Abstract: | Two stability concepts for one-sided matching markets are analyzed: Gale-Shapley stability and ξ-stability. The first one
applies best to markets where no status quo allocation is considered, whereas the second one is a solution to be used when
property rights are allowed. A common problem of existence is shared by both solution concepts. Hence, we study economic environments
where this problem does not exist, and present a family of agents’ preferences for which existence is guaranteed for both
Gale-Shapley stable and ξ-stable outcomes.
