Incentive Compatibility Review¶
Design review — instantiates Anticipatory Offset Governance
Reviews the design for the moves that pay targets more than compliance does, mapping each actor's incentive to offset and issuing patches that make the honest path the profitable one.
An Incentive Compatibility Review examines a planned intervention through one lens only: for each target, does complying pay better than gaming? Its defining move is not to enumerate every possible reaction (the red team does that) or to size it (the simulation does that), but to find the reactions that are profitable — the dodges a rational target is rewarded for taking — and then to redesign the incentive so those dodges stop paying. Its outputs are an incentive-lens actor map (who gains from which offset) and a set of alignment patches that flip the payoff ranking so the intended behavior becomes the one worth choosing. It fixes the offset at its root: the reason the target wanted to move in the first place.
Example¶
A payer introduces a financial penalty for hospitals with high 30-day readmission rates, meaning to reward better discharge planning. The review maps each hospital's incentives and finds that the cheapest way to lower the measured rate is not better care but relabeling: booking a returning patient as an "observation stay" rather than a readmission, or steering away the sickest patients most likely to bounce back. Both pay better than the intended behavior.
So the review issues patches: count observation stays and emergency revisits inside the metric so relabeling stops helping, and risk-adjust for patient severity so avoiding the sick stops paying. After the patches, the profitable move and the intended move point the same way — a hospital lowers its penalty mainly by actually reducing readmissions, because the cheaper dodges have been priced out. The review's product is that revised design, not a forecast of how many hospitals would have gamed it.
How it works¶
- Take the target's-eye view, actor by actor. For each anticipating actor, line up the payoff of complying against the payoff of the cheapest available dodge.
- Find where gaming dominates. Flag every place the dodge pays as well as or better than the intended behavior — those are the offsets that will actually happen.
- Patch the incentive, not the symptom. Change what is measured, risk-adjust, or add a counter-incentive so the honest path wins on payoff.
- Re-check for the next dodge. Each patch can open a new gap; iterate until the residual dodges are too small or too costly to bother with.
Tuning parameters¶
- Patch type — broaden the measure, risk-adjust it, or attach a counter-incentive. Each closes different dodges and carries different side effects.
- Alignment margin — how decisively compliance must out-pay gaming before the design is accepted; a thin margin invites relapse.
- Actor coverage — direct targets only, or intermediaries and gatekeepers who can also game the scheme.
- Iteration depth — how many rounds of dodge-and-patch to run before stopping.
- Simplicity vs completeness — elaborate patches close more gaps but add complexity that itself becomes gameable.
When it helps, and when it misleads¶
Its strength is that it removes the motive for offset rather than merely watching or measuring it — the only mechanism here that changes the incentive itself. Done well, it pre-empts the "hit the target, miss the point" failure, where a metric improves while the thing it was meant to capture does not.[n1]
Its failure modes are whack-a-mole and reach. Every patch adds complexity and can spawn a fresh dodge, so an over-patched scheme becomes a new gaming surface; and some behaviors simply cannot be cheaply re-priced. The classic misuse is a cursory pass that pronounces a design "incentive-compatible" to bless a decision already made. The discipline is to run the review adversarially against the red team's pathway inventory and to keep iterating until the profitable dodges are genuinely gone, not merely unmentioned.
How it implements the components¶
incentive_alignment_patch— the concrete design changes (re-measure, risk-adjust, counter-incentivize) that make the intended behavior the profitable one.anticipatory_actor_map— an incentive-focused map of the actors: not just who reacts, but who profits from reacting and through which dodge.
It works the incentive angle only. It does NOT compile the full response_pathway_inventory — that broader enumeration is Strategic Response Red Team, whose map this review re-reads through payoffs — and it does NOT size the residual offset, which is Pre-Implementation Response Simulation.

Editorial Notes¶
Form Classification¶
Form family: Assessment, Review & Assurance
Rationale: Incentive Compatibility Review operates as a bounded evaluation of existing evidence or work that produces a finding or disposition because it reviews the design for the moves that pay targets more than compliance does, mapping each actor's incentive to offset and issuing patches that make the honest path the profitable one
Independent corroboration: The frozen evidence defines Incentive Compatibility Review as 'Reviews the design for the moves that pay targets more than compliance does, mapping each actor's incentive to offset and issuing patches that make the honest path the profitable one', so its operative form is Assessment, Review & Assurance.
Review outcome: Independent reviewer agreement; high confidence.
Origin Attribution¶
Primary origin: Economics & Finance
Origin pattern: Single lineage
Present-day reach: Multi-domain
Rationale: Testing whether compliance is each actor's best response is the central criterion of economic mechanism design.
Related originating lineages:
- Operations Research — Game-theoretic optimization and adversarial policy analysis materially support systematic offset search.
- Organizational & Management Science — Actor maps and alignment patches operationalize the analysis in institutional design.
Review resolution: Both reviewers independently assign economics_finance as the primary originating domain, so that shared primary is retained. Alternate domains are the union of reviewer-identified formative or independently originating lineages; later application settings alone are excluded. The evidence describes one principal historical lineage. It has established independent use across several domains, but that does not make it domain-free. The encyclopedia entry makes that composition explicit.
Encyclopedia synthesis: The exact catalogued form synthesizes established practice rather than reproducing a single standard historical label.
Review outcome: Reconciled after independent review; high confidence.
Notes¶
A patch is a design change, so it is not free: closing one dodge can raise administrative complexity or shift the burden onto a different actor. When the profitable dodges only appear after launch, the fix moves from this pre-launch review to the Adaptive Recalibration Procedure, which re-patches the incentive mid-flight.
[n1] Goodhart's law — "when a measure becomes a target, it ceases to be a good measure" (after Charles Goodhart) — names the failure this review exists to forestall: targets optimize the metric rather than the outcome it stands for. Formally, an intervention is incentive-compatible when acting as intended is each participant's own best response. ↩
