The impact of the AIDS epidemic on African nations through 2002 using the male circumcision rate to identify plausibly exogenous variation in HIV prevalence. Medical researchers have found significant evidence that male circumcision can reduce the risk of contracting HIV.

Do you think AIDS can be a macroeconomic deterant or catalyst?
