I was asked by the LATimes to contribute to a panel on economic and pandemic policy. The other contributors are Joseph E. Stiglitz, Christina Romer, Alicia H. Munnell, Jason Furman, Anat R. Admati, James Doti, Simon Johnson, Ayse Imrohoroglu and Shanthi Nataraj. Here’s my contribution:
If an invader rained missiles down on cities across the United States killing thousands of people, we would fight back. Yet despite spending trillions on unemployment insurance and relief to deal with the economic consequences of COVID-19, we have spent comparatively little fighting the virus directly.
Testing capacity has slowly increased, but where is the national program to create a dozen labs each running 200,000 tests a day? It’s technologically feasible but months into the crisis, we have only just begun to spend serious money on testing.
We haven’t even fixed billing procedures so we can use the testing capacity that already exists. That’s right, labs that could be running tests are idle because of billing procedures. And while some parts of our government are slow, the Food and Drug Administration seems intent on reducing America’s ability to fight the virus by demanding business-as-usual paperwork.
Operation Warp Speed is one of the few bright spots. Potential vaccines often fail and so firms will typically not build manufacturing capacity, let alone produce doses until after a vaccine has been approved. But if we follow the usual procedure, getting shots in arms could be delayed by months or even years.
Under Operation Warp Speed, the government is paying for capacity to be built now so that the instant one of 14 vaccine candidates is proven safe and effective, production will be ready to go. That’s exactly what Nobel-prize winning economist Michael Kremer, Susan Athey, Chris Snyder and I have recommended. It might seem expensive to invest in capacity for a vaccine that is never approved, but it’s even more expensive to delay a vaccine that could end the pandemic.
Relief payments can go on forever, but money spent on testing and vaccines has the potential to more than pay for itself. It’s time to fight back.

My point about not fighting the virus directly was illustrated by many of the other panelists. Joseph Stiglitz, Christina Romer, Alicia Munnell, Jason Furman, James Doti, and Shanthi Nataraj say nothing or next to nothing about viruses. Only Anat Admati, Simon Johnson, Ayse Imrohoroglu get it.
Admati supports a Paul Romer-style testing program:
Until effective vaccines and therapies are available, which may be many months away, our best approach is to invest heavily in increasing the capacity for testing many more people and isolating those infected.
Simon Johnson argues, in addition, for antibody tests (not the usual PCR tests):
Policymakers should go all-in on ramping up antibody testing, to determine who has been exposed to COVID-19. Such tests are not yet accurate enough to determine precise immunity levels, but the work of Michael Mina, an immunologist and epidemiologist at Harvard, and others demonstrates that using such tests in the right way generates not just information about what has happened but, because of what can be inferred about underlying disease dynamics, also the information we need to understand where the disease will likely next impact various local communities.
Imrohoroglu advocates for targeted lockdown:
In addition to CDC recommendations about social distancing and public health strategies for all, I believe that as we reopen, we should keep a targeted lockdown policy in place for at-risk groups.
Moral hazard — forget about it!:
In the Mediterranean island nation of Cyprus, government leaders have pledged to cover all costs for any traveler who tests positive for the coronavirus while on vacation, according to the Associated Press. In a letter sent out to governments, airlines and tour operators, Cypriot officials said they would cover “lodging, food, drink and medication for covid-19 patients and their families” while on the island.
Tourism accounts for 13 percent of Cyprus’s economy, according to the AP, and with one of the lowest coronavirus ratios per capita in Europe, tourism ministers plan to restart international air travel on June 9.
Here is the full story, which includes other examples.
From my email:
I saw your post about COVID blood brokers–My girlfriend and I had it in March and finally got antibody tests last week when the city opened the free clinics.
I inquired on a national plasma donor site, was directed to CSL Plasma in Clifton NJ, and a donor concierge from LeapCure reached out. They didn’t tell me what the compensation is (the CSL website says it’s usually ~$50 for normal plasma) but they’re calling a roundtrip Uber from my apartment near Ridgewood, Queens all the way to NJ, which is $108 one-way. The concierge said to reach out if there are any concerns with the first trip next week because they’re hoping for up to 2x weekly donations.
