Each bidder in the auction may submit (possibly multiple) bids ...
Auctions. A Vickrey–Clarke–Groves (VCG) auction is a type of sealed-bid auction of multiple items. Bidders submit bids that report their valuations for the items, without knowing the bids of the other bidders.

In multi-unit auctions, a bid for one unit may affect payments for other units won, giving rise to an incentive to shade bids differently across units. They establish that such differential bid shading results generically in ex post inefficient allocations in the uniform-price and pay-as-bid auctions.
A combinatorial auction is a type of smart market in which participants can place bids on combinations of discrete heterogeneous items, or “packages”, rather than individual items or continuous quantities. These packages can be also called lots and the whole auction a multi-lot auction. [1] Combinatorial auctions are applicable when bidders ...
