Emily Oster, the American economist, takes a look at AIDS. Roughly 25 million people in Africa are affected with AIDS and this is a disease of poverty. So, the widely popular belief is that the disease can be contained by curbing poverty. Uganda is the only African country successful in decreasing the prevalence of AIDS through an educational campaign. With the help of her extensive research, Emily challenges the all of the above.
In a place where there is a lot of AIDS, there is really significant cost of sex. So, people should have less sex in those areas. But this is not the case in Africa! Emily argues that people would have abstained from the costly act if there were enough benefits. But in Africa, the benefits are less because of short life expectancy.
