We study a new monotonicity problem in combinatorial auctions called goods revenue　monotonicity, which requires that the auctioneer earn no more revenue by dropping goods from the endowments. Although no mechanism satisfies goods revenue monotonicity together with strategy-proofness,...

When encountering a set of alternatives displayed in the form of a list, the decision maker usually determines a particular alternative, after which she stops checking the remaining ones, and chooses an alternative from those observed so far. We present a framework in which both decision...

This paper studies a two-player machine (finite automaton) game in which an extensive game with perfect information is infinitely repeated. We introduce a new measure of strategic complexity named "multiple complexity", which considers the responsiveness of a strategy to information as well as...
