Title: Proximity and Prejudice: A field experiment on gig workers’ discrimination against homoesxual job posters
Dr David Smerdon is a Senior Lecturer (equivalent to Associate Professor) in the School of Economics of the University of Queensland. He primarily works in behavioral and development economics. His research involves theory and modelling, experiments in the lab and field, and microeconometric analysis in order to investigate topics at the intersection of these fields. David earned his PhD from the Tinbergen Institute and the University of Amsterdam (UvA) as a General Sir John Monash scholar, and afterwards worked as a PODER fellow at Bocconi University in Milan. His research often involves collaboration with non-academic partners, ranging from aid agencies and NGOs like US AID and Save the Children, to tech companies like Chess.com. He has published among others in Nature Human Behavior, PNAS, Experimental Economics and Perspectives in Psychological Science.

Title of the presentation: “Proximity and Prejudice: A field experiment on gig workers’ discrimination against gay job posters” (co-authored with Sabina Albrecht (University of Queensland) and Samuel Pearson (University of Queensland)
Abstract: We investigate the influence of physical proximity on sexual-orientation discrimination within the gig economy. Utilising a field experiment on a prominent gig-economy platform that connects local errand service demand with freelance workers, we posted 1,200 unique jobs across six Australian cities. These jobs were experimentally manipulated to appear as being posted by either a gay or straight male, while also randomising the job’s proximity to the poster (inside or outside the house). The results show no discrimination against gay job posters for tasks located outside the house. However, for indoor tasks requiring close proximity to the poster, workers discriminated against gay job posters by making fewer offers and by generally engaging less with job posts. Additionally, indoor jobs posted by gay individuals attracted lower-quality but similarly-experienced workers compared to those posted by straight individuals, indicating that the observed discrimination is taste-based rather than statistically driven. Our results contribute to the discrimination literature by highlighting the moderating role of physical proximity, with potential implications for the broader labour market as remote-work options become more common.
