title: The seasonality of apprehensions of undocumented Mexican workers.
abstract: "This article uses within-year apprehensions data to test the economic determinants of Mexican undocumented immigration to the United States.  These data are highly seasonal and within-year border patrol apprehensions suggest that this seasonality is not solely due to changes in border patrol enforcement."  It is found that both supply and demand variables affect apprehensions and that agricultural factors appear to be important determinants of the variations in apprehensions.  The results are similar to those of earlier studies
