摘要:We derive optimal strategies for a bidding agent that participates in multiple,
simultaneous second-price auctions with perfect substitutes. We prove that, if
everyone else bids locally in a single auction, the global bidder should always
place non-zero bids in all available auctions, provided there are no budget
constraints. With a budget, however, the optimal strategy is to bid locally if
this budget is equal or less than the valuation. Furthermore, for a wide range
of valuation distributions, we prove that the problem of finding the optimal
bids reduces to two dimensions if all auctions are identical. Finally, we
address markets with both sequential and simultaneous auctions, non-identical
auctions, and the allocative efficiency of the market.
