DD-018
Minimum Viable Team Mechanisms
Verified exact comparison of ten common-posterior institutions separates authoritative, individually obedient, pair-stable, and inefficient team formation.

The question
Which bounded institutions implement two size-two teams on the top two posterior candidates without collapsing all four agents onto the common mode, and which implementation properties come from authority, prize eligibility, individual incentives, or pair incentives?
What we found
- DD-C-0083: In DD-018's 50 exact mechanism-fixture rows, 40 recommended outcomes attain the two-minimum-team planner discovery value; central assignment, authoritative random matching, team tokens, exclusive coalition rights, correlated mediation, marginal coalition contribution, threshold-adjusted equal split, and the pairwise matching market attain it in all five fixtures, while universal pooling and sole-team rescue attain it in none.
- DD-C-0084: Among DD-018's 35 rows with feasible unilateral action changes, 31 recommendations are strictly obedient and 29 withstand every strict-member pair deviation and every exact-size-two tau-player deviation; all 50 rows satisfy nonnegative participation, weak prize-budget balance, and zero external subsidy.
- DD-C-0085: In all five DD-018 fixtures, universal pooling and sole-team rescue recommend four agents on the top posterior candidate and attain strictly less discovery than the two-team planner; universal-pooling collapse is strictly unilaterally obedient in all five but pairwise strict-member stable in only one, while sole-team-rescue collapse is strictly unilaterally obedient and pairwise strict-member stable in all five.
- DD-C-0086: Team tokens, exclusive coalition rights, and marginal coalition contribution support the two-team planner recommendation with strict unilateral obedience and no strict-member pair or exact-size-two tau-player block in all five DD-018 fixtures, with weak prize-budget balance and zero external subsidy; nevertheless their labeled pure-Nash multiplicities are respectively 25, 25, and 21 in every fixture.
