RETURNS TO COLLEGE MAJORS ACROSS LARGE METROPOLITAN AREAS
研究发现美国大都市地区不同大学专业的收入存在差异，主要源于集聚效应和空间需求差异，而个体选择的影响较小，尤其是对美国本土毕业生。
ABSTRACT In this paper, we provide new evidence that earnings for various college majors differ across large metropolitan areas in the United States. We then set out to explain, at least in part, why these differences exist. We find that the intrinsic elements of geographic areas, such as common agglomeration effects and spatial differences in demand, are an important explanation for all majors. Further, we find that the endogenous sorting of individuals plays less of a role, particularly for domestic‐born college graduates. The sorting of lower‐paid, foreign‐born college graduates, however, increases the estimated dispersion in returns across geographic areas.
