In a bargaining setting with asymmetrically informed, inequity-averse parties, a fully efficient mechanism (i.e., the double auction) exists if and only if compassion is strong. Less compassionate parties do not trade in the double auction in the limit of strong envy.

We show that the commitment to not allocate may be exploited by a seller/social planner to increase the expected social surplus that can be achieved in the sale of an indivisible unit.

This note shows that in the matching-with contracts model, the outcome of the cumulative offer process is order-independent if every hospital has a choice function that satisfies the bilateral substitutability condition and the irrelevance of rejected contracts condition.

In the matching with contracts literature, three well-known conditions (from stronger to weaker)–substitutes, unilateral substitutes (US), and bilateral substitutes (BS)–have proven to be critical. This paper aims to deepen our understanding of them by separately axiomatizing the gap between...

We derive several implications of incentive compatibility in general (i.e., not necessarily quasilinear) environments. Building on Kos and Messner (2013), we provide a (partial) characterization of incentive compatible mechanisms.

This paper describes a nearly optimal auction mechanism that does not require previous knowledge of the distribution of values of potential buyers. The mechanism we propose builds on the new literature on the elicitation of information from experts. We extend the latter to the case where the...

We extend the gross substitutes and complements framework (Sun and Yang, 2006). Competitive equilibrium with indivisible goods exists under significantly weaker, intuitive and interpretable conditions. A generalized dynamic double-track procedure (Sun and Yang, 2008, 2009) finds the competitive...

We provide a simple example demonstrating that the unconditional revelation information in a war of attrition with private budget constraints can decrease expected revenue. Our example suggests that information non-revelation can counteract the adverse revenue impact of budget constraints and...

We compare dictator and impunity games. In impunity games, responders can reject offers but to no payoff consequence to proposers. Because proposers act under impunity, we should expect the same behavior across games, but experimentally observed behavior varies. Responders indeed exercise the...

In the many-to-one matching model with contracts, I provide new necessary and new sufficient conditions for the existence of a stable allocation. These new conditions exploit the fact that one side of the market has strict preferences over individual contracts.