What I don’t understand is, why doesn’t the city’s antibody testing program directly link up to plasma donation? I had to go through a bunch of hassle to find out where to donate, and I think the information & coordination friction is a bigger deterrent than anything else. And why isn’t there more collection capacity in the city itself; the long commute seems unnecessary. If this is scientifically important enough to merit real donor spending from biotech, it seems like the city should make even a minimal investment in reducing process friction.
Maybe an integrated, frictionless testing & plasma donation infrastructure should be a permanent strategy for future “zero-day viruses” where convalescent antibodies are the only thing we have to treat first responders…

In the European Union Greece is moving the quickest, but still this does not sound so appealing:
Phase 1 – Until 15 June
International flights are allowed only into Athens airport.
All visitors are tested upon arrival and are required to stay overnight at a designated hotel. If the test is negative, then the passenger self-quarantines for 7 days. If the test is positive, the passenger is quarantined under supervision for 14 days.
Phase 2 – Bridge phase- 15 June to 30 June
International flights are allowed into Athens and Thessaloniki airports.
If your travel originated from an airport not in the EASA affected area list (https://www.easa.europa.eu/SD-2020-01/Airports#group-easa-downloads), then you are only subject to random tests upon arrival.
If you originate from an airport on the EASA affected area list, then you will be tested upon arrival. An overnight stay at a designated hotel is required. If the test is negative then the passenger self-quarantines for 7 days. If the test is positive, the passenger is quarantined under supervision for 14 days.
Half of new coronavirus infections in Washington [state] are now occurring in people under the age of 40, a marked shift from earlier in the epidemic when more than two-thirds of those testing positive were in older age groups.
A new analysis finds that by early May, 39% of confirmed cases statewide were among people age 20 to 39, while those 19 and younger accounted for 11%.
1. As people adjust, and the higher-risk individuals take greater precautions, and the lower risk people relax their vigilance, this is likely to happen.
2. The case for age segregation, as a remedy and protection, becomes stronger. If your policy prescriptions never change over the course of a pandemic, you are not paying sufficient attention, or you are a dogmatist, or both.
3. Universities have to worry a bit less about their students and a bit more about their faculty, at the margin.
4. As more young people acquire immunity, the incentive for yet additional young people to invest in immunity, through stochastic deliberate exposure, rises. That in turn strengthens #2 and #3.
5. Will markets play a further role in this trend? The excellent Kevin Lewis sends me the following (WSJ):
…while surging demand has proven a boon for the traders known as blood brokers who source this commodity, diagnostic companies say high prices for the blood of recovered Covid-19 patients are posing a hurdle to developing tests. ‘We’ve had a terrible time trying to obtain positive specimens at a decent rate,’ said Stefanie Lenart-Dallezotte, manager of business operations for San Diego-based Epitope Diagnostics Inc., which sells an antibody test for Covid-19…She said one broker quoted $1,000 for a one-milliliter sample of convalescent plasma, a term for the antibody-containing part of the blood from recovered patients. Executives at other diagnostics companies say they have been quoted prices of several thousand dollars for one milliliter of plasma.
What is the market-clearing price here, and what is the elasticity of exposure with respect to that price? Evolving…
Here are some answers, I put his questions — from Request for Requests – in bold:
Melancholy among academics.
We’re a pretty sorry bunch, and many of us don’t have so much professionally to live for, at least not at the relevant margin — it is easy to lose forward momentum and never recover it, given the constraints and incentives in the profession and broader pressures toward conformity. Rates of depression in academia, and especially in graduate school, are fairly high. Many of the core processes are demoralizing rather than inspiring. It is remarkable to me how much other people simply have accepted that is how things ought to be and perhaps they believe matters cannot be that different. I view the high rates of depression in academic life as a “canary in the coal mine” that doesn’t get enough attention as an indicator of bigger, more systemic problems in the entire enterprise. What are you doing with your lifetime sinecure?
Your favorite things Soviet.
Shostakovich. And the Romantic pianists, most of all Richter and Gilels. Constructivist art and ballet up through the late 1920s. The early chess games of Tal. Magnitogorsk. War memorials, most of all in Leningrad. Tarkovsky. I admire the “great” Soviet novels, but I don’t love them, except for Solzhenitsyn, whom I would rather read then Dostoyevsky. Probably the poetry is amazing, but my Russian is too limited to appreciate it.
The optimal number of math PhDs worldwide.
