Treatment Adoption Heatmap (Event Studies)

In lecture we visualized the Castle Doctrine’s staggered rollout with a heatmap. Now create one for STRV seed adoption in panel_gis.dta.

• Create the binary treatment indicator post_adopt from the first_seed variable you built in Exercise 4: gen post_adopt = (year >= first_seed) & (first_seed != .).
• Use heatplot to create a treatment adoption heatmap with districts on the y-axis and years on the x-axis:

   heatplot    post_adopt i.district_id i.year, ///
                   colors(white dkgreen) ///
                   ylabel(, labsize(tiny) angle(0)) ///
                   xlabel(, labsize(small) angle(45)) ///
                   ytitle("District") xtitle("Year") ///
                   legend(order(1 "No Seed" 2 "Seed Adopted")) ///
                   graphregion(color(white))
  

• Export the heatmap as a .png and input it into your Overleaf document.
