Public service motivation and public sector employment in Korea

This study aims to investigate whether individual differences in public service motivation (PSM) between the public and private sectors are a cause or a consequence of choosing a job, testing self-selection and socialization hypotheses using a longitudinal dataset from a nationally representative cohort in Korea. The study uses two samples from the data of three successive waves (t − 2, t, t + 2) surveyed biennially, finding that “self-selection” can more persuasively explain the state that employees in the public sector have higher levels of PSM than those in the private sector, with job seekers with high PSM levels being more likely to work in the public sector and with the magnitude of differences in PSM between the public and private sectors maintained through the early years after entry into the workplace, while the levels of PSM, however, decrease in all job sectors. Implications of our findings are discussed.