I would think fairly few. I am happy having lots of mathematicians, with independent tests of quality. But is the Ph.D such a great test or marker of quality? Did Euclid have one? Euler? Does it show you will be a great teacher? Maybe we should work toward abolishing the math PhD concept, but out of respect for the profession, not out of hostility toward math.
What historical works of art were anticipated to be great prior to creation, were immediately declared to be great at creation and have continued to be judged great ever since?
Overall it is striking how popular how many of the great revolutionaries have been. Michelangelo was a major figure of renown. Mozart was quite popular, though not fully appreciated. Beethoven was a legend in his time, and every Wagner opera was an event. Goethe ruled his time as a titan. A significant percentage of the very best writers were well known and loved during their careers, though of course there was uncertainty how well they would stand up to the test of time.
The future of Northern New Jersey.
Much like the present, plus defaults on the pension obligations and over time the Indian food may get worse, due to acculturation. The Sopranos will fade into distant memory, I am sorry to say, as will Bruce Springsteen. So many young people already don’t know them or care. I feel lucky to have grown up during the region’s cultural peak.
Who are the greats that still walk among us (other than McCartney)?
The major tech founders and CEOs, Stephan Wolfram, Jasper Johns and Frank Stella and Richard Serra and Gerhardt Richter and Robert Gober, a number of other classic rock stars (Dylan, Brian Wilson, Jagger, Eno, etc.), Philip Glass, Richard D. James, and note most of the greatest classical musicians who have ever lived are alive and playing today (Uchida anyone?), at least once Covid goes away. Many of the major architects. Ferrante and Knausgaard and Alice Munro. Many of the figures who built up East Asia and Singapore. Perelman. Jerry Seinfeld and Larry David. Magnus Carlsen and all sorts of figures in sports. A bunch of other people whom Eric Weinstein would list.
a Federalist plan to move from lockdown to liberty. You won’t be surprised to learn that it involves testing, testing, testing. I know, you have testing fatigue. So do I. It’s important, however, to not give up on testing too early. We are really only 6-8 weeks into the US crisis and while everyone is frustrated at the slow pace I think we will start to see leaps in capacity soon as major labs come online.and I have a piece in the Washington Post talking about
The piece makes two points. First moving too quickly can kill grandma and the economy:
The dangers of reopening without disease control — or a coronavirus vaccine or therapeutic breakthrough — are illustrated by events at the Smithfield Foods meatpacking plant in Sioux Falls, S.D. Smithfield offered workers a bonus if they showed up every day in April. Normally, bonus pay would increase attendance. But in a pandemic, encouraging the sick to haul themselves into work can be disastrous. The plan backfired. Hundreds of Smithfield employees were infected, forcing the plant to shut down for more than three weeks. If we stay the current course, we risk repeating the same mistake across the whole economy.
Second, we need a Federalist approach to testing.
The only way to restore the economy is to earn the confidence of both vulnerable industries and vulnerable people through testing, contact tracing and isolation.
There is already a bipartisan plan to achieve this; we helped write it. The plan relies on frequent testing followed by tracing the contacts of people who test positive (and their contacts) until no new positive cases are found. It also encourages voluntary isolation, at home or in hotel rooms, to prevent further disease spread. Isolated patients would receive a federal stipend, like jurors, to discourage them from returning to workplaces too soon.
But our plan also recognizes that rural towns in Montana should not necessarily have to shut down the way New York City has. To pull off this balancing act, the country should be divided into red, yellow and green zones. The goal is to be a green zone, where fewer than one resident per 36,000 is infected. Here, large gatherings are allowed, and masks aren’t required for those who don’t interact with the elderly or other vulnerable populations. Green zones require a minimum of one test per day for every 10,000 people and a five-person contact tracing team for every 100,000 people. (These are the levels currently maintained in South Korea, which has suppressed covid-19.)
Most Americans — about 298 million — live in yellow zones, where disease prevalence is between .002 percent and 1 percent. But even in yellow zones, the economy could safely reopen with aggressive testing and tracing, coupled with safety measures including mandatory masks. In South Korea, during the peak of its outbreak, it took 25 tests to detect one positive case, and the case fatality rate was 1 percent. Following this model, yellow zones would require 2,500 tests for every daily death.
…A disease prevalence greater than 1 percent defines red zones. Today, 30 million Americans live in such hot spots — which include Detroit, New Jersey, New Orleans and New York City. In addition to the yellow-zone interventions, these places require stay-at-home orders.
