In the competitive marketplace of higher education, college and university alumni are increasingly called on to support their institutions in multiple ways: political advocacy, volunteerism, and charitable giving. Drawing on alumni survey data gathered from a large research extensive university, we employ a multinomial logistic regression model to distinguish characteristics of inactive alumni from those who give, volunteer, or give and volunteer at their alma mater. Economic, social exchange, expectancy, and investment theories shed light on lifecycles, attitudes, and lifestyles associated with alumni giving and voluntary support for higher education.
