The rise and fall of customary wage differentials among nursing personnel in US hospitals: 1956–1985
研究了1956至1985年间美国医院中注册护士相对其他护理人员的就业上升，而相对工资却保持不变的现象，提出制度性解释替代传统的买方垄断模型。
Between 1956 and 1985, the employment of registered nurses (RNs) relative to other nursing personnel rose despite constant relative wages among RNs, licensed practical nurses, and nurses' aides. Over this thirty-year period, hospital management proclaimed chronic shortages of RNs. Economists have used monopsonistic models to explain the persistence of these shortages. As an alternative to the monopsonistic model, this paper presents an institutional argument for why hospital management sought to maintain relative wages among classes of nursing personnel while at the same time successfully raising the relative use of RNs through a variety of nonwage inducements and manipulations of RN supply.
