The PhD work tries to support humanitarian aid for vulnerable migrants through both Operations Management and Migration fields. For example, with ZOA, we work on how to best implement aid for beneficiaries that are on the move (Venezuelan migrants in transit) by looking at how to maintain cash voucher programs where beneficiaries can cash-out and buy items across their entire route (route-based approach to cash voucher assistance). Together with ZOA’s pilot program in Colombia, we look at challenges in maintaining and selecting a large number of retailers involved as payment points in the program, and examine rapid, short-term increases in demand due to external shocks that drive up beneficiary numbers. However, migrants in transit are only a part of the story. Once migrants reach their destination, the assistance needs to be continued – NGOs have to be prepared and ready to receive these beneficiaries. With World Vision, we look at how individuals who migrate in response to shocks (eg: violence) choose their destinations. In this project, we also focus on the Venezuelan exodus. We work with World Vision in Colombia, Venezuela, and Brazil, to understand vulnerable migrants’ preference for choosing, for example, Brazil as a destination over Colombia, after experiencing a shock. Existing migration studies have focused on decision-making for labour migration, higher-education, and so on. Our contribution to this field is in examining how individuals make these decisions as a direct response to shocks, and to make recommendations on factors that NGOs can monitor in each country, in order to prepare for incoming migrants.
