On the Spreading of Monkeypox

New York City has become the second major U.S. city after San  Francisco to declare a state of emergency due to the rise of monkeypox cases: “New York City is currently the epicenter of the outbreak, and we estimate that approximately 150,000 New Yorkers may currently be at risk for monkeypox exposure.”

With the country and the world still feeling the economic/social/personal effects of one pandemic, is there another one on the way? I don’t know, having no special training in epidemiology, but have tried to peruse some reliable sources to find out what I could, and share this information for your examination. I will paste in a general page from a UC Davis article, then conclude with a CDC snip on transmission details.

It seems that monkeypox typically takes pretty close physical contact (especially with skin, body fluids, or e.g. towels/clothing)  to spread, with having multiple romantic partners being a high risk factor. This is the opposite of COVID transmission, where just being in the same room puts you at high risk. However, as with COVID, someone can be contagious in the early stages before they show obvious symptoms. Based on all this, my guess is that monkeypox will not spread in the general population very much, but it will spread significantly in some groups and locales. But that is just my guess.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

From UC Davis “Monkeypox: What you need to know about this rare virus:

What are the signs and symptoms of monkeypox? At what point is it infectious?

Monkeypox starts with fever, then general body aches, malaise, and muscle aches. with the first symptoms are similar to influenza. Those usually precede the development of a rash. You have probably seen photos of the rash. It’s really hard to miss. It starts as macules, which are flat lesions. Then it forms a firm nodule. From there, it becomes a blister, then a pustule (a blister containing pus) and then it scabs over.

According to the Centers for Disease Control and Prevention (CDC), the incubation period (The time from infection to symptoms) for monkeypox is usually 7 to 14 days, but it can range from 5 to 21 days.

People may be contagious at the early signs of fever and stay infectious through the rash until the skin scabs and heals over.

How is it transmitted?

Monkeypox is transmitted through close person-to-person contact with lesions, body fluids and respiratory droplets, and through contaminated materials such as clothing or bedding.  [[ see more on transmission below]]

Can you die from monkeypox? 

Most people with monkeypox will recover on their own. But 5% of people with monkeypox die. It appears that the current strain causes less severe disease. The mortality rate is about 1% with the current strain….

What are the treatments for monkeypox? Is there a vaccine for monkeypox?

The smallpox vaccine has some cross protection against monkeypox. The vaccine is being made available through public health for people who have had contact with confirmed or suspected cases of monkeypox. If the vaccine is given within four days of exposure, it protects about 85% of the time. Even if the vaccine is given up to two weeks after exposure, it may modify the disease, making it less severe. 

In addition, there are some antivirals and immunoglobulins that are available to treat monkeypox.

Is there a way to test for monkeypox?

