$1 Million or I Quit: CTE Deaths in Football and Hockey

Former teammates of athletes who died of CTE would require $6 million to offset this disamenity and $1 million to be indifferent between exiting and staying in the profession.

So concludes a paper by Josh Martin. I thought this paper would be about a small group, since CTE deaths mostly happen among long-retired players with few or no former teammates still playing. But it turns out there were a fair number of early deaths, and each player had many teammates who can be affected, totaling 23% of NHL players and 14% of NFL players:

But teams mostly won’t pay worried players enough extra to stay, especially in hockey. So many of them retire early:

Athletes who were teammates with a former teammate who died with CTE for three or more years and played for a team with them at least two years before their death are 7.22 percentage points more likely to retire than characteristically similar non-treated players in the same years. Relative to the pre-treatment mean, this represents a 69% increase.

People still respond to incentives though, and if you do pay them enough they mostly take the risk and stay:

The remaining players will take measures to protect themselves, like skipping games to recover from concussions:

Michael previously pointed out here that these concerns matter more for certain positions, like running backs:

If you want millionaires to show up every week to willingly endure the equivalent of a half-dozen car accidents, you’re going to have to pay them.

This all makes for a good illustration of the theory of compensating differentials, which is sometimes surprisingly hard to observe in the labor market. But sports tend to have the sort of data we can only dream of elsewhere. Which other workers have millions of people observing, measuring, and debating their on-the-job productivity and performance?

This summer I was one of thousands of people crowding into Foxborough just to watch them practice:

The NFL season kicks off today, and I say the players deserve the millions they are about to earn.

Older Workers Have Not Dropped Out of the Labor Force

A recent blog post from the St. Louis Fed claims that:

“Both younger and older workers withdrew from the labor force in large numbers during the pandemic: In fact, their participation rates plummeted. Yet, within two years, the younger workers had bounced back to their pre-pandemic participation rates. But the older workers have not.”

They include a chart which seems to back up that assertion:

However, if you look closely, you will see that the older workers’ age group is open-ended. It includes 55-year-olds, as well as 95-year-olds. Given that the US population is aging, this seems like a poor choice.

While not available currently in the FRED database, there is data from BLS available for older workers that is not open-ended. For example, we can look at workers ages 55-64, who are older but still young enough that they are mostly below traditional retirement age. I use that data and compare with the 25-54 age group (note: because the 55-64 data isn’t available seasonally adjusted, I use the non-adjusted data for both age groups, then use a 12-month average, so my chart doesn’t exactly replicate the chart above):

By using a closed-end age group for older workers, we see that labor force participation has not only recovered from the pandemic, but it exceeds the pre-pandemic peak for both prime-age and older workers, and had done so by the Spring of 2023. In fact, both are now about 1 percentage point above February 2020. If we want to go to the first decimal place, older workers have actually increased their labor force participation slightly more: 1.1 vs 0.9 percentage points. But these are close enough, given that this is survey data, to say the recovery has been roughly equal.

The St. Louis Fed blog concludes by saying that early workforce retirements “will continue to depress the labor force participation rate of workers aged 55 and older for the foreseeable future.” But it’s not true that the LFPR of older workers is depressed! Provided that we exclude those 65 and older.

Can the President Fire a Member of the Federal Reserve Board of Governors?

That’s exactly what he tried to do this past Monday. Trump announced on social media that Lisa Cook, appointed by Biden in 2022, is now fired. Things are about to get awkward.

First, Trump can’t simply fire Fed governors willy-nilly. Remember when DOGE was involved in all of those federal workforce lay-offs earlier in the year? I know, it seems like forever ago. The US Supreme Court ruled on the legality of those firings, including some at government corporations and ‘independent agencies’. The idea behind such entities is that they are supposed to be politically insulated and less bound by the typical red tape of the government. But Trump’s administration argued that the separation from the rest of the executive branch is a fiction and that there is no one else in charge of them if not the president. The Supreme Court agreed with the administration, with one exception.

You Read It Here First

The subjects of two of our posts from 2023 are suddenly big stories.

