Evaluating the Impact of Health Programmes
"This paper has two broad objectives. The first objective is broadly methodological and deals with some of the more pertinent estimation issues one should be aware of when studying the impact of health status on economic outcomes. We discuss some alternatives for constructing counter-factuals when designing health program evaluations such as randomization, matching and instrumental variables. Our second objective is to present a review of the existing evidence on the impact of health interventions on individual welfare."
