Respect for Improvements and Comparative Statics in Matching Markets. Scott Duke Kominers, August 21, 2019, Paper, "One of the oldest results in the theory of two-sided matching is the entry comparative static, which shows that under the Gale–Shapley deferred acceptance algorithm, adding a new agent to one side of the market makes all the agents on the other side weakly better off. Here, we give a new proof of the entry comparative static, by way of a well-known property of deferred acceptance called respect for improvements. Our argument extends to yield comparative static results in more general settings, such as the matching with slot-specific preferences framework." Link