First, here’s how I summed up New Orleans’ recovery from hurricane Katrina then:

Large institutions (university medical centers, the VA, the airport, museums, major hotels) have been driving this phase of the recovery. The neighborhoods are also recovering, but more slowly, particularly small business. Population is still well below 2005 levels. I generally think inequality has been overrated in national discussions of the last 15 years relative to concerns about poverty and overall prosperity, but even to me New Orleans is a strikingly unequal city; there’s so much wealth alongside so many people seeming to get very little benefit from it. The most persistent problems are the ones that remain from before Katrina: the roads, the schools, and the crime; taken together, the dysfunctional public sector.

The New York Times had a similar take yesterday:

Today, New Orleans is smaller, poorer and more unequal than before the storm. It hasn’t rebuilt a durable middle class, and lacks basic services and a major economic engine outside of its storied tourism industry…. New Orleans now ranks as the most income-unequal major city in America…. In areas that attracted investment — the French Quarter, the Bywater and the shiny biomedical corridor — there are few outward signs of the hurricane’s impact. But travel to places like Pontchartrain Park, Milneburg and New Orleans East that were once home to a vibrant Black middle class, and there are abandoned homes and broken streets — entire communities that never regained their pre-Katrina luster…. Meanwhile, basic city functions remain unreliable.

I wrote in 2023 about a then-new Philadelphia Fed working paper claiming that mortgage fraud is widespread:

The fraud is that investors are buying properties to flip or rent out, but claim they are buying them to live there in order to get cheaper mortgages…. One third of all investors is a lot of fraud!… such widespread fraud is concerning, and I hope lenders (especially the subsidized GSEs) find a way to crack down on it…. This mortgage fraud paper seems like a bombshell to me and I’m surprised it seems to have received no media attention; journalists take note. For everyone else, I suppose you read obscure econ blogs precisely to find out about the things that haven’t yet made the papers.

Well, that paper has now got its fair share of attention from the media and the GSEs. Bill Pulte, director of the Federal Housing Finance Agency and chairman of Fannie Mae and Freddie Mac, has been going after Biden-appointed Federal Reserve Governor Lisa Cook over allegations that she mis-stated her primary residence on a mortgage application:

Pulte has written many dozens of tweets about this, at least one of which cited the Philly Fed paper:

Now President Trump is trying to fire Cook. Federal Reserve Governors can only be fired “for cause” and none ever have been, but Trump is using this alleged mortgage fraud to try to make Cook the first.

The Trump administration seems to have made the same realization as Xi Jinping did back in 2012– that when corruption is sufficiently widespread, some of your political opponents have likely engaged in it and so can be legally targeted in an anti-corruption crackdown (while corruption by your friends is overlooked).

I’m one of a few people hoping for the Fed to be run the most competent technocrats with a minimum of political interference:

But I’m not expecting it.

Remember, you read it here first.

The American Middle Class Has Shrunk Because Families Have Been Moving Up

In 1967, about 56 percent of families in the US had incomes between $50,000 and $150,000, stated in 2023 inflation-adjusted dollars. In 2023, that number was down to 47 percent. So the American middle class shrunk, but why? (Note: you can do this analysis with different income thresholds for middle class, but the trends don’t change much.)

The data comes from the Census Bureau, specifically Table F-23 in the Historical Income Tables.

As you can see in the chart, the proportion of families that are in the high-income section, those with over $150,000 of annual income in 2023 dollars, grew from about 5 percent in 1967 to well over 30 percent in the most recent years. And the proportion that were lower income shrunk dramatically, almost being cut in half as a proportion, and perhaps surprisingly there are now more high-income families than low-income families (using these thresholds, which has been true since 2017). The number is even more striking when stated in absolute terms: in 1967 there were only about 2.4 million high-income households, while in 2023 there were 11 times as many — over 26 million.

Is this increase in family income caused by the rise of two-income households? To some extent, yes. Women have been gradually shifting their working hours from home production to market work, which will increase measured family income. However, this can’t fully explain the changes. For example, the female employment-population ratio peaked around 1999, then dropped, and now is back to about 1999 levels. Similarly, the proportion of women ages 25-54 working full-time was about 64 percent in 1999, almost exactly the same as 2023 (this chart uses the CPS ASEC, and the years are 1963-2023).