If a health care provider suspects that a patient has been exposed to monkeypox, they can get a sample of a lesion and send it to the state for testing. If it turns out positive, the result will be confirmed at the CDC.

~~~~~~~~~~~~~~~~~~~~~~~~~

From CDC “How It Spreads”:

Monkeypox spreads in a few ways.

  • Monkeypox can spread to anyone through close, personal, often skin-to-skin contact, including:
    • Direct contact with monkeypox rash, scabs, or body fluids from a person with monkeypox.
    • Touching objects, fabrics (clothing, bedding, or towels), and surfaces that have been used by someone with monkeypox.
    • Contact with respiratory secretions.
  • This direct contact can happen during intimate contact, including:
    • Oral, anal, and vaginal sex or touching the genitals  or anus of a person with monkeypox.
    • Hugging, massage, and kissing.
    • Prolonged face-to-face contact.
    • Touching fabrics and objects during sex that were used by a person with monkeypox and that have not been disinfected, such as bedding, towels, fetish gear, and sex toys.
  • A pregnant person can spread the virus to their fetus through the placenta.

A person with monkeypox can spread it to others from the time symptoms start until the rash has fully healed and a fresh layer of skin has formed. The illness typically lasts 2-4 weeks.

Converting office space and why second-best solutions are what move the world forward

Subscribing to the “Housing Theory of Everything” is to confront the fact that a problem can 1) be important, 2) effect (nearly) everyone, 3) have an obvious and welfare improving policy solution, and 4) still be politically stuck. Whether it’s classic prisoner’s dilemmas or a more subtle transitional gains traps, the reality is that building housing has proven incredibly difficult because there is a group whose wealth is overly concentrated in the stock of housing they own (i.e. nearly every homeowner in the US) and who have every incentive to fight to prevent new housing from being built because restricting housing supply increase the value of their propterty.

That’s it. That’s the whole story, everything else is bookkeeping and tactical anecdotes. So how do we solve this problem? One way is to motivate large swaths of voters to push for reform, but there’s only the entire body of political theory and history telling you that’s easier said than done when the opposition is concentrated and organized.

The thing is, building more housing is the “first best” solution- it’s not the only solution. Should we increase the housing stock, lower prices, make the average person wealthier and more economically secure, reduce homelessness, and spend all of eternity celebrating the victory of common sense in the halls of Valhalla? Yes, of course. But that “first best” solution isn’t available in a lot of places (see the previous two paragraphs). Besides beating our heads against the wall in the hopes of victory one spoonful of brick at a time, what else can we do? We can go looking for second-best solutions, particularly ones where the political opposition is softer and less organized.

Converting office space to residential housing is a near Platonic-ideal second best solution. Why? Because it produces more housing, albeit with the costs of conversion and likely subperfect design. What makes it a dream second-best solution for our dilemma, however, is all of the opposition mechanisms it dodges:

  1. There’s nothing remotely historic about most of these buildings.
  2. The are structured in such a way that lend themselve to high-density housing (i.e. apartment and condo towers).
  3. They’re predominantly in relatively dense urban and edge-city areas.
  4. Whatever views or skylines they are obstructing are already obstructed!
  5. There’s a built in interest group to push for the conversion (i.e. the building owners).
  6. There’s no pre-existing tenant or tenants who’s losses can be highlighted at the expense of everyone else’s gain.

First and second best categorization are always a little squishy because they depend on what you include in the costs and benefits. Building new housing from scratch might seem obviously the best possible outcome, but once you factor in the political costs of zoning and approval, there’s going to be a lot of locales where building conversion is the far lower cost option. I’m very much team “work from home” and this is just one more reason you should join our merry band of robe and slipper-types. Hollow out the offices, convert the buildings to housing, and watch the urban landscape transform from gray and glass offices to a utopia of urban singles skipping from brunch to brunch until their kids are born and their metabolisms slows down.

Now, to be clear, there is no political free lunch here. There will still be costly and difficult re-zoning obstacles in lots of places. Plenty of these building will need to be brought up to code. The locations may not be ideal relative to schools. But those costs and concerns are trifles when considered in the context that the median income in half of US cities is insufficient to rent a two bedroom apartment for less than 30% of gross income.

Democracy is messy and there’s no changing that. While it makes for bad sloganeering and will never insulate you from getting slagged on twitter, the reality is that second best solutions are what move peaceful societies forward. We have a lot of coalitions to keep happy, they all want something for themselves, and nothing is free. We have to work with what we got.

