Hi, so I have just come across the SDID method and was wondering if I could use it. I have monthly data for about 25 states using CPS Individual Data. I have 1 treated state, 24 untreated states. There would be around 12-15 pre periods and about 5 post periods. Firstly is a way to aggregate (and is it advisable) the CPS data by state per month (I believe I have to do this for SDID). Once having done that would it be recommended to use SDID. Furthermore, would I be able to add controls such as changing wages.
Thankful for any suggestions.
