A few days ago, I linked to an article documenting a connection between reduced crime and increased exposure to violent movies. Now it appears that porn has a similar effect, and that the increased availability of porn has led to a significant decrease in rape and attempted rapes by young men:

The arrival of the internet caused a large decline in both the pecuniary and non-pecuniary costs of accessing pornography. Using state-level panel data from 1998-2003, I find that the arrival of the internet was associated with a reduction in rape incidence. However, growth in internet usage had no apparent effect on other crimes. Moreover, when I disaggregate the rape data by offender age, I find that the effect of the internet on rape is concentrated among those for whom the internet-induced fall in the non-pecuniary price of pornography was the largest – men ages 15-19, who typically live with their parents.
