AI and the Shrinking Firm

noreply@blogger.com (Michael Ward) — Tue, 09 Jun 2026 16:00:47 +0000

The way that Artificial intelligence (AI) is changing worker productivity may also be changing the optimal scale of the firm itself. According to a recent Axios report, AI-powered tools are enabling entrepreneurs to launch and operate businesses with little or no staff. Tasks that once required specialists in coding, graphic design, marketing, customer support, and bookkeeping can increasingly be performed by a single entrepreneur assisted by AI. The result is a growing number of "one-person firms" capable of generating revenue levels that previously required a small team. This contrasts with the trend since the industrial revolution in which ever more mechanization generated ever greater economies of scale and ever larger enterprises.

Some aspects of AI fit nicely into theories of the firm.

Transactions costs can be reduced by engaging with AI rather than an employee.
AIs eliminate employee principal/agent issues.
However, a more personalized AI may represent a relationship-specific sunk cost that can lead to holdup.

Has the risk premium for owning stocks disappeared?

noreply@blogger.com (Luke Froeb) — Thu, 04 Jun 2026 12:57:39 +0000

Axios reported that the equity risk premium (ERP) — the extra return investors expect for holding risky stocks instead of safe Treasuries — has shrunk to almost nothing. A safe 10-year Treasury bond pays about 4.5%. Stocks, measured against the companies' current earnings, return only about 3.7%. So right now the safe bond actually pays more than risky stocks, even though stocks have historically paid 3–5% extra. It looks as if you'd be taking on the risk without the usual reward.

HOWEVER: That 3.7% is based on what companies earn today. Stock prices are high because investors expect much bigger earnings in the future, driven by AI. If those bigger earnings actually arrive, then the price you pay today is reasonable, and stocks aren't really overpriced after all.

BOTTOM LINE: The risk premium you calculate depends on which earnings you use — today's or the future's. The historical rule assumes today's earnings are a good guide to the future. If AI changes how much companies earn, that assumption breaks, and the real risk premium is unknowable until we see whether the growth shows up.

Did incapacitation, deterrence, or rehabilitation reduce crime in Baltimore?

noreply@blogger.com (Luke Froeb) — Sat, 30 May 2026 18:15:06 +0000

The Free Press:

Bates, ``a new tough-on-crime prosecutor, ... replaced a scandal-plagued `progressive.'” ''

Incapacitation (selection): sometimes referred to as ``specific deterrence.''

Bates said that his office has identified about about 6,000 frequent, violent offenders and put between 3,000 and 3,500 of them in prison. The cooperation of federal law enforcement has helped take a number of these offenders off the streets.

Deterrence (incentives):

...more willingness to process felons in possession of a gun, and a more credible threat of punishment.

Rehabilitation:

“If you’re seeing your friends all going to prison, you’re going to go: ‘What? I don’t want to go to prison,’ ” Bates said. “Now all of a sudden, that job or that program someone’s offered you before that you didn’t want to talk about—now it looks pretty appealing.”

Wheelchair Fraud

noreply@blogger.com (Luke Froeb) — Sat, 30 May 2026 14:30:48 +0000

WSJ: They Get Wheeled on Flights and Miraculously Walk Off. Praise ‘Jetway Jesus.’

One viral account had 30 travelers needing wheelchairs to board a Southwest flight — and all but two walking off on their own at arrival. Another traveler, Carlos Gomez, described a flight delayed by 25 wheelchair passengers and said he sees more "wheelchair fraud" every trip. A flight attendant reportedly told him many able-bodied passengers request wheelchairs for "the VIP experience" — skipping lines, first crack at overhead bins — and that the "healing begins" once they learn they'd have to wait for assistance to get off.

