The Labor‐Market Effects of Occupational Licensing Laws in Nursing
研究了美国各州在不同时间对注册护士和执业护士实施职业许可对工资和参与率的影响，发现许可使工资提高5%至10%，但未减少总体参与，且缩小了少数族裔与非少数族裔的工资差距。
We study the labor‐market impacts of occupational licensing laws on nursing, an economically important occupation. States adopted licensing of registered and practical nurses at different times, which allows us to estimate the effects of licensing on wages and participation for each nursing profession. We find that licensure raised wages by 5 to 10 percent but there is no evidence that it reduced overall participation. Additionally, we show that licensure equalizes wages within the occupation with minority wages rising faster than nonminority wages; however, licensing had a negative but not statistically significant impact on the participation of minorities in nursing.
