July 2020Immigration and Violent Crime: Evidence from the Colombia-Venezuela Border
with Brian G. Knight: w27620
This paper investigates the link between violent crime and immigration using data from Colombian municipalities during the recent episode of immigration from Venezuela. The key finding is that, following the closing and then re-opening of the border in 2016, which precipitated a massive immigration wave, homicides in Colombia increased in areas close to the border with Venezuela. Using information on the nationality of the victim, we find that this increase was driven by homicides involving Venezuelan victims, with no evidence of a statistically significant increase in homicides in which Colombians were victimized. Thus, in contrast to xenophobic fears that migrants might victimize natives, it was migrants, rather than natives, who faced risks associated with immigration. Using arrests dat...
June 2019Opposition Media, State Censorship, and Political Accountability: Evidence from Chavez's Venezuela
with Brian Knight: w25916
This paper investigates the effects of state censorship of opposition media using evidence from the closing of RCTV, a popular opposition television channel in Venezuela. The government did not renew RCTV’s license, and the channel was replaced overnight, during May 2007, by a pro-government channel. Based upon this censorship of opposition television, we have three key findings. First, using Nielsen ratings data, viewership fell, following the closing of RCTV, on the pro-government replacement, but rose on Globovision, the only remaining television channel for opposition viewers. This finding is consistent with a model in which viewers have a preference for opposition television and substitute accordingly. Second, exploiting the geographic location of the Globovision broadcast towers, Cha...
March 2016The Limits of Propaganda: Evidence from Chavez's Venezuela
with Brian Knight: w22055
In this paper, we investigate viewer responses to changes in the ideological content of television programming using variation induced by cadenas, unannounced takeovers of the public television airwaves by the government in Venezuela. Using high-frequency ratings data, we find that, consistent with the predictions of our choice model, the drop-off in ratings during cadenas is concentrated among viewers of news programming on opposition private channels, as opposed to viewers of news on pro-government public channels. Also consistent with the predictions of our model, the drop-off in ratings for private channels with moderate ideology takes an intermediate value. In addition, the drop-off is stronger for viewers with access to cable channels, which are not required to air cadenas. Consisten...
