Why no mirror

The paper’s named results establish strategy optimality, existence of a budget-balancing order, welfare properties, and equilibrium, but none states a computational complexity claim or algorithmic guarantee. Turning these strategic claims into a search or optimization problem would add a computational question the paper does not study. The proposed population limit also removes individual pivotality unless valuation classes act as coalitions, which changes the game.

fails bit a — no named computational result to mirror

What the mirror covers

No computational result is anchored; the strategic optimality, budget-balance, welfare, and equilibrium results remain unmirrored.

The case FOR (proponent)

I can’t make a compliant positive case anchored in this paper: it contains no named computational result asserting that a problem is in P, NP-hard, FPT, or similar.

Its theorems concern strategic properties instead: the strategy in Theorem \(\ref{thm:dom1}\) is optimal; Theorem \(\ref{thm:zero}\) says some player order achieves budget balance; Theorem \(\ref{thm:social}\) gives socially optimal strategies; and Theorem \(\ref{thm:nash}\) establishes Nash equilibrium and Pareto optimality claims. None classifies the complexity of a computational problem, so none can serve as an anchor under your criteria.

A large population divided into a few valuation classes is imaginable, with mass representing each class. But the paper’s sequential pivotal mechanism relies on individual players moving in an order and potentially affecting the project decision. In a nonatomic population, an individual has no pivotal effect; treating whole classes as players would change the strategic model. The paper’s continuous valuation domain \([0,c]\) is also continuity of types, not of the population.

So a population-continuous computational agenda could be devised, but it would not mirror a named computational result in this paper. The paper offers no eligible anchor for the requested case.

The case AGAINST (opponent, writing after the proponent)

The proponent has supplied no eligible anchor, and that is decisive here. The paper’s theorems establish properties of strategies, budget balance for some player order, social-welfare optimality, and Nash equilibrium. None states a computational complexity result. So there is no named computational finding to mirror; attaching a new search or optimization problem to one of those theorems would create a different research question, not continuize a computational result from this paper.

The best salvage would be to ask for an order that achieves budget balance, or for a welfare-maximizing strategy. But the paper proves an existence claim pointwise and gives explicit strategy rules; it does not study the complexity of finding an order or computing a strategy. To make either into a computational problem, one would have to specify a new input and output, including how a distribution of valuations induces an order and how strategies are represented.

There is also a substantive obstacle to that repair. These results exploit individual pivotality: a player’s report can change the project decision or other players’ pivotal taxes. In a nonatomic population, one individual has zero mass, so that report cannot change aggregate value or another agent’s counterfactual. The pivotal incentives underlying the sequential strategies disappear. A positive-mass valuation class acting as one strategic player could restore influence, but that makes the class a coalition; it changes the paper’s individual, sequential game rather than representing many interchangeable individuals.

This is a strong case against a *mirror of this paper’s results*, though not a proof that no newly designed continuous public-goods game could be worthwhile. Such a game may be interesting on its own; it would not supply the missing computational anchor here.

The adversarial triple: the proponent anchors on up to three named results; the opponent sees that case and must defeat every anchor; the judge decides which case convinced it. These are the pipeline’s own outputs, generated by tools/triple_run.py — no human edited them. The paper’s own text is not reproduced here beyond the quoted statement above.
