Gender gaps in labor market outcomes persist in South Asia. An open question is whether supply- or demand-side constraints play a larger role. This paper investigates this using matched data from three sources in Lahore, Pakistan: representative samples of jobseekers and employers, administrative data from a job matching platform, and an incentivized binary choice experiment. Employers’ gender restrictions are a larger constraint on women’s job opportunities than supply-side decisions. This demand-side gap in the quantity of job opportunities closes as education levels increase and jobs become more “white-collar.”
