Estimating the Average Treatment Effect of Social Safety Net Programmes in Bangladesh
利用模糊回归断点设计，控制选择偏差，估算孟加拉国社会安全网项目对贫困家庭福利的平均处理效应，为政策评估提供更可靠的因果证据。
Since the famine in 1974, the Bangladesh government and some national and international agencies have been providing food, or cash, or both, to poor households through the Social Safety Net programmes. I seek to estimate how much these programmes affect the well-being of poor households. Most previous studies have estimated impacts of these programmes on calorie consumption, simply computing the raw differential. However, both observed and unobserved characteristics bias this treatment effect. Using fuzzy regression discontinuity (RD) design, I control for these selection effects.
