... utility, and that a mechanism is (economically) efficient if it always maximized the sum of utilities for all agents. In addition, a mechanism for a quasi-linear problem is said to be budget balanced ... here is one economic shortcoming. Recall that a mechanism is incentive compatible (in dominant strategies) if it leads to a game in which it is a dominant strategy for each agent to disclose his ... this extension is also straightforward. A Bayesian mechanism design problem is a distribution over a set of utility functions and a partition over this set for each agent; a mechanism remains...

... agents bid at their own pace and as many times as they want. Each bid consists of a price and quantity, where the quantity is either positive (signifying a ‘buy’ order) or negative (signifying a ‘sell’ ... various auction protocols. 7.4 Combinatorial auctions As mentioned briefly above, combinatorial auctions are auctions in which mul- tiple goods are being auctioned simultaneously. In a combinatorial ... questions you might ask. First, as a bidder you might want to know what you can bid; in other words, what kinds of bids are you permitted to submit.

... atomic bid. An atomic bid is a pair (S, p) which indicates that the agent is willing to pay a price of p for the subset of goods S. Note that an atomic bid implicitly represents an AND operator ... Myerson-Satterthwaite impossibility theorem, which states that no mechanism can be simultaneously incentive com- patible, efficient, and budget balanced. In particular, it follows that the VCG 7.4. COMBINATORIAL ... Thus it is natural to be concerned about the computational complexity of a given bidding language. In particular, we may want to know how difficult it is to take an arbitrary bid in some language and...
