\item The outcome, log hourly wage, is residualized and multiplied by 100. All models include Year FE and Unit FE. Panel A includes Colombian-born migrants in the migrant share, while Panel B excludes them.  Column 2-4 use different share components of the shift-share IV, based respectively on the complete 2005 census (as in the main analysis), the 10\% subsample of the 1993 census, and the inverse minimum driving distance from the metro area or department capital to the closest Venezuelan border crossing. Geographic units include the 79 commuting zone-defined metro areas (as in the main analysis), the 23 official metro areas of which the GEIH is representative, and the 24 departments of Colombia. Observations weighted by unit-year population. Cluster-robust standard errors in parentheses. * p$<$0.10, ** p$<$0.05, *** p$<$0.01.