And what we got is a bunch of office buildings that nobody wants to work in anymore. Let’s live in them!

…and then work from home in them? In what used to be the offices we didn’t want to work in?

Yes.

See New York City for free

When writing in the capacity of an economist, one should never pitch an experience as “free”. Going anywhere has opportunity costs, especially if you have to pay several tolls on the New Jersey Turnpike. That said, if you want kids to see New York City as part of a road trip, consider Liberty State Park.

You can enter and park for free. There is a playground, picnic tables, and lots of trails. You can see the Statue of Liberty, Ellis Island and Manhattan across the river.

Taken from a nature trail inside the park. There is also a clear view of the statue next to the river.

At the northern edge there is a memorial for those lost on 9/11.

If you have hours to spend, you could also pay admission for the Liberty Science Center. Currently, my family has free admission because of the ASTC Travel Passport Program.

Recession or not, the biggest GDP political football is 3 months away

US GDP fell for the second straight quarter according to statistics released this week by the Bureau of Economic Analysis. This means that by one common definition we’re now in a recession, which has ignited a debate about whether “two consecutive quarters of negative GDP growth” is the best definition (as opposed to ‘when the NBER says there’s one’, like I generally teach and Jeremy argued for here, or something else).

Naturally this debate has political overtones, since the party in power would be blamed for a recession, so we’ve seen the White House CEA argue that we’re not in a recession, many on the other side argue that we are, and plentiful hypocrisy from people who should know better.

But in political terms, the fight over the binary “are we in a recession” call won’t be the big economic factor in November’s elections- that will be inflation and GDP, especially 3rd quarter GDP. One of the oldest and best predictors of US elections is the Fair Model, which uses inflation and the number of recent “strong growth quarters”. Fair’s update following the recent Q2 GDP announcement states:

the predicted vote share for the Democrats is 46.70, which compares to 48.99 in October. The smaller predicted vote share for the Democrats is due to two fewer strong growth quarters and slightly higher inflation

By Election Day we’ll have 3 more months of economic data making it clear whether inflation is getting under control and whether economic activity is picking back up or continuing to decline. Monthly data releases on inflation and unemployment will be closely watched, but the most discussed release will likely be third quarter GDP. It will summarize 3 months instead of just one, it will be of huge relevance to the debate over how severe the recession is or whether we’re even in one, and it will likely be released less than two weeks before election day. The NBER almost certainly won’t weigh in by then; they tend to take over a year to date recessions, not adjudicate debates in real time.

So when BEA does release their Q3 GDP estimate in late October, what will it say? Markets currently estimate at least a 75% chance it will be positive (they had estimated a 36% chance of positive Q2 GDP just before the latest announcement). That sounds high to me, the yield curve is still inverted and I bet investment will continue to drag, but forecasting exact GDP numbers is hard. Its a much easier bet that whatever the number turns out to be will loom large in political debates just before the elections. Perhaps we’ll get the Q3 GDP growth number that would make for the most chaotic debate: 0.0%.

Dating Recessions: 19th Century Edition

Last week my post was on the definition of a recession and argued against using the “two quarters of declining GDP standard.” Little did I know that the very next day, the White House’s Council of Economic Advisors would write a blog post on this topic the very next day (essentially taking the same position as I did). The CEA post set off a long discussion on Twitter, which even spilled over into the national media.

I don’t want to get into that debate here today. Instead, let’s look at the history of dating business cycles, specifically in the 19th century. Forget waiting a few months or even a year for an official NBER announcement: the first attempt to date business cycles was going back over 100 years! In going over this history, perhaps we can learn something about our current debates over recessions, but I think the history is interesting in its own right (it’s also a great example of how we can get better data and use it to answer important questions).

I’ll give a brief history here, but read this Romer and Romer conference paper to get an excellent, full history of the NBER’s business cycle dating. The NBER was essentially found as an institution to study business cycles. One of the first major publications was Willard Thorp’s Business Annals, published in 1926. It was groundbreaking study, which not only provided annual business cycle dates for the entire history of the US, it also did so for 16 other countries for roughly the same time period!

While such an undertaking was impressive, the methods used were pretty unsophisticated from the hindsight of almost 100 years later. First, these are annual estimates, not monthly or even quarterly. Monthly estimates would come later, first appearing in Burns and Mitchell’s 1946 volume Measuring Business Cycles. Those monthly estimates began in 1854, and there are the same ones you will find on the NBER website today, essentially unmodified by even a single month for the late 19th century.

