NRMP Statement On Interviewing

 The National Resident Matching Program (NRMP) has a statement on interviewing, which precedes the NRMP match for new American doctors, and that reflects concerns that the interviewing process has become congested.

NRMP Statement On Interviewing

"The National Resident Matching Program® (NRMP®) has heard the concerns of learners and programs in the medical education community about the interview process and wants to encourage equitable practices among applicants and programs. As such we have developed the following recommendations. Although especially true during the enduring times of the pandemic, the recommendations align with the NRMP’s long-standing commitment to maintaining a fair, efficient, reliable, and transparent process for all. Recommendations also foster well-being among all parties.

"NRMP Recommendations for Programs:

1. Programs should conduct all interviews virtually for the 2021-2022 cycle.

2. Programs should extend interview offers that equal, not exceed, the total number of available interview slots.

3. Applicants should be given a minimum of 48 hours to respond to an interview offer.

"NRMP Recommendations for Applicants:

1. Applicants should make timely decisions about interview offers and promptly notify programs in which they are no longer interested, freeing up interview slots.

2. Applicants should give ample, adequate (e.g., one week) notice to programs in the event they change their minds and decline accepted interviews."

Promoting Quality in Research: the inaugural Einstein Foundation Awards, 2021

 I had the privilege of being a member of the jury for the Einstein Foundation Awards, which were awarded yesterday for the first time.

Here's the award booklet: 

EINSTEIN FOUNDATION AWARD 2021 PROMOTING QUALITY IN RESEARCH

Individual Award 2021:  Paul Ginsparg

"Preprints have been shared in the physics community since the early 1950s but mostly among well established professors. Physicist Paul Ginsparg, who receives the Einstein Foundation’s Individual Award, set out to democratize access to scientific results. Today, his preprint server arXiv has spread to many other fields—and made science progress more efficient and fairer."

Institutional Award 2021: The Center for Open Science

"Open research is on the rise, but a lot of research information still remains behind closed doors. The Center for Open Science, recipient of the Institutional Award, advocates for more transparency and open access, training scientists, publishers and funders, providing technology and policy recommendations. With this multi pronged approach, it has helped create an open science community which is becoming ever more self-sustaining."

Early Career Researcher Award 2021: "ManyBabies5: Teaming up for Developmental Science → manybabies.github.io/MB5

"Unlike adult subjects, babies cannot tell you what they are thinking. Therefore, researchers studying infant development use looking patterns to understand how babies think and feel about the world. “An overwhelming majority of studies use looking time to make inferences about infant cognition,” comments Martin Zettersten from Princeton University in the United States. But what exactly is it that drives babies to pay attention to different things? To come up with a statistically sound answer to this question, he and his colleague Jessica Kosie initiated ManyBabies5, a large international consortium of infant researchers. “We aim to increase diversity amongst researchers and test subjects alike and collaboratively want to come up with the best test possible on how different factors matter in infant looking time,” Jessica Kosie explains. To that end, the ManyBabies team will put together a diverse and sizeable sample of infants around the world. “To me, team science is a useful tool for producing high quality, robust science,” says Martin Zettersten. “Embracing this approach as a field as many groups are doing right now—that feels revolutionary to me.”

THE JURY The Einstein Foundation Council has convened an outstanding group of scholars representing the natural sciences, the humanities, and the social sciences. The international jury is presided over by Dieter Imboden and both defines the objectives of the award and selects the awardees.

Mail order catalogs, downtown department stores, suburban malls, and modern home delivery

 Here's a 10 minute video in which I discuss how retail markets have changed over the last century and more, with the invention of mail order catalogs, and the growth of downtown department stores (in part as a result of urban public transportation), and then suburban shopping malls, before our current age of digital commerce and home delivery.

This was my discussion of talks by Rob Townsend and David Autor at the October zoom conference

An IVF mixup of babies

 Here are the stories, from the Guardian, and the NY Times:

Guardian:

California women gave birth to each other’s babies after IVF mix-up. Couples to sue clinic after raising girls for months that were not theirs, says lawsuit, before babies were swapped back

"Two California couples gave birth to each other’s babies after a mix-up at a fertility clinic and spent months raising children that were not theirs before swapping the infants, according to a lawsuit filed in Los Angeles.

