This note revisits the role of time-invariant observed covariates in the Synthetic Control (SC) method. We first derive conditions under which the original result of Abadie et al (2010) regarding the bias of the SC estimator remains valid when we relax the assumption of a perfect match on...

We derive conditions under which the original result of Abadie et al (2010) regarding the bias of the Synthetic Control (SC) estimator remains valid when we relax the assumption of a perfect match on observed covariates. We then show that, even when the conditions for the first result are valid,...

Recent research on glass ceilings and sticky floors has focused on the magnitude of differences between groups in the upper and lower quantile cutoffs of the conditional wage distribution. However, quantile cutoffs for different groups are only weakly informative of representation. For example,...
