Although no stable matching mechanism can induce truth-telling as a dominant strategy for all participants (Roth, 1982), recent studies have presented conditions under which truthful reporting by all agents is close to optimal (Immorlica and Mahdian, 2005, Kojima and Pathak, 2009 and Lee,...

In variants of the Electronic Mail Game (Rubinstein, 1989) where two or more players communicate via multiple channels, the multiple channels can facilitate collective action via redundancy, the sending of the same message along multiple paths or else repeatedly along the same path (Chwe, 1995...

A collaboration of medical professionals with economists and computer scientists involved in ?market design? had led to the redesign of the clearinghouse assigning medical students to internships in Israel. The new mechanism presents significant efficiency gains relative to the previous one, and...

We study a model of mechanism design in which the designer cannot force the players to use the mechanism. Instead they must voluntarily sign away their decision rights, and if they instead keep their decision rights they act on their own accord. We ask what social choice functions can be...

In a centralized marketplace that was designed to be simple, we identify participants whose choices are dominated. Using administrative data from Hungary, we show that college applicants make obvious mistakes: they forgo the free opportunity to receive a tuition waiver worth thousands of...

Stability and "no justified envy" are used almost synonymously in the matching theory literature. However, they are conceptually different and have logically separate properties. We generalize the definition of justified envy to environments with arbitrary school preferences, feasibility...

We review the process of redesigning the Israeli Psychology Masters Match (IPMM), with special attention given to the fellowships granted by the departments and the interplay between different programs within the same department. These features make the IPMM a two-sided matching with contracts...

Although many centralized school assignment systems use strategically simple mechanisms, applicants often make dominated choices. Using administrative data from Hungary, we show that many college applicants forgo the free opportunity to receive a tuition waiver. Using two empirical strategies,...
