Media and Crime Perceptions: Evidence from Mexico
利用墨西哥2011年媒体减少暴力报道的协议，研究发现媒体曝光度高的个体犯罪感知下降，但实际回避行为未变。
Abstract This article examines whether individuals’ crime perceptions and crime avoidance behavior respond to changes in crime news coverage. I use data from Mexico, where major media groups agreed to reduce coverage of violence in March 2011. Using a unique dataset on national news content and machine learning techniques, I document that after the Agreement, crime news coverage on television, radio, and newspapers decreases relative to the national homicide rate. Using survey data, I find robust evidence that crime perceptions respond to this change in content. After the Agreement, individuals with higher media exposure are less likely to report that they feel insecure and that their country, state, or municipality is insecure, relative to individuals with lower media exposure. Finally, I show that smaller changes on conspicuous consumption and food consumed outside the home accompany these changes in crime perceptions; while I do not find effects on stated crime avoidance behavior..
