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...

Credence-goods experiments have focused on stylized settings in which experts can perfectly identify the buyer’s best option and that option works without fail. However, in nature, credence goods involve uncertainties that complicate assessing the quality of service and advice. We introduce...

We study a dynamic model of self-control where the history of one's decisions has influence on subsequent decision making. In our model effort and guilt are negative emotions produced by previous decisions to either resist or yield to temptation, respectively. When recalled, these emotions...

Little is known about why humans have an extended juvenile development and long post-reproductive lifespan. While older adults’ non-material contributions to younger generations can help explain human life history, even less is known about development of skills and abilities in small-scale...

We study a dynamic model of self-control where the history of one's decisions (understood as emotions) has influence on subsequent decision making. We propose that effort and regret are emotions produced by previous decisions to either resist or yield to temptation, respectively. When recalled,...

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...

Though individuals differ in the degree to which they are predisposed to trust or act trustworthy, we theorize that trust-based behaviors are universally determined by the calibration of conflicting short- and long-sighted behavior regulation programs, and that these programs are calibrated by...

Many economic interactions are characterized by “all or nothing” action spaces that may limit a demonstrable index of trust and, therefore, the propensity to reciprocate. In two experimental trust games, the action space governing investments was manipulated to examine the effects on...
