We present causal evidence of the long-term effects of the Vietnam War on household agricultural productivity. Using bombing intensity data and data on the intensity of Agent Orange and other chemical agents used during the War, we find that spatial differences in the intensity of the War can help explain differences in long-term household agricultural productivity. Our endogeneity-corrected estimates suggest that, in the long-term, a 10% increase in bombing intensity decreases rice productivity by 2.94% and total agricultural productivity by 3.21%. Results from a fuzzy regression discontinuity design suggest that Agent Orange intensity also had a negative effect on rice productivity. We find that economic production is a channel through which the intensity of bombing and Agent Orange have adversely affected long-term agricultural productivity, while social capital is a channel through which Agent Orange is linked to lower long-term agricultural productivity.

我们提供了越南战争对家庭农业生产力的长期影响的因果证据。使用轰炸强度数据和橙剂和战争期间使用的其他化学剂的强度数据，我们发现战争强度的空间差异可以帮助解释长期家庭农业生产力的差异。我们的内生性校正估计表明，从长期来看，轰炸强度增加 10% 会使水稻生产力降低 2.94%，农业总生产力降低 3.21%。模糊回归不连续性设计的结果表明橙剂强度也对水稻生产力产生负面影响。我们发现经济生产是轰炸强度和橙剂对长期农业生产力产生不利影响的渠道，
