The viability, quality and sustainability of publicly supported early childhood education and care services is a lively issue in many countries, especially since the rights of the child imply equal access to provision for all young children. But equitable provision within childcare markets is highly problematic, as parents pay for what they can afford and parental income inequalities persist or widen. This highly topical book presents recent, significant research from eight nations where childcare markets are the norm. It also includes research about 'raw' and 'emerging' childcare markets operating with a minimum of government intervention, mostly in low income countries or post transition economies. Childcare markets compares these childcare marketisation and regulatory processes across the political and economic systems in which they are embedded. Contributions from economists, childcare policy specialists and educationalists address the question of what constraints need to be in place if childcare markets are to deliver an equitable service.
