By: Lauren Cohen, Umit Gurun and Scott Duke Kominers
We survey the empirical literature on non-practicing entity (NPE) litigation behavior and its consequences. We document both aggregate trends and cross-sectional differences amongst various types of NPEs. Survey evidence illustrates a number of ways in which NPEs can... View Details
