Firearms, research, and controlling the narrative

I was happy to see the Wall Street Journal write a staff editorial about my recent paper with Patrick Warren, “Firearms and Lynching“.

I was made aware of the editorial on Saturday and I’ll admit I was a little nervous when I first clicked, only to be relieved to find an accurate summary of the research and a relatively restrained commentary.

But why was I nervous, you may ask. Isn’t media attention something scholars want? Yes. Earlier in my career, that was an unqualified “yes”, but I’ve been doing this long enough now that I appreciate just how little control a scholar has over the conversation that can happen around their work. I’ve had a couple papers get non-trivial media attention over the years and each time it’s a reminder that the research itself is not just the subject of a conversation, it’s a prop that gives people an opportunity to have the conversation they already wanted to have. The findings of the research in question can prove quite immaterial to that conversation.

When I posted a thread about the paper two weeks ago, I was happy to see enough retweets to pass the paper around and get it some attention.

What was less fun was the predictably over-reductive quote tweets and comments excitedly parading the paper as evidence of “guns are good.” Not unlike people excited to reduce a paper to “minimum wages are good” (or “this paper is bad because minimum wages are bad”), it can be frustrating to try to make a nuanced contribution towards understanding a complex context, only to see it reduced to a television debate chyron.

The key to surviving this process is accepting that a scholar, even those of tremendous standing inside and outside of the academy, has little to no control over the narrative that emerges around their work. Holding strong preferences over the surrounding narrative is folly varying only in consequences. You can try to fight the narrative, which typically results in the world either ignoring you or, worse, joyfully inviting you to wrestle in the mud. [Good rule of political discourse: never wrestle with a pig. You can’t win, you end up covered in mud, and the pig loves it.] Some scholars, though not as many as the more skeptical fear, prefer to shape the research to serve a narrative from the outset. This, of course, is no longer research, it’s advocacy masquerading as science. Don’t do this. And lastly, some create great research, only to apologetically bear the burden of the unintended narrative that emerges around their work. If you recognize yourself in this description, my only advice is a) don’t apologize and b) go easy on the sauce.

For what it’s worth, my view of “Firearms and Lynching”, in the context of the broader literature on firearms and public safety, is that things have to be horrifyingly bad before greater availability of firearms make for a safer public. Foreign invasions, institutionalized segregation, pogroms, lynch mobs, these are all contexts where an armed population can make for a better outcome. Probably not a happy ending, but maybe a less tragic one. The Jim Crow South was such a context. That’s how bad it was. That’s the takeaway.

If you want to translate this piece of historical research as evidence that a greater saturation of firearms in modern American society will make for better and safer lives, then I’ll admit that I think you are too pessimistic about the current state of the world. You’ve spent too much time reading about burning cities that actually aren’t burning. If you think that a greater taking up of arms by Black Americans will make their lives safer and better, then I’ll admit I still think that is probably wrong, but maybe less wrong. Black Americans have brought their reality to the eyes of broader America and that reality questions whether or not the police serve their communities or threaten them. It is certainly a legitimate question whether they can rely on police protection to secure their homes and their communities.

It doesn’t take a lot of imagination to make the next logical leap here. If police can’t be counted on, we’ll protect ourselves, and firearms are a tool to do that. That sort of thinking, however, is exactly why making leaps from history to contemporary contexts is so fraught. As bad as things are today, even in the most violent districts with the most contemptable police departments, it’s not the Jim Crow South. Lynch mobs are not roaming the streets and selling photos of their victims as postcards. Groups of young white men are not wandering into homes and stealing from them without fear of retribution. Firearms are tools of death, and their presence bring benefits and costs. To exceed the costs of broadly deadlier conflict throughout your community, the benefits to other dimensions of public safety have to be significant.

And we’ve haven’t even confronted the additional reality that an armed Black man in the United States should probably not feel safe in the presence of a police officer, no matter if that firearm is licensed, registered, and transparently revealed to the officer. In a land of no-knock raids, where police are bursting into homes under cover of night with fingers on triggers, I’m not sure a more heavility armed Black America leads to fewer men and women being killed by police.