More Test-Taking Accommodations in Wealthy Areas

noreply@blogger.com (Luke Froeb) — Sat, 30 May 2026 14:08:09 +0000

WSJ:

The share of SAT takers getting extra time has increased from 2% to 6.7% in the last decade; on the ACT, it rose from 4.1% to 7%. Qualifying students typically receive 50% more time — and on longer accommodations, up to double the standard limit. The surge is concentrated in wealthy areas, where federal data show that students at affluent schools receive accommodations at more than twice the rate of those at high-poverty schools.

Why? The payoff is huge (a few points can swing an admission), colleges aren't told who got extra time, and the qualifying bar is easy to clear — a diagnosis you can pay a neuropsychologist thousands to obtain. Same incentive for everyone; different ability to act on it.

(Lack of) Economies of Scale in Home Building

noreply@blogger.com (Michael Ward) — Fri, 29 May 2026 21:01:35 +0000

Brian Potter at Construction Physics takes a deep dive into economies of scale in construction. There are enough homes being built to observe economies of scale ... if they existed. But even manufactured homes don't seem to exhibit economies of scale. He marshals a lot of evidence to document where costs are incurred and how these compare to other industries. The lack of scale economies imply that the industry is rather unconcentrated. There are thousands of home builders with the five largest nationally having less than 25% of the market.

He concludes by trying to answer why there appears to be almost no economies of scale. One answer seems to be that that materials and labor home building costs represent 97% of costs with equipment costs being only 3%. Auto manufacturing, in contrast, is extremely capital intensive and hence firms are large. Home construction Fixed Costs (FC) are just not big enough for declining Average Fixed Costs (AFC) with scale to be too important. In contrast, high rise construction might require high cost excavators, cranes, pavers, pile drivers, etc. driving up the equipment cost share. Consequently, the five largest contractors for these projects have closer to 45% market share. The cost structure determines the market structure.

Is Business More Charitable than Charity?

noreply@blogger.com (Michael Ward) — Wed, 27 May 2026 18:46:40 +0000

“If I do my job right, the value to society and civilization from my for-profit companies will be much, much larger than the good that I do with my charitable giving.” - Jeff Bezos

A new opinion piece in the WSJ by Marian L. Tupy tries to calculate the value of the time saved by Amazon customers. I may quibble with some of his assumptions, but his point is that the cumulative value of the amount of time saved by Amazon customers likely exceeds the size of Bezos's fortune. This is on top of savings from lower prices and better product matching from a greater selection. Nordhaus famously estimated that entrepreneurs appropriate only 2.2% of the value of technological advances. Or Bezos likely got just a sliver of the pie that was created. Nordhaus's estimate could be off by a factor of forty and value appropriation by entrepreneurs would still be less than 100%. The amount of consumer surplus enjoyed typically rises when profit is earned. No one needs to get poorer just because someone else got richer.

I am reminded by a video clip of John Stossel interviewing Ted Turner from 1998 (I am that old). Ted Turner made his fortune creating a media conglomerate but had recently announced he would be giving away $1 billion in charity. Stossel's video makes the point that Turner could "do more good" by investing the $1 billion than giving it away. Charity divides the pie, investment grows the pie.

Selling Mattresses on Memorial Day

noreply@blogger.com (Michael Ward) — Mon, 25 May 2026 13:07:14 +0000

A nagging thought kept creeping into my more somber thoughts this Memorial Day. Why did retailers turn a day of remembrance into an opportunity to sell large consumer goods?

Wikipedia provide a nice history of the holiday but a short piece by McNutt & Partners explains some retailing aspects. For generations after the Civil War, it was called "Decoration Day" during which acknowledgement for the sacrifices of the dead were paired with commemorations meant to instill pride for country. It was renamed "Memorial Day" after WWII but a more significant change occurred in 1971 when it was moved from May 30 to create a three-day weekend. This made possible quick vacations and more time to consider large irregular purchases.

In economic terms, it concentrated demand for mattresses, and similar big-ticket items, into a single weekend (and then two weeks around the date). This is efficient if there are economies of scale so that retail costs fall with sales volume. This may also permit some price discrimination as those who are more demand elastic seek out these deals and schmucks like me pay higher prices the rest of the year.

