Trust and trustworthiness under information asymmetry and ambiguity

We introduce uncertainty and ambiguity in the standard investment game. In the uncertainty treatment, investors are informed that the return of the investment is drawn from a publicly known distribution function. In the ambiguity treatment, investors are not informed about the distribution function. We find that both trust and trustworthiness are robust to the introduction of these changes. •Study the effect of uncertainty and ambiguity in the standard investment game.•Measures of trust and trustworthiness are robust to both uncertainty and ambiguity.•Proportion of individuals who send zero is marginally higher (10% significance level) under ambiguity compared to the baseline.
