We used contingent valuation technique to estimate the parental willingness to pay for an episode of diarrhoea among 324 children of both sexes aged between five and seven years in two rural villages of Chennai in India. The aim was to examine if there was any gender bias in the parental willingness to treat children for a diarrhoeal episode, and if so to what extent. The willingness to pay was specified as a hedonic function of the duration and severity of an episode, and of parents' socioeconomic characteristics. The findings suggest that parents were willing to pay more to protect their male child compared to the female child suffering from a diarrhoeal episode. The median willingness to pay to avoid an episode for male and female children were calculated at Rs. 33.7 (approx. US$ 0.72) and Rs. 25.2 (approx. US$ 0.54) respectively - a difference of around 34%. After adjusting for the greater duration and severity of the illness, it was found that the difference between the two medians increased to 51%.
我们运用条件价值评估技术，对印度钦奈两个乡村中324名年龄在5至7岁的男女儿童出现腹泻时家长的支付意愿进行了估算。目的是检验在家长为腹泻患儿治病的支付意愿上是否存在性别偏见，若存在，程度如何。支付意愿被设定为腹泻发作时长及严重程度以及家长社会经济特征的享乐函数。研究结果表明，与患有腹泻的女童相比，家长愿意为保护男童支付更多费用。避免男童和女童出现腹泻发作的支付意愿中位数分别计算为33.7卢比（约合0.72美元）和25.2卢比（约合0.54美元）——相差约34%。在对疾病持续时间更长和严重程度更高的情况进行调整后，发现两个中位数之间的差异增至51%。
