摘要

我们研究了在受监管的健康保险市场中提供覆盖水平选择（“垂直选择”）的福利效应。我们强调，有效覆盖水平的异质性不足以激励选择。当保费不能反映个人成本时，选择他们的有效保险水平可能不符合消费者的最佳利益。我们表明，只有具有更高支付意愿的消费者具有更高的有效覆盖水平，垂直选择才是有效的。我们实证研究了这种情况，发现只要可以强制执行最低覆盖水平，垂直选择带来的福利收益要么为零，要么在经济上很小。

When Should There Be Vertical Choice in Health Insurance Markets?

We study the welfare effects of offering choice over coverage levels-"vertical choice"-in regulated health insurance markets. We emphasize that heterogeneity in efficient coverage level is not sufficient to motivate choice. When premiums cannot reflect individuals' costs, it may not be in consumers' best interest to select their efficient coverage level. We show that vertical choice is efficient only if consumers with higher willingness-to-pay have a higher efficient level of coverage. We investigate this condition empirically and find that as long as a minimum coverage level can be enforced, the welfare gains from vertical choice are either zero or economically small.