But what of the first half of the 19th century? How did Thorp date recessions?

Is the Bottom Quartile Already in Recession?

I heard on a radio interview that spending by the bottom quartile is way down in 2022, while it is holding up merrily for the upper two quartiles. My mind jumped to the thesis:

“Hmm, the bottom quartile probably (proportionately) felt the benefit of the three COVID stimulus packages more, plus they would have benefited more, proportionately, from the enhanced 2020-2021 unemployment benefits, which (I gathered from anecdotal observations) often paid them more for staying home than they used to receive for working. But…by 2022, all that extra money may be running out.”

I spent some time poking around the internet, trying to find some pre-made figures or tables to support or disprove this thesis. What I found tended to support it, but this is not rigorous data-mining. So, for what it is worth, here are some  charts.

First, about the spending in 2022. This chart indicates that discretionary service spending by the bottom 40% income cohort is indeed down sharply in  2022, and now sits a little lower than a  year ago, while the upper 20% cohort is spending actually more than a year ago.  Spending by the middle 40% trended up in 2H 2021, then back down in 1H 2022, to end about even over the past 12 months:

Discretionary service consumption by income cohort. (I don’t what the units are for the y-axis, but presumably they show the trends). Source: Earnest Research, as of June 30, 2022, as reproduced by Blackrock.

And what about 2020-2021? The next two charts indicate (a) that consumer spending was HIGHER in 2021 that it was pre-COVID for the bottom income quartile, even though (b) their employment in 2021 remained some 20% LOWER than pre-COVID. Looks to me like a lot of spending of stimmie checks was going on in 2021, but (see above) that money has run out in 2022.

Some reader here may have access to a more consistent data set, so I am happy to see this thesis tested further.

How many of our problems come from captured land value?

I can’t shake the idea that captured land value serves as the origin, or at least accelerant, of a great deal of the problems in the United States. What if the YIMBY vs NIMBY fight is just the most visable element of the core economic disease in America? A heads up, if you’re expected a deeply researched 5,000 word post that will YIMBY “pill” your most skeptical colleague, make your peace with disappointment now. But if you’re into policy failures and run-on sentences, you’re in for a good time.

I just can’t get over how often the examination of seemingly every subpar economic context (not immediately attributable to a pandemic or war) comes down to people X are geographically constrained, they need to be proximate to a specific physical location to produce or consume Y, and a huge amount of the economic surplus that would be created from any sort of exchange is captured by land/property owners because legal constraints on development have made the physical place in which an exchange happens THE short side of nearly every market that is pointed to as a failing institution.

Seriously, go through the list of everything that leaves critics of markets ready to burn capitalism (and its fostering society) to the ground. Wages are too low relative to rent. Rent is too high in the places that are near the jobs I want. Public schools aren’t good enough unless you’re willing to carry a mortage that would account for 70% of your take-home pay. Healthcare…eh, maybe not healthcare. Healthcare is crappy for its own bespoke and byzantine set of reasons.

I am a person with no shortage of bodily ailments because I chose to play lots of sports despite never being especially good at them. As a result, I am an avid consumer of physical therapy and therapeutic massage. I have had many conversations about the economics of these fields, and I am now 100% certain that the key to making a career at either, given a minimal level of competence, is not how good you are at your job, but your capacity and good fortune in solving your real estate problem. The entire Massage Envy empire appears to exist not based on greater competence in technique, training, or personnel. It exists solely to extract rents from employees because scale lets them solve the real estate problem (and probably pool liability risk, too). The single biggest thing an individual professional can do to increase their yearly income is not win an award for Therapist of the Year or get 5 stars on Yelp. It’s buying a house with a room they can use as a home office, where they can pay “rent” to themselves and take a tax deduction for the office.

I was once told a likely apocryphal story (that I can’t find on the internet, so it’s probably not true) that the then CEO of Starbucks declared “We make coffee, but we’re in the real estate business.” That their business had matured to the point where revenues could be projected with sufficient accuracy that the profitability had been reduced to identifying opportunities in the real estate market. I don’t know if that ever happened, but that still seems about right to me.

Housing costs hold a special place in how we view our own economic status and security going forward, in part because food costs have been reliably low for so long (knocks on all of the wood). When the rent goes up we feel worse off, not just because we have less disposable income today, but because it increases our expectations for future rent increases as well. We have lots of words for economic insecurity and desperation, but nothing quite makes your blood run cold like the prospect of being homeless, even for the briefest moment.

