Course allocation with minimum quotas, by Bichler, Hammerl, Waldherr, and Morrill

Here's a course allocation problem:, "Our specific task was to assign students to classes in the computer science and information systems department at the Technical University of Munich, a large European university. This department is currently the largest department at the university with more than 6,000 students."

How to Assign Scarce Resources Without Money:  Designing Information Systems that are Efficient, Truthful, and (Pretty) Fair
Martin Bichler, Alexander Hammerl, Stefan Waldherr,  Thayer Morrill
INFORMATION SYSTEMS RESEARCH, forthcoming.

"Matching with preferences has great potential to coordinate the efficient allocation of scarce resources in organizations when monetary transfers are not available, and thus can provide a powerful design principle for information systems. Unfortunately, it is well-known that it is impossible to combine all three properties of truthfulness, efficiency, and fairness (i.e. envy-freeness) in matching with preferences. Established mechanisms are either efficient or envy-free, and the efficiency loss in envy-free mechanisms is substantial. We focus on a widespread representative of a matching problem: course assignment where students have preferences for courses and organizers have priorities over students. An important feature in course assignment is that a course has both a maximum capacity and a minimum required quota. This is also a requirement in many other matching applications such as school choice, hospital-residents matching, or the assignment of workers to jobs. We introduce RESPCT, a mechanism that respects minimum quotas and is truthful, efficient, and has
low levels of envy. The reduction in envy is significant and is due to two remarkably effective heuristics. We follow a design science approach and provide analytical and experimental results based on field data from a large-scale course assignment application. These results have led to a policy change and the proposed assignment system is now being used to match hundreds of students every semester."

Strategy proofness in auctions, beyond the frontiers of our most reliable knowledge

A lot of market design goes on beyond the frontiers for which we have robust general theorems. Computational methods are important in these cases (and sometimes the theory follows along eventually).   Here's a recent auction paper on archiv.org that sheds some light on strategy proofness.

Certifying Strategyproof Auction Networks
Michael J. Curry∗ Ping-Yeh Chiang∗ Tom Goldstein and  John P. Dickerson
 
Abstract: Optimal auctions maximize a seller’s expected revenue subject to individual rationality and strategyproofness for the buyers. Myerson’s seminal work in 1981 settled the case of auctioning a single item; however, subsequent decades of work have yielded little progress moving beyond a single item, leaving the design of revenue-maximizing auctions as a central open problem in the field of mechanism design. A recent thread of work in “differentiable economics” has used tools from modern deep learning to instead learn good mechanisms. We focus on the RegretNet architecture, which can represent auctions with arbitrary numbers of items and participants; it is trained to be empirically strategyproof, but the property is never exactly verified leaving potential loopholes for market participants to exploit. We propose ways to explicitly verify strategyproofness under a particular valuation profile using techniques from the neural network verification literature. Doing so requires making several modifications to the RegretNet architecture in order to represent it exactly in an integer program. We train our network and produce certificates in several settings, including settings for which the optimal strategyproof mechanism is not known

Pandemic policies work differently in different places

Here's a recent largely empirical paper by many authors, looking at the actual and counterfactual impact of different pandemic responses in different cities, with the aim (among others) of mapping the employment/mortality frontier of different policies.  They build on GPS and payment data for modeling movement and interpersonal contact, and electronic health records for hospitalization and deaths.  Thus, for example, they find that in Chicago, different policies can make big moves along the employment/mortality frontier (allowing only essential workers to go to work reduces deaths and increases unemployment, both by a lot), while in a more sparsely inhabited city like Sacramento, it's hard to change the mortality rate (but only allowing essential workers still causes lots of unemployment).