Biggas Savings

Fabulous post on central planning from MarginalRevolution

noreply@blogger.com (Luke Froeb) — Sat, 16 May 2026 15:34:20 +0000

If our textbook gets to an eight edition, this will make it into Chapter 1.

MarginalRevolution on Central Planning:

The dilemma is this. There is a problem of information. Supercomputers will in fact help process information better. But if the information coming in is junk, and if that junk is built into the system because of the incentives that operators have in workplaces to lie, you will not have a planning system that can be put on its feet through the advent of computers or artificial intelligence or anything like that. I don’t see any reason to think that that strategic misalignment of incentives is simply there because of Russian backwardness or poverty.

..the burden of proof is on us, ~~on the Left,~~ if we want to continue with this slogan of replacing the market with the plan. The burden of proof is on us to show that it can work. You might say that along with this ought to come a kind of humility about facts and about the world. ... it would be criminally negligent to ignore the experience of decades upon decades of planning and say to yourself, “Well, that wasn’t what my vision of socialism is, so I’m going to ignore it.” Because if you do that, I can guarantee 100 percent you will end up repeating many of the mistakes and falling into the same dilemmas that the planners did.

FDA screens out studies with selection bias

noreply@blogger.com (Luke Froeb) — Mon, 11 May 2026 19:02:14 +0000

The Free Press:

..one of the studies looked at a group of people for six weeks—three weeks after they were vaccinated, and then another three weeks after that. If they were healthy after the second three-week period, the researchers concluded that it meant the vaccine was safe. In addition to the absurdly short length of time—six weeks to conclude the vaccine is safe?—it has an obvious and inherent bias toward healthy people, who are the most likely to get vaccinated.

Another study used an approach called “test negative”: It looked at people who came to the hospital with flu-like symptoms, some of whom had Covid and some of whom didn’t. If the group who were vaccinated had fewer people with Covid, it was supposed to mean that the vaccine worked. But in reality, it could simply mean that people who are vaccinated are more likely to show up at the hospital.

Waning Credit Card Market Power?

noreply@blogger.com (Michael Ward) — Mon, 11 May 2026 16:44:00 +0000

Historically, Visa and Mastercard earned substantial interchange fees because merchants had few practical alternatives. But FedNow, RTP, “pay-by-bank” systems, and blockchain-based settlement reduce switching costs and create new competitive options for merchants and fintech firms. Recent reporting from American Banker noted that RTP and FedNow transaction volumes are growing rapidly while firms simultaneously experiment with stablecoin-based international transfers that bypass traditional correspondent banking systems. Meanwhile, regulators are increasingly scrutinizing the market power of incumbent payment firms, including a new UK competition probe involving Visa, Mastercard, and PayPal. Network effects can create durable market power, but interoperability, regulatory pressure, and technological innovation can gradually transform even seemingly entrenched monopolies into far more competitive markets.

For decades, Visa and Mastercard benefited from one of the strongest forms of market power: network effects. Consumers tend to apply for cards that are accepted by more retailers and retailers accept cards that are held by more consumers. The resulting feedback loop favored first-mover credit cards and made subsequent entry difficult. But now new payment “rails” are beginning to erode that dominance. Real-time payment systems like FedNow and RTP now allow money to move directly between bank accounts in seconds, bypassing traditional credit card networks entirely. At the same time, stablecoins and open-banking systems are creating alternative methods for transferring funds with lower fees and faster settlement. Reuters recently reported that Visa’s annualized stablecoin settlement volume has already reached roughly $7 billion, while Mastercard is spending up to $1.8 billion to acquire stablecoin infrastructure firm BVNK. These investments reveal that incumbents increasingly view new payment rails as potential substitutes for traditional card networks.

