Public Administration Review

Public sector recruitment is an urgent and prevailing challenge in both research and practice. Public employer branding is an important subject in the theoretical debate , but the mechanisms behind how certain signals of public employers affect individuals' interest in a job are under‐researched. By bridging signaling theory , social identity theory , and personnel economics , this study analyzes the effects of signals in advertisements related to societal impact , job security , and performance orientation on different gender/age‐based target groups. This series of pre‐registered social media field experiments (n = 196 , 822 persons) with four public employers examines the degree to which these signals affect individuals' interest in a job at a public employer. The results do not show an overall impact of the signals but target group‐specific effects—gender has a significant effect and age for certain public employers. Compared with the societal impact signal , the job security signal has a slightly stronger effect.