But since the late 1990s, the “moving up” trend has continued, with the proportion of high-income families rising by another 10 percentage points. Both the low-income and middle-income groups fell by about 5 percentage points. Certainly some of the trend in rising family income from the 1960s to the 1990s is due to increasing family participation in the paid workforce, but it can’t explain much since then. Instead, it is rising real incomes and wages for a large part of the workforce.

Government Makes Quasi-Nationalization Deal to Assure Supply of Critical Rare Earths for Defense 

If top government officials were regular readers of this blog, they would have been warned by a headline here more than two years ago, “China To Squeeze West by Restricting Export of Essential Rare Earths “.  For the last few years, the U.S. has been trying to limit Chinese access to the most powerful computing chips, which are largely made by American company Nvidia. But China has some high cards to play in this game. It produces some 90% of refined rare earths and rare earth products like magnets.  These super-powerful neodymium-containing magnets are utterly critical components in all kinds of high-tech products, including wind turbine generators and electric motors for electric vehicles and drones, and miscellaneous military hardware.

It has been painfully obvious at least since 2010, when China put the squeeze on Japan by unofficially slowing rare earth exports to Japan over a territorial dispute, that it was only a matter of time before China played that card again. But the West slumbered on. There is a reasonable amount of rare earth ores that are mined outside China, but nobody wanted to build and operate the expensive and environmentally messy processes to refine the rare earth minerals (carbonates, oxides, phosphates) into the pure metals. Unlike the esoteric and hard-to-imitate processing for cutting edge computing chips, anyone can gear up and start refining rare earth ores. It mainly just takes money, lots and lots of it, to build and operate all the processing equipment for the multiple steps involved*. There was little free market incentive for a Western company to invest in expensive processing, since China could readily bankrupt them by cutting prices as soon as they started up their shiny new process line. Reportedly, the Chinese used this tactic twice before (in 2002 and 2012) to kill nascent refining of the rare earth ores at Mountain Pass mine in California.

As of April of this year, in response to ongoing U.S. export restrictions on chips, China threw its latest rare earth card down on the table, requiring export licenses and imposing other restrictions that throttled rare earth exports. Western manufacturers were soon howling in pain. As of early June:

Global automakers are sounding the alarm on an impending shortage of rare earth magnets as China’s restrictions on the material vital for the automotive, defence and clean energy industries threaten production delays around the world.

German automakers became the latest to warn that China’s export restrictions threaten to shut down production and rattle their local economies, following a similar complaint from an Indian EV maker last week. U.S., Japanese and South Korean automakers warned President Donald Trump on May 9 car factories could close.

The Trump administration quickly caved on chips and in July permitted boatloads of high-end H20 Nvidia chips to ship to China, in return for resumption of rare earth exports from China. Score one for the CCP. As of mid-August, rare earth shipments had climbed back to around half of their pre-May levels, but China ominously warned Western companies against trying to stockpile any reserves of rare earths, or they would “face shortages” in the future.

After this ignominious face-slapping, the administration finally did something that should have been done years ago: they gave an American company a solid financial incentive to buckle down and do the dirty work of refining rare earth ores at large scale. The Defense Department inked a deal with MP Materials Corp, the current operator of the Mountain Pass mine and the modest refining operation there to quickly ramp up production:

The Department of Defense is investing capital in MP across several fronts. This includes a $400 million convertible preferred equity, struck at a fixed conversion price of $30.03. The government gets 10-year MP stock warrants also set for a $30.03 price. As planned, this would get the Department of Defense to about a 15% ownership position in MP Materials. In addition, the Department of Defense will lend MP Materials $150 million at a highly competitive interest rate to help the company expand its heavy rare earth element separation capabilities.

It’s not just a financing deal, however. This arrangement also provides a striking level of influence over pricing and profitability for MP Materials going forward.

