Health insurance can have important effects on self-employment and self- employment transitions. However, there is a literature gap on the relationship between health insurance and self-employment in low and middle income countries, especially in the context of rapid expansion of health insurance in these countries. This paper examines this relationship in Vietnam with a focus on the comparison between the voluntary scheme for the informal sector (mostly self-employed workers) and the compulsory insurance for the formal sector (mostly wage workers). We employ a Probit model with selection on a panel from the Vietnamese Household Living Standards Surveys 2010-2014 to investigate the association between health insurance and self-employment entry and exit. We show that those with compulsory health insurance in Vietnam, the formal workers, are 10 percentage points less likely to enter self-employment compared to those having voluntary insurance. Regarding self-employment exit, people with compulsory insurance are more likely to exit self-employment compared to those covered by voluntary insurance. However, the effect size is relatively small.

越南的健康保险和自雇过渡

健康保险可以对自营职业和自营职业过渡产生重要影响。但是，在中低收入国家，尤其是在这些国家的健康保险迅速扩大的背景下，关于健康保险与自雇职业之间关系的文献差距很大。本文考察了越南的这种关系，重点是对非正规部门的自愿性计划（主要是自雇工人）和正规部门的强制性保险（主要是工资工人）进行比较。我们采用Probit模型，并在2010-2014年越南家庭生活水平调查中的面板上进行选择，以调查健康保险与自雇出入境之间的关联。我们显示，在越南拥有强制性健康保险的人，正式工人，与拥有自愿保险的人相比，自雇的可能性要低10个百分点。关于自雇退出，与自愿保险覆盖的人相比，有强制保险的人更有可能退出自雇。但是，效果大小相对较小。
