Participatory budgeting as an alternative to rationing
Rationing a scarce public resource by what the affected community deliberately prioritizes, rather than by who produces the most polished application. Deliberation is a signal agents can't manufacture, so the allocation stays tied to what affected people want.
The impact of agents
When AI agents let anyone produce a polished application or flood a process at will, the usual ways of rationing scarce public resources start to fail. Official discretion, price, and queue come to reward whoever has the best agent rather than the strongest claim.
What remains is running deliberation at scale without it becoming the next thing agents game.
What must be verified
Each vote counted toward the allocation must be confirmed as coming from one distinct, eligible resident, to a confidence that holds even when an agent could generate synthetic support at volume. The municipality or agency running the platform carries that duty. The vote runs on an identified channel, and the condition is the franchise rather than an integrity bar: an allocation of a community's own budget is settled by that community, so eligibility is what a vote means. Proposing and commenting are views, owed consideration on their own terms, so the platform can take them on an open channel and leave the eligible vote to decide the allocation. Say which condition each side runs under.
Protecting access
The stakes here are collective. A resident kept off the platform by poor connectivity or language barriers doesn't just lose a transaction. They cannot propose or vote, and the resulting allocation reflects only those who could take part, so they live under priorities others set. That exclusion compounds every budget round.
Keeping the path open
- Run an in-person and assisted channel at parity with the digital one, following the precedent of the original Porto Alegre assemblies.
- Take proposals and votes on paper and by phone.
- Weight nothing by channel: a ballot cast at a community meeting counts exactly as one cast on the platform.
Response surface
Residents rank projects against a published budget, with verified-identity voting online and an in-person channel running beside it.
Maturity
- Established
For allocating by deliberated community priority.
- Emerging Headline
As a deliberate response to AI-enabled gaming of effort- or quality-based rationing.
Precedents
Decidim, Barcelona's digital democracy platform. Barcelona's digital democracy platform allocated up to EUR 75 million, five percent of the overall budget, through participatory processes across four years, a figure later reduced during the pandemic. It carries resident proposals with comments and endorsements, phased deliberative processes, participatory budgeting with project sheets and public voting, and accountability dashboards tracking implementation. A city has rationed part of a real municipal budget by resident deliberation, across several budget cycles.
Consul Democracy (Madrid). Madrid's municipality launched the platform as Decide Madrid, and it supports proposals, consultations, voting, participatory budgets, and collaborative legislation. The Consul Democracy Foundation counts roughly 350 governments and civil society organizations that have used it, a cumulative count rather than a live deployment tally, while the OECD puts current reach above 100 governments. The same allocation model is running in more than a hundred governments on the OECD's count, and not in one city alone.
What carries over to agent use
Participatory budgeting platforms are transferable as rationing mechanisms where:
- Resources are geographically bounded (local infrastructure, community grants).
- Trade-offs are value-laden rather than purely technical (where to build a park, which programs to fund).
- Legitimacy requires visible community consent.
In an AI-agent context, these platforms face a specific risk: agents could generate synthetic support for proposals (astroturfing via participatory budgeting). Both Decidim and Consul require identity verification for voting, but the quality of that verification varies by deployment. The platforms' strength is that they shift the rationing question from "who can produce the best application" to "what does the community collectively prioritize", which is less susceptible to AI gaming than narrative quality.
Where things go wrong
Participatory budgeting allocates contested public resources by visible community consent rather than opaque automated scoring, so it does not produce an unexplained automated decision against an individual that they cannot see or contest. Astroturfing is this pattern's own gaming vector: an agent can generate synthetic comments and endorsements behind real, individually verified accounts, manufacturing the appearance of broad support for a proposal. Identity-bound voting caps how many votes any one resident casts; it does not stop an agent from producing the deliberation content itself.
