Research Questions
As this dissertation project is cumulative in nature, the three constituting research papers pursue multiple yet closely interrelated research questions and goals. The first paper, written in co-authorship with Prof. Adrian Ritz, is the first quantitative-systematic literature review on Public Service Motivation, a concept which has seen rapid growth in theoretical and empirical publications in recent years. As such, the goal of the first paper is to summarize and structure the body of literature on PSM, identifying key publications, theories and findings, thereby facilitating further research and the development of a more encompassing theoretical framework.
The second paper builds upon a key research gap identified in the first paper, asking and analyzing the question whether PSM can be understood as an integral part of the more general, sector-unspecific intrinsic-extrinsic motivation framework frequently used in behavioral economics research. To answer this research question, the paper draws upon the common assumption that individuals with high levels of PSM are attracted to public service jobs while individuals with low levels of PSM are attracted to other kinds of jobs, depending on their individual motivational preferences. Based on person-environment fit theory, the author develops a spatial rational-choice model comprising three general dimensions of motivation: “extrinsic motivation”, “enjoyment-based intrinsic motivation” and “obligation-based intrinsic motivation”. Within the model, PSM is conceptualized as a set of combinations of relatively high values on the obligation-based intrinsic dimension, and relatively low values on the enjoyment-based intrinsic and extrinsic dimensions. By mapping individuals based on their motivational preferences (denoted “P” in the illustration), and specific jobs based on their advertised motivational incentive structure (denoted “Ei”) into the model, it is possible to predict mutual attractiveness (“fit”) by calculating the spatial distance between the two. An experimental research design is proposed and will be carried out to test the model.
