Who is getting the “stimulus”?
Do your think that your $1000 check is a big deal? Consider this:
Assuming that there are 130 million households, and each household gets $1000, that would amount to $130 billion. Yet the “stimulus” is $2 trillion, so that leaves a lot unaccounted for. Let’s assume that the bill contains $.02 trillion in funds for medical supplies along with $0.13 trillion in checks for households. That leaves $1.85 trillion for special interests.
I know that it’s too late to do anything about it. I should just shut up and move on. But I’m in a bitter mood today. Sorry.
UPDATE. It looks closer to $3000 per household. In that case, call it $0.4 trillion for households and $1.58 trillion for special interests.
Thinking fast and slow
What many people do not realize is that “the speed premium” is vastly higher when a deadly virus is doubling in reach every five to seven days.
We needed a billion masks weeks ago.
But thinking is slow. Eons ago, on March 13, I wrote,
My working assumption is that American business and political elites are two weeks behind in their attempts to address the virus crisis. The steps they are taking now were necessary two weeks ago. And the steps that are needed now will not be taken for another two weeks.
Here are some predictions going forward:
1. The FDA and CDC were slow and often counterproductive in this crisis. But going forward, praise will be heaped on these experts.
2. If and when public health experts finally adopt something like the masks and scarves strategy, they will fill the journals will research papers showing that lockdowns were the key to beating this crisis.
3. No matter how special-interest-fueled, unhelpful, or even counterproductive the $2 trillion “stimulus” turns out to be, economists will fill the journals with research papers showing how it saved the economy.
My point is that it does not pay to be right about the crisis. That is playing Game 1. What pays is to be on the side of the powerful elites. That is playing Game 2. And nothing makes me feel more bitter and betrayed than seeing all the Game 2ers out there, patting each other on the back and gaining in status.
Whose status should be going up? Probably Razib Khan, who on Twitter now styles himself “Self-quarantine if you Khan.”
On March 18, Razib Khan wrote,
To be frank, most of the skeptics of the impact of coronavirus are not very smart.
How about me? On March 12, I wrote,
Even though we have no symptoms and no reason to believe we have been infected, my wife and I are going to try to do everything reasonable to reduce outside contact for a while. Call it “social distancing” or self-quarantining.
How about the former Mencius Moldbug?
On February 1–February first!–Curtis Yarvin wrote,
there is no good reason for anyone to be flying across the Pacific. The same may soon be true of the Atlantic. And certainly, no one should be flying in or out of mainland China—except via a quarantine facility. . . And Western public health authorities, though their epidemiology remains first-rate, cannot say this, or even think it, because of their internationalist intellectual doctrine, just one aspect of the great American progressive tradition of government.
If I can guarantee one thing, it is that his status will not go up. I am not saying we should drop all our existing beliefs and adopt his, but we ought to take into consideration that his view of the world made him quicker to spot the threat.
Scott Sumner, Amy Willis, and me
On the macroeconomic policy response to the virus crisis. I start with the argument for having everyone cover their faces. Maybe if we did that to slow the spreading of the virus instead of hiding in our homes, we wouldn’t have such big economic problems.
Note that I compare the situation to the second World War, as does Tyler Cowen.
Compare side by side
Two approaches to dealing with the combined public health crisis and economic crisis.
(1) Have people privately reduce mingling with one another PLUS have government order people to take steps to reduce mingling. Then try to deal with the economic consequences by increasing government spending by $2 trillion or more, with a share of that to be financed by money creation assuming the government is not going to be able to borrow that much on such short notice.
(2) Instruct people on how to tie a scarf over the nose and mouth.* Meanwhile, ramp up mask production, so that as soon as possible masks are widely available. Point out to everyone that wearing something over their nose and mouth is a public duty. It’s not (just) protecting yourself from infection, it protects other people from being infected unknowingly by you. If necessary, legislate fines and enforce them when people go out in public without wearing something over nose and mouth.
With either (1) or (2), you still need to isolate people who are coughing and who are known to have the virus. With either (1) or (2), you need to be supportive of health care workers, search for cures, search for a vaccine, and so on.
With either (1) or (2), there is an imposition on liberty. With (1), you tell people where they are allowed to go and tell businesses they have to shut down. With (2), you tell people that they can’t leave their noses and mouths naked.
With either (1) or (2), there will continue to be new cases of the virus. The goal is to reduce the spread of the virus down to a level that will keep hospital emergency rooms from getting overwhelmed. Both (1) and (2) leave gaps. For example, under (1) there will be some mingling, either by people breaking the rules or people who are exceptions to the rules. But even though there are gaps, it seems plausible that either approach could greatly reduce the spread rate.