Socioeconomic Network Heterogeneity and Pandemic Policy Response
Mohammad Akbarpour, Cody Cook, Aude Marzuoli, Simon Mongey, Abhishek Nagaraj, Matteo Saccarola, Pietro Tebaldi, Shoshana Vasserman, Hanbin Yang
NBER Working Paper No. 27374
Issued in June 2020

Abstract: "We develop a heterogeneous-agents network-based model to analyze alternative policies during a pandemic outbreak, accounting for health and economic trade-offs within the same empirical  framework. We leverage a variety of data sources, including data on individuals' mobility and encounters across metropolitan areas, health records, and measures of the possibility to be productively working from home. This combination of data sources allows us to build a framework in which the severity of a disease outbreak varies across locations and industries, and across individuals who differ by age, occupation, and preexisting health conditions.

"We use this framework to analyze the impact of different social distancing policies in the context of the COVID-19 outbreaks across US metropolitan areas. Our results highlight how outcomes vary across areas in relation to the underlying heterogeneity in population density, social network structures, population health, and employment characteristics. We find that policies by which individuals who can work from home continue to do so, or in which schools and firms alternate schedules across different groups of students and employees, can be effective in limiting the health and healthcare costs of the pandemic outbreak while also reducing employment losses."

Market designers and ventilator allocation, by Pathak, Sönmez, and Ünver

I recall when a big part of practical market design was explaining to skeptical listeners why they should listen to economists...

June 19, 2020
Improving Ventilator Rationing Through Collaboration With Experts on Resource Allocation
Parag A. Pathak, PhD1; Tayfun Sönmez, PhD2; M. Utku Ünver, PhD2
JAMA Netw Open. 2020;3(6):e2012838. doi:10.1001/jamanetworkopen.2020.12838

"In our study of ventilator rationing guidelines,2 we have not seen task forces include input from experts on market design, a field of economics that studies the allocation of scarce resources. In many settings, price plays a central role in allocation when demand exceeds supply; however, this instrument is often not available in public health emergencies with extreme scarcity. During the last 2 decades, substantial research activity and policy developments have taken place regarding allocation environments where price-based tools are either unavailable or considered repugnant. Two noteworthy examples are the organization of kidney exchanges in the US and the assignment of seats at public schools. Because research in market design incorporates ethical considerations and operationalizes these objectives with an allocation mechanism, scholars in this field can be valuable for transforming various trade-offs between ethical principles into specific allocation procedures."

Curbside interviewing / hiring joins curbside pickup in a social-distancing economy

The WSJ has the story:

Job Recruitment Adopts Social Distancing as Coronavirus Alters Practices
Employers rethink how they hire, trying remote onboarding and curbside job fairs to reduce risks
By James T. Areddy, June 22, 2020

"During the parking-lot screening, the couple and other job seekers sat in their cars and provided recruiters, wearing face masks, with basic information for possible callbacks on a range of jobs in light industry and those requiring skilled labor.

"It is an example of how social distancing, needed to stem the coronavirus pandemic, is altering job recruitment."

I join the NRMP board of directors

In the 1990's I worked closely with the NRMP on the resident match, and since then I've been following it from a distance.  Now I'll join their Board.  I imagine that during my term there may be an opportunity to look at how the overall system of applications, interviews and matching have co-evolved and adapted to each other.

Here's the NRMP press release:

 NRMP Board Of Directors Welcomes Outstanding Cohort Of New Members
Nobel Prize Recipient Dr. Alvin E. Roth Among Talented Slate of Elected Individuals
Washington, D.C., June 22, 2020 –

At its June meeting, the National Resident Matching Program® (NRMP®) Board of Directors elected five individuals for terms that begin July 1, 2020. The NRMP’s 19-member Board includes medical school deans, institutional officials, clinical program directors, resident/fellow physicians, medical students, and one public member. The appointment of Dr. Alvin E. Roth, the 2012 co-recipient of the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, highlights the quality of the slate of new members.

“The individuals recently elected to the NRMP Board of Directors will bring an impressive mix of professional experiences and fresh perspectives to the governance of the organization,” said NRMP Board Chair Dr. Steven J. Scheinman. “They were selected from a deep pool of accomplished applicants, and we look forward to working with them on an array of initiatives.”

