“The Skateboarding Ethic and the Spirit of Anti-Capitalism.” That was the title of an unusual paper presented at the annual meeting of American economists this year. The title was clearly a reference to a famous 1905 book by German sociologist and economist Max Weber, The Protestant Work Ethic and the Spirit of Capitalism. And I really wanted to know what this economist was going to argue, and, even more, who he was.

This year’s economics conference was spread out across hotels around San Francisco’s Union Square. On the first day of the conference, it was raining hard, and I ran from my hotel to another one down the street to see this paper be presented.

Sopping wet, I entered a small, basement conference room before the presentations began. “Is this where the skateboarding paper is being presented?” I asked the room.

Sure enough, a Gen Xer with baggy blue jeans, Vans skate shoes, and a tweed blazer with elbow pads — the only fashion item that screamed “I’m an academic” — stood up and turned around. “Yes, I’m presenting the skateboarding paper here,” he said.

This tweed-jacketed, Vans-wearing man was Thomas Kemp. He’s an economist at The University of Wisconsin–Eau Claire. Kemp says he’s been skateboarding for 40 years, and he continues to skate every day he can (it gets harder to skate during Wisconsin’s winters, so Kemp says he snow skates as well).

For a long time, Kemp published pretty standard economic papers. Papers with titles like, “The Impact of Water Clarity on Home Prices in Northwestern Wisconsin” and “Estimation of product price elasticity of demand.”

“When I was a graduate student, I was actually going to write about skateboarding, but I was told ‘that’s not a good idea,’” Kemp says. But Kemp is more established now. In fact, he’s the chair of his economics department, so he’s more willing to ollie onto the topics he’s the most passionate about.

Kemp’s transformation began a few years back, when he discovered the burgeoning academic literature on skateboarding. “I was just blown away, like, ‘Wow, people are doing academic work on skateboarding,’” Kemp says. And that’s when he did his 180 kickflip.

“ I literally dropped everything else I was working on and started writing papers on skateboarding,” Kemp says.

The Value of Skateparks

Kemp has now published a series of economic papers about skateboarding. One paper, recently published in The Journal of Economic Analysis, is titled “Shred Central: Estimating the user benefits associated with large public skateparks.” Kemp estimated the consumer benefits of the Lauridsen Skatepark in Des Moines, Iowa. At 88,000 square feet, it’s the largest skatepark in the United States.

One of the issues with the economics of skateparks is they’re generally free to use, which makes it difficult to figure out how much they’re actually worth. This is a common problem for public goods, like parks, beaches, rec centers, and so on. Determining the value of a skatepark is important to figure out whether, for example, communities should build more skateparks, and how big and tricked-out those skateparks should be. Despite the popularity of the sport — estimates suggest there may be as many as 9 million skateboarders in the US — “public resources devoted to skateboarding lag far beyond other leisure activities such as softball, tennis, or soccer,” Kemp writes.

Kemp argues that the distance skaters (and BMXers, roller bladers, and other recreationists) are willing to travel to go to the skatepark provides a good way to estimate the value of it. Traveling requires time and money, so the distance users are willing to travel provides an indication of how much they think a skatepark is worth.

In “Shred Central,” Kemp surveyed skateboarders at Lauridsen Skatepark, and found they “will travel great distances at significant cost to ride a park of high perceived quality.” Crunching numbers on use of the park and travel distance, Kemp estimates that the user benefits of this skatepark are “$61 per user per day and roughly $488,000 annually.” This high estimate for the value of the skatepark suggests that there’s a shortage of high-quality skateparks around the country and that community leaders should build more of them.

“The Skateboarding Ethic and the Spirit of Anti-Capitalism”

In his 1905 book, The Protestant Work Ethic and the Spirit of Capitalism, Max Weber argued that Protestant Christianity, especially Calvinism, promoted ethics, like thrift and hard work, that helped nurture the birth of capitalism and rapid economic growth in Northern Europe.