With (1), a lot of economic activity is curtailed. With (2), some people will still be leery of getting onto planes or going on cruises. Eating in restaurants will be awkward, and many people will put off doing so. But more businesses will feel ok about opening their offices. And more individuals will feel ok about getting haircuts, shopping in stores, and going to sporting events–provided that they see everyone around them wearing masks (which should turn out to be the case, if social pressure and law enforcement are effective).
With (1), government finance will be shaky. I don’t know why more people aren’t worried about this. If there is no down side to increasing spending by 10 percent of GDP, why doesn’t the government do so all the time? I think that the answer is that eventually you turn into Zimbabwe, with hyperinflation. Hyperinflation is like a virus, in that by the time you can see it, it’s too late to stop it. Hyperinflation destroys the social fabric. It’s something to fear.
Finally, I wonder how charitable I should be about the health advisers, economic pundits, and political leaders who are committed to (1). Those poobahs will be more important if we implement (1) instead of (2). I hope that is not what tips the decision.
Thanks to Russ Roberts for a helpful conversation.
UPDATE: *We would also need to instruct people on sanitary use of a scarf. Best not to reverse it, not to touch it while wearing it, and also to wash it or heat treat it frequently. I would like to thank Dallas Weaver for pointing this out. He has some advice on the use of masks. In an email, he writes “I assume you have noticed that all the countries that are under control use masks.”
Scarves now, masks later
Some arguments against the masks and gloves approach:
1. Not enough masks. But meanwhile, you can tie a scarf around your mouth and nose. No, it doesn’t filter out everything. But it could filter out enough. Then go home and wash the scarf. The point is to reduce my ability to spread the virus to you, in case I have it without knowing it. At lower cost than shutting down lots of businesses.
2. You can still get the virus from doorknobs. Maybe this is true–we still have not done the experiment. If it is true, then we can try to mitigate it using handwashing, being careful how we touch things, and using disinfectant. No, that won’t be perfect, but again the goal is reduction of spread, not total elimination.
3. People might become overconfident, thinking that scarves confer immunity. Probably true for *some* people, but I would hope that if the approach is clearly communicated, most people would continue taking other precautions. But they would feel less nervous about going to stores or getting their hair cut.
Look, people, our current approach looks like stupidity layered on stupidity. Because we don’t have a clear picture of prevalence or how it spreads, we are advising people to stay away from one another. Because staying away from one another cripples business, the stock market has plunged, the Fed is taking over more of the financial market, and Congress is wrangling over a $1.5 trillion “stimulus,” i.e., trough for special interests to feed at. And we are witnessing President Trump get into a battle royale with his health advisers. Is this what you want?
Given all of the issues involved, the optimum spread rate for the virus from a policy perspective isn’t going to be zero. If we can just come up with an alternative that allows people to mingle in public while keeping the spread rate low enough to avoid another Italy or NYC, that is good enough, in my opinion. I am looking for ways to keep our hospitals from becoming overwhelmed that don’t involve so much economic dislocation.
Scarves now, masks when they’re ready. I would like to thank commenter Handle for the scarves suggestion.
Bring on the Masks and Gloves!
Scott Alexander looks into the question of whether a surgical mask can help keep you from getting infected by others. Short answer: very few reliable studies, but the answer seems to be “yes.”
But he says that this is reliable:
As far as I can tell, both sides agree on some points. They agree that surgical masks help prevent sick people from infecting others.
Well, that’s it then! What’s the purpose of social distancing? To keep sick people from infecting others. But it seems like you could accomplish the same thing by having everyone where a mask. That would settle the issue of “asymptomatic spreading.” Nobody could be a spreader. In that case, masks are an alternative to killing the economy.
The government could do this:
1. Have the taxpayers pay manufacturers to produce a zillion surgical masks. Maybe gloves also.
2. Dispense the masks, paid for by taxpayers.
3. Tell people they can mingle in public, but only if they wear masks–otherwise they are subject to fines. Maybe encourage the use of gloves, also.
It seems like a policy that is at least worth trying in some locations, to see if it works.
A story in Time Magazine Asia says,
Nearly everyone on Hong Kong’s streets, trains and buses has been wearing a mask for weeks—since news emerged of mysterious viral pneumonia in Wuhan, China
. . .Yet, in the U.S., wearing a face mask when healthy has become discouraged to the point of becoming socially unacceptable. The U.S. government, in line with World Health Organization recommendations, says only those who are sick, or their caregivers, should wear masks.