A Hiccup in a Price War

noreply@blogger.com (Michael Ward) — Thu, 07 May 2026 17:57:00 +0000

Many antitrust economists are wary of the efficacy of predatory pricing, the strategy of pricing below costs to drive a competitor out of a market. The usual counter-argument is that, for it to work, the inevitable losses this will entail must be recouped after the rival has exited. Recoupment requires higher prices ... that can attract rivals again. Additionally, there are many tactics the prey can implement during the predation phase to try to thwart the predator.

A new one to me is giving away booze. As described in an article for Southwest Airlines 50th anniversary, Southwest pioneered frequent, cheap flights within Texas in the 1970s. In 1973, Braniff and Texas International started a price war offering $13 tickets. This was below Southwest's costs and was intended to drive Southwest out. Southwest countered with two-tiered prices. They would match the $13 price but also offer a $26 price that included a fifth of liquor. Most of its customers were business travelers who would expense the $26 ticket and keep the liquor. Since the liquor cost Southwest less the the the difference in the prices, it made more on the $26 tickets. Few of its customers opted for the money losing $13 tier. And, of course, the publicity of "free booze" was priceless.

Demand for Metro Rides to FIFA Matches is Inelastic

noreply@blogger.com (Michael Ward) — Mon, 04 May 2026 22:28:00 +0000

A recent Forbes article helps explain why getting to FIFA World Cup matches by will cost spectators $150 just for the metro train ride to get to the stadium. One contributing factor is that demand becomes more inelastic when it is a complement. Fans who have already committed to travel, lodging, and match tickets may have already budgeted $5,000 for the event. What’s another $150? The World Cup in NYC is a once-in-a-lifetime event for many attendees, and transportation costs are a small share of total trip expenditures. Combine that with few viable substitutes ways to reach the stadium and you have a market where consumers are effectively “captive.” Under these conditions, even large price increases result in only modest reductions in quantity demanded, allowing providers to charge prices far above normal levels.

From a pricing perspective, mega-events shift firms toward the region where optimal markups are high because elasticity is low. The inverse elasticity rule implies that when consumers are less price responsive, firms (or cost-recovering public agencies like NJ Transit) can pass through more of their costs without losing much demand. The $150 fare is therefore less an aberration than a predictable outcome of event-driven economics. The broader lesson is that mega-events elevate willingness to pay for complements, making demand more inelastic.

Vertical Integration and Screening

noreply@blogger.com (Michael Ward) — Wed, 29 Apr 2026 18:36:00 +0000

Cutler et al have published a new paper that adds to the catalog of reasons why firms might vertically integrate. They examine Skilled Nursing Facilities (SNFs) owned by hospitals. SNFs make referrals to hospitals for their residents who develop medical issues. But some referrals are more lucrative than others. The SNF has private information about which referrals will earn the hospital more profit. An unaffiliated SNF will capture none of this, but a vertically integrated SNF/hospital can profit by screening in the more lucrative patients and screening out the less lucrative patients.

Algorithmic Pricing Paper by some middling economist

noreply@blogger.com (Luke Froeb) — Wed, 29 Apr 2026 17:37:36 +0000

Froeb, Luke M. and Tschantz, Steven T. and Sokol, D. Daniel, Algorithmic Pricing When Capacity Turns Over: Competition, Collusion, and Information Sharing (April 29, 2026). Available at SSRN: https://ssrn.com/abstract=6675958

BOTTOM LINE:

First, sharing occupancy information intensifies competition, as firms compete in each realized state rather than on average. Second, as occupancy rises, it becomes more difficult to absorb diverted rival demand, so firms become worse substitutes for each other, shrinking the gains to collusion. Third, scale pools demand risk, raising occupancy and lowering prices.

Together, these findings identify a structural channel through which algorithmic pricing in capacity-constrained markets generates efficiency gains rather than collusive overcharges. ... The results yield practical guidance on which pricing algorithm to adopt and what information to feed it.

