Abstract
Three secondary data sources are used to answer four questions that relate to the theory of public-service motivation. The questions focus on the incidence of public-service reward motivations, consistency of these motivations over time, their impact on organizational performance, and the ramifications of a public-service ethic for the theory of representative bureaucracy. Using descriptive and multivariate statistics, the analyses conclude that there are generalizable and stable differences in the reward motivations of public- and private-sector employees. There is also evidence that public-service motivation in the federal sector is positively related to organizational commitment. In contrast, there is no evidence that public-policy attitudes vary between those who are and those who are not public service oriented.