I’m sorry, did you think that I was going to close out this post with a solution to modern violence and policing in America? With an answer? The world is complex and difficult, policy for it doubly so. My colleague and I wrote a paper that tried to answer the question of whether a minority living under an indifferent regime that condoned terrorism could better live their lives armed. That’s the question we made a contribution towards answering, and our results point towards “Yes”. If you want me to make big claims about what that means today, well, get used to disappointment.

Recent Podcasts about Data Analytics

My students recently assembled a list of podcasts about data analytics that are a click away if this is a topic of interest.

The show they pulled from the most was In Machines We Trust produced by the MIT Technology Review.

“Attention Shoppers, You’re Being Tracked“

“Hired by an Algorithm” (“I would recommend this podcast to anyone who will be applying for a job in the near future.”)

“Encore: When an Algorithm Gets It Wrong”

“Can AI Keep Guns out of Schools“

“How retail is using AI to prevent fraud“

Other episodes, not from In Machines We Trust:

The Shrinking Allied Social Science Association

For many decades the Allied Social Science Association (ASSA) meetings, anchored by the American Economic Association, have been by far the world’s largest gathering of economists each year, typically attracting well over ten thousand. But the meetings went virtual-only for the past two years, and when they finally return in-person in 2023 they will likely be substantially diminished.

Some of this is due to potentially one-off factors; some people don’t want to travel to Louisiana because of its state laws, some still want to avoid large conferences because of Covid, others want to avoid the ASSA’s response to Covid:

All registrants will be required to be vaccinated against COVID-19 and to have received at least one booster to attend the meeting…. High-quality masks (i.e., KN-95 or better) will be required in all indoor conference spaces.

But the AEA made one big, apparently permanent change that means it could be a long time before we see a meeting as big as January 2020’s in San Diego- they gave up the job market. Prior to Covid the vast majority of first-round interviews to be a full-time US economics professor took place at ASSA. Naturally interviews moved online during Covid, but surprisingly the AEA has asked that they stay online, and in fact has specifically asked schools NOT to schedule interviews during ASSAs. This removes a huge source of demand for the meetings- the ~1200 new PhDs looking for their first jobs, the thousands of people there to recruit them (each hiring school typically sends 2-4 interviewers), and everyone trying to switch jobs. This was THE big thing that made AEAs special, that other conferences didn’t really have.

I’ll let everyone else debate whether this makes the job market better or worse; I’m agnostic there, but I’m sure it will shrink the conference. One silver lining to a smaller conference is that it is much easier to find a hotel room. Like usual I was waiting on the AEA website this Tuesday to book a hotel room on the first minute the AEA’s deeply discounted hotel blocks opened, because the good hotels tend to fill up near-instantly. But it appears this was unnecessary this year- two days later and even the headquarters hotel is still wide open:

I got the room I wanted at the Hotel Monteleone; I’ll be looking to grab a spot on the Carousel Bar, maybe see some of you there. I’ll present a poster at AEA, but mostly I’m just looking forward to spending real time in New Orleans for the first time since I moved away in 2017.

Yes, it rotates while you sit and drink

So I’m still looking forward even to a diminished AEA, but it does make me wonder- which other conferences will benefit most from AEA’s decline? I don’t know that anyone has put together the numbers for all the conferences enough to know what the 2nd-largest is, but my bet both for the 2nd-largest and most likely to benefit is the Southern Economic Association; I’ll be there too, in Ft. Lauderdale this November.

Grocery Prices and Wages, in the Short Run and the Long Run

From the recent CPI inflation report, one of the biggest challenges for most households is the continuing increase in the price of food, especially “food at home” or what we usually call groceries. Prices of Groceries are up 13.5% in the past 12 months, an eye-popping number that we haven’t seen since briefly in 1979 was only clearly worse in 1973-74. Grocery prices are now over 20% greater than at the beginning of the pandemic in 2020. Any relief consumers feel at the pump from lower gas prices is being offset in other areas, notably grocery inflation.

