本文提出了一个健康中机会不平等的行为模型，该模型将约翰·罗默的机会不平等框架与健康资本与健康需求的格罗斯曼模型相结合。该模型生成关于健康和生活方式的递归方程组，然后用具有自由相关误差项的全信息最大似然联合估计。该分析的创新之处在于解释了未观察到的异质性的存在，从而解决了部分情况问题，并将对机会不平等的审查扩大到自我评估的健康以外的健康结果，如长期疾病、残疾和精神健康。这些结果为同时影响健康结果和生活方式选择的第三因素的存在提供了证据，支持了部分情境问题的经验相关性。考虑到这些因素，本文证实了父母和早期环境对成人健康差距的影响是至关重要的。然而，影响每一项分析的健康结果的具体情况有很大不同。研究结果还表明，教育机会的差异和童年时期社会发展的差异是成年后生活方式的关键决定因素，而这反过来又塑造了观察到的健康不平等。版权所有(C)2010 John Wiley&Sons，Ltd.
This paper proposes a behavioural model of inequality of opportunity in health that integrates John Roemer's framework of inequality of opportunity with the Grossman model of health capital and demand for health. The model generates a recursive system of equations for health and lifestyles, which is then jointly estimated by full information maximum likelihood with freely correlated error terms. The analysis innovates by accounting for the presence of unobserved heterogeneity, therefore addressing the partial-circumstance problem, and by extending the examination of inequality of opportunity to health outcomes other than self-assessed health, such as long-standing illness, disability and mental health. The results provide evidence for the existence of third factors that Simultaneously influence health Outcomes and lifestyle choices, supporting the empirical relevance of the partial-circumstance problem. Accounting for these factors, the paper corroborates that the effect of parental and early circumstances on adult health disparities is paramount. However, the particular set of circumstances that affect each of the analysed health outcomes differs substantially. The results also show that differences in educational opportunities, and in social development in childhood, are crucial determinants of lifestyles in adulthood, which, in turn, shape the observed health inequalities.
