We compare the performance of subjects in economic experiments run either in the lab or on a smartphone app.
Behavior is similar across samples: participants respond essentially in the same way with respect to standard behavioral measures of risk aversion, effort, focus, cognitive ability, strategic reasoning and social preferences. Participants show also similar beliefs about the actions of the other players.
We find anyway some differences: subjects on the app (i.e., outside the lab) are more prone to errors on boring tasks, prefer to provide a wrong answer rather than letting time expire, and tend to be slightly more generous and trustful with respect to the other subjects in the same session.
