Transactional Sex as a Response to Risk in Western Kenya
利用192份自我报告日记构成的独特面板数据，研究发现肯尼亚西部女性在遭遇意外健康冲击（尤其是家庭成员生病）时，会显著增加高风险、高报酬的交易性行为供给，表明她们缺乏其他消费平滑机制来应对风险。
Though formal and informal sex work has long been identified as crucial for the spread of HIV/AIDS, the nature of the sex-for-money market remains poorly understood. Using a unique panel dataset constructed from 192 self-reported diaries, we find that women who engage in transactional sex substantially increase their supply of risky, better compensated sex to cope with unexpected health shocks, particularly the illness of another household member. These behavioral responses entail significant health risks for these women and their partners, and suggest that these women are unable to cope with risk through other consumption smoothing mechanisms.
