The need for jobs support in economies affected by forced displacement and conflict is high, with forced displacement at its highest level since the Second World War and poverty expected to be increasingly concentrated in economies affected by fragility, conflict, and violence (FCV). Developing impactful and cost-effective jobs support requires good data on program costs and benefits, but such information remains notoriously scarce in FCV and displacement situations. This study presents insights from a new dataset of cost and results in the jobs support project portfolios of Foreign, Commonwealth and Development Office (FCDO), United Nations High Commissioner for Refugees (UNHCR), and the World Bank in six low- and middle-income economies affected by conflict and displacement. It analyzes results on the cost-efficiency of jobs support to inform design and budget planning, as well as results on cost effectiveness, with a view to informing choice between different modalities while taking into account additionality and sustainability of outcomes achieved.
