Assessing the economic impact of HIV/AIDS on Nigerian households

In this paper,  Canning, Mahal, Odumosu and Okonkwo (2006) use propensity score matching to assess the affect of HIV/AIDS on an individual's ability to access health care in Nigeria.

The study  “compare[s] HIV positive people with a control group with similar observed characteristics, using propensity score matching. The matched control group has very different health and economic outcomes than a random sample of the population indicating that our HIV sample would not have had "average" outcomes even if they had not acquired HIV." (Canning, Mahal, Odumosu and Okonkwo 2006)