"Daphna Cardinale said she and her husband, Alexander, had immediate suspicions that the girl she gave birth to in late 2019 was not theirs due to the child’s darker complexion.

"They suppressed their doubts because they fell in love with the baby and trusted the in vitro fertilisation process and their doctors, she said. Learning months later that she had been pregnant with another couple’s baby, and that another woman had been carrying her child, caused enduring trauma, she said.

...

"The two other parents involved in the alleged mix-up wish to remain anonymous and plan a similar lawsuit in the coming days, according to the attorney Adam Wolf, who represents all four parents.

"The lawsuit claims CCRH mistakenly implanted the other couple’s embryo into Daphna and transferred the Cardinales’ embryo – made from Daphna’s egg and Alexander’s sperm – into the other woman.

"The babies, both girls, were born a week apart in September 2019. Both couples unwittingly raised the wrong child for nearly three months before DNA tests confirmed that the embryos were swapped, according to the filing.

“The Cardinales, including their young daughter, fell in love with this child, and were terrified she would be taken away from them,” the complaint says. “All the while, Alexander and Daphna did not know the whereabouts of their own embryo, and thus were terrified that another woman had been pregnant with their child – and their child was out in the world somewhere without them.”

"The babies were swapped back in January 2020.

"Mix-ups like this are exceedingly rare, but not unprecedented. In 2019, a couple from Glendale, California, sued a separate fertility clinic, claiming their embryo was mistakenly implanted in a New York woman, who gave birth to their son as well as a second boy belonging to another couple.

NY Times:

‘We Had Their Baby, and They Had Our Baby’: Couple Sues Over Embryo ‘Mix-Up’  Daphna and Alexander Cardinale, the plaintiffs in a lawsuit against a Los Angeles-area fertility clinic, say they endured a painful custody exchange after DNA testing.  By Neil Vigdor

...

"Peiffer Wolf Carr Kane & Conway, the law firm representing the Cardinales, estimated that the couple had paid $50,000 to the fertility clinic for the treatments.

...

"Mr. Cardinale, 41, said during the news conference on Monday that the most upsetting aspect of the ordeal had been breaking the news to the couple’s older daughter, who begged her parents to keep the baby.

“How do you explain that to a 5-year-old?” Mr. Cardinale said."

A naturally occurring deceased-donor-initiated kidney exchange chain, by Maghen and Veale

 Here's an interesting case report, from the innovative UCLA transplant center, about a kidney exchange chain actually, if not officially, initiated by a deceased donor.

With “reverse engineering” were some living donor kidney chains in actuality triggered by deceased donors?  by Ariella Maghen and Jeffrey Veale, Clinical Transplantation, First published: 21 September 2021 https://doi.org/10.1111/ctr.14491

"Mr. M is a 58-year-old polycystic kidney disease patient waiting for a kidney transplant in the United States (US). Although his wife Mrs. M offered to donate her kidney to him, they were not a compatible match. While waiting to be “exchanged or swapped” with another donor/recipient pair facilitated by the National Kidney Registry (NKR), Mr. M received a rare offer for a “perfectly-matched” (zero-mismatch) deceased donor (DD) kidney. Only 5% of candidates receive a perfectly matched kidney from a DD; Mr. M accepted the offer and underwent transplantation in February 2020. Currently, his allograft is functioning beautifully, and he states never feeling better. 

"One may think Mrs. M feels relief now and that she is “off-the-hook” to donate. But au contraire as she has completed the extensive donor evaluation and remains in the mindset to donate. Mrs. M's gratitude towards the DD family's gift to her husband motivated her to “pay-their-generosity-forward” and now donate her kidney.

"Mrs. M's donation performed on October 21, 2020, brings greater awareness to the concept of a DD triggered kidney chain, a relatively novel phenomenon in the United States.

...