The term for directors is four years, with a maximum of two terms. The term for resident/fellow and student directors is two years. Listed alphabetically, the new members include:

Ricardo J. Boccardo Bello, M.D., General Surgery resident at the University of Massachusetts Medical School. A graduate of the Universidad Central de Venezuela in Caracas, he earned a Master of Public Health from the London School of Hygiene and Tropical Medicine and completed his PGY-1 General Surgery residency and postdoctoral research fellowship in Microsurgery Outcomes at Johns Hopkins University. While at Johns Hopkins, he received the Core Surgery Clerkship Outstanding Junior Resident Teaching Award.

Sydney Miller, Michigan State University College of Osteopathic Medicine student. Elected President of her class, Ms. Miller serves alongside faculty leaders as a member of the Dean’s Executive Board, which deliberates the college’s undergraduate and graduate medical education programs and other strategic initiatives. She earned her undergraduate degree in Human Biology at Michigan State University. Her interests include increasing awareness and appreciation of osteopathic medicine.

Alvin E. Roth, Ph.D., Senior Fellow at the Stanford Institute for Economic Policy Research and a Professor, by courtesy, for the school of Management Science and Engineering. He is also the George Gund Professor of Economics and Business Administration Emeritus at Harvard University. Dr. Roth’s academic expertise is in game theory, experimental economics, and market design, and he was co-recipient of the 2012 Nobel Prize in Economics for work which focused in part on the NRMP’s matching algorithm. He earned a doctoral degree in Operations Research from Stanford University.

Morgan Swanson, M.D./Ph.D. student at the University of Iowa Carver College of Medicine and College of Public Health. She has served with the Association of American Medical Colleges’ Organization of Student Representatives (OSR), most recently as one of 12 students selected to its Administrative Board. Ms. Swanson graduated from Iowa State University and serves as a member of the Editorial Board of the U.S. Centers for Disease Control and Prevention’s Morbidity and Mortality Weekly Report.

Who are U.S. essential workers in the coronavirus lockdowns? McCormack, Avery, Spitzer and Chandra in JAMA

Here's a paper in JAMA that focuses on households with essential workers, many of whom are low income.   40% of adult workers are classified as essential workers, and a quarter of them earn less than $40,000.

McCormack G, Avery C, Spitzer AK, Chandra A. Economic Vulnerability of Households With Essential Workers. JAMA. Published online June 18, 2020. doi:10.1001/jama.2020.11366

"We analyzed data from the Public Use Microdata Sample of the 2018 American Community Survey (ACS). The US Census Bureau chooses a random sample of US addresses each month, contacts selected households by mail, and follows up by phone and personal visit to address nonresponse.3 The Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency (CISA) released an “Essential Critical Infrastructure Workforce” advisory list of occupations necessary to “continuity of functions critical to public health and safety” in March 2020 and updated that list in April 2020.4 We matched industry and subindustry codes in the ACS to the 6-digit Standard Occupation Codes (indexed by the US Bureau of Labor Statistics) in the CISA advisory list to identify essential workers.5 We assessed the proportion and demographic characteristics (age, sex, race as given in response to a multiple-choice question) of essential workers by industry."

"Eight of the 21 industry categories from the ACS accounted for 73% of essential workers. Health care accounted for a larger proportion (15%) of essential workers than any other industry: 65% of health care workers held essential jobs. Black individuals were overrepresented in several essential industries, notably transportation (23%), public administration (18%), and health care (18%).

"A total of 1 410 976 households were represented in the 2018 ACS with an estimated 51% of those households including an essential worker. Table 2 summarizes household characteristics of essential workers: 25% of essential workers were estimated to have low household income, 18% to live in a household with at least 1 uninsured person, and 18% to live with someone 65 years or older. We estimated that 48% of essential workers lived in a household with at least 1 risk and 13% of essential workers lived in high-risk households."

Supermarkets

There's a nice article about supermarkets in the Atlantic, and how they are organized and supplied,  motivated by nostalgia for one NYC chain, Fairway, that is now going through bankruptcy.

