When time is the numeraire in a social evaluation of public projects, life expectancies are essentially the unit of account. Since different generations have different life expectancies, pursuing intergenerational equity requires discounting the extra time that future generations are likely to...

There are many recent studies that indicate that female education and HIV are still positively related in sub-Saharan Africa (SSA). So education is not a vaccine as claimed and there exists a puzzle that needs to be resolved. In this study, by focusing on the use and non-use of condoms by...

This paper uses the revealed preference, willingness-to-pay approach to estimate the benefits in a cost-benefit analysis of a condom social marketing (CSM) program in Tanzania. The demand curve used to derive the consumer surplus had unit elasticity and it was estimated from a cross-section...

This paper provides a critique of techiniques for estimating distributional weights using the revealed preference (imputational) approach. Stochastic versus deterministic methods are contrasted and a preference for the stochastic methodology is indicated. It argues that Probit is the most...
