Most studies on the economic impact of HIV/AIDS focus on such variables as GDP growth or income per capita. Early studies, incorporating the impact of HIV/AIDS in a one-sector neoclassical growth model, found that although the impact of HIV/AIDS on GDP growth is substantial, the impact on GDP per capita may well be small. Later studies refined this approach, for example by considering a larger number of sectors, including some demand-side effects, or allowing for an impact of changes in life expectancy on individuals’ decisions.1
