Not only do these approaches centralize power, they also don’t actually re-align markets: markets continue to pull the wrong way, patched by pledges, regulations, or redistributions.
Powerful AI changes all three of these factors: it can extend the assessment of benefit into quantitative domains; it can make assessment much cheaper; and it can occupy a third-party, auditable position to eliminate information asymmetry in contract design. Outcome-based contracting can thus be extended to many more markets—even in domains with fuzzy assessment needs, where measuring ‘good outcomes’ requires qualitative interviews.
To illustrate the components of a market intermediary, let's imagine building one for car repair, a classic market with high information asymmetry.
A market intermediary needs to cover four functions:
Assessment. First, it needs to track the kinds of benefit that consumers are asking for and which providers think they can provide, and then track whether that benefit works out in the end. In the case of car repair, the intermediary would need to know how long somebody wants their car to continue running well, whether they care about visual polish or just engine health, etc. And it would need to either interview the car owner periodically, to see how the car‘s doing, or otherwise access data about ongoing car health.
There are two important challenges here. First, we must avoid using proxy measures that diverge from the real benefit the market provides. All important elements of benefit must be captured, or they will be stripped from the market. For instance, if repair shops turn out to provide an important role in educating drivers, that information needs to be gathered and tracked by the intermediary.
Secondly, the intermediary must be robust against incentives that providers will have to game the system. For instance, auto repair shops may try to pay their customers to say their car is running better than it is. Intermediaries will need to detect and avoid this kind of fraud.
An intermediary’s matching function finds provider/consumer pairs which it believes would provide benefit with an acceptable price. This requires additional data: wait times, locations, and hours of different providers, how good they are at visual polish vs engine health, etc.
We can consider the intermediary's job as finding the actual cost of each marginal unit of benefit, for each consumer. In our car repair case, how much would it cost to make each car run one year longer, or look a bit better, etc? To make this possible, providers can publish a price list and consumers can say what they’d pay for a unit of benefit[3].
In optimization, this list of matches can be further ranked and pruned. In most markets, it doesn’t make sense to pick the cheapest proposed transaction, but rather to find something optimal on the frontier between benefit/cost trade-offs.
We are excited to try using ML to do this without making benefit (and benefit uncertainty) into a single number.
