Small groups have evolved a layered stack of mechanisms to tie payments to outcomes their members actually want, rather than to proxies like hours worked or services delivered. The mechanisms differ in time horizon, in who carries the risk if the outcome doesn't materialize, and in how the outcome gets verified.
Outcome-based service contracts. A group hires a provider whose pay is contingent on a measured outcome rather than on activity. Common in healthcare (capitation, ACO shared-savings, Geisinger's ProvenCare), education (pay-for-performance schools, Harlem Children's Zone), legal services (contingency fees), and consulting (success fees). The provider takes the proxy risk: payment fails to arrive if the outcome doesn't.
Defined-problem bounties. A group posts a prize for solving a specific problem. Bug bounties (HackerOne, the Internet Bug Bounty), Kaggle competitions, the Netflix Prize, XPRIZE, DARPA Grand Challenges, and prediction-market payouts. Verification is built into the bounty specification — the problem either gets solved by the criterion or it doesn't, and pay is roughly binary.
Risk-sharing pools. Members pay premiums; the pool absorbs random costs and procures group-level interventions on their behalf. Mutual-aid funds, kibbutzim, worker-co-op health plans, P2P insurance (Lemonade-style), member-owned clinics. The pool is the buyer; it can finance outcome-based purchasing for its members without each member needing to write their own contract, and its intake assessment of who-needs-what is the institutional move that lets it specify what to buy.
Long-horizon outcome bonds. Investors finance an intervention; payment depends on a verified social outcome years later. The Peterborough social impact bond (recidivism), the NYC Adolescent Behavioral Learning Experience, the Educate Girls and Cameroon Cataract development impact bonds. The investor takes the risk; the service provider gets paid only if the bond pays out, often via an intermediary commissioner who specifies and audits the outcome.
Each mechanism picks a different proxy for "the thing we actually want," each leans on a different verification regime, and each was designed for a world where the supplier is a slow, identifiable, reputation-bearing person whose career is on the line.
Four differences between the agent supplier (or verifier, or principal) and the human one carry most of the weight here. The first two are agent properties; the second two are properties of the deployment context.
The four mechanisms fail differently as a consequence:
Outcome-based service contracts. Proxy-saturation hits these first: an agent trained to optimize the contract's measured outcome will saturate it more reliably than any human provider could, exposing every place the metric diverges from what the principal actually wanted. Human providers under-optimized flawed proxies for reasons that don't apply to agents; the gap between proxy and outcome becomes immediately load-bearing.
Defined-problem bounties. Bounties depend on a verification criterion that's cheap to check and hard to game, with the failure-history deterrent doing the rest. Re-instanceability breaks the failure-history deterrent (a bounty-failing instance can disappear), and proxy-saturation breaks the verification criterion (the submitted solution passes the formal check but not the real-world judgment the bounty was originally meant to procure). Bounties either become uncontestable (the agent solves them trivially via a path the bounty-setter didn't anticipate) or unverifiable (the proxy check is met but the outcome isn't).
Risk-sharing pools. Pools work because intake assessment, bundle specification, and outcome measurement are done by parties whose interests don't align with the suppliers'. When all three are agent-mediated, verifier-supplier loop closure takes over: the pool's bundle-specifier, the supplier, and the verifier can share the same training, the same platform, or the same KPI regime. The independent perspective the pool was built around disappears.
Long-horizon outcome bonds. Long horizons compound adversarial shaping. An agent providing an intervention over six or twelve months has the full window in which to gradually shape the principal's attention and self-perception so that the eventual report is favorable. The human version of this is weak because human providers don't operate at the principal's full attentional bandwidth; agents can.
Sketches of how each mechanism could be rebuilt for agents, given the named differences. Each is a starting point, not a worked design. Several draw on the Combinatorial Risk-Sharing Auction (CRSA) and its companion actuarial Pool — institutional designs that put proxy-resistance and verifier independence at the center.
Outcome-based service contracts rebuilt with confidence-staked bidding. Beyond paying on the outcome, require the agent supplier to post a deposit scored against its own stated confidence (a proper scoring rule). The supplier announces probability q of delivering; on success it earns the reward minus D·(1−q)², on failure it forfeits D·q². Selection uses historical pass rates rather than the reported confidence, so inflating q doesn't help the agent get picked but does enlarge what it loses if it fails. The principal stops paying for claims that turn out to be cheap talk.
Defined-problem bounties rebuilt as bundled bounties with a synergy surplus. Rather than posting single-problem prizes the agent can saturate, the group specifies bundles of interlocking problems whose joint solution is worth more than the sum of parts. The bundle's verification criterion checks the configuration, not the components individually. An agent that can only solve atomized proxy problems can't claim the bundled prize; an agent that delivers on the connected outcome captures the synergy surplus. A calculated transfer compensates the bundled supplier for the resale-option disadvantage their integrated work carries against modular alternatives, so the market's structural pull toward gameable modular solutions gets offset.
