摘要:As the Australian National Disability Insurance Scheme (NDIS) progresses through its implementation, calls for stewardship of the new disability market increase. As a personalisation scheme, the condition of the disability service markets are tied to the ability for people with disability to access care services. Market conditions such as thin markets, market gaps and market failure threaten the public policy goals of increased choice and control for NDIS participants. We review the evidence for interventions and other market stewardship actions that can be taken by government to steward a quasi-market that provides care or welfare services. We assess the breadth and quality of the evidence base and apply these findings to the case of the Australian NDIS. We conclude that there is sufficient evidence to take actions to steward the NDIS market, but that considerable resources and governance capacity are needed to do so.