Are the official experts at WHO and in the U.S. idiots? Or am I the idiot? I am curious to know.
Two ways I could imagine the conversation going
The White House is discussing easing social-distancing guidelines as early as next week amid a broader debate over how much economic loss the country can bear to save an unknowable number of lives threatened by the novel coronavirus pandemic.
President Trump has told people that he wants to reopen the economy as soon as possible but his interest runs counter to the advice of public health experts, including in the administration, who have warned that the guidelines remain necessary.
Here are two imaginary conversations, one with a traditional health adviser named Suit, and one with an analytical health adviser named Geek.
—–1—–
President: I want to lift the social-distancing guidelines by the end of next week.
Suit: You can’t do that! The virus will spread! People will die!
President: But we’re killing the economy. I’m going to do it anyway.
Suit: I resign!
—–2—–
President: I want to lift the social-distancing guidelines by the end of next week.
Geek: You can’t do that! We need to first test a random sample in each of several geographical areas to see the distribution of the virus in the population. And we also need to run the experiment, probably a few times to get robust results. And we need to agree on benchmarks for the results that would have to be met in order to lift the guidelines.
President: What’s the point?
Geek: The random sample will tell us the prevalence of asymptomatic infected people in various geographic areas. The experiment will tell us how dangerous those people are, meaning how likely it is that they will infect others while asymptomatic.
If the experiment finds that the doorknob infection rate is less than 5 percent and the in-person infection rate for asymptomatic virus carriers is less than 5 percent, then we can safely lift many of the restrictions. Continue to encourage disinfecting and handwashing, and avoid large gatherings, but open up businesses.
If the experiment finds a result of more than 20 percent for either the doorknob infection rate or the in-person infection rate, then we should not lift the social-distancing guidelines. We would need to first meet benchmarks for treatment capacity. That might require training and equipping more health care workers, or better yet finding a reliable pharmaceutical treatment.
Suppose the experiment finds a result between 5 and 20 percent for either the doorknob infection rate or the in-person infection rate. Then decide differently for each region. If the prevalence of asymptomatic infection in a region is either very low (less than 5 percent) or very high (over 30 percent), you can lift the guidelines in those regions.
If the prevalence is currently low, then lifting the guidelines will cause the virus to spread in that region, but starting from a low baseline. So in several weeks you may have to recommend restoring restrictions in that region.
If the prevalence is high, then the people with the virus will already have encountered most of the people that they might infect (social interactions are not random). The spread rate going forward is likely to be low, as long as people stay stick to normal routines and avoid interactions with strangers or unfamiliar places.

Note: The numbers in the conversation are purely illustrative. I have not thought carefully about what the actual numbers ought to be.
Nice try, economists
1. You asked for cost-benefit analysis? Here is Luigi Zingales.
we are talking about roughly $9 million per lost life, which, multiplied by the 7.2 million extra deaths, yields $65 trillion.
Thus, even the simplest cost-benefit analysis suggests that the US government should be willing to spend up to $65 trillion to avoid extra deaths. Since $65 trillion is 3 times the US GDP, the United States should be willing to stop production for up to 3 years in order to eliminate the extra deaths.
Satisfied? I’m not. Forget the wild assumptions (7.2 million extra deaths). We need to be careful about thinking on the margin.
Consider three scenarios:
a) zero social distancing
b) social distancing decisions made entirely by the private sector
c) social distancing imposed by the government
Scenario (a) is irrelevant, but people tend to forget that. But relative to (a), (b) is going to both reduce deaths and impose economic costs.
The relevant policy choice is between (b) and (c). The economic case for (c) is that when I go to work I calculate the risk to myself, but I do not include the risk I impose on the people who ride mass transit with me. But describing the externality is not enough. We need to guess how much social benefit comes from moving from (b) to (c) and compare it to the cost.
My own view is that, to a first approximation, moving from (b) to (c) imposes no economic cost, because I think that if the death rate soars under (b) the economic cost will be enormous, also. That’s just my intuition, based on what I think is the importance of social capital, which in turn I think depends on people feeling that their fellow citizens care about them. So it’s a very soft concept, not something I can put a hard number to.
What I would like to better estimate is how many deaths (c) saves relative to (b). But you know how frustrated I am with the inability to do reliable analytics on something like this. Meanwhile, I am willing to assume that the marginal life savings are high.
Under this plan, a person whose earnings fall to zero this year keeps all of the social insurance payments and does not pay the surtax. A person whose earnings fall by half keeps half of the payments and returns half. A person whose earnings remain the same (or increase) returns everything: They will have just gotten a short-term loan.
