From basic service delivery to child-sensitive product development to responsible business practice, the role of the private sector in achieving results for children is undeniable. Innovative public-private partnerships, corporate data-sharing and private-sector led technological innovations demonstrate how markets are shaping the future and the prospects for further development progress. How can the power of business and markets be harnessed for child well-being? We explore new models of private sector engagement and emerging business models for service delivery to identify how markets can be leveraged for children. We examine the potential for market-making and market-shaping in the provision of child-related goods and services, and the role of regulation where business practices pose a threat to child rights. Looking ahead, we analyse how to incentivize research and development for new solutions to address the needs of children.
