Bayesian shrinkage priors for penalized synthetic control estimators in the presence of spillovers
存在溢出效应时惩罚合成控制估计的贝叶斯收缩先验
Synthetic control (SC) methods are widely used to estimate the effects of policy interventions, especially those targeting specific geographic regions, referred to as units. These methods construct a weighted combination of untreated units, forming a "synthetic" control that approximates the counterfactual outcomes of the treated unit had the intervention not occurred. Although neighboring areas are often selected as controls due to their similarity in observed and…