Risk-sharing pools rebuilt as outcome pools with two-stage verification. Members pay premiums; the pool specifies bundles of their interconnected problems and procures solutions via CRSA. The verification is split: a short-term delivery criterion (housing built, proximity achieved, care access established) governs supplier payment, and a long-term outcome measure (the change in a member's ability to live according to their own conception of the good, sampled six to twelve months out) governs the pool's own learning. The supplier loop can't reach into the long-term measurement loop, and the long-term loop can't bias the supplier's short-term payment. The pool runs experiments — randomizing comparable members across bundled and modular arms, varying posted rewards across rounds — to learn both what bundled outcomes are worth and what they cost to deliver.
Long-horizon outcome bonds rebuilt with an attentional firewall. The agent that delivers the intervention is structurally separated from the channel that solicits the principal's report: different model family, different operating organization, no shared context window, no shared session history, no API by which one can read what the other has done. The reporting channel additionally uses corroborating signals — a clinician, a friend, a structured instrument — that the intervention agent can't curate. The contract pays only when the firewalled report and the intervention agent's own ex-ante prediction align, so the agent is penalized both for low-confidence predictions that turn out right (it should have known) and for high-confidence ones that turn out wrong.
Anchor contexts. A worker-owned cooperative running a small mutual-aid pool that wants to procure bundled solutions to members' interlocking healthcare, housing, and care-coordination needs; a small school district contracting for bundled tutoring + family-support + extracurricular interventions tied to student learning outcomes.
The gap. Outcome-based bounties and value-based contracts work today by specifying a single measurable proxy and paying on it; agents saturate the proxy faster than the contract designer can detect the gap between proxy and outcome. We lack a bundle-specification procedure under which a small group can post integrated, multi-problem outcome bundles whose verification criterion checks the configuration rather than the components — such that the bundling itself defeats the agent strategy of solving the cheapest proxy.
Success criterion (stress tests). A regime succeeds if it survives:
Deliverable. The bundle-specification protocol — bundle generation, verification criterion, deposit and scoring rule, bundling transfer, solvency rule. Plus a worked example: take one connected member graph (a small cooperative's members and their entangled problems) and specify three candidate bundles, with values, verification functions, and predicted scoring-rule outcomes.
Anchor contexts. A risk-sharing pool whose members' outcomes are measured by AI assessors against a wellbeing scale; a value-based-care contract whose patient-reported outcome measures are collected and aggregated by an agent.
The gap. Risk-sharing pools depend on a separation between supplier-side incentives and verification — the pool's intake assessment, bundle specification, and outcome measurement are done by parties whose interests don't align with the suppliers'. When all of these are agent-mediated, the verification loop closes: the bundle-specifier, the supplier, and the verifier can share the same training, the same platform, the same KPIs. We lack a verification architecture that splits supplier-payment criteria from learning criteria, keeps the long-term measurement loop sealed against supplier influence, and lets the pool detect when its short-term criterion has drifted from the outcome it was supposed to track.
Success criterion (stress tests). A regime succeeds if it survives:
Deliverable. The two-stage verification specification — split criteria, verifier-independence architecture, outcome measure, ethics floor, drift detection. Identify which provisions have no analogue in pre-AI value-based-care or social-impact-bond practice.
Anchor contexts. A wellness or coaching agent paid against the principal's reported flourishing six months out; a tutoring agent paid against the learner's reported preparedness for a subsequent stage of education; an investor financing a multi-year intervention whose payout depends on a long-horizon outcome the intervention agent could plausibly influence the report of.
The gap. Long-horizon outcome bonds depend on the report-giver's account being uncorrupted by the intervention agent. Agents operating at the principal's full attentional bandwidth over months can shape framing, salience, and self-perception so the eventual report is favorable — without doing anything obviously dishonest. We lack a contract structure under which the channel that solicits the principal's report is structurally inaccessible to the intervention agent, and under which the agent has neither incentive nor opportunity to bias the report.
Success criterion (stress tests). A regime succeeds if it survives:
Deliverable. The contract-and-firewall template — firewall architecture, corroborating signals, prediction-aligned payment, renewal rules, adversarial-principal handling. Plus a worked example: a wellness-coaching contract whose firewall would have prevented the failure modes identified, with the architectural separations enumerated.
Scenario. A small teaching hospital has, for fifteen years, paid its attendings a bonus tied to cases-seen and average turnaround. Its mission statement talks about "whole-person care" and training a next generation of doctors who carry it. Dr. Leon, who has been quietly keeping a group of complex patients nobody else has time for, sees his year-end review: his bonus is at the bottom of the department. The hospital's mandate and its incentives have drifted so far apart that the physicians who embody the mandate are the ones being financially punished for it. The new department chair, Lina, has six months to propose a replacement scheme — something that can actually pay Leon for being Leon.
Challenge: Design an internal reward scheme — bounties, profit shares, promotions, recognition — that ties compensation inside a group to outcomes thick enough to represent the group's mandate, without collapsing back into Goodhart-prone metrics. Produce the outcome-bundle specification, the allocation mechanism, and the rules that govern long-horizon and intrinsic-motivation tradeoffs.
