The role of self-interest and ideological beliefs for supporting a ‘solidaristic’ health policy in Norway

• The lowest educated and of poor health have higher spending willingness on public healthcare. • The old, unhealthy and worse-off oppose higher co-payments for “self-inflicted” diseases. • Liberal-conservative voters prefer less public spending, more co-payments and easier uptake of health insurance. Previous studies of health system legitimacy have almost exclusively paid attention to patterns of service satisfaction and preference for state involvement. These two dimensions are related to substantial and procedural justice; i.e. the value of a certain policy and the way it is implemented. This study contributes to the research field by focusing on a third dimension that have been little studied so far: the willingness of citizens to contribute on a solidaristic basis. This dimension was captured through three health policy preferences: public healthcare spending willingness, opposition to co-payments and opposition to private health insurance. Building on the literature on welfare state legitimacy, the empirical model distinguished between two sets of predictors to explain individual differences: self-interest and ideological belief. Old age, poor health and poor economy is positively associated with opposition to co-payments for “self-inflicted” diseases, while low education and poor health is positively related to support for more public spending. Increasing age is furthermore positively associated with opposing co-payments and easier uptake of insurance. Liberal-conservative voters are less willing to spend more on healthcare but more willing to increase the use of co-payments and insurance.
