To estimate peer effects in college achievement we exploit a unique dataset in which individuals have been exogenously assigned to peer groups of about 30 students with whom they are required to spend the majority of their time interacting. This feature enables us to estimate peer effects that...

The antitrust laws are intended to permit procompetitive actions by firms and deter anticompetitive actions. We consider firms' incentives to use the antitrust lawsuits for strategic purposes, in particular to prevent procompetitive efficiency-improvement by rival firms. Our main result is that,...