Like Protestants, skateboarders, Kemp argues, have their own set of ethics that can affect their economic lives. And, in Kemp’s view, these ethics can come into conflict with capitalism. For example, skateboarders are known to skate on private property and in front of businesses in search of cool, skateable features. It’s one reason why community leaders have been building skateparks: to encourage skaters to skate in sanctioned areas that are less disruptive to business.

Kemp sees a similar process in history with stickball and baseball. During his presentation, Kemp showed a picture of baseball legend Willie Mays playing stickball in the street when he was young. Like with skateboarding, Kemp says, many leaders saw stickball as a nuisance that disrupted commerce. Kids would shut down streets and disrupt traffic to play the game. They would hit balls and dent cars and break windows. This “irritation to commerce,” Kemp suggests, inspired communities to start building baseball diamonds in community parks and institutionalize the game into more organized and less disruptive baseball leagues.

“The drive towards creating skateparks appears to me to be on a similar trajectory to what we saw with stickball into baseball,” he says. “That said, we’re now 50-plus years into skateboarding history, and so far, skateboarding seems to be relatively immune from that institutionalization. It’s just as common to see kids skateboarding out in the streets as it is in a skatepark, perhaps even more so.”

Kemp was the last person to present a paper during this particular conference session. The paper presented before him was much less fun, highlighting physical and mental health problems plaguing our society, including the rise of depression, anxiety, and deaths of despair. The author blamed our economic and health systems, which “prioritizes profits over people’s health,” for making these problems worse.

In important ways, skateboarding is a product of capitalism. For decades, for-profit companies have developed and manufactured better skate decks, trucks, and wheels. They’ve marketed the sport. They’ve popularized it. They’ve made it more accessible. Kemp acknowledges that. But he also sees ethics within the culture of skateboarding that can help people overcome the challenges they may face in our capitalist society.

The skateboarding ethic, Kemp says, is “an ethic of resiliency. I fall, I get up, I do it again.” It’s an ethic of “self-betterment. The skateboarder is always trying to do another trick. They’re trying to do the trick better with more style. They’re trying to do it in different places. They’re comparing themselves to their past selves and not necessarily other skateboarders.” And it’s an ethic that isn’t really concerned with competition with others. Skateboarding, he says, is a non-zero sum game. “In other words, if I do the trick, it doesn’t matter that the other skateboarder didn’t do the trick. I’m not in competition with them. I don’t win, they lose, or I lose, they win. No, we’re all winning — hopefully — compared to our previous selves.”

Skateboarding, Kemp suggests, can help us become more resilient. It can help us build more pride in ourselves. It can help us fight isolation and build community. And it can help us exercise, alleviate stress, find joy, and escape the 9-5 grind.

“Skateboarding has something to show us about living life in these challenging times that we find ourselves in,” Kemp says.

Kemp’s presentation, appropriately, took place in San Francisco, which is widely recognized as one of the best and most hardcore skateboarding cities in the world. Skaters here are known to “bomb” hills like daredevils, reaching high speeds and doing incredible tricks. And the city has really come to embrace skateboarding. For example, the San Francisco Museum of Modern Art currently has a skateboarding exhibit called “Unity Through Skateboarding” (which, apparently, my son and wife really enjoyed while I was attending this conference).

“San Francisco is legendary,” Kemp said. “Of course, this is a work trip. But, hopefully, I’ll get some skating in while I’m here.”

Satellite images show Iran school strike hit more buildings than earlier reported

Satellite images show Iran school strike hit more buildings than earlier reported

The bombing of an Iranian elementary school that killed some 165 people, many of them schoolgirls, included more targets near the school than has been initially reported, a review of commercial satellite imagery by NPR has found.

The images suggest that the school was hit on Saturday as part of a precision airstrike on a neighboring Iranian military complex — and that it may have been struck as a result of outdated targeting information.

