PuHI redistributes with respect to risk and income, and the market is affected by adverse selection. We argue that making PuHI voluntary does not lead to its collapse since individuals always participate in it. Additionally, in some cases, a voluntary PuHI scheme increases market efficiency because participation in it sends a signal to private insurers of an individual's health-risk type. The welfare consequences depend on the status quo. If in the status quo no political support exists for a compulsory PuHI, making it voluntary constitutes a Pareto improvement, and in some cases all individuals are strictly better off. If, instead, the status quo implements compulsory PuHI, making it voluntary then results in less redistribution.
