论文摘要
我们重新审视了Equipo Anova最近的一篇论文的结果，他们声称有证据表明委内瑞拉进口的食品和药品与美国对委内瑞拉采取了对委内瑞拉的采用相关的食物和药物的进口，我们表明他们的结果表明，他们的结果是数据编码的结果和可疑的方法论，包括使用不合理的对反相同的功能的方法，这些方法是不合时宜的，这些方法是对反相反的反向效果，而不是对反相反的反向进行，而不是对反相反的反对，则是对反对的反应，这是对反对的造成的。在制裁时，该国粮食进口的四分之三以及对回归不连续方法的应用不正确。一旦纠正了这些错误，就会证明必需品进口的水平和变化率显着提高。
We revisit the results of a recent paper by Equipo Anova, who claim to find evidence of an improvement in Venezuelan imports of food and medicines associated with the adoption of U.S. financial sanctions towards Venezuela in 2017. We show that their results are consequence of data coding errors and questionable methodological choices, including the use an unreasonable functional form that implies a counterfactual of negative imports in the absence of sanctions, the omission of data accounting for four-fifths of the country's food imports at the time of sanctions and incorrect application of regression discontinuity methods. Once these errors are corrected, the evidence of a significant improvement in the level and rate of change in imports of essentials disappears.
