Crime and Political Effects of a Concealed Carry Ban in Brazil, talk by Rodrigo Schneider, assistant professor of economics, Skidmore College.
This paper studies the effects of legislation in Brazil that banned concealed carry nationwide in 2003, and provided for a voter referendum 22 months later regarding whether to ban the sale of all firearms.
Using a regression discontinuity design, I find that gun-related homicides decreased by 12.2 percent, with the reduction especially pronounced in high-crime areas and among black males. Other crimes involving guns also declined. There is no evidence of substitution effect as non-gun-related homicides were not affected.
Two pieces of evidence suggest that the mechanism explaining this result is a decrease in the number of people carrying gun in response to the legislation: first, the number of illegal gun carrying decreased and second, only gun-related homicides taking place outside the residence were reduced.
Analysis of the subsequent voter referendum, which was defeated by a wide margin, shows stronger support for the complete weapons ban in the areas more affected by gun violence.
