Problem 3 (20 points). (a) Consider a single-item auction with player set N=[n]. Each player iinN has a private valuation v_(i) and specifies a bid b_(i). Show that in a Vickrey auction a player i might be strictly worse of by bidding b_(i)!=v_(i) than by bidding truth- fully. That is, show that for every player iinN and for every bid b_(i)!=v_(i) there is a bidding profile b_(-i) of the other players such that Nu_(i)(b_(-i),b_(i)). (b) Consider the combinatorial auction setting, where the set of players is N and the set of items is M. Assume that the auctioneer runs the VCG mechanism(Algorithm 10 in the Lecture Notes). Show that the payments (p_(i))_(iinN) com- puted by the VCG mechanism satisfy that for every player iinN,0<=p_(i)<= b_(i)(a^(*)).