The Pandemic Shows Us the Genius of Supermarkets
A short history of the stores that—even now—keep us supplied with an abundance of choices
by Bianca Bosker

"Most stores open with a colorful bounty of flowers and produce (a breath of freshness to whet our appetites), followed by the flyover expanse of the center store (cans, jars, boxes, bags), followed, in the way back, by milk, eggs, and other staples (pushed to Siberia so you’ll travel through as much of the store as possible, and be tempted along the way). Store designers can choose from a variety of floor plans—forced-path, free-flow, island, wagon-wheel—but by far the most popular is the combination grid/racetrack, with nonperishable items in rectilinear aisles, and the deli, cheese, meat, seafood, and produce departments circling them on the exhilaratingly named racetrack, so called because we scoot faster on the store’s perimeter.

Here's an earlier story on how and why established retail chains (low debt, own their own real estate) attract the interest of private equity firms:

The UpFront market for television ads: is it time to change its timing?

The coronavirus pandemic is an opportunity for advertisers and television networks to renegotiate an odd feature of their market for advertisements.  As I understand it, advertisers wishing to purchase blocks of advertising for Fall television series have to do so early, in the Spring, in what is called the upfront market.  This runs so early that some of the shows are still in the early planning stage, so that advertisers have some descriptions of plot lines and target demographics, but they are buying ads in shows that no one has seen yet.

The WSJ has the story:

Big Advertisers Call for a Seasonal Time-Shift in TV’s Upfront Marketplace
Procter & Gamble, Bank of America and others want to move upfront negotiations for ads in the multibillion TV market to the fall from the spring.  By Sahil Patel

"Big-brand advertisers and an industry trade group are calling on the television networks to delay their annual upfront ad marketplace to later in the year—a big shift in the way TV programmers and advertisers have done business for decades.

"The push is driven in part by the havoc the coronavirus has caused in the television business, from the shutdown of production to the big question mark over when sports will return. Both are critical to advertisers: they say there is a lack of visibility into what they would be buying. Ad budgets also are in flux as many advertisers have pared spending during the recent downturn. Many are struggling to figure out what next year’s budgets will look like.
...
"The TV industry has operated on a broadcasting and advertising calendar that starts in September since 1962, when ABC decided to debut all its programs after Labor Day. Normally, TV networks pitch their new programming at glitzy New York City events in the spring and negotiate ad deals for the fall season soon after.

This year, however, the live upfront events were canceled due to the virus, and executives now expect deal-making will drag out through the year.
...
"The trade group said there is still value in negotiating ad deals upfront—they would just prefer to shift the timeframe. Upfront deals are beneficial to advertisers as they are able to get lower prices, especially with a limited supply of inventory, and maintain protections like make-goods—which aren’t available to advertisers buying in the “scatter” market, when ads are purchased closer to the time they air."

Nicola Lacetera, on The Ethics and Economics of Paying Plasma Donors

Nicola Lacetera is among the leaders in studying public views about compensating donors of various sorts. Here he discusses the plasma supply, which is particularly timely given the growing availability of convalescent plasma for Covid-19. (30 minutes)

Peter Jaworski on The Case for Voluntary Remunerated Plasma Collections

Peter Jaworski makes the case for allowing compensation of plasma donors in the wealthy nations of the British Commonwealth:

Bloody Well Pay Them: The Case for Voluntary Remunerated Plasma Collections
BY PETER JAWORSKI JUNE 14, 2020

Here's the executive summary ( a long summary of a long paper):

"•Blood plasma is used in a wide, and growing, range of life-saving therapies. It is now being trialled to treat Covid-19, including by the United Kingdom’s National Health Service.