GLP-1 and Wedding Dress Uncertainty

noreply@blogger.com (Michael Ward) — Mon, 27 Apr 2026 23:00:00 +0000

Many a bride has chosen a dress a bit too small in anticipation of losing a few pounds before the big day. Sometimes they miss their goals. Bridal studios have long anticipated and planned for this. But with GLP-1 weigh loss medications, the dieting goals have become more ambitious. Even when the weight goals are met, the changes in body shape may not be what was anticipated. An ill-fitting dress, and unhappy bride, is even more likely. There is more uncertainty in the bridal dress business.

As the WSJ reports,bridal studios are trying to accommodate. They are handling more rush orders due to selections made later after gauging weight loss progress, holding more inventories of near-miss sizes and late dress change options, and trying to fit in more last minute alteration requests. All of these adjustments to accommodate the additional uncertainty imply additional costs. As if wedding planning wasn't anxiety inducing enough.

Europe's super power is regulation

noreply@blogger.com (Luke Froeb) — Thu, 23 Apr 2026 22:02:39 +0000

Economist: How Europe regulated itself into American vassalage:

Decades of over-regulating the old continent’s economy left businesses there unable to compete with American firms, which went on to trounce European ones even in their own backyards. ...

The annoying thing is that, taken individually, each piece of euro-regulation is laudable. Yes, Europe should aim for “net zero” carbon emissions by 2050. Of course regulating AI is sensible, lest the robots turn on us one day. Firm antitrust rules enforced by the EU have served consumers well, and so on. But taken together the effect has been a tangle of red tape that has left Europe awkwardly exposed. Efforts are afoot to get to grips with some of the more unappealing dependencies; next month the commission will unveil a “tech sovereignty package”. But it remains to be seen whether Europe can escape its role as a superpower in rule-making, yet a supplicant in everything else that matters.

Addessing Double Markups with the Zollverein

noreply@blogger.com (Michael Ward) — Wed, 22 Apr 2026 16:04:00 +0000

A new paper by Huning and Wolf explore how the Zollverein was formed. A point it makes is that this episode serves as one of history's most dramatic examples of solving the "double markup" trap. Before this 1834 customs union, the German lands were fragmented into hundreds of tiny states, each acting as a local monopoly over its stretch of road or river. As goods moved across borders, every state added its own high transit toll, essentially a successive markup on the wholesale cost. Just as a manufacturer and retailer both adding high margins can kill consumer demand, these "stacked" tolls inflated prices so severely depressed the volume of trade, leaving both the merchants and the states’ treasuries worse off than if they had coordinated.

The formation of the Zollverein effectively acted as a massive vertical integration project for the German speaking peoples. Internal customs barriers were abolished and replaced with a single, uniform external tariff with each state getting a share of the revenue based on its population. This eliminated the destructive cycle of successive markups, reduced final prices, and spurred a surge in cross-border trade. When independent entities in a supply chain (or a geography) stop competing for individual margins and start optimizing for the whole, the resulting efficiency gains can build an empire.

Is Tax Treament of Cannabis Punative?

noreply@blogger.com (Michael Ward) — Mon, 20 Apr 2026 21:29:00 +0000

I am posting about marijuana in honor of 4/20 day.

Marijuana has been decriminalized across many states but is still a as a federal controlled substance as an illegal Schedule I drug. As such, cannabis related firms are subject to section 280E of the tax code. As the Cannabis Business Times (CBT) reports:

... state-licensed cannabis operators are not permitted to make common or ordinary deductions on their federal tax returns. These deductions may include labor, legal fees, marketing, security or banking. With fewer deductions, cannabis operators, particularly those in retail, have an effective tax rate that at times can approach 70% or more.

This tax treatment was originally intended to be punitive and serve as a disincentive to conduct illicit drug-related business. CBT recommends rescheduling cannabis to Schedule III, so that firms would no longer be subject to 280E taxation. Reducing a 70% higher tax wedge would likely reduce prices and increase the quantity demanded. While decriminalized, federal tax treatment depresses demand.

