We evaluate the effect of the size of deductibles in the basic health insurance in Switzerland on the probability of a doctor visit. We employ nonparametric bounding techniques to minimise statistical assumptions. In order to tighten the bounds we consider three further assumptions: mean independence of an instrument, monotone treatment...

This paper presents new evidence on income-related health inequality and its development over time in Switzerland. We employ the methods lined out in van Doorslaer and Jones (2003) and van Doorslaer and Koolman (2004) measuring health using an interval regression approach to compute concentration indices and decomposing inequality into its...

This study investigates equity in access to health care in Switzerland over time, using nationwide representative survey data from 1982, 1992, 1997 and 2002. Both simple quintile distributions and concentration indices are used to assess horizontal equity, i.e. the extent to which adults in equal need for medical care appear...

revised version published in: Health Economics, 2005, 14 (10), 999-1018

Using longitudinal data from the Canadian National Population Health Survey (NPHS), we study the relationship between health and employment among older Canadians. We focus on two issues: (1) the possible endogeneity of self-reported health, particularly "justification bias", and (2) the relative importance of health changes and long-term health in the...
