Difference-in-difference Analysis with multiple treatment periods

[Jules brenda]

Does anyone have a suggestion on how to perform a DID analysis with multiple treatment periods? Because when I generate a variable: relative treatment time (generated by subtracting the variable wanted from the survey year), I have the treatment group alligned where 0 is the time where the shock took place. But for the control group, just the survey year is available.

Thank you very much in advance for helping, I really appreciate it.

You can use the Callaway and Sant'Anna package for DiD with different treatment times
