WebAs I understand it, the general DiD panel data setup with simultaneous treatment would look something like this: y i t = α 0 + α 1 Treat i + α 2 After t + δ ( Treat*After) i t + x i t ′ β + FFE + TFE + ε i t, where: Treat = 1 if in the treatment group, 0 otherwise. After = 1 if after policy intervention, 0 otherwise.