• There are significant global shortages of blood plasma. Demand is growing at a rate of 6-10% per year. Three-quarters of people do not have access to the appropriate plasma therapy, largely outside of developed countries.
• Shortages are significantly exacerbated by the World Health Organisation’s policy — adopted by the United Kingdom, Australia, New Zealand and some Canadian provinces — to rely exclusively on Voluntary Non-Remunerated Blood Donations (VNRBD).
• The United Kingdom imports 100% of its supply of blood plasma, Canada (84%), Australia (52%), and New Zealand (13%). They are increasingly dependent on imports for blood plasma from countries that remunerate donors. This inflates the global blood plasma price, making it unaffordable for low to middle income countries.
• The United States, which allows remuneration of donors, is responsible for 70% of the global supply of plasma. Together with other countries that permit a form of payment for plasma donations — including Germany, Austria, Hungary, and Czechia —they account for nearly 90% of the total supply. The dependence on a small number of countries is a serious health security threat.
• Non-remunerated donations are estimated to be 2-4 times more expensive than remunerated collections, because of the expense of recruiting and retaining donors, including through marketing. Australia, for example, could save $200 million annually by importing all blood plasma.
• There are significant global shortages of plasma therapies. The growing global demand cannot be met without remuneration.
• The evidence is clear that remunerating individuals for blood plasma donations is safe, would ensure a secure supply of plasma, does not discourage non-remunerated blood donations, and would provide significant patient benefits, including peace of mind.
• In order to ensure a safe, secure, and sufficient supply of plasma therapies, the United Kingdom, Canada, Australia, and New Zealand should adopt Voluntary Remunerated Plasma Collections (VRPC):
• VRPC means individuals are paid, in cash or in-kind, to give plasma of their own free will. It also means collections using modern deferral and testing techniques, such as deferring higher-risk donors and advanced viral detection tests.
• VRPC would allow the Canzuk countries to at the very least become self-sufficient, and potentially contribute to the humanitarian goal of increasing the global supply of blood plasma for low to middle income countries."

Here's a description of the historical setting:

"On June 11, 2009, the World Health Organization (WHO) issued “The Melbourne Declaration on 100% Voluntary Non-Remunerated Donation of Blood and Blood Components.”  The Declaration was a re-commitment to, what they call, “Voluntary Non-Remunerated Blood Donations” or VNRBD,” as well as to World Blood Donor Day, celebrated every June 14th.  The Declaration set a target date for achieving 100% VNRBD in safe, secure, and sufficient blood and blood products, including plasma-derived medicinal products. That target date was 2020.
...
"This year will end without a sufficient supply of plasma based on 100% non-remunerated plasma collections, neither will 2030. With each passing year from 2009 to the present, the world has moved further from that target, and closer to being nearly entirely dependent on the United States."

*******

Before publishing the paper, Jaworski solicited some supportive quotes to use as blurbs.  Here's mine:

Nobel Prize winning economist Alvin Roth says of the current over-reliance on the US’ paid donor market:
“I find confusing the position of some countries that compensating domestic plasma donors is immoral, but filling the resulting shortage by purchasing plasma from the U.S. is ok.”

Vic Fuchs considers healthcare organization going forward, in JAMA

Vic Fuchs has a lot of insight into American healthcare. Here are his proposals for after the pandemic (or perhaps for a new administration in Washington). It is worth reading it all (I'm just excerpting some lines...)

Health Care Policy After the COVID-19 Pandemic
Victor R. Fuchs, JAMA.  June 12, 2020. doi:10.1001/jama.2020.10777

"This is a time to think more boldly about the future of the US health care system. The health care system is dysfunctional for many individuals in the US; it is too costly, too unequal, and too uncertain in its eligibility and coverage, with an increasing number of uninsured. ... In exploring the challenges and difficulties ahead, it is useful to distinguish between those that are primarily technical issues (although these are not exempt from politics) and those that are political obstacles to significant reform

...[Technical issues:]

"how to raise the nearly $4 trillion each year to pay for US health care; and how to organize and deliver the care and compensate those who provide it. The experience of other high-income countries indicates that the most efficient and equitable method to finance universal coverage is through a flat tax on consumption, such as a value-added tax, collected from businesses but passed on to consumers via higher prices.1 An alternative is a retail sales tax, which is more cumbersome and costly to collect than a value-added tax, but makes the connection between the tax and health insurance more apparent to the public.

