Behavioral law and economics : empirical methods

Originally, behavioral law and economics was an exercise in exploring the implications of key findings from behavioral economics (and psychology) for the analysis and reform of legal institutions. Yet as the new discipline matures, it increasingly replaces foreign evidence by fresh evidence, directly targeted to the legal research question. This chapter surveys the key methods: field evidence, survey data, vignette and lab experiment, discusses their pros and cons, illustrates them with key publications, and concludes with methodological paths for fu-ture development. It quantifies statements with descriptive statistics about the 77 behavioral papers that have been published in the Journal of Empirical Legal Studies since its foundation until the end of 2012. -- behavioral law and economics ; law and psychology ; criminology ; field data ; survey data ; vignette ; lab experiment
