Social networks and spread of immigration attitudes
研究利用美联社禁用“非法移民”一词带来的态度变化，发现通过Facebook社交联系，受影响地区的移民态度改善会传播到其他地区，对政治传播和移民政策研究者有参考价值。
Abstract This study investigates how changes in immigration attitudes in an area spread to other localities. We use the exogenous variation in immigration attitudes from the Associated Press news wire service ban on the term “illegal immigrant,” which previous research has shown made immigration attitudes less hostile in more affected United States counties. We show that respondents in areas more socially connected (via Facebook) to those more affected by the ban exhibited improved immigration attitudes. Additional results suggest the likely channel is changing attitudes in socially connected counties and that people who use social media for political information are more affected.