"This case elucidates how transplant chains, believed to be initiated by non-directed living donors, when reverse-engineered may in actuality have been triggered by DDs who were at the pole position. Although this may be one of the first reported cases, it is possible that other transplant centers have been encouraging the allocation of donors in this fashion. There are likely more living donors who may still want to donate their kidney even after their intended recipient received a DD transplant via “zero-mismatch” or “high-PRA” offers."

************

Italy seems to be among the first places to formally follow up on the idea of deceased donor chains. See:

Transplant InternationalVolume 33, Issue 10 p. 1177-1184, Kidney exchange strategies: new aspects and applications with a focus on deceased donor-initiated chains, by Lucrezia Furian,Antonio Nicolò,Caterina Di Bella,Massimo Cardillo,Emanuele Cozzi,Paolo Rigotti  First published: 09 August 2020  https://doi.org/10.1111/tri.13712

Summary: Kidney paired donation (KPD) is a valuable way to overcome immunological incompatibility in the context of living donation, and several strategies have been implemented to boost its development. In this article, we reviewed the current state of the art in this field, with a particular focus on advanced KPD strategies, including the most recent idea of initiating living donor (LD) transplantation chains with a deceased donor (DD) kidney, first applied successfully in 2018. Since then, Italy has been running a national programme in which a chain-initiating kidney is selected from a DD pool and allocated to a recipient with an incompatible LD, and the LD’s kidney is transplanted into a patient on the waiting list (WL). At this stage, since the ethical and logistic issues have been managed appropriately, KPD starting with a DD has proved to be a feasible strategy. It enables transplants in recipients of incompatible pairs without the need for desensitizing and also benefits patients on the WL who are allocated chain-ending kidneys from LDs (prioritizing sensitized patients and those on the WL for longer).

...

"Melcher et al. [10] suggested merging DD programmes with KPD programmes in 2016, an idea explored more recently in a concept paper issued by the Organ Procurement and Transplantation Network (OPTN) [11].

Deceased donor chains: Market design language is entering transplantation

Monday, April 11, 2016

Using deceased donor kidneys to start living donor kidney exchange chains

Online and Matching-Based Market Design (forthcoming in 2022), edited by Echenique, Immorlica, and Vazirani

 What to read in 2022? Here's a teaser...

Online and Matching-Based Market Design, forthcoming in 2022 from Cambridge University Press

Editors: Federico Echenique, Nicole Immorlica, Vijay V. Vazirani  

With a Foreword by Alvin E. Roth

The publisher's leaflet describes the book this way:

"The field of matching markets is, due to a unique confluence of circumstances, at the same time mature and yet in its infancy. Its birth goes back to the seminal 1962 paper of Gale and Shapley on stable matching. Over the decades, this field has become known for its highly successful applications, having economic as well as sociological impact. Its recent resurgence, with the revolutions of the Internet and mobile computing, has opened up altogether new avenues of research and novel, path-breaking applications. The distinctive feature of this book lies in treating this field in its true interdisciplinary spirit --- the field veritably sits at the intersection of economics, computer science, operations research and discrete mathematics, and this viewpoint has already led to a sequence of fundamental research results. Comprised of chapters written by over 50 top researchers, it still has the clarity, cohesiveness and organization of a textbook."

Oocyte ethics: financial compensation for human eggs

 New ethical guidance on egg donation, following an antitrust settlement regarding price fixing.

Financial compensation of oocyte donors: an Ethics Committee opinion.  by The Ethics Committee of the American Society for Reproductive Medicine, American Society for Reproductive Medicine, Birmingham, Alabama, Fertility and Sterility® Vol. 116, No. 2, August 2021

"Financial compensation of women donating oocytes for reproductive or research purposes is justified on ethical grounds and should acknowledge the time, inconvenience, and discomfort associated with screening, ovarian stimulation, oocyte retrieval, and postretrieval recovery and not vary according to the planned use of the oocytes or the number or quality of oocytes retrieved. This document replaces the document of the same name published in 2016. (Fertil Steril
2021;116:319-25. 2021 by American Society for Reproductive Medicine.)

"ESSENTIAL POINTS:

Financial compensation of women donating oocytes for reproductive or research purposes is justified on ethical grounds.