The new images come from the company Planet and are of the city of Minab, located in southeastern Iran. They show that a health clinic and other buildings near the school were also struck. Three independent experts confirmed NPR’s analysis of the additional strike points.

The strike points “look like pretty clean detonation centroids,” said Corey Scher, a postdoctoral researcher at the Conflict Ecology laboratory at Oregon State University.

“These certainly appear like detonation sites,” agreed Scher’s colleague, Oregon State associate professor Jamon Van Den Hoek.

Jeffrey Lewis, a professor at Middlebury College who specializes in satellite imagery, said the imagery was consistent with a precision airstrike.

The images show “very precise targeting,” Lewis told NPR. “Almost all the buildings [in the compound] are hit.”

Iranian state media said 165 people died in the bombing, which struck a girls’ school. The school was located within less than 100 yards of the perimeter of an Iranian Revolutionary Guard naval base, according to satellite images and publicly available information. The clinic was also located within the base perimeter, although both facilities had been walled off from the base.

Israel has denied involvement. “We are not aware at the moment of any IDF operation in that area,” Israel Defense Forces spokesperson Nadav Shoshani told NPR on Monday. “I don’t know who’s responsible for the bombing.”

At a press conference Wednesday morning, U.S. Defense Secretary Pete Hegseth said that the U.S. is looking into what happened at the school. “All I know, all I can say, is that we’re investigating that,” Hegseth said. “We, of course, never target civilian targets.”

Given Minab’s location in the southeastern part of Iran, Lewis believes it’s more likely the U.S. would have conducted the strike than Israel. As one gets farther south and east in Iran, “a strike is much more likely to be a U.S. strike than an Israeli strike because of the type of munitions and the geographic location,” he said.

Esmail Baghaei, the spokesman for Iran’s Foreign Ministry, called the strike “deliberate” and said that the U.S. and Israel bombed the school in part to tie up Iranian forces in the region with rescue efforts. “To call the attack on the girls school merely a ‘war crime’ does not capture the sheer evil and depravity of such a crime,” he said.

But Lewis said it’s more likely that the strike was the result of an error. Satellite images show that the school and clinic buildings were both once part of the base. The school was separated from the base by a wall between 2013 and 2016. The clinic was walled off between 2022 and 2024.

Lewis believes it’s possible American military planners had not updated their target sets.

“There are thousands of targets across Iran, and so there will be teams in the United States and Israel that are responsible for tracking those targets and updating them,” he said. “It’s possible that the target didn’t get updated.”

The Pentagon did not immediately respond to NPR’s request for additional information about the strike.

NPR’s Arezou Rezvani and NPR’s RAD team contributed to this report.

Mojtaba Khamenei, son of former supreme leader, tipped to become Iran’s next head of state

Mojtaba Khamenei, son of former supreme leader, tipped to become Iran’s next head of state

Mojtaba Khamenei, the second son of the assassinated Ali Khamenei, is being heavily tipped to succeed his father as supreme leader of Iran, which would pitch a hardliner into the task of steering the Islamic republic through the most turbulent period in its 48-year history and offer a powerful signal that, for now, it has no intention of changing course.

No official confirmation has been given and the announcement may be delayed until after the funeral of Ali Khamenei, which was on Wednesday postponed.

His son is believed to have been the choice of the Islamic Revolutionary Guard Corps (IRGC), and the Israeli defence minister, Gideon Saar, has warned he will be assassinated.

Ayatollah Seyed Khatani, a member of the Assembly of Experts, the body that chooses the new supreme leader, said the assembly was close to selecting a leader.

Rigid in his anti-western views, Mojtaba Khamenei is not the candidate Donald Trump would have wanted. Marco Rubio, the US secretary of state, said on Tuesday that Iran was run by “religious fanatic lunatics” – and Khamenei’s appointment is hardly likely to dispel that opinion.

The choice of supreme leader is made by the 88-strong Assembly of Experts, who in this case are picking from a field of six possible candidates. His election would be a powerful if unsurprising symbol that the government is not looking to find an accommodation with America.

