The research on the so-called "Mariel boatlift" in the 80's was done back in 1990 and has since been disputed: > Most recently this has centred on a dispute between two economists, David Card at the University of California, Berkeley, and George Borjas, at Harvard University, over the effect of an unexpected surge in Cuban migrants to Miami in 1980 (the so-called “Mariel boatlift”). In 1990 Mr Card found this influx had no effect on the wages of low-skilled workers in Miami; Mr Borjas has now revisited the analysis, and claims that wages of high-school dropouts in fact fell substantially.
