"Card's (1990) well-known analysis of the Mariel boatlift concluded that this mass influx of mostly less-skilled Cubans to Miami had little impact on the labor market outcomes of the city's less-skilled workers. This paper evaluates two explanations for this. First, consistent with an...

Is the Armed Forces Qualifying Test (AFQT) a measure of achievement or ability? The answer to this question is critical for drawing inferences from studies in which it is employed. In this paper, we test for a relationship between schooling and AFQT performance in the NLSY 79 by comparing...

During the past 15 years, however, arrivals from Mexico established sizeable immigrant communities in many "new" cities. We explore the causes and consequences of the widening geographic diffusion of...
