Can We Infer Social Preference from the Lab? Evidence from the Trust Game

We show that a measure of reciprocity derived from the Berg et al. (1995) trust game in a laboratory setting predicts the reciprocal behavior of the same subjects in a real-world situation. By using the Crowne and Marlowe (1960) social desirability scale, we do not find any evidence that a desire to conform to social norms distorts results in the lab, yet we do find evidence that it affects results in the field.
