We develop a network-flow approach for characterizing interim-allocation rules that can be implemented by ex post allocations. Our method can be used to characterize feasible interim allocations in general multi-unit auctions where agents face capacity constraints, both ceilings and floors....

We study the Generalized Second Price auctions – a standard method for allocating online search advertising – experimentally, considering both the static environment assumed by the prevailing theory and a dynamic game capturing the salient aspects of real-world search advertising auctions....
