The researchers of this study examine the effects of a large refugee influx into Florida public schools following the Haitian earthquake of 2010 using unique matched birth and schooling records. They find precise zero estimated effects of refugees on the educational outcomes of incumbent students in the year of the earthquake or in the two years that follow, regardless of the socioeconomic status, grade level, ethnicity, or birthplace of incumbent students.