The very steep recent increase in grocery prices is especially challenging for consumers because, not only are they basic necessities, if we look over the past 10 years we clearly see that consumer had gotten used to stable grocery prices.

The chart above shows the CPI component for groceries. Notice that from January 2015 to January 2020, there was no increase in grocery prices on average. Even going back to January 2012, the increase over the following 8 years was minimal. Keep in mind these nominal prices. I haven’t made any adjustment for wages or income! (If you know me, you know that’s coming next.) Almost a decade of flat grocery prices, and then boom!, double digit inflation.

But what if we compare grocery prices to wages? That trend becomes even more stark. I use the average wage for non-supervisory workers, as well as an annual grocery cost from the Consumer Expenditure Survey (for the middle quintile of income), to estimate how many hours a typical worker would need to work to purchase a family’s annual groceries. (I’ve truncated the y-axis to show more detail, not to trick you: it doesn’t start at zero.)

Saving a Rusted Car with Rust Bullet Paint and Cosmoline RP-342 Coating

Corrosion is estimated to cost about $250 billion per year in the U.S. alone, so it is economically significant. The impact of corrosion hit home for me when I noticed that near the bottom of the right rear wheel well of my little 2007 sedan, a 2-3” hole had rusted right through the metal, exposing some inner chambers to water and salt and sand thrown from the wheel. The rust does not look like it has compromised the vehicle’s mechanical integrity (a real concern, since today’s cars rely on the body sheet metal for strength), but if it keeps on going it could turn my chariot into a junker.

I called an honest local body shop, and the guy told me it would probably cost more than the car is worth to fix it properly (replace the rocker panels, etc.), and  it might run $1700 just to do a patch job.

Being a (retired) chemical engineer, I decided to read up on ways to deal with rusting metal. Especially, how to arrest the progress of rust. The most serious way is to do major surgery with cutting tools, and cut out all the rust, and weld good metal back in, and paint it all well. That is out of my league. So I looked for coatings that could stop the rusting progress.

I have written an article on a different blog describing the various classes of coatings and rust converters that are available. For my project, I chose to use Rust Bullet, ordered from Amazon.

This can be painted directly on rusty metal surfaced, after scraping away all the loose rust. This stuff chemically reacts with the remaining surface rust to make it more inert, and also forms an impermeable seal over the surface, to block further water and oxygen from reaching the metal. It sticks to rusty and non-rusty surfaces. It seems to get good reviews.

One peculiarity of Rust Bullet is that if many hours have elapsed after application its surface gets so smooth that that that the next layer of Rust Bullet or top coat paint will not stick unless you sandpaper the smooth, hard, silvery surface. It’s easiest, therefore, to leave only 2 hours or so between coats of paint, to avoid the bother of sandpapering.

After two coats of Rust Bullet, I applied a top coat of Rustoleum enamel paint (white on the outside of the car, black on interior surfaces).

Some rust had started on surfaces of the inner chambers of sheet metal that had been exposed by the rusted-out hole. I could not readily reach them with a paint brush to apply Rust Bullet. I wanted to spray something that would form a coating that would inhibit further rusting. I settled on Cosmoline RP-342, ordered from the manufacturer.

This stuff sprays on like a thick oily liquid, that should soak into any rust. After maybe 2 hours, it hardens up to a very impermeable, fairly tough waxy coating. It will keep water off surfaces, though I don’t know about oxygen. Anyway, I sprayed the Cosmoline into the available openings, to try to coat the surfaces of the inner chamber parts. (If I had known about it in time, I might have chosen Eastwood Internal Frame Coating instead of Cosmoline for this step.) I was able to coat most, though not all, of the vulnerable surfaces. This was all with me lying on my side, beside/under the car, without great ergonomic access.