The phrase “paying your nut” is a lot less common these days. You usually only hear it from self-employed people who live off of a la carte incomes, either in entertainment, freelance, or contracting work. It refers to the minimum amount you have to earn in a month to avoid significant consequences, usually the aggregate of rent/mortgage, utilities, and debt payments. Economists talk about “nominal” and “real” incomes to account for the changes in prices people face. Sometimes there is discussion of “money illusion” where people living under inflation are fooled by higher take-home pay into thinking they’ve become richer. I’ve never been persuaded that nearly anyone suffers from money illusion, nor do I think folks track national price indices and growth statistics.

I think people just know whether it’s easier or harder to pay their nut, and the simplest version of that is the ratio of their take home pay to their rent. Paycheck divided by rent, full stop. If you follow this blog or Jeremy on twitter, you’ll know that one of the puzzles frequently revisited is why Americans are so pessimistic about the economic dynamics of the last 20 to 30 years, and why younger people seem terribly aggrieved about their relative economic status.

So if generational income is fairly consistent and median home mortages account for a slightly declining fraction of median income, what gives? Well, it could all be one big economic mass hysteria, but I’ve got a simpler explanation: the ratio of rent to income to has skyrocketed in the places that young people want to live. Maybe I’m overprojecting my own lived experience, but when I was 25 I did not want to live in a rural area, the suburbs of a major city, or even the downtown of a minor city. I wanted to live in a proper big city. And for a young person, that means living in a small apartment, possibly with roommates, which is exactly the kind of housing places like California stopped building.

Why do so many young people seem pessimistic? Putting aside the absolute failure of politics to produce meaningful climate policy, the simplest explanation is that they have an unpleasant choice. They can live in the same places young people have always lived, only absent any possibility of savings and economic security. Or they can be dispersed from the cultural and economic capitals of our country, and try to build social networks without the benefits of the generational density, plethora of events, and dating markets that have been the hallmark of being a young person in the city since World War I (if not longer).

What will solve this? Policy? California has showed some glimmers of hope. Young people voting with their feet, moving to the shining middle-sized cities that are allowing for growth and affordable rents? Could be, but critical mass is real and growing into a proper metropolis takes decades. Work from home?

That’s interesting enough that I’ll write about it next week. I have thoughts and policy prescriptions, in case any major city is looking for a czar of housing policy (NB: I’m not qualified, but available).

Drone Racing is Poised to Grow

  1. Observations from the World Games

Drone racing was an event at the World Games in my city. Now I know it exists (as does canoe polo!).

The composition of contestants was interesting. One pilot was only 14 years old, the youngest person competing in the 2022 World Games. Another pilot was in a wheelchair. Drone racing is for sports like Work From Home is for professional jobs – the number of competitors is potentially enormous.

Spectators reported that it was hard to follow the actual drones with your eyes. People in the stadium for the race usually watched the jumbo screens that show the point of view of the pilots. This raises the question: why bother with the drones at all when we could just be doing e-sports? There is something special about the extra challenge of a physical race. The machinery adds a NASCAR-like element, and it gives people an excuse to gather together.

Videos, if you’d like to get a sense of how the sport works:

Championship Race: Xfinity CA Drone Speed Challenge, 2018

Maine drone racer heads to the World Games

2. Thoughts on the Future

Polaris published an industry report that predicts growth.

Drone racing will grow in the United States. This seems like a sport that will appeal to Generation Alpha and their parents.

As a parent, I would support it. It’s expensive, so that’s going to be prohibitive for a while, but millions of Americans bought drones at some point in the last decade. Drones get broken in races, but the cost of components is coming down. Part of the sport is being able to repair and build your own custom drones.

A handful of US high school already have drone racing clubs. Adults will be able to point to the value of learning technology that comes along with racing for fun.

Trial Updates: Novavax Approved, Potatoes Work

I’m usually the one writing the papers, but I recently did two studies as a participant / guinea pig. Both just released major positive updates.

I joined the Novavax trial in late 2020 to have the chance to get a Covid vaccine sooner; at the time Pfizer had just got emergency approval but wasn’t available to the general public. The smart bio people on Twitter also seemed to think it was likely to be safer, and perhaps more effective, than other Covid vaccines (it delivers relevant proteins directly, rather than using mRNA or a viral vector). The trial results were published over a year ago now, and were in fact excellent:

