ABSTRACT
We describe a reputation-driven market that motivates human computation sellers (workers) to produce optimal levels of quality when quality is not immediately measurable and contracts specifying the level of quality cannot be enforced. We consider the implications of making quality instantaneously verifiable up to a known threshold ("partial verification"), as might be the case when the market maker possesses a sufficiently advanced artificial intelligence apparatus. We find that such a verification system allows the market to attain a Pareto optimal equilibrium with less patient workers, and, in addition, makes the market more resistant to pseudonym attacks.

Efficiency through feedback-contingent fees and rewards in auction marketplaces with adverse selection and moral hazard
EC '03: Proceedings of the 4th ACM conference on Electronic commerceThis paper proposes a novel mechanism for inducing cooperation in online auction settings with noisy monitoring of quality and adverse selection. The mechanism combines the ability of electronic markets to solicit feedback from buyers with the more ...
The Nature and Role of Feedback Text Comments in Online Marketplaces: Implications for Trust Building, Price Premiums, and Seller Differentiation
For online marketplaces to succeed and prevent a market of lemons, their feedback mechanism (reputation system) must differentiate among sellers and create price premiums for trustworthy sellers as returns to their reputation. However, the literature ...
Reputation Mechanism Design in Online Trading Environments with Pure Moral Hazard
This paper offers a systematic exploration of reputation mechanism design in trading environments with opportunistic sellers of commonly known cost and ability parameters, imperfect monitoring of a seller's actions, and two possible seller effort levels,...
