I had a quick skim through your notes but couldn’t see the part on the flaws you mention – on the whole you seem fairly upbeat about DinD. Could you give a more precise reference, please?
Hi Mohan, particularly Slide 20 onwards here: https://github.com/paulgp/applied-methods-phd/blob/main/lectures/13a_dind_foundations.pdf about pre-testing issues and parallel trend functional form issues.
Thanks!