One virtue of this plan is that conforms with the common sense of people where they live. People in New York have seen their friends die and understand that stricter rules make sense. People in Montana haven’t seen the crisis up close and so their common sense and our testing strategy require less stringent rules.
We do need testing even in low-prevalence areas, however, and we need to be able to mobilize a lot of testing and tracing quickly to cap flare ups.
One danger of the current situation is that many of the places which have not yet been hit hard by COVID-19 are also the places with the most natural danger as they have lots of elderly with comorbidities.

My long-running skepticism about the safety and efficacy of the FDA is fast becoming conventional wisdom. Even normal people can’t believe what they are doing. This piece on the FDA in the New York Times reads like something I might have written for CATO.
An innovative coronavirus testing program in the Seattle area — promoted by the billionaire Bill Gates and local public health officials as a way of conducting wider surveillance on the invisible spread of the virus — has been ordered by the federal government to stop its work pending additional reviews.
…the program, a partnership between research groups and the Seattle and King County public health department that had been operating under authorization from the state, was notified this week that it now needs approval directly from the federal government. Officials with the Food and Drug Administration told the partnership to cease its testing and reporting until the agency grants further approval.
…the Seattle program …has wide backing, including from public health leaders, the Fred Hutchinson Cancer Research Center and Mr. Gates, whose foundation has been deeply involved in fighting the pandemic. The Centers for Disease Control and Prevention also provided an in-person technical adviser to the project.
Dr. Eric Topol, the director of the Scripps Research Translational Institute, who is not involved in the Seattle group, said it had “emerged as leading lights in this whole Covid-19 crisis.” He said it was “bizarre” that the F.D.A. would halt such a project.
By the way, Dr. Helen Chu, one of the leaders of the Seattle project, was one of the first Emergent Ventures prize winners for her work fighting the coronavirus (excellent pick, Tyler!). As you may recall, Chu started testing for coronavirus in an already running flu study without permission. Until she was shut down.
To repurpose the tests for monitoring the coronavirus, they would need the support of state and federal officials. But nearly everywhere Dr. Chu turned, officials repeatedly rejected the idea, interviews and emails show, even as weeks crawled by and outbreaks emerged in countries outside of China, where the infection began.
By Feb. 25, Dr. Chu and her colleagues could not bear to wait any longer. They began performing coronavirus tests, without government approval.
Federal and state officials said the flu study could not be repurposed because it did not have explicit permission from research subjects; the labs were also not certified for clinical work. While acknowledging the ethical questions, Dr. Chu and others argued there should be more flexibility in an emergency during which so many lives could be lost. On Monday night, state regulators told them to stop testing altogether.
The failure to tap into the flu study, detailed here for the first time, was just one in a series of missed chances by the federal government to ensure more widespread testing during the early days of the outbreak, when containment would have been easier. Instead, local officials across the country were left to work in the dark as the crisis grew undetected and exponentially.
History repeats itself, first as tragedy then as farce.
Addendum: I see now that Tyler covered this a bit earlier in the post below. I’ll leave this post up, however, as I have more details including Tyler’s connection.
5. What it is like to land in Hong Kong and try to enter (recommended, short photo essay).
10. I find this kind of defense convincing for many research efforts, but not for actual real world problems with immediate decisions to be made: “I don’t know the 2 Swedish models in question but in general it is disingenuous to say the models that do not try to take into account changes in human behavior failed because people behaved in ways the models didn’t model. The models were upfront about the scenarios addressed.”
That is the topic of my latest Bloomberg column, here is one excerpt:
There has been surprisingly little debate in America about one strategy often cited as crucial for preventing and controlling the spread of Covid-19: coercive isolation and quarantine, even for mild cases. China, Singapore and South Korea separate people from their families if they test positive, typically sending them to dorms, makeshift hospitals or hotels. Vietnam and Hong Kong have gone further, sometimes isolating the close contacts of patients.
I am here to tell you that those practices are wrong, at least for the U.S. They are a form of detainment without due process, contrary to the spirit of the Constitution and, more important, to American notions of individual rights. Yes, those who test positive should have greater options for self-isolation than they currently do. But if a family wishes to stick together and care for each other, it is not the province of the government to tell them otherwise.
