Item Effects of violent media content: Evidence from the rise of the UFC(Elsevier BV, 2022-05) Lindo, Jason, M.; Swensen, Isaac D.; Waddell, Glen R.We document the effect of violent media on crime. Specifically, we evaluate the effects of The Ultimate Fighter, a hit TV show that features fighters competing in violent mixed martial arts and which brought Ultimate Fighting Championship into the mainstream. We estimate the effect of exposure to the show’s earliest episodes using panel data from police agencies across the United States and a strategy that uses network ratings prior to the show’s premier as an instrumental variable. We show that this exposure significantly reduced crime: these effects are particularly evident for assault, began in the month the show premiered, and persisted for many years. These estimates do not reflect systematic differences across geographic areas in their trends in crime rates prior to 2005. To complement our main results, we also investigate the effects of “UFC Main Events,” which air in bars and on Pay-Per-View. This analysis additionally suggests reductions in violence caused by viewership.Item The Effect of Concealed-Carry and Handgun Restrictions on Gun-Related Deaths: Evidence from the Sullivan Act of 1911(Oxford University Press, 2022-01) Depew, Briggs; Swensen, Isaac D.The 1911 New York State Sullivan Act outlawed carrying concealable firearms without a licence, established strict licencing rules and regulated the sale and possession of handguns. We analyse the effects of the Sullivan Act using historical data on mortality rates, pistol permits and citations for illegal carrying. Our analysis of pistol permits and citations reveal clear initial effects of the Sullivan Act on gun-related behaviours. Using synthetic control and difference-in-differences methodologies, our main analyses show no effects on overall homicide rates, evidence of a reduction in overall suicide rates and strong evidence of a large and sustained decrease in gun-related suicide rates.Item Seasonal agricultural activity and crime(Wiley, 2021-09) Charlton, Diane; James, Alexander; Smith, BrockSudden shocks to labor demand have sometimes been shown to increase local crime rates. We build on this literature by estimating the causal effect of labor-intensive seasonal agricultural activity on crime. We analyze a unique data set that describes criminal activity and fruit, vegetable, and horticultural (FVH) employment by month and U.S. county from 1990 to 2016. We find that the FVH labor share is associated with reduced property and violent crime rates, and possibly the number of property crimes committed within county years. Examining heterogeneities based on ethnicity, labor-intensive FVH activity decreases the rate of non-Hispanic arrests and victimization, and increases the number of Hispanic arrests and victims (consistent with rising local Hispanic populations). Taken together, results are broadly consistent with the idea that agricultural harvest of labor-intensive crops enhances local labor market opportunities that reduce incentives to commit crimes. Results are robust to a battery of alternative specifications that address the inherent challenges associated with measuring seasonal agricultural labor.Item Seasonal agricultural activity and crime(Wiley, 2021-09) Charlton, Diane; James, Alexander; Smith, BrockSudden shocks to labor demand have sometimes been shown to increase local crime rates.