"Those who object to a flat tax (the same rate for everyone) because they think it is not progressive are mistaken. High-income individuals pay more because they consume more, but everyone gets similar health insurance regardless of income. The combination of the tax and the insurance is quite progressive. If it were not, left of center governments in the Organization for Economic Cooperation and Development would not eagerly embrace a value-added tax. In contrast, employment-based insurance sets essentially the same price for any given policy regardless of income. High-income individuals only pay more if they choose a more expensive policy, but that does not help pay for care for low-income or unemployed individuals.

...[Political issues:]

"Distrust of the government is difficult to dispel, but it is possible to do so as President Roosevelt proved with his New Deal reforms in the 1930s. Even though it has seemed that major reform of health care would only occur in the wake of a major war, a depression, or large-scale civil unrest that changed the political balance, it now appears that the COVID-19 pandemic may provide the dynamic for major political change.8 If that occurs, major health care reform will be more attainable."

Paul Milgrom corrects the record on spectrum auctions and market design

Paul Milgrom responds in detail to some scurrilous online criticisms and innuendos about market designers in general and spectrum auctions in particular.

 The Market Design Community and the Broadcast Incentive Auction: 
Fact-Checking Glen Weyl’s and Stefano Feltri’s False Claims
By Paul Milgrom*  June 3, 2020 (and republished on Digitopoly on June 14)

"In a recent Twitter rant and a pair of subsequent articles in Promarket, Glen Weyl [1] and Stefano
Feltri [2] invent a conspiratorial narrative according to which the academic market design community is secretive and corrupt, my own actions benefitted my former business associates and the hedge funds they advised in the 2017 broadcast incentive auction, and the result was that far too little TV spectrum was reassigned for broadband at far too little value for taxpayers.
The facts bear out none of these allegations. In fact, there were:

• No secrets: all of Auctionomics’ communications are on the public record,
• No benefits for hedge funds: the funds vigorously opposed Auctionomics’ proposals, which reduced their auction profits,
• No spectrum shortfalls: the number of TV channels reassigned was unaffected by the hedge funds’ bidding, and
• No taxpayer losses: the money value created for the public by the broadband spectrum auction was more than one hundred times larger than the alleged revenue shortfall.

They have some very interesting ideas about organizing what are called "watch parties" in the program, but those are in flux, and they didn't give me permission to describe their current thoughts.

Update (embargo lifted): Jason Hartline sends these links to explain:
Philosophy: http://ec20.sigecom.org/participation/covid/

Tech details: http://ec20.sigecom.org/tech/

Earlier, Nicole Immorlica had explained this way:

"In the first hour of the watch party, we will have 3-5 parallel sessions of one hour each. In each of these, we will play three 20 min pre-recorded talks with the authors present to answer questions during the talk via chat. "In the second hour, all papers from all parallel sessions will enter a virtual poster room. Participants each control an avatar and will "walk around" the virtual room. When they get close to a poster, they can view it. When they get close to the poster presenter or another participant, that person's video enters their view and they can talk. There will also be a video steam of one minute lightening talks for the posters in one corner of the virtual room in case you want a quick recap of a talk you missed. "We're also trying to innovate around coffee breaks, having hosted conversations with a limited number of participants on a first come, first serve basis, and other activities (these are not fully formed ideas yet)." 

Kidney exchanges and Shapley values

Here's a paper aimed at thinking about kidney exchange cooperation among European national kidney exchange programs. The Shapley value here is applied to countries (not to patient-donor pairs as in some U.S. proposals), and the aim is to measure fairness of allocations with reference to Shapley values.


COMPENSATION SCHEME WITH SHAPLEY VALUE FOR MULTI-COUNTRY KIDNEY EXCHANGE PROGRAMMES
Peter Biro, Xenia Klimentova Joao Pedro Pedroso Marton Gyetvai  William Pettersson Ana Viana

ABSTRACT: Following up the proposal of (Klimentova, Viana, Pedroso and Santos 2019), we  consider the usage of a compensation scheme for multi-country kidney exchange programmes to balance out the benefits of cooperation.  The novelty of our study is to base the target solution
on the Shapley value of the corresponding TU-game, rather than on marginal contributions. We compare the long term performances of the above two fairness concepts by conducting simulations on realistically generated kidney exchange pools.

