英文摘要：
For a panel model considered by Abadie et al. (2010), the counterfactual outcomes constructed by Abadie et al., Hsiao et al. (2012), and Doudchenko and Imbens (2017) may all be confounded by uncontrolled heterogenous trends. Based on exact-matching on the trend predictors, I propose new methods of estimating the model-specific treatment effects, which are free from heterogenous trends. When applied to Abadie et al.\'s (2010) model and data, the new estimators suggest considerably smaller effects of California\'s tobacco control program.

中文摘要：
对于Abadie et al.（2010）考虑的面板模型，Abadie et al.，Xiao et al.（2012）和Doudchenko and Imbens（2017）构建的反事实结果都可能被不可控的异质趋势所混淆。基于趋势预测因子的精确匹配，我提出了评估模型特定治疗效果的新方法，该方法不存在异质性趋势。当应用于Abadie等人（2010）的模型和数据时，新的估计器表明加利福尼亚州烟草控制计划的影响要小得多。
