In the literature review of their article "The Links Between Education and Health," Ross and Wu (1995) clearly specify many specifications of independent variables and dependent variables because they review many empirical studies. On p. 722, the authors identify the dependent variable of physical health and the independent variable of employment status in a set of three studies that focus on women.
