Monopsony, Mobility, and Sex Differences in Pay: Missouri School Teachers
研究了密苏里州公立学校教师薪酬的性别差异，发现即使薪酬由经验与学历决定，女教师仍比男教师挣得少，部分源于流动性差异，但学区内的薪酬差异是更主要的原因。
We examine the sex differences in the pay of school teachers in Missouri. In Missouri school districts, pay is determined by a salary schedule that maps teaching experience and education level of an individual to a salary level. In spite of this apparently mechanical rule for determining pay, female teachers earn less than male teachers, after controlling for experience and education. We explore how such a difference could arise from differential job mobility and find some evidence to support this idea. However, within district differences in pay are a more important source of differences in pay between men and women.
