Is an auction where there are 2 items to allocate to bidders such that a bidder can receive only 1 item is considered a combinatoric one, even if bidders have value for receiving both items?
To my understanding it can be, e.g. a unit-price demand auction case where auction designer assumes builders are interested in one item only while in fact they may wish for more than one.
