Premium subsidies have been advocated as an alternative to social health insurance. These subsidies are paid if expenditure on health insurance exceeds a given share of income. In this paper, we examine whether this approach is superior to social health insurance from a welfare perspective. We show that the results crucially depend on the correlation of(More)
This paper examines whether myopia (misperception of the long-term care (LTC) risk) and private insurance market loading costs can justify social LTC insurance and/or the subsidization of private insurance. We use a two-period model wherein individuals differ in three unobservable characteristics: level of productivity, survival probability and degree of(More)
Invoking Yaari's dual theory, we develop a model of individual vaccination decisions that incorporates quasi-hyperbolic discounting, risk aversion, and information. We test the resulting hypotheses for the flu season 2010/2011 using a representative German data set. We find a significant impact of time preferences on immunization decisions. The impact of(More)
Transfers within a Three Generations Family: When the Rotten Kids Turn into Altruistic Parents We study exchanges between three overlapping generations with non-dynastic altruism. The middleaged choose informal care provided to their parents and education expenditures for their children. The young enjoy their education, while the old may leave a bequest to(More)
An unhealthy good causes health issues in the long run. It creates a misperceived utility loss and increases health care costs. Conversely, a healthy good provides misperceived utility gains and reduces health care costs. Individuals differ in income and in their degree of misperception; they vote over a fat tax according to their misperceived utility. A(More)
United but (Un-)Equal: Human Capital, Probability of Divorce and the Marriage Contract * This paper studies how the risk of divorce affects the human capital decisions of a young couple. We consider a setting where complete specialization (one of the spouses uses up all the education resources) is optimal with no divorce risk. Symmetry in education (both(More)
We show that quasi-hyperbolic discounting not only affects savings but also the demand for long-term care insurance. In general, the demand of quasihyperbolic discounting individuals differs from the demand of exponential discounters. Furthermore, quasi-hyperbolic discounters’ insurance demand is time-inconsistent. In the presence of a binding liquidity(More)