For one thing, the Department of Defense will provide a price floor of $110 per kilogram for NdPr. NdPr is a product that is a combination of neodymium and praseodymium. This is a generous floor price…

The Department of Defense’s involvement now gives MP Materials the runway necessary to build what’s being dubbed the 10X magnet manufacturing expansion plant. The Department of Defense is committed to buying the output of this plant with a controlled cost-plus pricing structure. And there will be a profit split with the DoD getting a significant chunk of the upside above certain EBITDA thresholds.

This is being billed as a private-public partnership, but it is akin to nationalization. The government will be heavily involved in planning output and setting pricing here, as well as sharing in profits.  Fans of laissez-faire free markets may be understandably queasy over this arrangement, but national security considerations seem to make this necessary.

I predict that further “private-public” deals will be struck to subsidize Western production of vital materials. Let’s be clear: massive subsidies or similar incentives, in one form or another, will be needed. And this means that Americans will have to devote more resources to grinding out industrial materials, and less to consumer goods; hence, we will likely live in smaller houses, perhaps (gasp) lacking granite countertops and recessed lighting. Economics is all about trade-offs.

Due to its vast, lower-paid, hard-working and highly-capable workforce, the whole Chinese supply chain and production costs run far, far cheaper than anything in the West. We don’t have to produce 100% of what we use, even say 40% might be enough to keep from being helplessly squeezed by another nation. How to do this without descending into unproductive rent-seeking rip-offs will be a challenge.

Some other materials candidates:  China has as of December 2024 completely shut off exports to the U.S. of three key non-rare earth technical elements, gallium, germanium and antimony, so those might be a good place to start. China mines or refines between half and 90% of global supply of those minerals. Also, China has instituted export regulations of for more key metals (tungsten, tellurium, bismuth, indium and molybdenum-related products), so these may be further subjects for squeeze plays. Finally, “China is the world’s top graphite producer and exporter, and also refines more than 90% of the world’s graphite into a material that is used in virtually all EV batteries,” so that is yet another vital material where the West must decide how much it is worth to break its dependence on an unreliable trading partner.

We Don’t Have Mass Starvations Like We Used To

Two ideas coalesced to contribute to this post. First, for years in my Principles of Macroeconomics course I’ve taught that we no longer have mass starvation events due to A) Flexible prices & B) Access to international trade. Second, my thinking and taxonomy here has been refined by the work of Michael Munger on capitalism as a distinct concept from other pre-requisite social institutions.

Munger distinguishes between trade, markets, and capitalism. Trade could be barter or include other narrow sets of familiar trading partners, such as neighbors and bloodlines.  Markets additionally include impersonal trade. That is, a set of norms and even legal institutions emerge concerning commercial transactions that permit dependably buying and selling with strangers. Finally, capitalism includes both of these prerequisites in addition to the ability to raise funds by selling partial stakes in firms – or shares.

This last feature’s importance is due to the fact that debt or bond financing can’t fund very large and innovative endeavors because the upside to lenders is too small. That is, bonds are best for capital intensive projects that have a dependable rates of return that, hopefully, exceed the cost of borrowing. Selling shares of ownership in a company lets a diverse set of smaller stakeholders enjoy the upside of a speculative project. Importantly, speculative projects are innovative. They’re not always successful, but they are innovative in a way that bond and debt financing can’t satisfy. Selling equity shares open untapped capital markets.

With this refined taxonomy, I can better specify that it’s not access to international trade that is necessary to consistently prevent mass starvation. It’s access to international markets. For clarity, below is a 2×2 matrix that identifies which features characterize the presence of either flexible prices or access to international markets.

What is $300,000 from “The Gilded Age” Worth Today?

SPOILER ALERT FOR THE THIRD SEASON OF THE GILDED AGE

In Season 3 of the drama series “The Gilded Age,” one of the servants (Jack, a footman) earns a sum of $300,000 by selling a patent for a clock he invented (the total sum was $600,000, split with his partner, the son of the even wealthier neighbor to the house Jack works in). In the series, both the servants and Jack’s wealthy employers are shocked by this amount. Really shocked. They almost can’t believe it.

How can we put that $300,000 from 1883 in New York City in context so we can understand it today?

