    Sammanfattning : Paper [I] theoretically analyzes how the level and uncertainty of future prospects affect incentives to abstain from sexual risk taking in the presence of HIV. The results suggest that, for individuals with limited access to HIV treatment, uncertainty of future health may be an important factor driving unsafe sex practices and support the empirical finding of a weak link between sexual behavior, HIV prevalence, and HIV knowledge in poor countries; therefore suggesting that AIDS policy needs to be calibrated in order to fit within different social contexts.
