Menu mechanisms
研究了菜单机制，即代理人在每个历史阶段从可能分配的菜单中做出选择的动态机制，分析了其在多种环境（如匹配、拍卖、学校选择）中实现规则的条件。
We investigate menu mechanisms: dynamic mechanisms where at each history, an agent selects from a menu of his possible assignments. We consider both ex-post implementation and full implementation for a strengthening of dominance that covers off-path histories, and provide conditions under which menu mechanisms provide these implementations of rules. Our results cover a variety of environments, including matching with contracts, labor markets, auctions, school choice, marriage, object allocation, and elections.
