Missing Links: Referrer Behavior and Job Segregation
How does referral recruitment contribute to job segregation, and what can organizations do about it?
Current theory on network effects in the labor market emphasizes the job-seeker perspective, focusing on the
segregated nature of job-seekers’ information and contact networks, and leaves little role for organizational
influence. But employee referrals are necessarily initiated from within a firm by referrers. We argue that
referrer behavior is the missing link that can help organizations manage the segregating effects of referring.
Adopting the referrer’s perspective of the process, we develop a computational model which integrates a set
of empirically documented referrer behavior mechanisms gleaned from extant organizational case studies.
Using this model, we compare the segregating effects of referring when these behaviors are inactive to the
effects when the behaviors are active. We show that referrer behaviors substantially boost the segregating
effects of referring. This impact of referrer behavior presents an opportunity for organizations. Contrary to
popular wisdom, we show that organizational policies designed to influence referrer behaviors can mitigate
most if not all of the segregating effects of referring
Interactions and Mobility Edges: Observing the Generalized Aubry-Andre Model
Using synthetic lattices of laser-coupled atomic momentum modes, we experimentally realize a recently proposed family of nearest-neighbor tight-binding models having quasiperiodic site energy modulation that host an exact mobility edge protected by a duality symmetry. These one-dimensional tight-binding models can be viewed as a generalization of the well-known Aubry-Andre model, with an energy-dependent self-duality condition that constitutes an analytical mobility edge relation. By adiabatically preparing low and high energy eigenstates of this model system and performing microscopic measurements of their participation ratio, we track the evolution of the mobility edge as the energy-dependent density of states is modified by the model's tuning parameter. Our results show strong deviations from single-particle predictions, consistent with attractive interactions causing both enhanced localization of the lowest energy state due to self-trapping and inhibited localization of high energy states due to screening. This study paves the way for quantitative studies of interaction effects on self-duality induced mobility edges
