Returns to Seniority among Public School Teachers
发现公立学校教师资历回报占教育支出很大比例，前10-15年工资增长不低于白领，但人力资本等解释缺乏支持，认为薪酬结构更符合寻租而非高效合同。
Returns to seniority account for a substantial share of public K-12 expenditures. Over the first ten to 15 years of a career, public school teachers enjoy average wage growth at least equivalent to that of other white-collar workers. Explanations for this structure in terms of human capital or costly monitoring lack theoretical and empirical support. A steeper wage-tenure profile reduces turnover, but it is doubtful that the costs of turnover are high enough to make this an optimal use of school resources. We conclude that the structure of teacher pay in public education is more consistent with rent-seeking than efficient contracting.