Trump has said the worst-case scenario would be if Khamenei’s successor was “as bad as the previous person”.

There has been speculation for more than a decade that he would be his father’s successor, which grew when Ebrahim Raisi, the elected president and favourite of Khamenei, was killed in a helicopter crash.

Mojtaba Khamenei was born in 1969 and studied theology after graduating from high school. At the age of 17, he went to serve in the Iran-Iraq war, but it was not until the late 1990s that he came to be recognised as a public figure in his own right.

After the landslide defeat of Khamenei’s preferred candidate, Ali Akbar Nategh Nuri, in the 1997 presidential election, where he won only 25% of the final vote, various conservative Iranian groups realised the need to make changes to their structures and Mojtaba Khamenei was central to that project.

He was also seen as instrumental by reformists in suppressing the protests in 2009 that came after allegations the presidential election had been rigged, with his name chanted in the streets as one of those responsible. Mostafa Tajzadeh, a senior member of Iran’s reformist parties who was imprisoned after the vote, alleged that his and his wife, Fakhr al-Sadat Mohtashamipour’s, legal case was under the direct supervision of Mojtaba Khamenei.

In 2022 he was given the title of ayatollah – essential to his promotion. By then he was a regular figure by his father’s side at political meetings, as well as playing an influential role in the Islamic Republic’s Broadcasting Corporation, the government’s official media outlet often criticised for churning out dull political propaganda that many Iranians reject in favour of overseas satellite channels. He has also played a central role in the administration of his father’s substantial financial empire.

His closest political allies are Ahmad Vahidi, the newly appointed IRGC commander; Hossein Taeb, a former head of the IRGC’s intelligence organisation; and Mohammad Bagher Ghalibaf, the current speaker of the parliament.

His rumoured appointment and its hereditary nature has long been resisted by reformists. The former prime minister Mir Hossein Mousavi, referring to the long history of rumours about Mojtaba Khamenei succeeding his father as leader, wrote in 2022: “News of this conspiracy have been heard for 13 years. If they are not truly pursuing it, why don’t they deny such an intention once and for all?”

The Assembly of Experts, in response, denounced “meaninglessness of doubts” and said the assembly would select only “the most qualified and the most suitable”.

Israel on Tuesday struck the building in the Iranian city of Qom, one of Shia Islam’s main seats of power, where the assembly was scheduled, but the building was empty, according to IRGC-affiliated media.

Senators Question Kristi Noem on ICE Immigration Tactics

Homeland Security Secretary Kristi Noem repeatedly refused to apologize for suggesting that Alex Pretti and Renee Good, two U.S. citizens shot and killed by agents, were domestic terrorists.

What we’ve seen is a disaster under your leadership, Ms. Noem. A disaster. What we’ve seen is innocent people getting detained that turn out are American citizens. I could talk about the culture that’s been created here. After the killings of Renee Good and Alex Pretti, when I spoke to Alex’s parents, they told me that you calling him a domestic terrorist — this was directly from them — the day after he was killed, a nurse in our V.A., Alex — one of the most hurtful things they could ever imagine was said by you about their son. Do you have anything you want to say to Alex Pretti’s parents? Ma’am, I did not call him a domestic terrorist. I said It appeared to be an incident of — I think the parents saw it for what it was. In a hearing — recent hearing before the HSGAC committee, C.B.P. and ICE officials testified under oath that their agencies did not inform you that Pretti was a domestic terrorist — during that hearing, stated during that hearing, I was getting reports from the ground, from agents at the scene, and I would say that it was a chaotic scene. How did you think that calling them domestic terrorists at that scene was somehow going to calm the situation? The fact that you can’t admit to a mistake, which looks like under investigation, it’s going to prove that Ms. Good and Mr. Pretti probably should not have been shot in the face and in the back. Law enforcement needs to learn from that. You don’t protect them by not looking after the facts.
