Abstract

This contribution seeks to answer two questions, (1) What are the reasons for a demand for social health insurance (SHI)?, and (2) What are the limits to the growth of SHI? A review of the reasons for the existence of SHI reveals that while economists have emphasized the possible contribution of SHI to efficiency, the available evidence points to public choice reasons, which also seem to explain better the growth of SHI. Indeed, since private insurance redistributes as well (albeit governed by chance), it is tempting for politicians to use SHI for systematic redistribution (the extent of which cannot easily be detected by net payers). Turning to the supply of SHI, two dimensions are studied in some detail, viz. efforts at product innovation and at risk selection. Competing suppliers of SHI, while hampered by risk adjustment which sanctions innovators for attracting the young, are predicted to invest in innovation. A monopolistic public SHI scheme, by way of contrast, does not need to select risks and, on the other hand, it is predicted to refrain from product innovation. This is but one limit to the growth of SHI; the ultimate one is citizens’ lack of willingness to pay for its continuing expansion, about which some evidence for the case of Switzerland is presented.
