Twfe assumptions
Did you know?
Webmodels is computationally difficult, so simplifying assumptions that are likely to cause bias are often invoked to make computation feasible and specification tests are rarely conducted.

Webassumptions even in the case with only two time periods. In particular, we show that TWFE regressions can deliver poor estimates of the average treatment effect on the treated (which is the natural target parameter for DID identification strategies) for any of four reasons: (1) time-varying covariates that are themselves affected by Webmodeling assumptions in place of direct support from the data. Adhering to this structure would imply that in the setting of Figure 10.2a, it would be impossible to make data-based causal inferences about any of the observations. Figure 10.2b shows a scenario in which data-based inferences are only possible for the region of
