Terrorism, Immigration and Asylum Approval

Using the universe of individual asylum cases in the United States from 2000-2004 and a difference-indifferences research design, we test whether Sept. 11, 2001 decreased the likelihood that applicants from Muslim-majority countries were granted asylum. Our estimates suggest that the attacks resulted in a 3.2 percentage point decrease in the likelihood that applicants from Muslim-majority countries are granted asylum. The estimated effect is larger for applicants who share a country of origin with the Sept. 11, 2001 attackers. These effects do not differ across judge political affiliation. Our findings provide evidence that emotions affect the decisions of judges.