The specifics are at the link. This is clever. Maybe too clever. Any scheme like this invites gaming. For example, suppose my earnings go up, so I should not get to keep any of the money. In that case, I just sell some stock, take the capital losses, and as far as the IRS is concerned my income did not increase. It is always somewhat advantageous to me to take losses, but this would produce a proportionately larger payoff from doing that.
Still, Mankiw’s idea is far better than what I’m guessing what Congress will come up with.
Honestly, I don’t know what everyone is worried about with all this stimulus stuff. In 1945, we had just been through four years of war, and the economy bounced back way more quickly than the Keynesians thought possible (please click on the link). I’d give it a chance to bounce back on its own after a war against a virus that has fewer casualties and shorter duration.
Suits vs. geeks in the virus crisis
1. Allison Schrager writes,
Among the unknowns about the virus: the true hospitalization and death rates; how infectious it is; how many asymptomatic patients are walking around; how it affects young people; how risk factors vary among different countries with different populations, pollution levels and urban densities. It seems certain the virus will overwhelm hospitals in some places, as it has in China and Italy. We also don’t know how long these extreme economic and social disruptions will last. Without reliable information, predictions are based on incomplete data and heroic assumptions.
…The way forward is testing as many people as possible—not only people with symptoms. Some carriers are asymptomatic. California is starting to test asymptomatic young people to learn more about transmission and infection rates. Testing everyone may not be feasible, but regularly testing a random sample of the population would be informative.
This is the analytical mindset, which is sorely needed. What I called the “suits vs. geeks divide” in 2008 is haunting us again. Ten days ago, the challenge was to get the suits to understand exponential growth. Hence, they were two weeks behind. Now, the challenge is to get the suits to make decisions based on rational calculations as opposed to fears or whoever shouts the loudest in their ears.
But much needs to change. Think about the “analytics revolution” in baseball. In the 1980s, the revolution started*, with Bill James and others questioning the value of the routinely-calculated statistics. Just as one example, data geeks discovered that a batter’s value was better measured by on-base percentage than batting average, even though the latter was prominently featured in the newspapers and the former was not. Soon, the geeks started longing for statistics that weren’t even being kept, and they started efforts to track and record the desired metrics.
(*In 1964, Earnshaw Cook wrote an analytical book, but he drew no followers, probably because personal computers had not yet been invented.)
Based on what we are seeing now, I think that epidemiology is ripe for an analytics revolution. To me as an outsider, the field relies too much on simulations using hypothetical parameters and not enough on identifying the data that would be useful in real time and making sure that the such data gets collected.
A key coronavirus unknown is the asymptomatic rate, the fraction of those infected who have either no symptoms or symptoms mild enough to be confused with a common cold and not reported. A high asymptomatic rate is decidedly good news: it would mean that the death rate is lower, that the hospital system is less likely to be overrun, and that we are closer to achieving herd immunity. From an economic point of view, a high asymptomatic rate means it is safe to relax restrictions relatively soon, and that hospitalizations can be kept within limits as economic activity resumes.
Conversely, a low asymptomatic rate would require trading off losing many lives against punishing
economic losses.Neither the asymptomatic rate nor the prevalence of the coronavirus can be estimated if tests are prioritized to the symptomatic or if the included asymptomatic are unrepresentative (think NBA players).
Instead, we need widespread randomized testing of the population.
It may seem counterintuitive that we should be rooting for a high number of people running around with the virus without symptoms. But that would mean, among other things, that their presence is not creating huge risks for the rest of the population. You want the ratio of mild cases to emergency-room cases to be high.
We should be doing a stochastic process random probability sample of the country to find out where the hell the virus really is.
Note that he has a lot of anger against President Trump. I won’t push back at Mr. Brilliant (I’m not being sarcastic, that is his name), but I think his rhetoric is stronger than his case. See my post on anger.
4. Dan Yamin says,
But there is one country we can learn from: South Korea. South Korea has been coping with corona for a long time, more than most Western countries, and they lead in the number of tests per capita. Therefore, the official mortality rate there is 0.9 percent. But even in South Korea, not all the infected were tested – most have very mild symptoms.
The actual number of people who are sick with the virus in South Korea is at least double what’s being reported, so the chance of dying is at least twice as low, standing at about 0.45 percent – very far from the World Health Organization’s [global mortality] figure of 3.4 percent.
He is at least taking care not to take statistics at face value. But don’t be satisfied with trying to guess based on data that don’t measure what you want. Try to get the authorities to provide you with the numbers you need.