Substitutability Determines Elasticity

noreply@blogger.com (Michael Ward) — Fri, 17 Apr 2026 13:47:00 +0000

The WSJ recently reported on how the Iran war is disrupting energy markets, particularly in Asia and specifically for Liquefied Natural Gas (LNG).

Qatar suspended production even before Iran struck its giant Ras Laffan export facility, causing damage that will take years to repair and delaying its expansion plans. The lost supply is ripping through the global economy.

One ripple has been a doubling in prices in Japan and Korea.

These high prices have led many Asian customers to substitute toward alternatives, including clean renewables but also dirty coal. What was not a viable substitute at $11/BTU has become viable at $22/BTU. Inelastic LNG demand has become more elastic as a result, suggesting that prices may have plateaued at $22/BTU.

The alternatives to agreement determine the terms of agreement: Iran's alternatives are bad and getting worse.

noreply@blogger.com (Luke Froeb) — Thu, 16 Apr 2026 15:30:00 +0000

WSJ:

“Iran insiders are rumbling about the looming economic catastrophe if Washington does not grant sanctions relief that would unlock prospects for economic recovery,” said Burcu Ozcelik, senior research fellow with the London-based Royal United Services Institute think tank. “Without the prospect of economic recovery, regime survival beyond the short term will face sustained structural and popular pressure.”...

“The attacks are not random,” said Kevan Harris, an authority on Iranian economic development and society at the University of California, Los Angeles. “They are targeting parts of the economy that are outward facing, that are bringing in foreign exchange which could be redistributed and directed at basic needs.” ...

Iranian oil that can’t be exported will fill the country’s storage tanks in two to three weeks, which would force the country to shut-in its oil production, data provider Vortexa said. Shut-ins in turn can damage fields and reduce their future output, analysts said. ...

Complicating Iran’s recovery is a host of economic and social ills that predate the recent war, including a worsening banking crisis. Pressure from international sanctions and economic mismanagement pushed Iran last year into an economic unraveling and drove hundreds of thousands of protesters into the streets.

The government’s own internet blackout—now at six weeks and counting—is contributing to the economic damage. Businesses rely on it to communicate with overseas customers and to complete orders, and a tech sector employs tens of thousands of Iranians.

UPDATE from The Free Press

So now is the time to think big. This would entail making three basic demands of Iran’s regime: release political prisoners, end the execution of protesters, and turn the internet back on. In exchange, the U.S. can offer to lift sanctions and unfreeze assets the regime needs just to pay the salaries of government employees.

“The president has real leverage to call not for just a halt in executions, but to seek the termination of the death penalty for certain ‘offenses’ in Iran,” said Behnam Ben Taleblu, a research fellow at the Foundation for Defense of Democracies. He added that a precondition for the next round of talks should be to restore internet access for Iranians, which has been cut off now for nearly two months. In addition, Ben Taleblu said, Trump should demand the release of political prisoners arrested after the June 2025 war and more recently after the national uprisings and state-led massacres in January. He estimates 21,000 Iranians were arrested in June, and that more than 50,000 have been arrested since January.

WH Smith Divisional Incentives

noreply@blogger.com (Michael Ward) — Tue, 14 Apr 2026 15:44:00 +0000

High powered incentives appear to have backfired for WHSmith. In its North American travel retail division, performance evaluation and rewards were tied to aggressive profit targets. These appear to have encouraged managers to recognize income early, particularly from supplier rebates. On paper, the division looked like a strong performer. In reality, profits had been pulled forward, inflating results by tens of millions of pounds. When compensation is tightly linked to a single, measurable outcome like short-term profit, employees rationally focus on maximizing that metric, even if doing so decreases overall profitability.

Managers did not commit outright fraud but made possibly defensible accounting choices. While headquarters wants sustainable profitability, accurate reporting, and long-term relationships with suppliers, division managers are rewarded based on short-term profitability. The result is a predictable reallocation of profitability to where it will enhance compensation. This is a reminder that the problem is not just bad actors, it is often good agents responding optimally to poorly designed incentives.
