This article evaluates whether changes in relative earnings across majors due to a federal tax reform are likely to affect college major choice. I first estimate the change in expected after-tax lifetime income due to the 1986 Tax Reform Act for 47 majors. I find that the average major experienced an increase in expected after-tax lifetime income of 6.2 percent and that the standard deviation of major-specific expected lifetime income premia increased by 6.1 percent. I estimate the impact of the change in relative earnings on the distribution of completed college majors, finding no statistically significant change in the composition of majors following the reform. Consistent with the estimation, simulations reveal that at most 0.25 percent of males completed a different major in response to the reform.

本文的计算结果，由于联邦税收改革变化，跨专业的学生相对收益是否可能影响到大学的专业选择。我首先估计预期税后终身收入由于1986年税收改革法案47个大满贯的变化。我发现，平均主要经历了6.2％预期税后一生的收入增长和具体的重大预期的终身收入溢价的标准差增加了6.1％。我估计在完成科班出身的分布相对收益变化的影响，发现在专业采取改革的组成没有统计学显著变化。与估计一致，模拟显示，男性最多0.25个百分点完成不同的主响应改革。
