In a CDDRL research seminar held on February 19, 2026, Oliver Kaplan, visiting scholar at CDDRL and Associate Professor at the University of Denver, presented a collaborative project on labor market discrimination against ex-combatants in Colombia. The study explores how prevalent hiring discrimination is against ex-combatants in the formal job market and whether this bias can be reduced. To highlight the significance of this issue, Kaplan emphasized the central role employment plays in reintegration, explaining that it is not only about income and individual well-being, but also about preventing recidivism, which is critical to long-term democratic stability and the rule of law. 

As Kaplan argues, stigma can play a major role in shaping hiring outcomes, as employers may associate ex-combatants with violence, instability, or unreliability, impacting the hiring process. Hence, the research tests whether ex-combatants face an employment penalty relative to non-ex-combatants. The study also examines whether conflict victims face similar bias and whether applicants who were both ex-combatants and victims experience different outcomes, since victim status could either reinforce stigma or generate sympathy and improve hiring chances. Finally, the study aims to identify practical ways to mitigate discrimination through education and skills training beyond high school, participation in reconciliation or peacebuilding activities, and the presence of employer tax incentives.

Kaplan and colleagues implemented a field experiment, partnering with Columbia’s reintegration agency to work with eight former combatants who applied to jobs using different versions of their resumes. The key treatment was selectively including or withholding information such as reintegration status, education, training, or reconciliation experience. This allowed the researchers to see how employers respond to different signals without faking information or using false identities. Applications were submitted through major online job platforms, and employer responses, including interview invitations, requests for additional information, and job offers, were tracked through calls, messages, and emails.  

Kaplan concluded by emphasizing the potential policy implications of these findings, explaining that improving access to employment through training and employer incentives might strengthen reintegration and reduce barriers faced by ex-combatants. Ultimately, Kaplan stressed that employment is not just an economic issue, but a key component of long-term peacebuilding, as access to stable jobs reduces the likelihood that ex-combatants return to conflict and helps sustain democratic stability.
