In 2006, approximately 49% of violent crimes were not reported to police. Being the victim of sexual assault is expensive; each incident imposes an external cost of over $100k on the victim. However, recent estimates of the total social cost are an order of magnitude larger suggesting that from a social welfare standpoint rape is likely to be underreported if the victim's demand for reporting is price elastic. In spite of the centrality of victim reporting in the functioning of the criminal justice system, to date there is very little systematic evidence on what governments can do to encourage victims to report crimes. We estimate the sensitivity of victims to the cost of reporting in an Alaskan city between 1993 and 2006, during which time a chief of police publicly supported a policy of charging victims of sexual assault for medical procedures required to collect evidence against their attackers. Using a triple differences approach that compares trends in reported sexual assaults to other index crimes over time and across Alaskan cities, we estimate that this shift in cost of approximately $1,200 from the city government to victims reduced the number of reported rapes by between 50 and 80%. This large response highlights the importance of public policies which reduce the private cost of reporting crime.
