"Between 1976 and 1981 many pople moved out of Quebec, especially anglophones. To the extent that a person's decision to stay or to move may be related to earnings prospects, earnings comparisons with individuals who lived in Quebec in 1981 may suffer from a selection bias. This paper analyses emigration from Quebec and earnings with a two-equation model, using a sample of men drawn from the from the 1981 [Canadian] census. It is found that a selection bias is indeed present for anglophones and that the returns to learning French may be underestimated when that bias is ignored."
