The Impact of HIV/AIDS and ARV Treatment on Worker Absenteeism: Implications for African Firms
利用博茨瓦纳一家大型矿业公司的工人缺勤面板数据和艾滋病治疗项目信息，研究发现工人缺勤在治疗开始前后呈倒V形模式，治疗后1-4年缺勤率低且与未参加治疗的工人相当，且治疗收益可覆盖8-22%的成本。
We characterize medium and long-run labor market impacts of HIV/AIDS and ARV treatment using unique panel data of worker absenteeism and information from an AIDS treatment program at a large mining firm in Botswana. We present robust evidence of an inverse-V shaped pattern in worker absenteeism around the time of ARV treatment inception. Absenteeism one to four years after treatment start is low and similar to nonenrolled workers at the firm. Furthermore, our analysis suggests that for the typical manufacturing firm in Africa, the benefits of treatment to the firm cover 8-22 percent of the cost of treatment.
