The availability of more data and new ways of analyzing it is changing the way we do empirical legal research. With the help of modern technology we can study adjudicators, awards and agreements in greater numbers, less time and more detail opening the doors for new research questions, theory building and legal technology applications for scholars and practitioners. This introduction to the Journal of International Economic Law Special Issue on new frontiers in empirical legal research provides a first take on this data-driven future. It distinguishes data-driven research from more traditional methods by pointing to (1) its "data first" attitude, (2) its ambition to look at all the available data rather than subsamples thereof and (3) its focus on computing rather than reading or counting. Data-driven research comes with new promises, but also challenges and limitations. While it allows researchers to uncover latent structures, debunk past myths and even forecast the future, it also requires new skills and competencies including an ability to tell patterns from noise in inductive data analysis. We argue that the time is ripe to overcome these challenges and to seize the opportunities of the new data-driven frontier in empirical legal scholarship.
