Who's declining the “free lunch”? New evidence from the uptake of public child dental benefits
研究发现，澳大利亚针对弱势家庭儿童的公共牙科福利中，只有三分之一的家庭实际领取，认知偏差和行为因素（如母亲心理健康差、高风险生活方式）是主要障碍，信息缺乏也有影响。
This study provides the first evidence on the determinants of uptake of two recent public dental benefit programs for Australian children and adolescents from disadvantaged families. Using longitudinal data from a nationally representative survey linked to administrative data with accurate information on eligibility and uptake, we find that only a third of all eligible families actually claim their benefits. We provide new and robust evidence consistent with the idea advanced by recent economic literature that cognitive biases and behavioral factors are barriers to uptake. For instance, mothers with worse mental health or riskier lifestyles are much less likely to claim the available benefits for their children. These barriers to uptake are particularly large in magnitude: together, they reduce the uptake rate by up to 10 percentage points (or 36%). We also find some indicative evidence that a lack of information is a barrier to uptake.
