Many economic interactions rely on trust, which is sometimes violated. The fallout from business fraud and other malfeasance shows serious economic consequences of trust violations. Simple rules mandating minimum standards are attractive because they prevent the most egregious trust violations....

Using trust games, we study how promises and messages are used to build new trust where it did not previously exist and to rebuild damaged trust. In these games, trustees made non-binding promises of investment-contingent returns, then investors decided whether to invest, and finally trustees...

Despite normative predictions from economics and biology, unrelated strangers will often develop the trust necessary to reap gains from one-shot economic exchange opportunities. This appears to be especially true when declared intentions and emotions can be cheaply communicated. Perhaps even...

We observed reports of conflicted (concurrent positive and negative) emotions activated after interactions in the Trust game. Our analyses reveal that activation of 20 emotional states following trust-based interaction is better explained by predictions derived from a multi-dimensional...

Many economic interactions are characterized by “all-or-nothing” action spaces that may limit the demonstrability of intended trust. We investigate whether restricting investment opportunities to all-or-nothing options affects the investment rate and propensity to reciprocate. We do this by...

We examine how taxes impact charitable giving and how this relationship is affected by the degree of wasteful government spending. In our model, individuals make donations to charities knowing that the government collects a flat-rate tax on income (net of charitable donations) and redistributes...

Individuals participating in a group conflict have different preferences, e.g., maximizing their own payoff, maximizing the group’s payoff, or defeating the rivals. When such preferences are present simultaneously, it is difficult to distinctly identify the impact of those preferences on...

We conduct an experimental analysis of a best-of-three contest. Intermediate prizes lead to higher efforts, while increasing the role of luck (as opposed to effort) leads to lower efforts. Both intermediate prizes and luck reduce the probability of contest ending in two rounds. The patterns of...

A common finding in social sciences is that member change hinders group functioning and performance. However, questions remain as to why member change negatively affects group performance and what are some ways to alleviate the negative effects of member change on performance? To answer these...

We examine behavior in a three-player trust game in which the first player may invest in the second and the second may invest in the third. Any amount sent from one player to the next is tripled. The third player decides the final allocation among three players. The baseline treatment with no...
