We examine experimentally the impact of communication on trust and cooperation. Our design admits observation of promises, lies, and beliefs. The evidence is consistent with people striving to live up to others' expectations in order to avoid guilt, as can be modeled using psychological game...

A lottery is often used to allocate public rental apartments in practice. The existing random assignments in the literature do not apply to public rental apartments because practical constraints are more restrictive. We provide a lottery-TTC algorithm to find a lottery allocation that has two...

This paper provides a survey of recent experimental work in economics focusing on social and economic networks. The experiments consider networks of coordination and cooperation, buyer-seller networks, and network formation

How can we maximize the common good? This is a central organizing question of public policy design, across political parties and ideologies. The answer typically involves the provisioning of public goods such as fresh air, national defense, and knowledge. Public goods are costly to produce but...

In the Ultimatum Game (UG) one player, named “proposer”, has to decide how to allocate a certain amount of money between herself and a “responder”. If the offer is greater than or equal to the responder’s minimum acceptable offer (MAO), then the money is split as proposed, otherwise,...

Ultimatum games have been extensively used in experimental studies. By studying the consequences that restrictions shared by ultimatum games have in subject's behaviour, this paper argues that some results are falsified by design constraints. This paper also presents a taxonomy of certification,...

We investigate how the intentionality of investors or trustees’ actions affects thirdparty compensation and punishment interventions after a trust game. Investorsand trustees are randomly assigned to conditions where they either makeintentional choices or their choices are made by a random...

Whether or not to vaccinate one’s child is a decision that a parent may approach in several ways. The vaccination game, in which parents must choose whether to vaccinate a child against a disease, is one with positive externalities (herd immunity). In some societies, not vaccinating is an...

Game harmony is a generic game property that describes how harmonious (non-conflictual) or disharmonious (conflictual) the interests of players are, as embodied in the payoffs. It can be used to predict the relative degree of cooperation in games of different harmony. For a large enough increase...
