The Salaries of Ph.D.'s in Academe and Elsewhere
研究了博士在学术界与其他雇主（如政府和行业）之间的薪资差异，并探讨这种差异是否反映员工质量差异或补偿性差异（如学术自由和工作保障）。
It has long been known that Ph.D.'s working for academic institutions earn less than Ph.D.'s in the same disciplines working for other kinds of employers, especially government and industry. It has not been possible to tell, however, whether this difference in earnings represents a difference in average quality of the employees in the two sectors or whether it represents a compensating differential reflecting the greater autonomy and freedom from control of superiors in the academic sector and the greater job security of tenured professors. It is now possible to answer this question through the use of special tabulations of data from the Survey of Doctoral Recipients of the National Research Council (1989).