Compensation is in accord with principles of fairness, occurring within the framework of a professional relationship.

Compensation should acknowledge the donor’s time, inconvenience, and discomfort associated with screening, ovarian stimulation, oocyte retrieval, and postretrieval recovery. Compensation should not vary according to the planned use of the oocytes (reproductive or research) or the number or quality of oocytes retrieved.

Compensation should be fair and should not be an undue enticement that negatively impacts a donor’s ability to make an informed decision about the donation process and the risks involved with donation.

All oocyte-donor recruitment programs, including agencies, egg banks, and fertility clinics, should individually adopt and implement effective processes for information disclosure and counseling in order to promote informed decision-making by prospective donors.

Treating physicians owe the same professional duties to oocyte donors as to all other patients.

Programs should ensure equitable and fair provision of services to oocyte donors.

Programs should individually adopt and disclose policies regarding coverage of an oocyte-donor’s medical costs should she experience complications associated with the oocyte retrieval process."

...

" Because the burdens of donation are similar regardless of the ultimate use of the oocytes, compensating donors of oocytes for research is also ethically justified. There has been some movement at the state level to permit compensation to research donors, which stands in contrast to the approach articulated by the National Academy of Sciences with respect to compensation for oocyte donation for stem-cell research (21). In 2009, New York became the first US state to implement a policy permitting researchers to use public funds to reimburse women who donate oocytes directly and solely for stem-cell research, not only for the woman’s outof-pocket expenses, but also for the time, burden, and discomfort associated with the donation process (22). A law enacted in California in 2019 likewise requires women who provide human oocytes for research to be compensated for their time, discomfort, and inconvenience in the same manner as other research subjects, removing a previous prohibition of compensation of research donors (11).

...

"It is ethically permissible for a program to refuse to accept a prospective oocyte donor if they become aware that a prospective oocyte recipient or recruiting agency has offered gifts or payments that the program, in the exercise of its own ethical judgment, believes compromise the donor’s free choice or are otherwise ethically inappropriate. Programs should not assume that known donors, such as family or friends, are not being financially compensated. In one study of recipients using both known and anonymous donors, 19 of 20 of the known donors had been compensated, and there were no differences in the amounts provided to known and anonymous donors (27).

...

"This report was developed under the direction of the Ethics Committee of the American Society for Reproductive Medicine (ASRM) as a service to its members and other practicing clinicians. Although it reflects appropriate management of a problem encountered in the practice of reproductive medicine, it is not intended to be the only approved standard of practice or to dictate an exclusive course of treatment. Other plans of management may be appropriate, taking into account the needs of the individual patient, available resources, and institutional or clinical practice limitations.

Donating eggs for fertility: an update

Can it be made safe for drug users to call for help when a friend overdoses?

There are lots of ways that drug laws contribute to the design of the black market for drugs, and the behavior of its participants. Here's a recent post from the blog Bill of Health:

New Data Highlights Complexity of Good Samaritan Overdose Law Landscape, By David Momjian

 "To combat the rising death toll from drug overdoses, 47 state legislatures and the District of Columbia have passed Good Samaritan laws (GSLs) to protect bystanders from criminal prosecution if they call for medical assistance during a drug overdose. Bystanders to a drug overdose are often worried that by calling for help, they could be arrested for drug possession or evicted by the police, who often arrive first at the scene of a 911 call, even if it is a medical emergency.

A new dataset built by the Center for Public Health Law Research at Temple University’s Beasley School of Law and funded by Vital Strategies, covers the evolution of GSLs in the United States from January 1, 2007, to June 1, 2021."

Drug overdose deaths between April 2020 and 2021 reach 100,000

 The Washington Post has the story:

100,000 Americans died of drug overdoses in 12 months during the pandemic  By Dan Keating and Lenny Bernstein

"The U.S. drug epidemic reached another terrible milestone Wednesday when the government announced that more than 100,000 people had died of overdoses between April 2020 and April 2021. It is the first time that drug-related deaths have reached six figures in any 12-month period.

...

"The new data shows there are now more overdose deaths from the illegal synthetic opioid fentanyl than there were overdose deaths from all drugs in 2016."

