Abstract

In comparison to traditional laboratory experiments, internet-based experiments reduce the experimental subject’s opportunity costs. Consequently, the samples of these two experiments will likely be different in spite of size and composition. This finding is important to consider when interpreting economic experiments because self-selection may bias the external validity of experiments.
