Network-Mediated Labor Market Inequality Perpetuation
RCTClinical Trial
Relying on informal employee referral networks to fill job openings reduces employer search costs but systematically perpetuates long-run labor market inequality across demographic and socioeconomic groups.
Picture this
Think of job referral networks like a closed social club where members only invite people who look, live, and socialize like them. If the club members are predominantly from one wealthy group, job opportunities stay locked within that group, preventing qualified outsiders from accessing good jobs regardless of talent.
What the evidence says
45 percent of casual labor market participants in urban Kolkata found jobs through social connections, demonstrating that informal network reliance concentrates employment access within existing social circles unless counterbalanced by employer screening incentives.
- Who was studied
- N = 561 male labor market participants in urban Kolkata, India.
- How
- Micro-survey baseline analysis of urban labor market participants combined with formal social network search friction modeling.
What to do
Implement structured, merit-indexed referral bonuses or supplemental formal hiring channels to counter homophily and prevent referral reliance from reinforcing demographic hiring disparities.
