On the External Validity of Social- Preference Games: A Systematic Lab-Field Study

We present a lab-field experiment designed to assess systematically the external validity of social preferences elicited in a variety of experimental games. We do this by comparing behavior in the different games with a number of behaviors elicited in the field and with self-reported behaviors exhibited in the past, using the same sample of participants. Our results show that the experimental social-preference games do a poor job in explaining both social behaviors in the field and social behaviors from the past.
