Existing literature on the impacts of adult illness on household labour supply and income in low- and middle-income countries shows that adverse health conditions significantly affect household labour supply, work participation and earnings. Most of the studies, however, are not equipped to distinguish between short- and long-term consequences of adult illness. We measured the impact of adult illness on household employment outcomes both in the short- and the long-run, using a unique longitudinal data set from rural India.
We used two waves of India Human Development Survey (1993-94 and 2004-05) with a balanced panel of 10 726 households to assess short-run (in the year of the occurrence of adult illness) and long-run (after 11 years of the occurrence of adult illness) effects of major illness of adult household members aged 15-64 years on household employment outcomes, using multiple matching methods: nearest-neighbor matching and inverse probability weighting following propensity score matching, and coarsened exact matching to compare employment outcomes to a set of matched control households.
Rural households affected by adult illness experienced declines in workforce participation rate by 1-3%, wage employment by 4-15 days, and wage-earnings by Indian Rupee (INR) 374 to INR 837 compared to the matched control households in the short-run. In response, adult non-sick members of the affected households increased their workforce participation sharply by 14-16% to compensate for shortfalls in the short-run. In the long-run, workforce participation rate of the affected households also declined by nearly 1-3%. The long-run declines in wage-days and wage-earnings were small and not always statistically significant across the methods. However, long-run workforce participation rate of non-sick adults were smaller (4-6%) compared to short-run, but still statistically significant.
The long-term effects were smaller in absolute magnitude than those of the short-run. This suggests coping and adjustments by the affected households using this 11-year longer time-span in a manner that helps to ameliorate the immediate impacts of adult illness. Our study also reiterates the importance of improving financial access to health services as well as access to social security benefits for the illness-affected households in rural India both in the short- and long-run.
现有关于成年人疾病对中低收入国家家庭劳动力供应和收入影响的文献表明,不利的健康状况会显著影响家庭劳动力供应、工作参与和收入。然而,大多数研究都无法区分成年人疾病的短期和长期后果。我们使用来自印度农村的独特纵向数据集,在短期和长期内衡量成年人疾病对家庭就业结果的影响。
我们使用了两次印度人类发展调查(1993-94 年和 2004-05 年),其中包括一个由 10726 户家庭组成的平衡面板,以评估 15-64 岁成年家庭成员主要疾病对家庭就业结果的短期(在成年人生病发生的当年)和长期(在成年人生病发生后的 11 年)影响,使用多种匹配方法:最近邻匹配和逆概率加权,以及粗化精确匹配,以将就业结果与一组匹配的对照家庭进行比较。
受成年人疾病影响的农村家庭的劳动力参与率下降了 1-3%,工资就业减少了 4-15 天,工资收入减少了 374 到 837 印度卢比,与短期的匹配对照家庭相比。作为回应,受影响家庭的成年非病人成员的劳动力参与率大幅增加了 14-16%,以弥补短期的不足。在长期,受影响家庭的劳动力参与率也下降了近 1-3%。长期来看,工资天数和工资收入的下降幅度较小,且在各种方法中并不总是具有统计学意义。然而,长期内非病人成年劳动力参与率(4-6%)低于短期,但仍具有统计学意义。
长期影响的绝对值小于短期影响。这表明受影响的家庭在更长的 11 年时间跨度内通过应对和调整来缓解成年人疾病的直接影响。我们的研究还再次强调了改善印度农村地区受疾病影响家庭获得医疗服务和社会保障福利的机会的重要性,无论是在短期还是长期。
