In this paper we focus on the implications of consumer heterogeneity for whether competition will improve outcomes in health care markets. We show that competition generally favours the majority group as higher quality for the majority is an effective way to increase the quality signal and...

Studies using education policy reforms to isolate causal effects of education on health produce mixed evidence. We analyse an unusually large sample and study chronic health conditions. For identification, we use two major education reforms, one that raised the minimum school leaving age and one...

Asthma is the most common chronic disease of childhood. Recent evidence has shown a socio-economic gradient in its distribution. This paper examines whether a number of factors argued to have led to a rise in the incidence of asthma might also explain the social gradient. Several of these have...

The use of genetic markers as instrumental variables (IV) is receiving increasing attention from epidemiologists, economists, statisticians and social scientists. This paper examines the conditions that need to be met for genetic variants to be used as instruments. Although these have been...

There is a growing literature that shows that higher family income is associated with better health for children. Wealthier parents may have more advantaged children because they have more income to buy health care or because parental wealth is associated with beneficial behaviours or because...
