Selected Working Papers The Effect of Private Health Insurance on Medical Care Utilization and Self-Assessed Health in Germany joint with Patrick Hullegie HEDG Working Paper 09/17 In Germany, employees are generally obliged to participate in the public health insurance system, where coverage is universal, co-payments and deductables are moderate, and premia are based on income. However, they may buy private insurance instead if their income exceeds the compulsory insurance threshold. Here, premia are based on age and health, individuals may choose to what extent they are covered, and deductables and co-payments are common. In this paper we estimate the effect of private insurance coverage on the number of doctor visits and self-assessed health. Variation in income around the compulsory insurance threshold provides a natural experiment that we exploit to control for selection into private insurance. We document that income is measured with error and suggest an approach to take this into account. We find negative effects of private insurance coverage on the number of doctor visits and positive effects on health. Returns to Type or Tenure? joint with Roland A. Amann IZA Discussion Paper No. 2773 We analyze the joint determination of wage levels, wage growth and firm tenure. Our analysis is built on estimating a reduced form for tenure, a structural wage level equation and a structural wage growth equation. We disentangle returns to a latent type variable from estimates of general returns to tenure and wage gains from job changes. This type is related to unobservable match quality that is allowed to vary over time and to be correlated with the returns to tenure. The obtained results for Germany indicate that the type plays a crucial role in the remuneration of employees. Those types who change jobs more often obtain steeper wage profiles but earn less on average. (See also http://ideas.repec.org/e/pkl28.html and my vita for work in progress.)