I then used several layers of aluminum foil duct tape (learned this trick from YouTube) to seal up the holes in the car body, then added a final coat of white or black Rustoleum. This has pretty well protected the car body there from further exposure to water/sand/sand. It should give me a couple more years of use, all for two days of picky handwork plus the cost of materials.

Welcome to Wrexam

I want to write about the economics of the Wrexam football club. They have docu-series currently airing on FX weeking until late October. They have two celebrity owners whose level of wealth falls squarely within the range of optimum dramatic tension i.e. rich enough to buy and improve a tiny Welsh football club, but so rich that they can buy their way out of every problem without utterly ruining themselves and their families.

I want to write about it, but I won’t. I’ll be patient and wait until the first season is over. Instead, I want to encourage you to watch all or part of the season with an eye towards the drama and risk there is to be found in solving such a complex economic problem. Pay attention, there will be a quiz in two months:

  1. How do you optimize your committment to an investment whose financial payoff is gaining access to a higher revenue stream via a process as unpredictable as finishing at or near the top in a 24 team football league? How do you cope with that much noise in a system with such poor underlying odds?
  2. How do you optimize your committment to an investment whose payoff has an enormous non-pecuniary element (i.e. joy from the success of the team) and that non-pecuniary element is a true local public good (non-excludable and non-rival) that represents a significant portion of total utility in local households?
  3. How should local stake holders treat their relationship to the team? The supporters group has significant voting power when transitioning ownership. What should they be maximizing when they cast their votes? On what observables should they base their decisions?
  4. In what ways are the owners failing to optimally allocate resources within the team?
  5. In what ways is the manager and coaching staff failing to optimally manage the player resources they have?
  6. Are incentives aligned top to bottom in the organization? Within the team?
  7. How do you measure success and failure with a sports club? Should these metrics, or the relative weights on these metrics, change with the scale of the club, it’s resources, and its fan base?

When the season is over we will revisit these questions and more. Running a sports team is an incredibly complex problem to solve. Most previous inside looks have been pure PR projects for the very biggest clubs, worth billions of dollars. These clubs/teams are enormous enterprises, with vast hierarchies and narrowly divided tasks. They are in many ways simply too big to fit into frame for an intimate documentary. If that’s what you’re interested in, fiction is the better channel because it can abstract away from all the field maintence and beer pricing, and just show you Brad Pitt cutting deals over the phone while stuffing food into his beautiful face.

To really understand this business from the inside, you gotta go small. To places where a small number of individuals are making an inefficiently vast range of decisions. Welcome to Wrexam so far looks to be one of the very best views into that world. I can’t wait to see more.

I just hope they find someone to update their zonal marking system on set pieces. I don’t know, maybe much some YouTube videos or something. Yikes.

Patrick Henry Blog

I wrote about Patrick Henry for OLL this week.

“Can [the President] not at the head of his army beat down every opposition? Away with your President, we shall have a King: The army will salute him Monarch; your militia will leave you and assist in making him King, and fight against you: And what have you to oppose this force? What will then become of you and your rights? Will not absolute despotism ensue?” It is noted in the manuscript that the stenographer could not keep up with the torrent of terrible possible consequences that Henry was shouting about concerning a chief executive.

Most of his apocalyptic scenarios have not happened … yet. What inspired me in his speech was his energy more than his arguments. As much as he praised the American spirit of the past that ousted British rule, he was not complacent. He models a kind of patriotism that embraces an American project without holding to any fantasies about the morality of particular American leaders or soundness of American institutions. He would not have been disillusioned by the scandals and crimes of the American political class. He anticipated it.

McDouble vs Big Mac: Why Inflation Hits the Bottom Harder

Since they were first introduced as part of the Dollar Menu in 1997, the McDouble and the McChicken have been my go-to choices when I visit Mcdonald’s. It was always hard to justify getting one of the fancier sandwiches like a Big Mac or Quarter Pounder, since they were 4-5x the cost of a McDouble but only about twice the size. This is part of why the McDouble has been called “the greatest food in human history“. But as we’ve seen with the plagues and wars of the 2020s, history doesn’t always progress in the direction you’d hope.

