Example text

However, in terms of calculating the payments to the agents, our mechanism does impose a larger computational load. In the case of the VCG mechanism, calculating the payment involves performing the winner determination problem |I| times over the reduced set of agents I \ i (see [5] for more details). However in our case, the centre needs to successively reduce the value of A Mechanism for Multiple Goods and Interdependent Valuations 27 the report from each agent (and calculate the optimal allocation at each stage) until it reaches an allocation which is the optimal one for the reduced set of agents I \ i (see equations 2 and 3).

Agent A4 has improved its own utility from -3 to +3, but the true overall utility has decreased from +4 to -2. Other agents may follow similar reasoning and perturb the result further. 34 3 B. Faltings Achieving Incentive-Compatibility The incentives of each agent can be aligned with those of the group by making each agent pay a tax reflecting the cost that their preferences are causing to others. A well-known mechanism is the Vickrey-Clarke-Groves (VCG) tax mechanism ([14,5,8]). Its application for multi-agent decision making has already been proposed in [6].

Note that while auctions are a special case of social choice, reverse and double auctions as the outcome space is not independent of the agents (an agent may not agree to give up an item). In an incentive-compatible (IC) mechanism, the incentives of each agent are aligned with those of the group: the behavior that optimizes the utility of an individual agent also optimizes the utility of the group. When utility optimization is left to the social choice mechanism, this often corresponds to each agent being best off declaring its preferences truthfully; this is called truthful or strategyproof.
