof (following Arnosti)

Suppose that the theorem is false. That is, suppose there exist preferences for all other agents such that when i reports ≻, the resulting ≻-stable matching μ gives μ(i)=w, and when i reports ≻′ ≠ ≻, the resulting ≻′-stable matching μ′ gives μ′(i)=w′≻w. (Note that the final comparison is ≻, i.e. take ≻ to be i's true preference list.)

Consider the market in which i lists w′ as the only acceptable woman (and everyone else's preferences remain fixed). We'll see that this will lead to a contradiction with the constant employment theorem, by implying that there must exist a {w'}-stable matching in which i matches to w′, and another {w'}-stable matching in which i is unmatched. 

1. The matching μ′ assigns i to w′. Because it is ≻′-stable, it must also be {w′}-stable: the only difference between ≻′ and {w'} is that we have removed women from i’s list, which clearly does not create any new blocking pairs.

Note: this step uses only the definition of stability.

2. Let ≻′′ be the deviation in which i truncates ≻ below w′ (i leaves everyone below w′ off of his list), and let μ′′ be the resulting matching.

a. The matching μ′′ leaves i unassigned.  This follows from the fact that, if it matched i, then μ″ would be ≻-stable, since ≻ differs from ≻'' only in that it restores the truncated elements of i's preference, which would be below i's match and hence not introduce any new blocking pairs (since it wouldn't change i's match). But  μ″ can't be ≻-stable,  because w is i’s best ≻-stable partner by assumption, and is worse than all women listed in ≻′′.*

Note: this step uses the definition of stability and fact that μ is optimal for i.

b. Because μ′′  (which leaves i unassigned) is ≻′′-stable, it is also {w′}-stable: the only difference between ≻′′ and {w′} is that we have removed women from i’s list, which does not create any new blocking pairs).

Note: this step uses only the definition of stability.

To recap: μ′ and μ′′ must both be {w′}-stable, but i is matched to w′ by μ′ and unmatched by μ′′ (a contradiction).

This completes the proof.

*Note that the reason μ′′ isn't ≻-stable is that it leaves i unassigned, and so creates new blocking pairs involving i with respect to his true full preferences.

AEA announces changes in how journals will be produced, financed and distributed

Yesterday's AEA Member Announcements include some substantial changes in how the AEA journals will be produced, distributed, and financed.

The AEA will phase out print journals over the next year by no longer offering print subscriptions for members and institutional subscribers as of February 1.  Existing print subscriptions for members and institutions will be honored through January 2025 but will be unable to be renewed.

In line with most other leading journals, the AEA will end payments to referees for reviews invited on or after February 1.

Collecting publication fees from those benefiting most from the AEA publications program distributes costs of the program more equitably than raising submission fees. With this in mind, the AEA will implement a page charge of $15 per typeset page for published articles submitted after February 1, to be paid by authors, and with provisions to waive the fee under certain circumstances. This page charge will not apply to formally solicited manuscripts (such as Presidential addresses) and will not include articles in the Journal of Economic Literature, Journal of Economic Perspectives, or AEA Papers and Proceedings.   

###########

I wasn't party to these discussions, but I wouldn't be surprised if someone mentioned that per-page charges will feel anachronistic once print journals are no longer produced.  But maybe they will be a mild incentive for brevity (as would per-word charges, which might however inadvertently incentivize sesquipedaleanism).

Hitmen are common in film but otherwise scarce

 The NYT considers the prevalence of hitmen in movies, and why it's hard to find one in real life.

Hit Men Are Easy to Find in the Movies. Real Life Is Another Story.  By Jesse McKinley

"experts in law enforcement and international espionage say that murders-for-hire are notoriously difficult to successfully arrange, let alone get away with.

"Take, for example, what prosecutors say was a recent foiled plot to kill a Sikh separatist in New York City, which American intelligence officials believe was ordered by the Indian government. Once the plot reached the point where the alleged conspirators needed to employ a killer, things got complicated: The would-be hit man turned out to be an undercover agent working for the U.S. government.

...

"Law enforcement officials and academics who study killers-for-hire put them into several large buckets. There are the civilians engaged in everyday murder plots, which often end in sloppy or tragic fashion.

"There are also hit men for the mob, the enforcers working in-house to illegally police the criminal underworld. These killers, perhaps the source of most urban lore about the illicit profession, have been luridly overexposed in shows like “The Sopranos” and films like “The Godfather” and “Goodfellas.”

"Employed in a similar fashion are so-called sicarios, whose use by drug cartels has been heinously prolific at times. And of course there are also the professionals employed by government intelligence agencies, who have been suspected in assassinations in London and elsewhere.

...

"Statistics from the New York State Division of Criminal Justice Services show that in 2022 there were only seven arrests statewide for contract killing, which the state considers first-degree murder. And that was a banner year for arrests for such badness, matching the total for the five previous years combined. Murder for hire is also a federal crime, with penalties ranging from fines and lengthy prison time for failed attempts to life imprisonment or the death penalty “if death results.”

Matching and market design in the latest GEB (stack overflow...)

 The current (January 2024) issue of Games and Economic Behavior presents an increasingly common dilemma (faced by scholars in burgeoning fields, and maybe by aging scholars...). Papers I should read are being written much faster than I can read them.

Here are 9 papers in that issue that are pretty clearly about matching and market design (which leaves out some papers on auctions and one on unraveling of the timing of markets) :

  1. Obvious manipulations of tops-only voting rules
