Theoretical Foundations of Credential Signaling and Information Asymmetry
Signaling theory posits that educational credentials serve primarily as mechanisms to reduce information asymmetry between candidates and hiring organizations, offering observable indicators of underlying ability and productive capacity [1]. However, the proliferation of non-degree and modular certifications complicates this traditional dynamic. While comprehensive academic degrees convey established institutional reputations, micro-credentials represent granular competencies that often lack standardized vetting [2]. Consequently, hiring organizations face renewed information frictions when assessing whether short-cycle achievements reflect genuine technical proficiency or merely superficial engagement [4]. The signaling strength of alternative qualifications depends not only on individual skill acquisition, but critically on systemic visibility and the structural clarity of the issuing framework [2]. Without institutional consensus and rigorous alignment with industry requirements, modular certificates risk creating ambiguous signals that fail to yield meaningful labor-market advantages [1].