I hadn’t been to a McDonald’s for a while until last weekend, when I was shocked to see the McDouble and McChicken listed at $2.99. This wasn’t at an airport restaurant either, or even in an expensive big city; I stopped in Keene, New Hampshire on a drive home from Vermont. The price is up 200% from the days of the Dollar Menu! Meanwhile, the Big Mac has also got more expensive, but much less dramatically; it was $5.89, compared to the ~$5 I expect. So, 200% price increases at the bottom, vs 18% at the top.

This location may be a bit of an anomaly, but the big picture is clear; a typical McDouble now costs well over $2 in most of the US, while a typical Big Mac is still well under $6. You used to be able to get 4-5 McDoubles for the price of a Big Mac; now you typically get less than 3 and sometimes, as in Keene, less than 2.

What’s going on here? First, the McDouble was always absurdly cheap. Second, prices rise most quickly where demand is inelastic, and demand is less elastic for goods that are cheaper and goods that are more like “necessities” than “luxuries”.

This is why I think the McDouble is worth highlighting- its part of a more general trend of where inflation hits. I’ve noticed this in the grocery store as well; the price of standard ground beef is up much more than grass-fed organic beef, likewise with standard eggs vs free-range organic. How different would the Economist’s Big Mac Index look if it used the McDouble instead?

With falling inflation we may see the end of this necessity vs luxury price compression. But I doubt we’ll ever see the glory of the standard $1 McDouble again.

The New Hampshire McDonalds was disappointing, but Vermont was nice

The Cost of Raising a Child

Raising kids is expensive. As an economist, we’re used to thinking about cost very broadly, including the opportunity cost of your time. Indeed, a post I wrote a few weeks ago focused on the fact that parents are spending more time with their kids than in decades past. But I want to focus on one aspect of the cost, which is what most “normal” people mean by “cost”: the financial cost.

Conveniently, the USDA has periodically put out reports that estimate the cost of raising a child. Their headline measure is for a middle-income, married couple with two children. Unfortunately the last report was issued in 2017, for a child born in 2015. And in the past 2 years, we know that the inflation picture has changed dramatically, so those old estimates may not necessarily reflect reality anymore. In fact, researchers at the Brookings Institution recently tried to update that 2015 data with the higher inflation we’ve experienced since 2020. In short, they assumed that from 2021 forward inflation will average 4% per year for the next decade (USDA assumed just over 2%).

Doing so, of course, will raise the nominal cost of raising a child. And that’s what their report shows: in nominal terms, the cost of raising a child born in 2015 will now be $310,605 through age 17, rather than $284,594 as the original report estimated. The original report also has a lower figure: $233,610. That’s the cost of raising that child in 2015 inflation-adjusted dollars.

As I’ve written several times before on this blog, adjusting for inflation can be tricky. In fact, sometimes we don’t actually need to do it! To see if it is more or less expensive to raise a child than in the past, what we can do instead is compare to the cost to some measure of income. I will look at several measures of income and wages in this post, but let me start with the one I think is the best: median family income for a family with two earners. Why do I think this is best? Because the USDA and Brookings cost estimates are for married couples who are also paying for childcare. To me, this suggests a two-earner family is ideal (you may disagree, but please read on).

Here’s the data. Income figures come from Census. Child costs are from USDA reports in 1960-2015, and the Brookings update in 2020.

Putin as the New Hitler: The Russian Political Philosophy Which Justifies Unlimited Atrocities (To Save the World)

When the Nazis in the mid-twentieth century carried out schemes to kill millions of people (soldiers and civilians), they did not say, “Yes, we are evil, but we have the most guns.” Rather, they espoused a political philosophy to justify their actions. According to this Wikipedia entry, the Nazis held that they were simply carrying out normal, healthy, natural selection (the strong eliminating the weak) by having the “superior” race kill and displace the inferior races of humans. Germans therefore felt justified in occupying lands in Eastern Europe, Russia, and Ukraine, to provide “living space” and agricultural production for the master race.

