Abstract This paper studies how punishment affects future compliance behavior and isolates deterrence effects mediated by learning. Using administrative data from speed cameras that capture the full driving histories of more than a million cars over several years, we evaluate responses to at extensive (receiving speeding ticket) intensive margins (tickets with higher fines). Two complementary e...

"Who did it?" Attribution, some may argue, is a challenge "as old as crime and punishment." In the cyber realm too, criminal attribution is a key delineating factor between cybercrime and other threats. When investigating a given incident, law enforcement is challenged with tracing the action to its source and determining whether the actor is a criminal or whether the actor may be a terrorist o...
