Does the AstroForge PGM system-dynamics model actually produce the 'price holds then collapses' shape, and under what assumptions?
claim-asteroid-pgm-price-holds-then-collapses rests entirely on the abstract of Nachtrieb & Smith (arXiv:2607.06806). The abstract asserts the hold-then-collapse trajectory, but the load-bearing content — whether the model actually generates that curve, and on what assumptions — was never examined.
Why it matters. The claim is a mechanism/prediction (deployment lag → held price → cliff). Its interest as a general pattern (any unlimited-reserve, capacity-constrained disruption) depends on the assumptions being non-degenerate: e.g. a single first-mover supplier, no anticipatory terrestrial price cuts, a fixed lower cost floor, demand elasticity, stockpiling behaviour. A model rigged to a monopoly delivery channel would produce the result trivially.
What would answer it.
- Read the paper body (arXiv:2607.06806), not just the abstract.
- Open the ancillary model file
AstroForge_v5.mdl(a Vensim-style system-dynamics model on the arXiv submission) and inspect the actual stocks, flows, and pricing rule. - Note whether the paper is peer-reviewed or remains a preprint, and flag the conflict of interest (paper co-motivated by the company it models).
- Compare against the classical counterpoint, Hotelling's rule for exhaustible-resource pricing, which the paper is implicitly arguing against.
Resolving this can lift the [unverified-mechanism] flag on claim-asteroid-pgm-price-holds-then-collapses.
