Dynamically stable matching
针对双边动态匹配市场提出动态稳定性概念，解决代理不同时可用和外部性问题，证明动态稳定匹配总是存在，并确保代理及时参与。
I introduce a stability notion, dynamic stability , for two‐sided dynamic matching markets where (i) matching opportunities arrive over time, (ii) matching is one‐to‐one, and (iii) matching is irreversible. The definition addresses two conceptual issues. First, since not all agents are available to match at the same time, one must establish which agents are allowed to form blocking pairs. Second, dynamic matching markets exhibit a form of externality that is not present in static markets: an agent's payoff from remaining unmatched cannot be defined independently of other contemporaneous agents' outcomes. Dynamically stable matchings always exist. Dynamic stability is a necessary condition to ensure timely participation in the economy by ensuring that agents do not strategically delay the time at which they are available to match.
