| Outline of Final Research Achievements |
Levirate marriage, whereby a widow is inherited by male relatives of her deceased husband, has anecdotally been viewed as an informal safety net for widows. This study investigates why this widespread practice in sub-Saharan Africa has recently been disappearing. As a developed game-theoretic analysis reveals, female empowerment renders this widespread practice redundant because it increases widows' reservation utility. HIV/AIDS also discourages a husband's clan from inheriting a widow who loses her husband to HIV/AIDS, reducing her remarriage prospects and thus, reservation utility because she is likely to be HIV positive. By exploiting long-term household panel data drawn from rural Tanzania and testing multiple theoretical predictions, this study finds that HIV/AIDS is primarily responsible for the deterioration of levirate marriage. Young widows in Africa may need some form of social protection against the influence of HIV/AIDS.
