Armin Falk, Stephan Meier, and Christian Zehnder. Do Lab Experiments Misrepresent Social Preferences? The case of self-selected student samples.

Social preference research has received considerable attention among economists in recent years. However, the empirical foundation of social preferences is largely based on laboratory experiments with self-selected students as participants. This is potentially problematic as students participating in experiments may behave systematically di erent than non-participating students or non-students. In this paper we empirically investigate whether laboratory experiments with student samples misrepresent the importance of social preferences. Our rst study shows that students who exhibit stronger prosocial inclinations in an unrelated eld donation are not more likely to participate in experiments. This suggests that self-selection of more prosocial students into experiments is not a major issue. Our second study compares behavior of students and participants recruited from the general population in a trust experiment. In general, we nd very similar behavioral patterns for the two groups, but non-students make signi cantly more generous repayments suggesting that results from student samples might be seen as a lower bound for the importance of prosocial behavior.
