Why no mirror

Neither named theorem states an algorithm, complexity bound, or hardness result; each establishes an incentive property of a mechanism. Section 4 reports equilibrium simulations but gives no named computational guarantee. A continuous population of similar homes could motivate a follow-up, but it is not anchored in a qualifying result from this paper.

fails bit a — no named computational result to mirror

What the mirror covers

No named computational result qualifies as an anchor: Theorems 3.1 and 3.2 concern incentive properties, and Section 4 reports simulations without a formal computational guarantee.

The case FOR (proponent)

I can’t make a valid anchored case from this paper: it contains no named result about a problem being tractable, hard, or having a particular computational complexity. Theorem 3.1, proved here, says truthful reporting is a Nash equilibrium under uniform scoring. Theorem 3.2, also proved here, says truthful reporting is strictly dominant under the sum-of-others’-plus-max mechanism. Those are incentive-compatibility results, not computational-complexity results. Section 4 computes equilibrium effort choices experimentally, but states no named algorithmic or complexity result about that computation.

There is a plausible population regime: an aggregator serving many similar homes, grouped into types by their prior demand information, consumption model, and effort cost. One could ask how to compute equilibrium effort choices when each type occupies a given fraction of the population. But that would be a new computational question. The paper’s equilibrium experiments do not establish a named result to anchor it, and the fact that its demand estimates are Gaussian does not make its population continuous.

So the paper suggests a possible follow-up mirror, but it supplies no qualifying computational anchor for the requested case.

The case AGAINST (opponent, writing after the proponent)

The strongest case against a mirror is that the paper has no named computational result to mirror. Theorem 3.1 proves that truthful reporting is a Nash equilibrium under uniform scoring; Theorem 3.2 proves strict dominance under sum-of-others’-plus-max. Those are incentive-compatibility results, not complexity or algorithm results. Section 4 uses iterated best response to run experiments, but gives no formal result about the complexity of computing an equilibrium.

The best proposed extension is to model an aggregator’s many similar homes as a continuous population, with types capturing cost coefficients, prior information, and consumption models, then ask how to compute equilibrium effort choices from the type masses. That is a plausible new research question. But it changes the target: it is not a continuous version of either theorem. To make it an algorithmic problem, one would first have to specify the finite input encoding, the equilibrium concept and selection, and what output or approximation counts as a solution. The paper supplies none of these. The extension may be worthwhile, but it is not anchored in a computational result of this paper.

The Gaussian consumption beliefs do not fill that gap: they make uncertainty over outcomes continuous while the paper’s society still has \(N\) home agents. Nor does the paper’s simulation establish a continuous-population result.

This is a strong case against a *mirror of this paper’s results*, but it does not honestly establish the broader claim that no scenario could yield worthwhile ChoCo work. A large aggregator serving many similar homes is a credible high-multiplicity regime, and equilibrium computation there could be a useful follow-up. The negative case is strongest on the absence of a qualifying anchor; the universal claim goes beyond what the paper supports.

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.
