在这篇文章中，我们认为，工资不平等和职业流动性密切相关。我们的动机是我们的实证研究结果，人力资本是职业特异性的，在美国，工人转换职业的比例在20世纪70年代初高达16%，到20世纪90年代中期增加到21%。我们开发了一个一般均衡模型，职业特定的人力资本和异质性的经验水平的职业。我们发现，该模型，校准，以配合在20世纪70年代的职业流动性的水平，占相当不错的水平（组内）工资不平等在此期间。接下来，我们发现，该模型，校准，以配合职业流动性的增加，占超过90%的工资不平等的增加之间的1970年和1990年的。该理论也是定量一致的水平和增加的短期波动性的收益。
In this article we argue that wage inequality and occupational mobility are intimately related. We are motivated by our empirical findings that human capital is occupation specific and that the fraction of workers switching occupations in the U.S. was as high as 16% a year in the early 1970's and had increased to 21% by the mid-1990's. We develop a general equilibrium model with occupation-specific human capital and heterogeneous experience levels within occupations. We find that the model, calibrated to match the level of occupational mobility in the 1970's, accounts quite well for the level of (within-group) wage inequality in that period. Next, we find that the model, calibrated to match the increase in occupational mobility, accounts for over 90% of the increase in wage inequality between the 1970's and the 1990's. The theory is also quantitatively consistent with the level and increase in the short-term variability of earnings.
