This study discusses a related approach that has increasingly grown in prominence of late--field experiments. I argue that field experiments serve as a useful bridge between data generated in the lab and empirical studies using naturally-occurring data. In discussing this relationship, I highlight that field experiments can yield important insights into economic theory and provide useful guidance to policymakers. I also draw attention to an important methodological contribution of field experiments: they provide an empirical account of behavioral principles that are shared across different domains. In this regard, at odds with conventional wisdom, I argue that representativeness of the environment, rather than representative of the sampled population, is the most crucial variable in determining generalizability of results for a large class of experimental laboratory games.
