As it has become increasingly recognized that inequalities in health stem more from inequalities in wealth, rather than from inequalities in access to medical care, economists have begun to suggest that Michael Grossman's model of the demand for health may be a useful analytical framework for investigating the issue. Ironically, the more popular of(More)
This paper provides an analysis of the effects of uncertainty on the demand for medical care using a simplified version of Grossman's human capital model of the demand for health. Two types of uncertainty are analysed: the uncertainty surrounding the incidence of illness and the uncertainty surrounding the effectiveness of medical care. In the first the(More)
The aim of this paper is to test for stochastic monotonicity in intergenerational socio-economic mobility tables. In other words we question whether having a parent from a high socio-economic status is never worse than having one with a lower status. Using existing inferential procedures for testing unconditional stochastic monotonicity, we first test a set(More)
Is there a trade-o between people's preference for income equality and income mobility? Testing for the existence of such a trade-o is di cult because mobility is a multifaceted concept. We analyse results from a questionnaire experiment based on simple precise concepts of income inequality and income mobility. We nd no direct trade-o in preference between(More)
In chronic hepatitis C, transient elastography (TE) accurately identifies cirrhosis, but its ability to assess significant fibrosis (Metavir > or = F2) is variable. Constitutional and liver disease-related factors may influence TE and here we examined the variables associated with differences. Three hundred consecutive hepatitis C virus (HCV)-RNA positive(More)
This paper identifies two distinct types of payoff kinks that can be exhibited by preference functions over monetary lotteries—“locally separable” vs. “locally nonseparable”—and illustrates their relationship to the payoff and probability derivatives of such functions. Expected utility and Fréchet differentiable preference functions are found to be(More)
The Medicare program, which provides insurance coverage to the elderly in the United States, does not protect them fully against high out-of-pocket costs. For this reason private supplementary insurance, named Medigap, has been available to cover Medicare gaps. This paper studies how Medigap affects the utilization of inpatient care, separating the(More)
