Borjas Challenges Card's Mariel Boatlift Study

  • George Borjas, a Harvard professor, decided to revisit David Card's Mariel boatlift study in 2015.
  • Borjas focused specifically on high school dropouts, a group Card had not isolated in his analysis.
  • His findings contradicted Card's, showing a significant 10-30% wage drop for high school dropouts in Miami.
  • Borjas's study suggested that the influx of immigrants did negatively impact the wages of the lowest-skilled workers.
  • This research overturned Card's pro-immigration findings and sparked controversy both within and outside the field of economics.