We should be thinking about harm reduction...

John Morgan (1967-2021)

 Here's his obituary from Berkeley Haas, that I learned of only recently:

‘A giant of a person’: Economist John Morgan dies at 53 OCTOBER 29, 2021| BY LAURA COUNTS

"Professor John Morgan, an economist who found elegant new ways to analyze the world through the lens of game theory, and whose popular classes and sage mentorship made a deep impression on his students, passed away Oct. 6 at age 53. He died peacefully at his Walnut Creek home.

"During his nearly two decades at Berkeley Haas, Morgan left his mark through his prolific and wide-ranging research, his unconventional teaching that drew on strategy games he invented, and his generous leadership. He had been struggling with a painful autoimmune disease that put him on medical leave, but he continued with his research and had planned to resume teaching in the spring."

************

A paper of his that springs to mind is this one:

... plus shipping and handling: Revenue (non) equivalence in field experiments on ebay, by Tanjim Hossain and John Morgan, 2006, The B.E. Journal of Economic Analysis & Policy, https://doi.org/10.2202/1538-0637.1429

Abstract: Many firms divide the price a consumer pays for a good into two pieces---the price for the item itself and the price for shipping and handling. With fully rational customers, the exact division between the two prices is irrelevant---only the total price matters. We test this hypothesis by selling matched pairs of CDs and Xbox games in a series of field experiments on eBay. In theory, the ending auction price should vary inversely with the shipping charge to leave the total price paid constant. Contrary to the theory, we find that charging a high shipping cost and starting the auction at a low opening price leads to higher numbers of bidders and higher revenues when the shipping charge is not excessive. We show that these results can be accounted for by boundedly rational bidding behavior such as loss-aversion with separate mental accounts for different attributes of the price or disregard for shipping costs.

Freakonomics MD on deceased donor organs for transplants

 Freakonomics MD has a podcast focusing on the scarcity of deceased donor kidneys for transplant, and why recovered organs are sometimes discarded. They interview (separately) Dr. Sumit Mohan at Columbia, and me. (I was in fact interviewed by Jessica Wapner, not by the narrator, Dr. Bapu Jena, using a fancy microphone which they FedExed to me beforehand and I FedExed back to them afterwards...so my snippets probably sound like me...)

Market design course for health policy and medical students, at Stanford, taught by Alex Chan and Kurt Sweat

 Starting tomorrow, a short course in market design:

BIOS 203, Fall 2021: Market Design and Field Experiments for Health Policy and Medicine 

Primary Instructor: Alex Chan chanalex@stanford.edu | Office Hours: By appointment

Secondary Instructor: Kurt Sweat kurtsw@stanford.edu | Office Hours: By appointment

Description. Market design is an emerging field in economics, engineering and computer science about how to organize systems to allocate scarce resources. In this course, we study (1) the theory and practice of market design in healthcare and medicine, and (2) methods to evaluate the impact of such designs. Students will be provided with the necessary tools to diagnose the problems in markets and allocation mechanisms that render them inefficient, and subsequently develop a working toolbox to remedy failed markets and finetune new market and policy designs.

With a practical orientation in mind, we will learn how to construct rules for allocating resources or to structure successful marketplaces through successive examples in healthcare and medicine: medical residency matching, kidney exchange, allocation of scarce medical resources like COVID vaccine and tests, medical equipment procurement, online marketplace for doctors, and, if time permits, reward system for biopharmaceutical innovation. Guest lectures by practicing market designers and C-suite healthcare executives (CEO, CFO) would feature in the course as well.

An important goal of the class is to introduce you to the critical ingredients to a successful design: a solid understanding of institutions, grasps of economic theory, and well-designed experiments and implementation. In the final sessions, students will also learn how to design and deploy one of the most powerful tools in practical market design: A/B testing or randomized field experiments. These techniques are widely used by tech companies like UBER, Amazon, eBay, and others to improve their marketplaces.

At the end of the course, students should have acquired the necessary knowledge to become an avid consumer and user, and potentially a producer, of the market design and field experimental literature (recognized by 4 recent Nobel Prizes in Economics: 2007/2012/2019/2020).

