This study expands our knowledge about public service motivation in the context of politics as a concept defined by self-interested and other-interested motives. Current research shows the importance of other-interested public interest as a person-environment fit variable. We test the assumption that self-interested motives differ in regard to behavioural outcomes of local councillors when compared to other-interested motives. Using a dataset of 8,111 local government councillors in Switzerland, our analysis reveals that self-and other-interested motives have different behavioural outcomes, and that the rational motive of attraction to policy-making acts solely as a moderator between resistance within council and seeking re-election. The utility of these findings for the further development of theory on public service motivation and implications for future research are also discussed.
INTRODUCTIONIn the course of the past two decades, a new research stream has evolved to investigate public employees' motivational structure: Public Service Motivation (PSM). More than 200 publications deal with questions regarding the antecedents of PSM, such as value preferences (e.g. monetary incentives), and outcomes, such as occupational intentions or individual performance of public employees (Ritz et al. 2013). The majority of these publications in general treat PSM as an important characteristic of public employees. However, with the exception of one recent study (Pedersen 2014), no publication investigates the PSM-related motives of political executives -yet these individuals are the leaders of public organizations and their motivation is crucial for good public service.Research on politicians' motivation and its implications for behavioural outcomes is scarce. Nevertheless, we identify two lines of argumentation. First, classical theory states that politicians are driven primarily by self-interest -we all know examples of politicians who have abused their position for personal gain or whose manoeuvres are purely opportunistic, with the next election in mind. Second, individuals have mixed motives (Bolino 1999), meaning that besides self-interest, it is likely that other-interested motives such as, for instance, community interests play a major role in politicians' behaviour. In the literature on political recruitment we find empirical evidence for various motives guiding politicians. According to this literature, civic duty motives and the motive to help others are important facets of politicians' personality influenced by institutional socialization, which reaches far wider than political socialization does (Verhelst et al. 2013).Using those two major lines of argumentation we integrate the literature on PSM which investigates the motivational characteristics of public actors from a value perspective developed by socialization within society and public organizations (Perry and Wise 1990; Vandenabeele 2007). Most of this work is related to the motivation of ordinary public employees, and only a few authors include perspect...