What I observe is people citing those other countries as successes, wishing to “score points,” but without either affirming or denying their willingness to engage in coercive quarantine. Here is another bit:
Furthermore, all tests have false positives, not just medically but administratively (who else has experienced the government making mistakes on your tax returns?). Fortunately, current Covid-19 tests do not have a high rate of false positives. But even a 1% net false positive rate would mean — in a world where all Americans get tested — that more than 1 million innocent, non-sick Americans are forcibly detained and exposed to further Covid-19 risk.
Coercive containment was tried during one recent pandemic — in Castro’s Cuba, from 1986 to 1994, for those with HIV-AIDS. It is not generally a policy that is endorsed in polite society, and not because everyone is such an expert in Cuban public health data and epidemiological calculations. People oppose the policy because it was morally wrong.
And what about uncertainty? Is it really a safe bet that America’s quarantine policy would be executed successfully and save many lives? What if scientists are on the verge of discovering a cure or treatment that will lower the Covid-19 death rate significantly? Individual rights also protect society from the possibly disastrous consequences of its own ignorance.
Here are a few points that did not fit into the column:
1. I am not opposed to all small number, limited duration quarantine procedures, such as say holding Typhoid Mary out of socializing. This same point also means that a society that starts coercive quarantine very early might be able to stamp out the virus by coercing relatively small numbers of people. (It is not yet clear that the supposed successes have achieved this, by the way.) That is very different from the “mass dragnet” to be directed against American society under current proposals.
2. I am familiar with the broad outlines of American quarantine law and past practice. I don’t see that history as necessarily authorizing how a current proposal would have to operate, and on such a scale. In any case, I am saying that such coercive quarantines would be wrong, not that they would be illegal. I believe it is a genuinely open question how current courts would rule on these matters.
3. From my perch from a distance, it seems to me that Human Challenge Trials for vaccines are more controversial than is mass forced quarantine. I could be wrong, and I would gladly pursue any leads on the current debate you might have for me. Who are the philosophers or biomedical ethicists or legal scholars who have spoken out against such policies?
A number of commentators suggest that the real problem is President Trump, rich people overly concerned with tax cuts, a Republican Party with a deregulatory ideology, and so on.
Instead I have been repeating insistently that “our regulatory state is failing us.” The FDA and CDC, for instance, have through their regulations made it harder for testing and also widespread mask supply to get off the ground.
I don’t see how you can blame (supposed) deregulatory fervor for the presence of too many regulations, as we have been observing in these instances.
I do think you can blame President Trump, along multiple dimensions, for a poor response to the pandemic, see my grades here. (If there were a separate risk communication grade, Trump would get an F minus for that.) Nonetheless a regulatory state cannot be said to work well if it requires such extraordinary attention from a sitting president.
It can be the case that both Trump and the permanent bureaucracy are at fault. If something takes a long time to get done for reasons relating to preexisting rules, regulations, and laws, usually the current president is not directly at fault for that particular problem. Was it only Trump’s fault, for instance, that the permits to build a mask factory can take months to acquire? Or that the HHS did not respond to inquiries about gearing up mask production in Texas? Or that a law had to be changed to allow industrial companies to sell quality masks to hospitals? Or that so many a-legal or extra-legal activities (e.g., rich people arranging deliveries by plane, etc.) had to occur to sneak masks into this country? That the trade barriers on masks persisted for so long? (And yes likely the Trump administration is at fault for de facto toughening restrictions on masks from China.)
It is fine to say “the buck stops here,” and to criticize Trump for not having erected processes to be more aware of these problems and to dissolve them more quickly. I would agree with some of those criticisms, while noting the Trump administration also has tried to ease many of the regulations hampering adjustment.
This is more something on the horizon, but how do these apples make you feel? Comforted? The fault of plutocratic Republicans most of all?
And in both cases, vials and stoppers, a vaccine manufacturer cannot just switch to a slightly different product or another brand. They typically have to run manufacturing changes by FDA first, which could make quick supplier changes to curb shortages a difficult prospect.
The FDA can decide how flexible it will be about this type of change, says Sklamberg. The agency said in a December 2017 draft guidance that companies could note some changes in their annual reports rather than waiting for approval, but it has not finalized the policy.
The ability to switch products could be crucial as the entire world readies for a possible vaccine and vies to secure their supplies.