Nervousness and confusion about residency applications

 Medpage Today has the story, which has been active on medical twitter for a while--some residency candidates are finding that their applications are incomplete, and blame the common application service ERAS, which in response reports that incomplete applications are the result of errors by the candidates.

Is ERAS Glitch Impeding Residency Interviews?  — Several students are missing letters of recommendation, but AAMC calls reports "unsubstantiated"

"MedPage Today spoke to several residency applicants who believe they experienced ERAS tech issues when submitting their applications. A majority of these applicants requested anonymity due to fear of retribution.

While many say a potential bug is not surprising, students are frustrated that they cannot pin down when "their documents went missing -- and whether or not it jeopardized their chances of matching with some programs.

"In each case, the glitch is almost identical: an applicant's letters of recommendation (or other documents) were uploaded to ERAS, and the applicant was certain they assigned the right materials to each program before they hit submit. But weeks later, applicants checked the platform to see that these documents had never been assigned nor delivered to the right programs -- rendering their applications incomplete."

Med Students Filed Nearly 70 Residency Applications Each— "I don't think this is sustainable at all" by Amanda D'Ambrosio, MedPage Today October 27, 2021

"Across all medical specialties, this cycle MD applicants submitted an average of 68 applications, DO applicants submitted 92, and international medical graduates submitted 139, according to data provided to MedPage Today by the Association of American Medical Colleges (AAMC).

"Medical graduates applying to orthopedic surgery in the 2022 cycle submitted an average of 88 applications -- the highest across all medical specialities. Candidates to urology, otolaryngology, and dermatology -- some of the most competitive specialties -- all applied to around 80 programs each.

"More than 46,000 medical graduates have applied for the 2022 residency match so far: approximately 23,000 MDs, 8,000 DOs, and 15,000 international graduates. The preliminary data from ERAS -- the centralized system that medical graduates use to apply to residency -- includes all applications submitted through the beginning of October."

Non-fungible tokens (NFTs), in Harvard Business Review, by Kaczynski and Kominers

 Can a new form of property rights created by blockchains also create valuable new kinds of markets? Or even communities?  

How NFTs Create Value, by Steve Kaczynski and Scott Duke Kominers, Harvard Business Review November 10, 2021

Summary.   How much could a cluster of pixels possibly be worth? More pointedly, why is it worth anything at all? The explosion of NFTs and their accompanying marketplaces have left many baffled, incredulous, and deeply skeptical. But while NFTs may be fetching eye-popping, eyebrow-raising valuations, there is a logic to how — and when — they create value. By creating a system of verifiable digital ownership NFTs fundamentally changed the market for digital assets, creating the possibility for new types of transactions. Amidst a flood of new ventures, however, it can be hard to tell which are creating value and which are just riding the hype. The companies that have been most successful on this new frontier have a few things in common: They make meaningful use of the NFT technology itself, leverage a community of users, generate confidence that they can continue executing on the project to maintain ongoing community engagement, offer accessible “on-ramps” for new users, and are able to weather crypto market swings.

...

"Many emerging NFT applications, meanwhile, are seeking to more explicitly blend online NFT ownership with offline use cases. A few restaurants, for example, have started using NFTs for reservations. And the ticketing industry has a major opportunity here: By issuing tickets as NFTs, venues can give a variety of benefits to purchasers, creating more of an incentive to buy, as well as providing the venues an opportunity to collect royalties on secondary sales.

"Other companies are exploring how NFTs could be used in establishing and recording people’s identity and reputation online. MIT recently started offering blockchain-based digital diplomas, which are effectively non-transferable NFTs. Meanwhile, both established players like Facebook (now Meta) and new ventures like POAP and koodos are providing ways for individuals to create and share NFTs around activities, affinities, and interests."

Blockchain job, with Sven Seuken, at Worldcoin

 Sven Seuken, a practical market designer for whom I have great respect, writes to ask that I advertise a job for a market designer.  Here is his email.

