The Impact of Terrorism on Individual Well-Being: Evidence from the Boston Marathon Bombing
利用美国时间使用调查数据，结合回归断点与双重差分方法，发现2013年波士顿马拉松爆炸案导致个人幸福感立即下降三分之一标准差，负面情绪显著上升，但影响持续不超过一周。
Abstract A growing literature has concluded that terrorism affects the economy, yet less is known about its impact on individual welfare. This article estimates the impact of the 2013 Boston marathon bombing on well-being, exploiting representative daily data from the American Time Use Survey and Well-Being Supplement. Using a combined regression discontinuity and differences-in-differences design, with the 2012 Boston marathon as a counterfactual, we find an immediate reduction in well-being of a third of a standard deviation. In particular, happiness declined sharply and negative emotions rose significantly. While the effects do not persist beyond one week, they may entail adverse health and economic consequences.
