Abstract: We test for a "Ferguson Effect" by studying how police effort responds to different incidents of police violence. We do so using two settings in Minneapolis: (1) George Floyd's murder, and (2) police-involved shootings. We find that following George Floyd's death, arrests and police-initiated calls decreased by 62 and 69 percent, respectively. By comparison, arrests and police-initiated calls decreased by 3 and 1.5 percent following police-involved shootings. We conclude that incidents of police violence generate "de-policing," and the effect is much larger following highly publicized incidents.

Using a time regression discontinuity design, we estimate a 72.7 percent decrease in lower-level “quality of life” arrests