"I was wondering if you could advertise a market designer job on your blog. About six months ago, I have joined the Blockchain start-up Worldcoin (https://worldcoin.org/) and am now their Head of Economics and Chief Economist. We already have a team of six economists and computer scientists. But we are currently greatly expanding our team, looking for market designers, crypto economists, experimental economists, statisticians, etc., who are interested in developing practical incentive mechanisms that scale to more than a billion participants of the Worldcoin network. I believe that this is a fantastic opportunity for anyone interested in applying market design in practice. The positions are available on the junior and senior level, and they are available full-time or part-time. Anyone interested can contact me directly, or even better, directly apply here: https://worldcoin.org/job/4111358004

Counterbalancing Learning and Strategic Incentives in Allocation Markets by Kang, Monachou, Koren, and Ashlagi

 Here's a model with a new perspective on deceased organ waiting lists...

Counterbalancing Learning and Strategic Incentives in Allocation Markets by Jamie Kang, Faidra Monachou, Moran Koren, and Itai Ashlagi

Abstract: Motivated by the high discard rate of donated organs in the United States, we study an allocation problem in the presence of learning and strategic incentives.We consider a setting where a benevolent social planner decides whether and how to allocate a single indivisible object to a queue of strategic agents.  The object has a common true quality,  good or bad,  which is ex-ante unknown to everyone.  Each agent holds an informative, yet noisy, private signal about the quality.  To make a correct allocation decision the planner attempts to learn the object quality by truthfully eliciting agents’ signals. Under the commonly applied sequential offering mechanism, we show that learning is hampered by the presence of strategic incentives as herding may emerge. This can result in incorrect allocation and welfare loss. To overcome these issues, we propose a novel class of incentive-compatible mechanisms.  Our mechanism involves a batch-by-batch, dynamicvoting process using a majority rule. We prove that the proposed voting mechanisms improve the probability of correct allocation whenever agents are sufficiently well informed. Particularly, we show that such an improvement can be achieved via a simple greedy algorithm. We quantify the improvement using simulations.

The labor market that is the United States Marine Corps

 Armed forces around the world have some unique labor force problems, since by and large they do no lateral hiring...every senior officer was once a junior officer. (Doctors and lawyers are exceptions in the U.S. services--they can enter at a high rank without having spent years learning when and whom to salute...)  As we start to think about other specialties (e.g. cyber warriors, economic warriors), lateral hiring may become more important.  

A related problem faced by armed forces is retention: if all senior personnel have to be brought up through the system, it's especially costly to lose a (therefore) hard to replace, expensively trained operator.  Intelligent matching of people to positions is important for retention, particularly as they become more senior and have no further military service obligation (i.e. as their private sector opportunities become more salient).

The US Marines are thinking about this, and here's a recent report:

Talent Management 2030 November 2021, Department of the Navy, United States Marine Corps

Here are some highlighted snippets:

"The  core  objectives  of  all  modern  personnel  management  systems  are  to  recruit  individuals  with  the  right  talents,  match  those  talents  to  organizational  needs,  and  incentivize  the  most  talented and high performing individuals to remain with the organization"

"Our modern operational concepts and organizations cannot reach their full warfighting potential without a talent management system that recruits, develops, and retains the right Marines."

"Matching talents to duties maximizes performance."

"Incentives power the system."

"In this current era of heightened global competition, the Marine Corps requires a vehicle for rapidly recruiting mature, seasoned experts. We can no longer afford the cost in time – measured in years, and sometimes decades – to train and educate all our technical leaders, particularly given the extraordinary pace of technological change."

"We should have an open door for exceptionally talented Americans who wish to join the Marine Corps, allowing them to laterally enter at a rank appropriate to their education, experience, and ability."

"For Marines, a talent marketplace will increase available information about billet openings, improve transparency, and provide individuals with far greater influence over their future assignments."

"A talent management system relies on incentives, not coercion. While the needs of the Marine Corps are always paramount, we cannot afford to push the most talented young officers out the door after investing years in their leadership development, education, and training. "

The labor market that is the military: a report from the National Academies of Science, Engineering, and Medicine

Marijuana black markets are coexisting with (poorly designed, over-regulated, highly taxed) legal markets in California

 The Guardian has the story:

California legalized weed five years ago. Why is the illicit market still thriving? by Amanda Chicago Lewis

"Voters passed a law in November 2016 making recreational marijuana legal. But today, the vast majority of the market remains underground – about 80-90% of it, according to experts.

