Trust and Trustworthiness Under The Prospect Theory and Quasi-Hyperbolic Preferences: A Field Experiment in Vietnam

This study incorporates risk, time, and social preferences. We conduct a field experiment in Vietnamese villages and estimate the effect of the Cumulative Prospect Theory and of quasi-hyperbolic time preferences parameters on trust and trustworthiness. We find that both probability sensitivity and risk aversion are not related to trust. Yet, more risk averse and less present biased participants are found to be trustworthier. People with longer exposure to a collectivist economy tend to have a lower level of trust and trustworthiness.