It seems that a somewhat similar political philosophy has taken hold among Russian elites. This became evident early on in Russia’s 2022 invasion of Ukraine, when the Russians bombed a children’s shelter and a maternity hospital. Since then, there have been innumerable bombings of apartment buildings, shopping malls, etc., as deliberate murderous attacks on civilians, rather than having any direct military benefit. The Russians are killing  Ukrainians with the sort of callous abandon displayed by the Nazis towards “undesirables”. The initial Russian complaints about Ukraine joining NATO have disappeared; it is clear that Russia wants to simply erase Ukraine as an entity. It seems that this has been Russia’s plan under Putin for many years. Reportedly, Russian textbooks since around 2014 have deleted discussion of Ukraine as a separate nation.

Where did this toxic outlook come from? According to many observers, a chief architect for this view is political philosopher Aleksandr Dugin. German professor Antony Mueller has summarized some of Dugin’s positions:

Russians are “eschatologically chosen.” They must stand against the false faith, the pseudoreligion of Western liberalism and the spread of its evil: modernity, scientism, postmodernity, and the new world order. This is the thesis of Aleksandr Dugin, the prominent Russian philosopher, and a mentor of the Russian president Vladimir Putin…His theory is a “crusade” against postmodernity, the postindustrial society, liberal thought, and globalization… For Dugin, America is a threat to the Russian culture and to Russia’s identity. He makes his position unmistakably clear when he declares:

“I strongly believe that Modernity is absolutely wrong and the Sacred Tradition is absolutely right. USA is the manifestation of all I hate—Modernity, westernization, unipolarity, racism, imperialism, technocracy, individualism, capitalism.”

Dugin apparently believes that the world, or at least Eurasia, can only be saved from the ravages of “modernity” and American influence by uniting under Russian leadership  and returning to the Sacred Tradition of “religion, hierarchy, and family.”

An independent Ukraine stands in the way of this grand vision. From the Guardian:

Dugin’s worldview is most clearly articulated in his 1997 publication “The Foundations of Geopolitics”, which reportedly became a textbook in the Russian general staff academy and solidified his transition from a dissident to a prominent pillar of the conservative establishment.

In the book, Dugin laid out his vision to divide the world, calling for Russia to rebuild its influence through annexations and alliances while proclaiming his opposition to Ukraine as a sovereign state.

“Ukraine as a state has no geopolitical meaning, no particular cultural import or universal significance, no geographic uniqueness, no ethnic exclusiveness,” he wrote.

… Twenty-five years later, Russia’s president repeated some of Dugin’s views on Ukraine in his 4,000-word essay “On the Historical Unity of Russians and Ukrainians”, which many saw as a blueprint for the invasion he launched just six months after it was published.

And as far as Ukrainians resisting Russia’s neo-imperial ambitions, Dugin said, “I think we should kill, kill, kill [Ukrainians], there can’t be any other talk.”

There you have it. The exact influence of Dugin on Putin is debated, but there is no doubt that Dugin’s views are influential in the circles of Russian decision makers. Many Westerners thought early on that Putin would be satisfied with conquering the Russian-speaking Donbas region in the east, and a narrow land bridge to connect that with the Russian-occupied Crimea. His attempts, foiled by heroic Ukrainian resistance, to take Kiev and to take Odessa in the southwest showed that he wants the whole enchilada.

This could be a long war.

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

Addendum: Dugin’s daughter was killed by a car bomb near Moscow on August 20, 2022. Reportedly the bomb was aimed at Dugin himself, since he was expected to be in the car with his daughter. Moscow accused Ukraine of the assassination, which Kiev plausibly denies. There is also reasonable speculation that a Russian government agency (presumably with Putin’s tacit approval) was aiming to bump off Dugin, for some Byzantine reason.