A recent WSJ article attempts to do that. They did a good job, but I think more context could help. For example, they say “Jack could buy a small regional bank outside of New York or bankroll a new newspaper.” Probably so, but I don’t think that quite conveys the shock and awe from the other characters in the show (a regional bank? Ho-hum).

First, the WSJ states that the “figure nowadays would be between $9 and $10 million.” That’s just doing a simple inflation adjustment, probably using a calculator such as Measuring Worth (it’s a good tool, and they mention it later in the story). But as the WSJ goes on to note, that probably isn’t the best way to think about that figure.

Here’s my best attempt to contextualize the $300,000 figure: as a footman, Jack probably made $7 to $10 per week. Or let’s call it $1 per day. That means Jack’s fellow servants would have had to work 300,000 days to earn that same amount of income — in other words, assuming 6 days of work per week, they would have had to work for almost 1,000 years to earn that much income. Jack appears, to his co-workers, to have earned that income almost in one fell swoop (though in reality, he spent months of his free time toiling away at the clock).

The 2018 Tariffs in Many Graphs

Did president Trump’s first term tariffs, enacted in 2018, increase manufacturing employment or even just manufacturing output? Let’s set the stage.

Manufacturing employment was at its peak in 1979 at 19.6 million. That number declined to 18m by the 1980s, 17.3m in the 1990s. By 2010, the statistics bottom out at 11.4m. Since then, there has been a rise and plateau to about 12.8m if we omit the pandemic.

Historically, economists weren’t too worried about the transition to services for a while. After all, despite falling employment in manufacturing, output continued to rise through 2007. But, after the financial crisis, output has been flat since 2014, again, if we omit the pandemic. Since manufacturing employment has since risen by 5% through 2025, that reflects falling productivity per worker. That’s not comforting to either economists or to people who want more things “Made in the USA”.

Looking at the graphs, there’s no long term bump from the 2018 tariffs in either employment or output. If you squint, then maybe you can argue that there was a year-long bump in both – but that’s really charitable. But let’s not commit the fallacy of composition. What about the categories of manufacturing? After all, the 2018 tariffs were targeted at solar panels, washing machines, and steel. Smaller or less exciting tariffs followed.

Breaking it down into the major manufacturing categories of durables, nondurables, and ‘other’ (which includes printed material and minimally processed wood products),  only durable manufacturing output briefly got a bump in 2018. But we can break it down further.

Why I Started Grading Attendance

I’ve taught college classes since 2010, but I never graded attendance directly until this year. I thought that students are adults who can make their own choices about where to spend their time, and if they could do well on my tests and assignments without spending much time in class, more power to them.

But I got tired of seeing students miss a lot of class, then fail by getting poor grades on the tests and assignments, or scramble for the last few weeks to avoid failing. Explaining the importance of attendance didn’t seem to help, so I finally turned to the economist’s solution- incentives. This Spring I tried grading attendance in one class, and this successful experiment plus the growth of AI mean I plan to grade attendance in all classes from now on.

The Benefits:

  • Get to know student’s names faster
  • Students feel rewarded for showing up
  • Students show up more, bringing more energy to the room
  • Students show up more, so they learn more and do better on other assignments
  • Physically showing up is one thing I can be sure the AI isn’t doing for them, it will be a while before humanoid robots are that good

The Costs That Turned Out Not to Be Big Deals

  • I thought students would dislike me policing their whereabouts and give me lower course evaluations (which is part of why I waited for tenure to try this). But my Spring evals were at least as high as usual, with none mentioning the attendance policy. When I asked students in a different class about this, most said they wished I would grade attendance if it meant less weight on exams.
  • I thought tracking attendance would be burdensome, but it turns out my main course software (Canvas) already has an attendance-tracking tool built in that lets you just click on names in a seating chart each day and enters grades automatically. It is certainly less burdensome than grading most assignments.

I still had some students disappear for a while due to personal issues; sometimes even the strongest grade incentives aren’t enough to get people to class. But overall I can’t believe I waited this long. I’m currently putting attendance as 10-15% of the course grade, but I dream about someday running a discussion-based class like a Liberty Fund seminar, doing a 100% attendance/participation grade, and not having to grade anything.
