Why no mirror

Proposition 2 is the only plausible computational anchor: its proof explicitly constructs transfer amounts, so it has constructive computational character despite lacking a stated complexity bound. But in a nonatomic country population, one country’s departure has no aggregate effect; preserving the spillover that drives the proposition requires a coordinated bloc exit, a different decision problem that the proponent does not specify tightly enough to hand to a prover.

What the mirror covers

The proposed mass-exit idea concerns Proposition 2’s transfers; it does not cover Propositions 1 or 3–6, and no valid mirror survives.

The case FOR (proponent)

I can’t identify a qualifying anchor in this paper. Its numbered results are economic propositions about equilibrium and welfare, not computational results about a problem being in \(P\), NP-hard, FPT, or similar.

The closest near-miss is Proposition 2, proved in this paper: when a country wants to exit, a set of fiscal transfers that prevents its exit and is weakly preferred by every other member exists if and only if the exit is socially inefficient. That is a substantive existence result, but it does not analyze the computational complexity of finding the transfers. Propositions 1 and 3–6 likewise establish economic conditions about union formation, exit costs, credibility, and post-exit deals.

A continuum of many small member jurisdictions could be a sensible extension: types might encode preferences, trade technologies, and shock parameters; mass would represent the share of members of each type; and the model could study exit mass and transfers. But the paper’s results concern a finite set of countries and a shock to an individual country. That extension would be a new model, not a continuous mirror of a named computational result here. So, under the requested anchor rule, there is no honest continuous problem to hand to a prover for this paper.

The case AGAINST (opponent, writing after the proponent)

The strongest negative case is that there is no computational result here to continuize. Propositions 1–6 establish equilibrium and welfare claims: when unions form, when exits are efficient, whether transfers or exit costs help, and when post-exit deals benefit the parties. None states a complexity result or studies an algorithmic problem.

Proposition 2 is the closest candidate, but it proves an economic existence claim: voluntary transfers that prevent an exit exist exactly when that exit is socially inefficient. Its proof even constructs a transfer scheme from the members’ welfare changes. One could ask how to compute transfers in a new model, but that would add an algorithmic problem to the paper rather than mirror one it studies.

The best attempt at a continuous version would treat countries as a distribution of types and ask whether transfers can prevent an exiting mass from leaving. That changes the key event. A single country has an identity and its own market and exporting firm; in a nonatomic population it has zero mass, so its departure has no aggregate effect on the other members—the spillover that motivates Proposition 2 disappears. Give a type positive mass and the event becomes a bloc exit, with different effects on union policy and market access. Keep one country as a positive-mass atom and the model becomes a hybrid centered on a distinguished member. Each could support new economic analysis, but none is the continuous-population version of the proposition’s single-country exit.

A large cohort of similar jurisdictions in a voluntary standards union is a conceivable setting for that new work. That is the negative case’s weak point: the authors might recognize such an extension as relevant. But it still supplies no computational anchor in this paper. Making it a computational-social-choice project would require introducing computational questions and structure the paper does not contain.

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.