Results from a Phase 3 clinical trial enrolling 29,960 adult volunteers in the United States and Mexico show that the investigational vaccine known as NVX-CoV2373 demonstrated 90.4% efficacy in preventing symptomatic COVID-19 disease. The candidate showed 100% protection against moderate and severe disease

As usual the FDA dragged its feet, even as other agencies around the world like the European Medical Agency and the World Health Organization approved the US-made Novavax. But last week it finally gave emergency authorization, and yesterday the CDC recommended Novavax. Of course, by now almost everyone who wants a Covid vaccine has one, and this approval is only for adults. But this will be a great option for boosters, as well as for anyone who was genuinely just concerned with the new technologies in the other vaccines (rather than just afraid of needles, or preferring to cut off their nose to spite authority’s face). As the CDC put it:

Protein subunit vaccines package harmless proteins of the COVID-19 virus alongside another ingredient called an adjuvant that helps the immune system respond to the virus in the future. Vaccines using protein subunits have been used for more than 30 years in the United States, beginning with the first licensed hepatitis B vaccine. Other protein subunit vaccines used in the United States today include those to protect against influenza and whooping cough….

Today, we have expanded the options available to adults in the U.S. by recommending another safe and effective COVID-19 vaccine. If you have been waiting for a COVID-19 vaccine built on a different technology than those previously available, now is the time to join the millions of Americans who have been vaccinated

I’m glad I was in this trial- I got a Covid vaccine several months before I otherwise could have, I made a few hundred dollars, and I learned a lot. But it would have been much better if they found a way to do fewer blood draws, and if FDA approval had come quicker. I’ve been in a weird gray area with respect to vaccine mandates for the last year; almost everyone ended up accepting my vaccine card, but I never knew if they were going to say “no, you need an FDA approved one”. I ended up getting Pfizer for a booster even though I think it’s a worse vaccine, partly for this reason, and partly because Novavax said they’d only give me the booster if I did another blood draw and I was tired of that.

The all-potato diet trial I wrote about here also released its results this week. This trial was much less formal, much smaller, and had no control group, so the results aren’t a slam-dunk the way Novavax is. But I think they’re still impressive. I lost 8 pounds in the 4-week trial, but it turns out the average participant who did all 4 weeks did even better:

Of the participants who made it four weeks, one lost 0 lbs…. Everyone else lost more than that. The mean amount lost was 10.6 lbs, and the median was 10.0 lbs.

Their summary also explains other costs and benefits of the diet, showing lots of data as well as many quotes from participants, including two from me. They conclude with some fascinating speculation about potential mechanisms from the boring (literally, lower variety makes eating boring so you eat less) to the speculative (low lithium? high potassium? weird lithium-potassium interactions), check it out if you’re interested in why obesity rates keep rising or if you’re considering doing the potato diet.

I’m glad I was in these two trials- what to try next?

Are We in A Recession?

The truth is, we don’t know. But let’s be clear: whether we are or not doesn’t depend on the 2nd quarter GDP report. Though two consecutive quarters of declining GDP is often cited as the definition of a recession, it’s not the definition economists use. And with good reason.

Instead, the NBER Business Cycle Dating Committee uses this definition: “a significant decline in economic activity that is spread across the economy and that lasts more than a few months.” And they explain why GDP is not their preferred measure, which includes several reasons but this one seems most germane to our current moment: “[the] definition includes the phrase, ‘a significant decline in economic activity.’ Thus real GDP could decline by relatively small amounts in two consecutive quarters without warranting the determination that a peak had occurred.”

If not GDP, what do they look at? I’ll get into more detail later, but in short, they look at monthly measures of income, consumption, employment, sales, and production (a direct measure of production, which GDP is not — it’s a proxy).

However, the American public seems convinced that we are in a recession. The most recent poll I can find on this is from mid-June, which is useful because (as we’ll see below) we have most of the relevant measures of the economy for June 2022 already. In that poll, 56% of Americans say we are in a recession. And while there is some partisan bent to the responses, even 45% of Democrats seem to think we are in a recession. For those that say we are in a recession, 2/3 cite inflation as the primary indicator that we are in a recession.

Already here we can see the difference between the general public and NBER: the rate of inflation is not one of the measures that NBER considers when defining a recession. So, what are the measures they use?
