1. The trap, in plain English
You run a company in a competitive industry, say customer support or software development. An AI tool arrives that can do much of what your human employees do. The AI costs about $18,000 per role per year; a human costs $60,000, all-in. Every role you automate saves about $42,000.
You'd have to be sentimental or bad at math to leave that on the table. So you automate. Your competitors do too.
The workers you let go don't stop needing things; they stop buying things. Some of their spending went to your products, some to your competitors'. The income they would have circulated is mostly gone. Only a fraction returns via new jobs or unemployment insurance. Your cost-saving move just shrank the market you sell into.
But you're not alone. You share customers with N competitors. When you automate one role and destroy some demand, only 1/N of that damage lands on you. The rest spills onto your rivals. From any one firm's point of view, the cost savings look full-sized and the demand cost looks tiny. The same is true for every firm in the market.
Every firm reaches the same conclusion and automates. Collectively, demand falls further than any single firm would have chosen. Profits fall, worker incomes fall, and a chunk of value evaporates outright.
Everyone could see this coming. The paper's model is deliberately transparent; every firm knows exactly what's happening. Rationality and foresight don't help. Automation is a strictly dominant strategy: no matter what anyone else does, each firm is individually better off automating. So everyone does.
Show the math
N symmetric firms each choose an automation rate $\alpha_i \in [0,1]$. Saving per role automated is $s = w - c$. Demand lost per role automated is $\ell = \lambda(1-\eta)w$, where $\lambda$ is the share of worker income spent in the sector and $\eta$ is the share of displaced wages replaced elsewhere. A quadratic friction $\tfrac{k}{2}\alpha_i^2$ captures the increasing difficulty of integrating AI task-by-task.
The Nash equilibrium subtracts only the firm's own share (1/N) of the demand damage; the cooperative optimum subtracts all of it. Wedge is positive whenever N > 1 and ℓ > 0.
2. Watch the mechanism
Four cupcake bakeries in a large city compete for the same customers. Each employs 50 workers (bakers, decorators, retail staff), who are themselves among the city's cupcake buyers. A new wave of automation (order kiosks, mixing robots, AI customer service) can handle about 40% of those workers' tasks at roughly a third the cost. Every firm will decide to automate; the private math is obvious. Click Next to advance one quarter at a time, and watch the lower chart: it tracks the spending these 200 workers contribute to the sector. By the end, every firm is worse off than if they'd coordinated.

3. Play with the model — for a single industry
Drag the sliders to set up a single industry like the consumer-retail example in §2, then watch how the Nash equilibrium pulls every firm past what would be collectively optimal. Both workers and owners lose. Section 4 widens the lens to the whole US economy.
Parameters
More firms means each feels less of its own demand damage, which widens the trap.
All-in yearly cost of employing one human: salary, benefits, overhead.
AI replacement cost relative to a human doing the same work. At 30%, AI is about a third as expensive.
How costly the last tasks are to automate. Higher values make it harder to push automation all the way.
Of every dollar a worker earns, how much comes back as sales in this sector. Realistic ranges: a narrow industry ~5%, a mid-sized sector (retail, consumer software) ~15-25%, broad consumer services ~30%+. Economists call this the sectoral "marginal propensity to consume."
How much of a laid-off worker's wages is recovered via new jobs or transfers. The rest is gone from the economy.
A tax equal to the external cost an activity imposes. Carbon tax is the classic example; this is its equivalent for demand destruction. Each firm pays for the demand damage its automation causes to the other firms.

Outcomes: independent vs. coordinated decisions
4. The Bigger Picture
We've seen how the mechanism works inside a single industry, with four consumer-retail firms sharing a sector's demand. What happens when we widen the scope to the US economy as a whole?
Scenario inputs
Massenkoff & McCrory2 find roughly 30% of US workers have zero observed exposure (cooks, mechanics, lifeguards, dishwashers). The remaining 70% have some, with the top quartile averaging 39% task coverage. The 40% default is a midpoint for "workers in roles where the trap could bite."
Of an exposed worker's role, what fraction automation actually replaces when every firm decides independently. For reference, Massenkoff & McCrory2 put top-quartile observed coverage at 38.8% today; the most exposed individual occupations, like computer programmers, sit around 74%.
With foresight and coordination, how deep would automation go? Some is still productive; the cooperative level is lower than the race-to-the-bottom pace. The wedge between this and the independent path is the trap's cost.
How much of a laid-off worker's wages returns via new jobs, unemployment insurance, or other transfers.
Aggregate outcomes, per year
In historical context
Each historical bar is that downturn's peak real PCE drop (%) applied to today's ~$19T PCE base — a uniform sizing exercise, not a direct dollar comparison.
5. Emerging Trends
The evidence through early 2026 is mixed: aggregate employment data shows no statistically significant effect yet, while company-level layoff announcements increasingly cite AI as the reason.
Recent studies have not found a statistically significant link between unemployment and AI adoption. Massenkoff & McCrory's analysis2, using Current Population Survey data through mid-2025, finds no statistically significant increase in unemployment for highly AI-exposed workers since ChatGPT's release.
A Federal Reserve working paper from March 2026 looks at the occupation level. Crane & Soto (FEDS 2026-018)3 link O*NET skill data to the CPS and find that annual coder employment growth is about 3 percentage points lower post-ChatGPT than before. They also ask what coder employment would have done if it had simply tracked the industries where coders happen to work — and the actual slowdown is larger than that, which points to an occupation-specific shock rather than the broader tech pullback. Coder employment is still growing; it is growing more slowly. The authors flag that this is consistent with AI pressure but does not on its own prove it.
Challenger, Gray & Christmas data suggest a trend might be emerging: 54,836 AI-cited layoffs across 2025 (about 5% of total US job cuts that year)7 and another 27,645 in Q1 2026; in March alone, AI led all reasons for US layoffs, ahead of closings, restructuring, and market conditions.6