Tools to allocate medical supplies in a crisis: Cramton, Ockenfels, Roth and Wilson in Nature

Publishing a commentary in Nature is a dizzying process for anyone accustomed to the stately dance of publishing in Economics.  It's fast (in this case the commentary below appeared one month after submission), and the editors play an active role.

Borrow crisis tactics to get COVID-19 supplies to where they are needed
Emergency procedures that keep electricity running and food banks stocked can also keep health workers in protective equipment.
Peter Cramton, Axel Ockenfels, Alvin E. Roth and Robert B. Wilson
Nature 582, 334-336, 11 JUNE 2020 doi: 10.1038/d41586-020-01750-6

We began thinking about what market designers know about addressing shortages in an emergency.  We considered the experience in electricity markets and food banks as potentially relevant.
Here are some of our early notes:

• Selling to the highest bidder isn’t always acceptable in an emergency (repugnance)
• But prices matter, because they help generate new supply and reduce excessive  precautionary demand
• And prices can do some of their work even if just in specialized accounting money, so that we’re not just sending supplies to the wealthiest institutions
• Coordination is needed; centralized clearinghouses can help.
• It would have been useful to have had a sufficiently centralized clearinghouse operating as an ordinary market exchange in normal times, that could go into emergency mode when required (so that new suppliers and demanders would have had an address to go to to take part in newly formed supply chains...)
• Our experience in this regard now (after wave 1 of COVID-19) should inform how we think about these markets in the near future (wave 2, next winter, etc.) and the further future (future pandemic diseases...)
• In some respects Germany may be better poised to take steps towards a centralized clearinghouse than we are in the decentralized U.S., especially given our current political disarray. (But Germany has politics of its own...)
• It will be worthwhile to think more about the design of markets that are robust against emergencies –  so they can transition gracefully from normal to emergency states, and back.

The pandemic market for disinfectants (including Bourbon scented hand sanitizer)

Disinfectants, particularly those used in medical settings, are regulated, both to make sure that they are effective at disinfecting, and to make sure that they don't have negative (e.g. toxic) properties on people or animals or households.

The OECD summarizes the situation in a few countries from (in alphabetical order) Australia to the United States:

Emergency responses for the supply of disinfectants against Covid-19

Some further information is available on the website of the European Chemicals Agency (ECHA)

Some regulatory processes have been speeded up during the covid-19 pandemic, to allow new entrants into the market to relieve shortages.  One consequence of that is that, in the U.S. you can now buy bourbon-scented hand sanitizer, from bourbon distilleries in Kentucky and elsewhere:

Laws and law enforcement for actions whose illegality is controversial (the case of 'honor killing')

Repugnant transactions and actions are sometimes banned with the full force of the law: consider  e.g. narcotics trafficking in the U.S., where our prisons are full of people convicted of drug crimes.   But sometimes, a legal ban comes with just a slap on the wrist: e.g., also in the U.S., prostitution is illegal almost everywhere, but mostly treated as a misdemeanor, not a serious crime. 

The punishment may not always fit the crime, but it tells us something about how legislators view the seriousness of the crime. 

So I was struck by the first sentences of this NY Times story about an "honor killing" in Iran:

A Daughter Is Beheaded, and Iran Asks if Women Have a Right to Safety
The so-called honor killing of a 14-year-old girl in Iran has shaken the country and forced an examination of its failure to protect women and children.

"Before he beheaded his 14-year-old daughter with a farming sickle, Reza Ashrafi called a lawyer.

"His daughter, Romina, was going to dishonor the family by running off with her 29-year-old boyfriend, he said. What kind of punishment, he asked the lawyer, would he get for killing her?

"The lawyer assured him that as the girl’s guardian he would not face capital punishment but at most 3 to 10 years in jail, Mr. Ashrafi’s relatives told an Iranian newspaper.

"Three weeks later, Mr. Ashrafi, a 37-year-old farmer, marched into the bedroom where the girl was sleeping and decapitated her.
