The Effect of Salaries and Opportunity Costs on Duration in Teaching: Evidence from Michigan
利用密歇根州7800名公立学校教师的职业数据，发现薪资和机会成本显著影响教师留任时长，并指出当前教师供需模型的预测可能不准确。
This paper demonstrates that salaries and opportunity costs have important influences on how long teachers stay in teaching. The empirical work is based on a new longitudinal dataset providing information on the careers of 7800 Michigan public school teachers. The generalized least squares estimation technique accommodates censored observations, time-varying covariates, and fixed effects. One implication of the result is that predictions from the current generation of teacher supply and demand models are likely to be misleading. Copyright 1989 by MIT Press.
