The study aims to provide a thorough economic and financial analysis of the design, feasibility, governance and implementation options of a possible future Child Guarantee Scheme in all EU Member States. To achieve this, it has prepared a detailed comprehensive study exploring what would be the most cost-effective strategy for the competent authorities to realise a child guarantee for all children at risk of poverty in the EU. The study complements the Study on the feasibility of a child guarantee for vulnerable children: Phase I.
