Abstract
This short comment on the presentation by Professor KAMEMOTO Hiroshi is to explore the new waves in economic analysis of law. understood as a methodology to model and evaluate the society. I showed that theories and findings in various academic fields such as brain science, cognitive science, social psychology, computer simulation, and evolutionary theory are enriching the scholarship of law & economics as well as economics. I concluded this comment by saying that abstract debate on a methodology would be of little value and that constructive criticism on concrete findings should be welcome.
