我们在孟加拉国北部的未通电地区进行了一项实验性干预，以调查太阳能产品在提高儿童教育成绩方面的有效性。我们发现，经过处理的家庭用太阳能灯代替煤油照明产品，有助于减少家庭总支出。太阳能灯增加了孩子们在家学习的时间，尤其是在晚上和考试前。太阳能灯最初导致了入学率的增加，但随着时间的推移，这种影响逐渐减弱。然而，学习时间的增加和出勤率的初步改善并没有转化为学习成绩的提高。在接受治疗的家庭中改变太阳能产品的数量并没有改变这些结果。利用学校等级治疗强度的分析也没有证据表明溢出效应解释了“没有学习成绩效应”。这些发现表明，仅仅通过提供太阳能产品来改善家庭学习环境可能对儿童的教育成就影响有限。
We conducted an experimental intervention in unelectrified areas of northern Bangladesh to investigate the effectiveness of solar products in improving children’s educational achievement. We found that treated households substituted solar lanterns for kerosene-based lighting products, helping to decrease total household expenditure. Solar lanterns increased the children’s home-study hours, particularly at night and before exams. The solar lanterns initially led to an increase in school attendance, but this effect diminished over time. However, the increased study hours and initial improvement in school attendance did not translate into improved academic performance. Varying the number of solar products within the treated households did not alter these results. Analyses that exploited the school grade treatment intensity also provided no evidence suggesting that spillover effects explained the “no academic performance effects.” These findings suggest that improving the home-study environment solely through the provision of solar products may have a limited impact on children’s educational achievement.
