Though individuals prefer to join groups with high quality peers, there are also advantages from being high up in the pecking order within a group. We show that sorting of agents in this environment results in an overlapping interval structure in the type space. Segregation and mixing coexist in...

Though individuals prefer to join groups with high quality peers, there are advantages to being high up in the pecking order within a group if higher ranked members of a group have greater access to the group's resources. When two organizations try to attract members from a ¯xed population of...

This paper considers a model of a rating agency with multiple clients. Each client has a separate market (end-user of the rating); the only connection among them is that the underlying qualities of the clients are correlated. In the benchmark case of individual rating, the market for each client...

We consider a two-sided, finite-horizon search and matching model with heterogeneous types and complementarity between types. The quality of the pool of potential partners deteriorates as agents who have found mutually agreeable matches exit the market. When search is costless and all agents...

We study how competing matchmakers use prices to sort participants into search markets, where they form random pairwise matches, and how equilibrium outcomes compare with monopoly in terms of prices, search market structure and sorting efficiency. The role of prices to facilitate sorting is...

This paper considers the problem of a monopoly matchmaker that uses a schedule of entrance fees to sort different types of agents on the two sides of a matching market into exclusive meeting places, where agents randomly form pairwise matches. We make the standard assumption that the match value...
