ABSTRACT
The President's Emergency Plan for AIDS Relief (PEPFAR) is the United States government's global strategy to fight the human immunodeficiency virus and acquired immune deficiency (HIV/AIDS) pandemic. The first DID (Difference-in-Differences) model assesses PEPFAR's ABC by using the incidence of adult HIV as the dependent variable. The chapter provides changes in the total fertility rate are used as an additional way of evaluating the effectiveness of PEPFAR's ABC programs. The micro-economic models of fertility draw from the neoclassical theory underlying consumer behavior. Multicollinearity is said to exist when two or more independent variables are "highly" correlated. The variance inflation factor (VIF) is a common statistic used in multicolline-arity analysis. The fall in adult HIV rates in sub-Saharan Africa is a welcome development. This reduction in HIV incidence likely reflects the natural trends in the epidemic as well as the result of prevention programs resulting in behavioral change in different contexts.