If you wish, consider a simple question. When the CDC pooh-poohed masks early on, or botched their testing kit thereby delaying U.S. testing by weeks or maybe months, did the permanent staff of the CDC rise up and rebel and leak howling protests to the media, realizing that thousands of lives were at stake? That is surely what would happen if say the current FDA announced it was going to approve thalidomide.
Those are still cases of our regulatory state failing us.
Germany is being closely watched worldwide as the most successful large European country in curbing the spread of the virus, partly thanks to massive testing, which has prompted a partial reopening of the economy. Merkel has frequently said the reproduction rate of the new coronavirus must be held below 1 to prevent the health system from being overwhelmed.
But the Robert Koch Institute for public health said the rate hovered above this critical threshold for the third consecutive day with an estimated value of 1.07 on Monday, after 1.13 on Sunday.
That Germany does not have its R below one is, in a nutshell, why short-run measurements of coronavirus responses are not very reliable. And why “we need to lock down until full testing is up and running” is not necessarily convincing. Here is the full story.
The evidence indicates that GRE scores predict graduate school success, general intelligence, and also that SAT scores predict later success in science. Here is further evidence, and here is yet further evidence.
You don’t have to think that “high GRE score fields” are better than “low GRE score fields.” Many of my friends, for instance, think string theory is intellectually bankrupt, despite many of its proponents being very, very smart. I don’t have an opinion on string theory per se, but my friends might be right, and in any case I would rather read books from cultural studies, a lower GRE score field.
If you wish to understand the relative strengths and pathologies of theoretical physics and cultural studies, you cannot do that without knowing that the former is a relatively high GRE score field (or the equivalent) and that the latter is a relatively low GRE score field (or the equivalent).
There are many top economists on Twitter, most of them Democrats, who would never ever utter a word about GRE scores in a blog post or on Twitter. Yet when on an admissions committee, they will ruthlessly enforce the strictest standards for math GRE scores without hesitation. Not only in top ten programs, but in top thirty programs and even further down the line in many cases. It is very, very hard to get into a top or even second-tier economics program without an absolutely stellar math GRE score, and yes that is enforced by the same humans who won’t talk about the issue.
Just in case you didn’t know that.
Personally, I feel it has gone too far in that direction, and economics has overinvested in one very particular kind of intelligence (I would myself put greater stress on the old GRE subject test scores for economics, thus selecting for those with an initial interest in the economy rather than in mathematics).
When I did graduate admissions for George Mason University, I very consciously moved away from an emphasis on GRE scores, and for the better. My first goal was simply to take in more students, and a more diverse group of students, and in fact many of the later top performers were originally “marginal” students by GRE standards. Looking back, many of our top GRE-scoring students have not done better than the peers, though they have done fine. For GMU these admission criteria are (in my view) more like the Rosen-Roback model than anything else, though I would readily grant Harvard and MIT are not in the same position.
If you are afraid to talk about GRE scores, you are afraid to talk about reality.
That is the topic of my latest Bloomberg column, here is one bit:
The first wave of the Covid-19 pandemic brought serious economic damage for thinly capitalized face-to-face retailers, such as small family-owned restaurants. But many of those same institutions will lead the recovery — that is, if they have built up trust among their patrons. If they ask me to sit outside to eat my meal, I will trust that their kitchen procedures are “clean enough,” because I believe that the boss is watching [there I am referring to two of my favorite local places].
It is also worth asking whom I do not trust. When it comes to providing a fully clean and safe store, I do not trust most of the big-box retailers. I trust them just fine in ordinary times, but no single manager can oversee the entire cleaning and disinfectant operation. And can they monitor Covid-19 in the air? If they tell me that “all possible precautions have been taken,” I might believe their words, but I won’t believe that is enough.
The NBA is wondering if it can resurrect its playoffs at a dedicated location with television coverage but no audience in the stands. So far the teams are hesitant, in part because they are afraid of public resentment if the league’s millionaire players have access to Covid-19 tests while the general public does not.
The reality is that if the NBA announced it was buying up a lot of tests, it would boost the supply of tests. That could provide testing with valuable positive publicity, with the NBA serving as a role model for what other businesses might do. Yet the NBA does not yet trust its fans to see things in such a positive light, and so reopening is delayed. There might be some danger to playoffs games without fans, but surely less than in, say, collegiate or professional football, where injuries and concussions are built into the very nature of the competition.
Which are the businesses that you really trust in matters pandemic?
