"Punishment and Specific Deterrence: Evidence from Speeding Tickets"
Abstract:
This paper studies how exposure to punishment - which may induce learning about law enforcement - shapes future compliance behavior. The context of our study
is the enforcement of speed limits through radars and speeding tickets. Tickets do not affect the future “price” for speeding (i.e., expected fines, insurance rates). Hence, there is no scope for general deterrence effects. Using unique data on driving and
ticketing histories that track more than 1 million cars over almost 4 years, we evaluate drivers' responses to punishment at the extensive (receiving a speeding ticket) and intensive margin (tickets with low vs high fines). We use two complementary empirical
strategies: (1) A regression discontinuity design that builds on speed level cutoffs used in the enforcement process and (2) an event study deign that exploits high-frequency data to compare driving before and after receiving a ticket. Both analyses provide
coherent evidence, documenting a strong and persistent specific deterrence effect from receiving a ticket. Drivers reduce their speed immediately after receiving a ticket. The drop in speeding is sustained over several months. However, we find no evidence
that intensive margin variation in punishment related to a more than two-fold increase in fines amplifies the impact of speeding tickets.
