© 2018 John Wiley & Sons Ltd While the foundational claim that PSM attracts individuals to the public sector is well established in the research literature, much uncertainty still exists about its influence on the choice between the public versus the nonprofit sector, which also frequently exhibits a strong public service mission. Little is known also about how discrete dimensions of PSM differ in their effects on such job preferences. This article addresses these shortcomings by drawing on a study that combines the measurement of separate dimensions of PSM with a policy-capturing design that allows disentangling the effects of sector from those of other job attributes that usually correlate with it: the service orientation of the job and job security. Results show that dimensions of PSM display relevant differences in their effects on preferences across job attributes. These findings have important implications for the choice of PSM measurements in scholarly research and job selection.
