Using new methods, we measure the intensities of higher-order risk preferences (prudence and temperance) in an incentivized experiment with 658 adolescents. Aligned with theory, we find that higher-order risk preferences are strongly related to field behavior, including prevention, health, addictive behavior, and financial decision-making. Most importantly, we show that ignoring prudence and temperance can yield misleading conclusions about the relation of risk preferences to field behavior, and that survey measures of risk tolerance often relate to field behavior because they capture higher-order risk preferences.

In markets with asymmetric information between sellers and buyers, feedback mechanisms are important to increase market efficiency and reduce the informational disadvantage of buyers. Feedback mechanisms might work because of self-selection of more trustworthy sellers into markets with such mechanisms or because of reputational concerns of sellers. We show in a field experiment how to disentangle self-selection from reputation effects. Based on 476 taxi rides with four different types of taxis, we find strong evidence for reputation effects but little support for self-selection effects. We discuss policy implications of our findings.
