  • did_multiplegt vs. did_multiplegt_dyn?

    l have a state-by-year panel data where my RHS treatment variable is turning on and off. So I'm trying to estimate dCDH estimator. However, I am running into issues where I am finding different estimates and "# of switchers" btwn the two dCDH command did_multiplegt vs. did_multiplegt_dyn. The code below is a very simple code that creates fake data and runs did_multiplegt and _dyn command.


    HTML Code:
    set seed 12345
    clear
    set obs 100
    gen time = ceil(_n/10)
    gen id = _n-10*(time-1)
    gen x = runiformint(0,1)
    gen y = rnormal()
    
    did_multiplegt_dyn y id time x
    did_multiplegt y id time x
    Is there a reason why the results are different. Which command should I use??