"Because that 2016 law, known as Proposition 64, gave municipalities the power to ban weed as they see fit, the majority of cities and counties still don’t allow the sale of cannabis, inhibiting the growth of the legal market.

"In the places that do allow pot shops and grows, business owners say high taxes, the limited availability of licenses, and expensive regulatory costs have put the legal market out of reach. 

...

"The story of California’s legal weed chaos dates back to 1996, when voters passed a law allowing medical marijuana. At the time, Bay Area Aids activists saw the way pot relieved pain and stimulated hunger among their emaciated and desperately ill friends. That led to a grassroots campaign to get Proposition 215, a measure legalizing the medical use of cannabis, on the California ballot.

"However, Prop 215 only allowed doctors to recommend that patients and their caregivers grow their own weed. Essentially, it legalized a commodity without legalizing the business side of it.

"For the next 20 years, a laissez-faire, gray market for medical marijuana flourished and became entrenched. With doctors’ recommendations for medical marijuana easy and cheap to come by, cannabis entrepreneurs practiced a lucrative form of civil disobedience, opening dispensaries, manufacturing edibles and growing acres of plants that brought in enough money to offset intermittent law enforcement crackdowns. The industry developed protocols to get a business back up and running right after a raid, such as keeping cash offsite and obscuring ownership through a series of management companies.

"If you could withstand the legal uncertainty, it was a good time to make money in marijuana. By 2010, the city of Los Angeles had about 2,000 pot shops illegally selling cannabis. Statewide, the total illicit market surged, causing Mexican cartels to either stop growing weed or to relocate their grows to California.

...

"For a marijuana enterprise today, becoming legal has often meant sacrificing a good deal of profit. Businesses frequently pay an effective tax rate of 70%, in part because they are breaking federal law and therefore aren’t able to take tax deductions, but also because politicians see the industry as a source of tax revenue and set higher rates.

...

"But the longer we allow cannabis to remain state-legal and federally illegal, the harder it will be to fix. Though botching weed legalization sounds like a trivial issue, it intersects with many of the issues that are fundamental to our lives, from criminal justice to public health, gang violence to economic inequality, the opioid crisis to the wellness craze. Cannabis is the second-most-valuable crop in the country, after corn and ahead of soybeans. It’s the most common reason for arrest in America. And despite marijuana’s dubious reputation, research has shown the plant “may have therapeutic potential in almost all diseases affecting humans”.

Approximating large games

One of the big lessons of market design is that market participants may have big strategy sets.  This means that analyzing naturally occurring strategic settings may exceed our ability to model and analyze them as fully specified games.

Here's a paper that explores an interesting, somewhat related idea:

Christian Kroer, Alexander Peysakhovich, Eric Sodomka, Nicolas E. Stier-Moses (2021) Computing Large Market Equilibria Using Abstractions. Operations Research, Articles in Advance 01 Oct 2021, https://doi.org/10.1287/opre.2021.2163

"Abstract. Computing market equilibria is an important practical problem for market design, for example, in fair division of items. However, computing equilibria requires large amounts of information (typically the valuation of every buyer for every item) and computing power. We consider ameliorating these issues by applying a method used for solving complex games: constructing a coarsened abstraction of a given market, solving for the equilibrium in the abstraction, and lifting the prices and allocations back to the original market. We show how to bound important quantities such as regret, envy, Nash social welfare, Pareto optimality, and maximin share/proportionality when the abstracted prices and allocations are used in place of the real equilibrium. We then study two abstraction methods of interest for practitioners: (1) filling in unknown valuations using techniques from matrix completion and (2) reducing the problem size by aggregating groups of buyers/items into smaller numbers of representative buyers/items and solving for equilibrium in this coarsened market. We find that in real data allocations/prices that are relatively close to equilibria can be computed from even very coarse abstractions."
