Abstract: Currently, Japan is facing a rapid increase in its aging population and must take measures to
address the issue. Because of the aging population, the demand for medical services is
increasing. In order to respond to this increasing demand, an increase in the number of nurses
seems to be essential. Generally, when the demand for nurses exceeds the supply of nurses, the
wages offered to nurses must increase. In this paper, we firstly investigate whether the income of
professionals and engineers, including include nurses, is higher than that of other occupations.
Secondly, we analyze whether a nurse's income ranks high among those of professional workers
and engineers in Japan. In the estimation results using an ordered probit model, we found that
professional workers and engineers receive a high yearly income compared to other workers, but
we cannot reject the hypothesis that there is no income difference between nurses and other
professional workers and engineers.
