We conduct online field experiments in large real-world social networks in order to decompose prosocial giving into three components: (1) baseline altruism toward randomly selected strangers, (2) directed altruism that favors friends over random strangers, and (3) giving motivated by the...

The design of the New York City (NYC) high school match involved trade-offs among efficiency, stability, and strategy-proofness that raise new theoretical questions. We analyze a model with indifferences -- ties -- in school preferences. Simulations with field data and the theory favor breaking...

Rights of first refusal are contract clauses intended to provide the holder of a license or lease with some protection when the contract ends. The simplest version gives the right holder the ability to act after potential competitors. However, another common implementation requires the right...

Many markets encounter difficulty maintaining a thick marketplace because they experience transactions made at dispersed times. To address such problems, many markets try to establish norms concerning when offers can be made, accepted, and rejected. Examining such markets suggests it is...

Erev, Ert, and Roth organized three choice prediction competitions focused on three related choice tasks: one shot decisions from description (decisions under risk), one shot decisions from experience, and repeated decisions from experience. Each competition was based on two experimental...
