Maurice E. Schweitzer, Teck H. Ho, and Xing Zhang. "How Monitoring Influences Trust: A Tale of Two Faces." Management Science, 2016
In a repeated trust game, we found that trustees and trustors responded to monitoring in an asymmetric manner: trustees strategically responded to monitoring, returning more money than they received when they anticipated that they would be monitored, but returning less than they received when they anticipated that they would not be monitored. Trustors, however, failed to anticipate how opportunistic their counterparts would behave when they were not monitored.

Teck H. Ho, Ming Hsu, Xing Zhang, and Songfa Zhong "Understanding Other-regarding Mechanisms in Heterogeneous Populations"
In a series of laboratory experiments, we systematically manipulate the mechanism by which a third party can either subtract selfish individuals' well beings or increase less well-off individuals' well beings. We found that punishment restored social justice better than subsidy. We developed and calibrated a general utility model using the experimental data. We simulated how changes in the proportion of prosocial individuals in a society might influence the relative merit of the punishment and the subsidy mechanisms. We found that the success of a prosocial mechanism depends on the underlying heterogeneity in the population.

Oxytocin is the paramount human social hormone modulating social cognition and affiliative behaviors. Drawing on the extant literature on social aspects of buying behavior, we found that people with higher plasma oxytocin levels, are associated with higher scores in multiple measures of buying tendency, and people with higher plasma oxytocin level spend more on conspicuous goods. All the effects are driven by females.
