Solution concepts in social environments use either a direct or indirect dominance relationship, depending on whether it is assumed that agents are myopic or farsighted. Direct dominance implies indirect dominance, but not the reverse. Hence, the predicted outcomes when assuming myopic (direct)...

Sasaki and Toda (1996) claim that, in marriage markets with externalities, the stable set and the core are not equal, differently to what happen in marriage markets without externalities. However, the example that proves this claim has an error. By proposing an alternative example we prove that...

In persuasion problems where the receiver's action is one-dimensional and his utility is single-peaked, optimal signals are characterized by duality, based on a first-order approach to the receiver's problem. A signal is optimal if and only if the induced joint distribution over states and...

This book introduces a new rationalistic approach towards the formalization of Schelling's concept of focal points within a general game-theoretic framework. The focus is on focal points as a symmetry-breaking device. Hence, focal points in coordination games can be explained while focal points...

In this paper, we study marriage formation through a two-sided secretary problem approach. We consider individuals with nontransferable utility and two different dimensions of heterogeneity, a characteristic evaluated according to the idiosyncratic preferences of potential partners, and a...

We consider one-to-one matching problems under two modalities of uncertainty that differ in the way types are assigned to agents. Individuals have preferences over the possible types of the agents from the opposite market side and initially know the “name” but not the ”type” of the other...

Stability is often the goal for clearinghouses in matching markets, such as those matching residents to hospitals, students to schools, etc. Stable outcomes absent transfers need not be utilitarian efficient, suggesting the potential value of transfers. We study the wedge between stability and...
