The interpersonal redistribution of resources is often brought about by compulsory participation or by public financing of social benefits. For example, a health insurance programme that requires all covered workers to make contributions to the benefit plan regardless of their health status. The redistributive nature of a social programme is most evident when support is provided for free or at sharply reduced prices, e.g. subsidised food programmes or free medical aid, but also the provision of income support under minimum living standard schemes in China, Japan or Korea.
