Matching with Couples: Stability and Incentives in Large Markets*
研究了在医生和心理学家的集中劳动力市场中，夫妻同时申请两个职位时稳定匹配的存在条件，发现当夫妻数量少且偏好列表短时稳定匹配存在，并讨论了激励问题。
Abstract Accommodating couples has been a long-standing issue in the design of centralized labor market clearinghouses for doctors and psychologists, because couples view pairs of jobs as complements. A stable matching may not exist when couples are present. This article’s main result is that a stable matching exists when there are relatively few couples and preference lists are sufficiently short relative to market size. We also discuss incentives in markets with couples. We relate these theoretical results to the job market for psychologists, in which stable matchings exist for all years of the data, despite the presence of couples.
