It’s the Phone, Stupid: Mobiles and Murder Lena Edlund and Cecilia Machado
NBER Working Paper No. 25883 May 2019
New York City, Los Angeles, and Chicago. In 1990, they
accounted for 5.6% of the US population but 20% of homicides, and had homicide rates
exceeding not only the national average but also those of other cities. Ten years later, the
country’s three most populous cities looked like any other city, a remarkable convergence
Our main finding is that annual, county-level mortality data for the contiguous US
covering the four decades 1970-2009 lend support to our hypothesis that expansion of
cellular phone service – as proxied by antenna-structure build-out – lowered homicide
rates.
AAQ: see table 3-5 where R2 is 70%+, that is linear regression of crime rates by antenna density explains 80% of variation over counties or metropolitan areas.

Mobile Network Outages and Violence Against Women: Evidences from Brazil
7 Sep 2022
Antonio Vinícius Barbosa UFPB
Jorge H. N. Viana Department of Economics – UFPB
Using high-frequency data from Brazil, we show that the disruption caused by the mandatory 9-digit dialing transition for cell phone numbers had unintended consequences, increasing hospitalization among women victims of violence. The pattern we observe is consistent with the argument that mobile phones can provide accessibility for women in risky situations while also changing offenders’ perceptions.
