The endogenous nature of the measurement of social preferences

Abstract

We present evidence against the standard assumptions that social preferences are stable and can be measured in a reliable, nonintrusive manner. We find evidence that measures of social preferences can affect subsequent behaviour.

Researchers often measure social preferences by posing dictator type allocation decisions. The social value orientation (SVO) is a particular sequence of dictator decisions.

We vary the order in which the SVO and a larger stakes dictator game are presented. We also vary the form of the dictator game.

In one study, we employ the standard dictator game, and in the other, we employ a nonstandard dictator game. With the standard dictator game, we find that prosocial subjects act even more prosocially when the SVO is administered first, whereas selfish subjects are unaffected by the order.

With the nonstandard dictator game, we find evidence across all subjects that those who first receive the SVO are more generous in the dictator game but we do not find the effect among only the generous subjects.

Across both dictator game forms, we find evidence that the subjects who are first given the SVO were more generous than subjects who are given the SVO last. We also find that this effect is stronger among the subjects with a perfectly consistent SVO measure.

Although we cannot determine whether the order affects preferences or the measure of preferences, our results are incompatible with the assumptions that social preferences are stable and can be measured in a reliable, nonintrusive manner.
