Cross-Border Media and Nationalism: Evidence from Serbian Radio in Croatia
研究显示，克罗地亚民众收听塞尔维亚广播后，对塞尔维亚族的敌意上升，表现为支持极端民族主义政党和出现更多仇恨涂鸦，实验证实了因果关系。
How do nationalistic media affect animosity between ethnic groups? We consider one of Europe's deadliest conflicts since WWII, the Serbo-Croatian conflict. We show that, after a decade of peace, cross-border nationalistic Serbian radio triggers ethnic hatred toward Serbs in Croatia. Mostly attracted by nonpolitical content, many Croats listen to Serbian public radio (intended for Serbs in Serbia) whenever signal is available. As a result, the vote for extreme nationalist parties is higher and ethnically offensive graffiti are more common in Croatian villages with Serbian radio reception. A laboratory experiment confirms that Serbian radio exposure causes anti-Serbian sentiment among Croats.
