In this paper, we use administrative records from the U.S. Border Patrol to examine how penalizing illegal border crossing affects recidivism in the apprehension of undocumented migrants at the U.S.-Mexico border. Over 2008 to 2012, the Border Patrol rolled out a Consequence Delivery System, which increased the fraction of apprehended border crossers subject to administrative or criminal sanctions from 15% to 85% percent. By matching finger prints across apprehension records, we detect if a migrant apprehended by the Border Patrol is subject to penalties and if he is re-apprehended at a later date. Exploiting day-to-day variation in the capacity of the Border Patrol to levy sanctions during the rollout phase, we estimate strong affects of penalties on the likelihood that an apprehended migrant re-attempts illegal entry and is recaptured. Exposure to (milder) administrative penalties reduces the 3-month and 18-month re-apprehension rates for male Mexican nationals by 6.6 and 4.6 percentage points, off of baseline rates of 22:6% and 24:2%; exposure to the full set of penalties reduces these re-apprehension rates by 8.1 and 6.1 percentage points. The estimated magnitudes imply that the rollout of the CDS can account for 28 to 44 percent of the reduction in re-apprehension rates over 2008 to 2012.
